Asparagus stem blight, once disease is difficult to treat, is currently a major enemy of asparagus cultivation, seriously affecting the production of asparagus and shortening the harvesting period.

First, early prevention. Asparagus stem blight usually occurs only on newly grown stalks, so it is necessary to use a bacteriostatic net to fight the drug 3 days before leaving the stem to sterilize the environment and grow new stems in a pathogen-free environment. "One night" is late watering. Stem blight is a high-humidity disease, and field humidity should be controlled. Forty-five days after asparagus stalks grew, the disease-resistance performance was significantly enhanced. In 40 days, no watering was required. Before pouring stems, sufficient water could be poured and fertilizer applied. Fertilizer was applied to slow release fertilizer to ensure fertilizer efficiency. Then cultivator loose soil.

Second, use high ridge cultivation to reduce humidity. It is advisable to use 2/3 of the furrows on the water surface when the ridge height is watered, so that the upper 1/3 of the upper ridge is kept dry and the stem blight germs cannot germinate. "One low" is the point of contact between the base of the stem and the ground.

Third, refers to the shoots of asparagus plant shoots in the ground to fight, hit evenly. "One click" means that the ground should be sterilized before leaving the stem.
Fourth, it is no watering within 40 days of leaving stems, and cultivating in time after raining to reduce the humidity in the field. "A wet" is a light watering. It can pour small water during shoots, which can increase the yield of asparagus and make the shoots crisp. During germination, the germs are not afraid to germinate, and the stems are harvested immediately after the shoots are grown. The pathogens do not have hosts and do not cause harm.

The fifth is spraying the medicine before watering. After the rain, it is sprayed again and again to prevent germs from germinating due to high humidity.
