Clean up the ditches to remove stagnant water and lower the water table. Control the humidity in the field so that asparagus grows as much as possible in a drier environment, reducing the spread of fleshy root rot.
Ventilation and dehumidification pulls the membrane around the greenhouse to prevent the asparagus from inducing stem blight and other diseases under high temperature and high humidity.
Disease prevention and timely removal of dead branches, reducing disease occurrence; longer flooding time, the field can cut half of the leaf layer in the upper part of the plant, or re-feed the mother stem to reduce plant transpiration consumption.
After the submerged fertilization, the soil is easy to be knotted, and the fertilizer loss is large. After the water is reclaimed, the soil should be loosened as soon as possible to increase the soil aeration and reduce the humidity in the field. If necessary, the soil near the fleshy root of the asparagus should be dried and disinfected to promote the root growth. . Foliar application of new high-fat film + vegetable strong stem spirit, inhibit the replication of pathogens, reduce its resistance and dosage, and enhance the effect of pesticides. After 5 to 7 days, the topdressing of the roots can be carried out once. The root can be used for root irrigation with the application of micro-fertilizer. It can induce the absorption, digestion and release of nitrogen, phosphorus, potassium and various trace elements in the soil by asparagus, and enhance the positive energy of asparagus development. Optimize fruit quality and enhance the resistance of asparagus.
