Description

Sandy mulberry-corn interplanting method
Technical Field
The invention belongs to the technical field of agriculture and forestry, and particularly relates to a sandy mulberry-corn interplanting method.
Background
The mulberry is a woody plant for many years, has developed root system, is cold-resistant and drought-resistant, has strong adaptability and strong wind-proof and sand-fixing capabilities, and is an advantageous tree species for ecological construction. The mulberry is also a medicinal and edible plant, and the overground stem and leaf is rich in protein, flavonoid, alkaloid and the like, so that the mulberry is rich in nutrition, good in palatability and high in feeding value, and can prevent diseases and reduce the use of antibiotics after animals eat the mulberry leaves as feed. Therefore, the mulberry is planted with important ecological, economic and social values.
The planting of the mulberry comprises the steps of seedling raising, transplanting, pest control, water and fertilizer management, field management and the like. The seedling raising is mainly to cut high-quality branches and then to plant the branches, and the cut parts can be treated by a growth promoter; transplanting mainly refers to transplanting seedlings into planting lands, and applying water and fertilizer to soil before transplanting; the water and fertilizer management means that fertilizer and water are timely applied after the seedlings are transplanted, so that the growth of the seedlings is ensured; the field management means that measures such as weeding, insect killing and the like are carried out, so that the occurrence of mulberry diseases is reduced.
Since mulberry is liked to warm and moist climates, its demand for water is high, so mulberry planting, especially seedling mulberry planting, is a certain requirement for soil quality. For example, chinese patent CN106857161A discloses a high-efficiency planting method for mulberry, which is characterized in that soil is improved by using an improver before planting the mulberry, so that the content of trace elements and the like in the soil is increased, the soil fertility is improved, and the growth of harmful bacteria is inhibited. For example, a method for interplanting daylily in a mulberry field disclosed in China patent 109804882A needs to prevent water and soil loss in hilly areas by digging a fixed value ditch. However, for sand soil with serious water shortage, the method for preventing water and soil loss cannot meet the requirement, so that the survival rate of mulberry branch transplanting is not high, and therefore, the drought tolerance of the mulberry needs to be improved, so that the mulberry is suitable for the growth of dry sand soil.
