Second, to inhibit the growth of weeds Rat grass is a kind of self-sown grass, the plants can inhibit the growth of weeds, the entire summer does not require mowing. In grassy orchards, weeds such as purslane, goosegrass, bermudagrass and crabgrass were significantly reduced. According to the results of the survey, the inhibition rate of weeds on rat grasses was over 90%, and weeding was eliminated, and weeding was eliminated. The application. In 1 year, 5-6 times of labor cost for sward and loose soil can be reduced.
3. Increased soil nutrients Available nitrogen, phosphorus and potassium are the direct sources of nitrogen, phosphorus and potassium nutrients required for the growth and development of fruit trees, reflecting the actual supply capacity of nitrogen, phosphorus, and potassium nutrition in soil. The actual supply capacity of nitrogen, phosphorus, and potassium. Rat grass has a well-developed root system. Roots grow densely in the soil. After the growth period and the root system rots and rots, it maintains the permeability of the soil, prevents the water in the ground area, and maintains the ventilation. The role of root exudates and the presence of a large number of soil microorganisms and soil animals (蚯蚓), slow or insoluble nutrients in the soil can be converted into fast-acting or easily soluble nutrients, and promote the absorption of nutrients by fruit trees.
Fourth, improve the orchard soil organic matter content Soil organic matter is the material basis of soil fertility, is the main source of various nutrients, especially nitrogen and phosphorus, is an important indicator of the level of soil fertility, some orchards soil organic matter content is low, lodging in the orchard After the fermented and decomposed plants of the dead rat grass, they can supplement the organic matter in the soil and improve the physical and chemical properties of the soil.
V. Maintaining Soil Moisture Water is an important ecological factor for the survival of fruit trees. It is closely related to the life activities of fruit trees. All physiological activities of fruit trees are completed with the participation of water. Severe water shortages are detrimental to fruit tree growth and results. Sap can increase soil moisture content, especially can significantly increase soil moisture content of 0-20 cm, creating a good moisture condition for the root development of fruit trees. After the rat grass has fallen to the ground, it is covered on the ground. On the one hand, it prevents evaporation of soil moisture, avoids sun exposure on the ground and enhances the ability of drought resistance of fruit trees. On the other hand, under the condition of grass, the soil pellet structure is good, and the ability of conserving water is greatly enhanced. The water retention effect.
Sixth, to improve the orchard soil structure For a long time the apple orchard soil fertility management to clear the main, it is a strong labor force cultivator weeding, time-consuming work, damage to the soil structure, surface soil temperature changes, serious soil erosion; surface soil exposed, soil Large amount of water evaporation, poor water retention capacity, reduced soil moisture content; soil organic matter can not be supplemented and made it severely fatigued; fruit trees in shallow soil absorb a lot of damage to the root system, tree vigor is weak, diseases and pests increase, affecting yield and quality. After planting grass in the orchard, the orchard can reduce the soil bulk density of the orchard, increase the porosity of the soil capillary and non-capillary porosity, promote the formation of soil aggregate structure, improve the soil structure, and preserve the aeration, water permeability, water storage, and nutrient of the soil and rat grass. Release has a good effect, directly affecting soil moisture movement and fruit tree growth and development.
VII. Increasing yield and quality Rat grass improved the soil environment and the microclimate of orchards, promoted the growth and development of fruit trees, and improved fruit yield and quality.
