草坪的生存发育需要从土壤中吸取氧气,发育健全的草坪能够得到它们所需的氧气,因为土壤中的蚯蚓通道能输送有机物,并使土壤保持松散,便于贮存空气、肥料和水分。如果你的土壤有机质含量很低,或者因长期使用而变得板结起来,那么通过打孔来增加土壤的透气性会是很有益的。打孔必要性的测试测试土壤的板结度,可以拿一个较大一点螺丝刀或较坚硬的桩子插入土壤,如果很难插入,说明草坪的土壤太板了,需要进行打孔。较理想的是春天打一次,初秋 The lawn’s survival and development require oxygen from the soil. Well-developed lawns provide the oxygen they need because earthworm channels in the soil transport organic matter and keep the soil loose for easy storage of air, fertilizer and moisture. If your soil has a low organic matter content or becomes compounded by long-term use, it can be beneficial to increase the permeability of the soil by drilling holes. Testing for the Necessity of Punch Testing Soil compaction can be done by inserting a larger screwdriver or harder stake into the soil. If it is difficult to insert it, the soil of the lawn is too plate-shaped and requires drilling. More ideal is a spring fight, early autumn
