After aeration to release harmful gases in the soil, improve soil or soil wet hydrophobic properties, accelerate the long-term wet soil drying, improve the surface compaction or thatch thick soil infiltration capacity, promote the growth of root soil hit hole volume, improve the soil cation exchange capacity, and to improve the retention of soil nutrient and water, accelerate the decomposition rate of organic residue, so that the roots can absorb enough nutrients to thrive.
We usually suggest aeration once a year, in spring or fall.
草坪打孔后有利于释放出土壤中的有害气体，有利于改善土壤或疏水土壤的变湿特性，加速长期潮湿土壤的干燥，提高表面紧实或芜枝层过厚土壤的渗透能力，促进打出土卷后洞内根的生长，提高土壤阳离子的交换能力，并改善土壤对养分、水分的保持力，加速有机残渣的分解速度，从而让草根可以吸收充足的养分，能够茁壮成长。
我们通常建议一年一次草地打孔，可以选择在春天或者秋天。
