In summer and autumn, weeds grow vigorously. Whether it is a natural grass orchard or an artificial grass orchard, it must be mowed in time and covered on the spot.
In addition to protecting water and drought, and increasing microbial activities, grass mulching has the effects of no light under the grass, so weeds no longer grow, and after the covered grass rots, the organic matter of the topsoil increases, the soil structure is significantly improved, the fruit trees grow robust, and the output doubles. Some people think that mulching will intensify pests, but in fact, many pests inhabit the grass after mulching. When preventing insects, pay attention to spraying on the grass to achieve a concentrated killing effect, but to reduce the pest damage.
The root system is distributed in the soil, and a large number of roots take place from 10 to 15 cm below the surface. Why is there less root in the live soil near the surface? This is because the soil in this part has good air permeability and is rich in effective nutrients. However, the moisture and temperature conditions are very unstable throughout the year, affecting the growth and survival of roots. Grass mulching can transform this unstable layer into a soil layer with more stable water, fertilizer, air and temperature conditions, and is also an important way to expand the root distribution layer.
