草坪坪床建设前的准备
Preparation of lawn bed before construction
1、清理场地
1. Clean up the site
清理场地主要是为了将影响草坪生长的杂物清除，例如碎石、树枝和垃圾等。将土壤表面30厘米以上的杂物清除，确保坪床的质地疏松、平整、透气。如果有残留其它植物的地下根，也要一并清除。否则腐烂后会使地面形成洼地。
Cleaning up the field is mainly to remove the debris that affects the growth of the lawn, such as gravel, branches and garbage. Remove the debris above 30 centimeters on the surface of the soil to ensure that the bed is loose, smooth and breathable. If there is a residual root of other plants, it is also to be removed. Otherwise, it will cause the ground to form a low-lying ground.
2、清除杂草
2, weed out weeds
要建好草坪就离不开杂草的清除，杂草的问题必须先解决好才行。主要的防治手段为机械除草、除草剂除草和土壤熏蒸。
If you want to build a lawn, you can't get rid of the weed. The problem of weeds must be solved first. The main means of prevention and control are mechanical weeding, herbicide weeding and soil fumigation.
机械除草：主要是指靠人工定期修剪，手工拔除，除草机清除等物理除草方式，也是最传统的除草方法。这种方法的最大缺点是耗费人力，特别是面积大的区域，人工成本非常高。
Mechanical weeding: mainly rely on artificial regular pruning, manual removal, removal and other physical weeding weeding machine, weeding method is also the most traditional. The biggest disadvantage of this method is the cost of manpower, especially the area with large area, and the labor cost is very high.
除草剂除草：常用的除草剂有选择性除草剂和非选择性除草剂。除草效率高，人工费用要比机械除草低。缺点也很明显，使用不当会导致其它植物的伤害，对草坪环境产生影响。
Herbicide weeding: the commonly used herbicides are selective herbicides and non selective herbicides. The efficiency of weeding is high, and the labor cost is lower than that of mechanical weeding. The disadvantages are also obvious. Improper use can cause damage to other plants and affect the lawn environment.
土壤熏蒸：减少杂草最有效的方式，还可杀死土壤中的有害病虫。常用的熏蒸剂有棉隆、氯化苦、溴甲烷等。因为熏蒸剂都具有毒性，所以在使用时需要格外注意安全，对于使用人员还需要经过严格培训方可上岗。
Soil fumigation: the most effective way to reduce weeds, and to kill the pests in the soil. Fumigants are commonly used, such as methyl bromide chloropicrin, basamid. Because the fumigant is toxic, it is necessary to pay special attention to safety in the use of the fumigant, and for the use of the personnel also need strict training.
3、土壤PH值调整
3. The adjustment of soil pH value
草坪的适宜PH值一般在6到7左右。如果酸碱值出现波动就要及时调整。这个要根据所种植的草坪草种决定。若要降低PH值则加入硫酸铅，若是升高PH值则加入磷酸钙或石灰。
The proper pH of the lawn is about 6 to 7. If the acid and alkali value fluctuates, it should be adjusted in time. This is based on the lawn grass planted. If the pH is to be reduced, lead sulfate is added, and calcium or lime is added to the pH value.
4、施肥
4. Fertilization
在土壤当中加入适量的有机肥料，提高土壤中的养分，保证草坪的正常生长需要。一般有机肥有泥炭、厩肥、堆肥等。可根据草坪种植所在地条件自行选择。
A proper amount of organic fertilizer is added to the soil to improve the nutrients in the soil and to ensure the normal growth of the lawn. The general organic fertilizer, manure, compost, peat. It can be chosen according to the condition of the lawn planting.
5、平整翻耕
5. Smooth tillage
如果草坪的种植面积很大，建议用大型工作机械操作建坪。小面积区域可使用传统耕种工具人工作业。运动场应该中间隆起，以利于向四周排水。
If the lawn planting area is large, with a large mechanical operation establishment work advice. The traditional farming tools can be used in a small area. The playground should be raised in the middle to facilitate the drainage of the surrounding area.
6、排灌系统建设
6. Construction of irrigation and drainage system
排灌系统经常会因为造价原因被人所忽视。对于一块草坪而言，排灌系统都是建设工程当中不可缺少的一部分。尤其是运动场用草坪，如高尔夫球场和足球场等，排灌系统的作用至关重要。
Irrigation and drainage systems are often ignored because of the cost reasons. For a lawn, the irrigation and drainage system is an indispensable part of the construction project. Especially in sports fields, such as golf courses and football fields, the function of irrigation and drainage system is very important.
