　　草坪施工的内容，就是要求根据已确定的设计来完成草坪开辟和种植过程。在这一施工过程中，要搞好土地整理工作，在准备好土壤的同时，要施好底肥和防虫害农药，平整好土地，布置好排水灌溉设施。种植方法有播种法、栽植法、铺草块和铺草卷4种方法。播种法要做好选种、种子处理工作，确定播种时间和播种方法；栽植法要确定好栽植时间、选择好草源、掘草栽植；铺草块和铺草卷要经过选择草源、确定草块、草卷大小规格、运输及存放、铺植等环节。不同的铺植方法都有各自的优点和缺点，在铺植草坪时，要根据实际情况，选择合适的栽植方法，使之产出经济优质的草坪。

 

Lawn construction's content, is required to complete the lawn according to established design and planting process. In the construction process, to improve land consolidation work, in the soil at the same time, ready to give better fertilizers and insect pests prevention of pesticide, flat land, decorate good drainage irrigation facilities. Shop with seeding, planting, planting method, blocks and volume 4 methods of turf grass. Seeding method to do a good job in selecting seeds, seed treatment, seeding time and planting method; Planting method to determine the planting time, choose good source, dug grass planting grass; Piece of turf and grass rolls will source selected grass, grass, grass volume size specification, transportation and storage, shop, etc. Different spread planting method has its own advantages and disadvantages, in the shop, when planting lawn, according to the actual situation, choose the appropriate planting method, make the output of economic quality lawn. 

 

　　1精细整地

 

1 fine soil preparation 

 

　　栽种草坪，必须事先按设计标高整理好场地，主要操作内容包括挖（刨）松土地、整平、施肥等，必要时还要换土[1]。对于有特殊要求的草坪如运动场草坪还应设置排地下水设施。草坪植物的根系80%分布在40 cm以上的土层中，而且50%以上是在地表以下20 cm的范围内。虽然有些草坪植物能耐干旱，耐瘠薄，但种在15 cm厚的土层上，易导致生长不良，应加强管理。为了使草坪保持优良的质量，减少管理费用，应尽可能使土层厚度达到40 cm左右，在小于30 cm的地方应加厚土层。对于含有砖石等杂质的土壤，虽然对草坪植物生长没有多大影响，但妨碍管理操作，应将杂物挑（拣）出来，必要时应将30～40 cm厚的表土全部过筛。如果土中含有石灰等有害于草坪植物生长的物质，则应将40 cm厚的表层土全部运走，另外换上砂质壤土，以利于草坪植物的生长发育[2]。

 

Planting lawn, must tidy up in advance according to the design elevation area, main operations include dig (plane) pine land, leveling, fertilizing, etc., also in soil [1] when necessary. For a lawn with special requirements, such as playground lawn discharge groundwater facilities shall be set up also. Lawn plant 80% of root system distribution in over 40 cm soil layer, and more than 50% is in the range of 20 cm below the surface. Although some lawn plant ability to drought and barren resistance, but in 15 cm thick soil layer, the poor can lead to growth, should strengthen the management. In order to keep the lawn fine quality, reduce the management cost, should as far as possible make 40 cm soil layer thickness, should upset soil in less than 30 cm. For soil containing impurities such as masonry, while has little influence to lawn plant growth, but hinder management operations, it should be sundry pick (pick) to come out, when necessary, 30 ~ 40 cm thick surface soil should be full sieving. If the soil contains harmful in lawn plant growth substances, such as lime, 40 cm thick surface soil should be carted away entirely, and sandy loam, to facilitate the growth of lawn plant [2]. 

 

　　为提高土壤肥力，最好施一些优质有机肥料作基肥。施农家肥40～50 t/hm2，或施麻渣15~20 t/hm2。如需施磷肥可施过磷酸钙150～200 kg/hm2。不论施哪种肥料，都应粉碎并与土壤搅拌均匀，撒后翻入土中。但不要施马粪，因其中含有大量杂草种籽，会造成以后草坪中野草蘖生。为防治地下害虫，保护草坪蘖根，在施肥的同时施适量农药。均匀撒施，避免药粉成块状而影响草坪植物成活。

 

For improving soil fertility, it is better to give some high-quality organic fertilizer as basal. 40 ~ 50 t/hm2, farmyard manure or MaZha 15 ~ 20 t/hm2. For phosphate to calcium superphosphate 150 ~ 200 kg/hm2. No matter what kind of fertilizer, should be crushed with soil and stir well, sprinkle over the grave after. But don't give the horse dung, because it contains a large number of weed seeds, after can cause lawn weeds in rice. For the prevention and control of underground pests, protect the lawn rice root, at the same time of fertilizer application amount of pesticide. Uniform broadcast and avoid powder into squares and influence of lawn plant survival. 

 

　　完成以上工作以后，按设计标高将地面整平，并注意保持一定排水坡度（一般采用0.3～0.5 °的坡度）。场地当中千万不可出现坑洼之处，以免积水，最后用碾子轻轻碾压1遍。体育场草坪对于排水的要求更高，除应注意搞好地表排水（坡度一般可采用0.5～0.7 °）以外，还应设置地下排水系统。整地质量好坏是草坪建立成败的关键之一，必须认真对待。

 

After finish above work, according to the design elevation of the ground leveling, drainage slope and keep a certain (usually by 0.3 ~ 0.5 ° slope). Site of potholes, do not appear to avoid water accumulation, with treadmills gently rolling finally 1 times. Stadium lawn taller to the requirement of drainage, should be paid attention to in addition to improve the surface drainage (0.5 ~ 0.7 ° slope usually can use), should also set up the underground drainage system. Site preparation quality lawn establishment is one of the keys to success or failure, must be taken seriously. 

 

　　2 布置排水及灌溉系统

 

2 layout of drainage and irrigation systems 

 

　　草坪与其他场地一样，需要考虑排除地面水，因此在最后平整地面时，要结合考虑地面排水问题，不能有低凹处，以避免积水。草坪多利用缓坡来排水，在一定面积内修1条缓坡地沟道，其最底下的一端可设雨水口接纳排出的地面水，并经地下管道排走，或以沟直接与湖池相连。理想的平坦草坪的表面应是中部稍高，逐渐向四周或边缘倾斜。地形过于平坦的草坪或地下水位过高或聚水过多的草坪、运动场的草坪等均应设置暗管或明沟排水，最完善的排水设施是用暗管组成一个系统与自由水面或排水管网相连接。草坪灌溉系统是兴造草坪的重要项目。目前，国内外草坪大多采用喷灌法，为此，在场地最后整平前，应将喷灌管网埋设完毕。

 

Lawn like other sites, need to consider the exclusion of surface water, so at the last level off the ground, to considering the ground drainage problem, there can be no dips, in order to avoid water accumulation. Lawn using gentle slope to drain more, in a certain area to channel 1 gentle slope, the bottom can be set at the end of the rain mouth discharge of surface water, and the underground pipe line to walk, or to ditch directly connected to lake basin. Central ideal flat lawn surface should be slightly higher, gradually or sloping edge round. Terrain is too flat lawn or ground water level is too high or too much water lawn and playground lawn all should set up drainage tubes or gutter drainage, is the most perfect drainage facilities with drainage tubes to form a system with free water surface, or drainage pipe network is connected. The lawn irrigation systems is one of the important projects hing building the lawn. At present, most lawn sprinkler irrigation method is adopted, therefore, in the last of the field leveling, sprinkler irrigation pipe network shall be buried.

　　草坪排水供水设施敷设完成，土面已经整平耙细，就可以进行草坪植物的种植施工。草坪种植方式主要有草籽播种、栽植、铺砌草块、铺草卷等几种[3-4]。

 

Lawn drainage water supply facilities installation completed, soil surface has fine leveling scraper, can be the lawn plant plant construction. Lawn planting ways mainly include seed for sowing, planting, grass paving block, grass rolls several [3-4]. 

 

　　3.1播种法

 

3.1 seeding method 

 

　　利用播种繁殖形成草坪，其优点是施工投资最小，从长远看，实生草坪植物的生命力较其他繁殖法为强。缺点是杂草容易侵入，养护管理要求较高，形成草坪的时间比其他方法更长。一是选种。要选择优良合格的种籽，播种前应做发芽试验和催芽处理，以确定合理的播种量。播种用的草籽必须要选用正确的草种，以保证发芽率高，一般要求草籽纯度在90%以上，发芽率在50%以上。二是种子处理。为了提高发芽率，达到苗全、苗壮的目的，在播种前可对种子加以处理。如细叶苔草的种子可用流水冲洗；结缕草种子可用0.5%氢氧化钠溶液浸泡24 h，捞出后再用清水冲洗干净，最后将种子放在阴凉、干燥处晾干种皮即可播种；野牛草种子可用机械的方法搓掉硬壳。而羊胡子草籽的处理方法有2种：一种是流水冲洗96 h；另一种是40～50 ℃的温水浸种，并随时用棍搅拌，水凉后用清水冲洗，以除去种皮外面的蜡质，晾干种皮即可播种。三是播种。主要根据草种与气候条件来决定播种时期。播种草籽，自春季至秋季均可进行。由于各地气候条件不同，应因地制宜地选择最适宜的播种时间。冬季不特别寒冷的地区，以早秋播种为最好，此时土温较高，根部发育好，耐寒力强，有利越冬。草坪在冬季越冬有困难的地区，只能采用春播。但春播苗多易直立生长，播种量应稍多些。播种方法一般采用撒播法。先在地上做3 m宽的条畦，并灌水浸地，水渗透稍干后，用特制的钉耙（耙齿间距2～3 cm），纵横耧沟，沟深0.5 cm，然后将处理好的草籽掺上2～3倍的细沙土，均匀撒播于沟内。最好是先纵向撒1/2，再横向撒另外1/2，然后用竹扫帚轻扫1遍，将草籽尽量扫入沟内，并用平耙耧平。最后用200～300 kg的碾子碾压1遍（潮而黏的土，不宜振压）。坡地和大面积草坪建植可采用喷播法。为了使草籽出苗快、生长好，最好在播种的同时混施一些速效化肥，可施硫酸铵250 kg/hm2、过磷酸钙500 kg/hm2、硫酸钾125 kg/hm2。四是后期管理。播种后应及时喷水，水点要细密、均匀，从上而下慢慢浸透地面，浸透土层8～10 cm。第1～2次喷水量不宜太大，喷水后应检查，如果发现草籽被冲出时，应及时覆土埋平。2次灌水后则应加大水量，经常保持土壤潮湿，喷水不可间断。此外，还必须将草坪围护起来，防止因有人践踏而造成出苗严重不齐。

 

Use form lawn seed propagation, its advantage is construction investment minimum, in the long run, the health of lawn plant vitality than other breeding method. Defect is easily invaded weeds, maintenance management demand is higher, forms the lawn time is longer than other methods. One is to cultivate. Should choose qualified fine seeds, germination test should be obtained before planting and emergence, to determine a reasonable rate. With seed sowing must choose the right grass seed, to ensure that the germination rate is high, the general requirement seed purity over 90%, germination rate over 50%. Second, the seed treatment. In order to improve the germination rate, achieve the purpose of miao full, healthy, before sowing seed processing. Such as fine leaves and moss grass seeds available water flushing; Zoysia japonica CaoZhongZi available 0.5% sodium hydroxide solution soak for 24 h, take it out and then rinse off with clear water, finally put seeds in a cool, dry place dry seed can be sown; Buffalo CaoZhongZi mechanical methods are available to rub off scale. The sheep beard grass seed processing method has two kinds: one kind is 96 h water flushing; Another is 40 ~ 50 ℃ warm water soaked, and mixing with the rod, cold water wash, after to remove seed coat of wax outside, dry seed can be sown. 3 it is to sow. Mainly based on the grass and climate conditions to determine the seeding period. Planting seed, from spring to autumn. Due to different climate conditions around the, should adjust measures to local conditions to choose the most suitable sowing time. Not particularly cold winter region, in order to early autumn sowing seeds for the best, Mark Twain is higher, at this time the root development is good, strong tolerance to cold, winter. Lawn in winter winter is difficult, can only use spring sowing. But the spring sowing seedling is much easy to erect growth, seeding rate should be a little more. Planting method is generally by seeding method. First on the ground to do 3 m wide strip, and water immersion, water infiltration is a bit dry, use special rake (rake tooth spacing between 2 ~ 3 cm), vertical and horizontal Lou groove, groove depth of 0.5 cm, and then will deal with good seed mixed 2 ~ 3 times of fine sand, uniform seeding in the ditch. 1/2, it is better to the longitudinal and transverse again and another half, and then use bamboo broom swept gently 1 times will seed for as much as possible into a ditch, and flat palou area. Finally in 200 ~ 300 kg stone roller rolling 1 (wet and sticky soil, unfavorable vibration pressure). Slopes and large area lawn planting spray seeding method can be adopted. In order to make the fast grass seed emergence, growth is good, the best at the time of sowing mixed some phosphorus chemical fertilizer, can apply as 250 kg/hm2, 500 kg/hm2 superphosphate, potassium sulfate, 125 kg/hm2. Four is the late management. Sow shall promptly after water spray, water points to close, uniform, from top and bottom to soak the ground slowly, saturated soil layer 8 ~ 10 cm. 1 ~ 2 times amount of water shoulds not be too big, should be check after water, if it is found that were out of grass seeds, should be timely turns the soil buried. After 2 times irrigation should be more water, keep soil moisture, water completely. In addition, it must be the lawn palisade, prevent the emergence of serious caused by someone on. 

 

3.2栽植法

 

3.2 planting method 

 

　　用植株繁殖较容易，能大量节省草源，一般1 m2的草块可以栽成草坪5～10 m2或更多一些。与播种法相比，此法操作方便，费用较低，节省草源，管理容易，能迅速形成草坪。对于种子繁殖较困难的草种或匍匐茎、根状茎较发达的种类适合用此方法。

 

In plant breeding easier, source can save huge quantities of grass, generally 1 m2 block can be planted into the lawn grass 5 ~ 10 m2 or more. Compared with planting method, this method is easy to operate, low cost, saving grass sources, management easy, can quickly form the lawn. The grass seed breeding more difficult or stolons, rhizomes advanced type is suitable for using this method. 

 

　　一是栽植。全年的生长季均可进行栽植。但如果种植时间过晚，当年就不能覆盖地面，最佳的栽植时间是生长季中期，暖季型草宜在5—6月、冷季型草宜在4—9月种植。二是选择草源。草源地一般是事前建立的草圃，以保证草源充足，特别是分枝能力不强的草种。在无专用草圃的情况下，也可选择杂草少、目的草种生长健壮的草坪作草源地。草源地的土壤如果过于干燥，应在掘草前灌水，水渗入深度应在10 cm以上。三是掘草。掘取匍匐性草根，其根部最好多带一些宿土，掘后及时装车运走。草根堆放要薄，并放在阴凉之地，必要时可以搭棚存放，并经常喷水，以保持草根潮湿，一般1 m2草源可以栽种草坪5～10 m2。掘非匍匐性草根时应尽量保持根系完整丰满，不可掘得太浅，否则易造成伤根。掘前可将草叶剪短，掘下后可去掉草根上带的土，并将杂草挑净，装入湿蒲包或湿麻袋中及时运走。如不能立即栽植也必须铺散存放于阴凉处，并随时喷水养护，一般1 m2草源可栽草坪2～3 m2。四是栽草。分条栽与穴栽2种方法。条栽法比较节省人力，用草量较少，施工速度也快，但草坪形成时间比点栽的要慢。操作方法很简单，先挖（刨）沟，沟深5～6 cm，沟距20～25 cm，将草蔓（连根带茎）每2～3根为1束，前后搭接埋入沟内，埋土盖严，碾压、灌水，之后要及时挑除野草。穴栽比较均匀，形成草坪迅速，但比较费人工。栽草2人为1个作业组，1人负责分草并将杂草挑净，1人负责栽草，用花铲刨坑，深度和直径均为5～7 cm，株距根据不同草种而有所不同。呈梅花形（三角形）将草根栽入穴内，用细土埋平，用花铲拍紧，并随时顺势耧平地面，最后再碾压1次，及时喷水。

 

One is to plant. Year-round growing season for planting. But if time too late, that won't be able to cover the ground, the best planting time is mid growing season, warm grass type should be in season 5 - June, cold type grass should be planted in September 4,. Second, choose grass source. Grass source is generally established beforehand grass field, to ensure that the grass source is adequate, especially grass branching ability is not strong. In without special grass field, also can choose fewer weeds, purpose grass lawn for grass source of robust growth. Grass if the source of the soil is too dry, should be in front of the dug grass irrigation, water infiltration depth should be in more than 10 cm. 3 it is dug grass. Made creeping roots, the roots had better take some SuTu, dig after loading off in time. Grassroots stacked to thin, and in a cool place, scaffolding for may, when necessary, and water, to keep the grass wet, generally 1 m2 source can grow grass lawn 5 ~ 10 m2. Dig the non creeping roots should try to keep the root complete plump, not dug too shallow, otherwise easy to cause root damage. Before digging a blade of grass can be cut short, can be removed after digging under the grass roots with soil, and weeds will pick net, load in a wet sack on the wet calceolarias or shipped in a timely manner. If not immediately to plant must also spread out stored in shady and cool place, and wet curing at any time, usually 1 m2 source can be planted grass lawn 2 ~ 3 m2. Four is planted grass. Article points with hole planted two methods. Hydroponics is saves the manpower, use less grass, construction speed is fast, but slower than some planted lawn formation time. Operation method is very simple, first dig a trench (plane), groove depth 5 ~ 6 cm, groove from 20 ~ 25 cm, grass tendril (root and stem) every 2 ~ 3 to 1, lap around into a ditch, buried soil cover tightly, roller compaction, water, in a timely manner after rejects all weeds. Den plant is evener, forming lawn rapidly, but compared with the. 2 artificially planted grass one functional group, one person is responsible for the points of grass and weeds will pick net, 1 person responsible for planting grass, with flowers spade dig ditches, depth and diameter is 5 ~ 7 cm, planting distance varies according to different grass seed. Plum blossom in shape (a triangle) would grassroots planted into the cave, buried with fine soil plain, with flower shovel tight, conveniently Lou flat to the ground and at any time, and then rolling, spray water in time. 

 

 

 

　 3.3铺草块

 

3.3 pave grass pieces 

 

　　铺草块是用带土成块移植铺设草坪的方法，此法可带原土块移植，所以形成很快。除土冻期外，一年四季均可施工，尤以春、秋两季为好。各草种均适用，缺点是成本高，且容易衰老。

 

Grass block is laid into a piece of transplantation with soil lawn method, this method can take the original clod transplantation, so the form soon. In addition to the soil freezing period, all the year round all can construction, especially in the spring and autumn season two as well. Each grass are applicable, disadvantage is high cost, and easy to aging. 

 

　　一是选草源地。选择无杂草、覆盖度95%以上、草色纯正、生长势强，而且有足够大的面积为草源。二是掘草块。在选好的草源地上，事先灌足1次水，待水渗透后便于操作时，人工可用平锨或用带有圆盘刀的拖拉机，将草源地切成长块状，草块大小根据运输及操作方法而定，大致有以下几种：45 cm×30 cm、60 cm×30 cm、30 cm×12 cm，切口约10 cm深，然后用平锨或平铲起出草块即成。掘取草块应边缘整齐、厚度一致、紧密不散，这样才能保证草块的质量。草块带土厚度5～6 cm或稍薄些。三是运输及存放草块。草块掘好后，可放在宽20 cm、长100 cm、厚2cm的木板上，每块木板上放2～3层草块。装车时用木板抬，防止破碎，并靠近码放整齐。运至铺草坪现场后，应将草块单层放置，并注意遮荫，经常喷水，保持草块潮湿，并应及时铺栽。四是铺草块。铺草块前，应检查场地是否整平等准备工作情况，必须将一切现场准备工作做完后方可施工。铺草块时，必须掌握好地面标高，最好采用钉桩拉线作为掌握标高的依据。可每隔10 m钉1个木桩，用仪器测好标高，做好标记，并在木桩上拉紧细线绳。铺草时，草块的土面应与线平齐，草块薄时应垫土，草块太厚则应适当削薄一些。铺设草块可采取密铺或间铺，密铺应使缝隙错落互相咬茬，草块边要修整齐，互相衔接不留缝，草块间填满细土，用木拍拍实，使草块与草块、草块与地面紧密连接。间铺间隙应均匀，缝的宽度为4～6 cm。一定要保证铺平，否则将来低洼积水，会影响草坪生长。最后用500 kg的碾子碾压，并及时喷水养护，保持土壤湿润直至新叶开始生长，铺草时，若发现草块上带有少量杂草，应立即挑净，如杂草过多则应淘汰。

 

One is to choose grass source. Choose without weeds, grass coverage above 95%, color pure, strong growth potential, and has a large enough area of grass. 2 it is dug grass pieces. On selected grass source, water filling and foot 1 time in advance, after waiting for water permeability, easy operation, manual available flat shovel or use tractors with disc knife, cut grass source growth block, grass block size according to transportation and operation method, generally has the following kinds: 45 cm * 30 cm, 60 cm * 30 cm * 30 cm, 12 cm, about 10 cm deep incision, then use flat shovel or flat scooping up out of the grass. Made of grass piece should be neat, thickness consistent, closely, so as to guarantee the quality of grass piece. Grass block zone thickness 5 ~ 6 cm or slightly thin some. 3 it is grass, transport and storage. After digging a good piece of the grass, can be in a 20 cm wide, length 100 cm, 2 cm thick plank, each 2 ~ 3 layers of grass piece on the board. Loading on board to carry, prevent breakage, and close to pieces in order. To pave the lawn after the scene, should place the grass piece of monolayer, and pay attention to the shade, often water, wet the grass block, and should be planted. 4 it is piece of turf. Straw before, should check the site preparations for equality, must will all the preparation work done rear can construction. Grass block, must grasp the ground elevation, had better use screw pile anchor as the basis of a master level. Can be every 10 m nail a stake, with instrumental good elevation, completes the tag, and a stake in the taut cord. Grass, grass block soil surface should be flush with line, thin piece should be mat grass, grass block too thick should be appropriately cut thin some. Laying of grass piece may take between shop or shop, shop should make aperture scattered bite each other, grass of edge to tidy, connecting with each other without seam, fill the fine soil between grass block, use wood clap, make grass and grass, grass blocks is closely connected with the ground. Spread between the gap should be uniform, the width of the seam is 4 ~ 6 cm. Make sure smooth, otherwise the low-lying water accumulation in the future, will affect the growth of the lawn. Finally with 500 kg stone roller compaction, and hydraulic maintenance in time, keep the soil moist until grow new leaves, grass, if discover the grass block contains a small amount of weeds, should immediately pick net, such as too many weeds should be eliminated. 

 

　　3.4铺草卷

 

3.4 pave the grass rolls 

 

　　经育苗地培育出的草像地毯一样，可以卷起来运至工地，又像地毯一样铺开，并及时喷水养护，短时间内即可恢复生机，形成草坪景观。其优点是工期短、见效快，缺点是成本略高于其他草坪种植方法。

 

After the seedlings to grow grass, like a carpet can be rolled up and shipped to the site, and spread out like a carpet, and wet curing in time, in a short period of time can come back to life, form the lawn landscape. Its advantage is short period, quick effect, defect is the lawn planting cost slightly higher than the other methods. 

 

　　一是起草搬运。地毯式草卷长宽以1m为宜，一般每卷卷起的直径为15～20 cm，重约30 kg（含水量25%～30%），苗龄2个月即可卷起出圃。苗龄越长，根系透过无纺布数量越大，卷起时较费力，卷带床土越多，但不影响成活。搬运时可采用简易担架，应轻抬轻放避免撕裂。二是铺设。轻抬轻放的草卷边缘较整齐，依次铺设，地边地角处可剪栽补铺，接缝处靠紧踏实并适当覆土弥合，切勿边角重叠，否则会使上层接地不实，根系悬空，下层草苗被盖坏死，全部铺完后进行滚压。三是浇水。第1次水必须浇透，使之与土壤接实，便于向下扎根。然后撒上0.3 cm左右的加肥细土，再浇第2遍水，使根系间填实，有利缓苗复壮。2～3 d后根系代谢正常后，转入正常养护。

 

One is to draft the handling. Carpet grass roll width is 1 m, usually every roll roll up for 15 ~ 20 cm in diameter, weighing about 30 kg (moisture content 25% ~ 30%), age of seedling can be rolled up sizes of 2 months. The longer the age of seedling and root system through a number of non-woven fabric, the greater the roll up when more arduous, the take-up of bed soil, the more but do not affect survival. Can be used in the simple stretcher, avoid tear light should light up. 2 it is laid. Light up the light grass rolls edge is neat, in turn laid, juggle seed planted repair shop can be cut, the seams on tight steadfast and proper covering bridge, not overlapping edges, otherwise it will make upper ground false, roots dangling, lower grass seedlings were necrosis, all shop after rolling. Three is watering. First water must be put through, to that of the soil solid, easy to take root downward. Then 0.3 cm and the fine soil fertilizer, watered 2 times again, make root system between infill and favorable slow seedling rejuvenation. After root metabolism to normal after 2 ~ 3 d, into normal maintenance.
