The function of a lawn perforator

After being used for a period of time, the lawn bed becomes compact and hardened due to compaction, watering and trampling. In this case, it will cause poor drainage of the lawn bed, severe oxygen deficiency at the root of the lawn grass, and low vitality of the lawn grass. The main purpose of drilling holes in lawns is to expand the surface area of the soil and increase the contact area between the lawn soil and the atmosphere. Promote gas exchange and enhance the aeration, water absorption and permeability of the soil; It is conducive to the growth of microorganisms and reduces harmful substances in the soil. Promote the growth of the root system inside the cave and the branches on the upper part of the cave roof; It can improve soil properties; The breaking of solid soil beds can accelerate the decomposition of the dead grass layer and organic residues on the lawn. Improving the response of the bedding to fertilizers is conducive to soil and water conservation
