Field management of sweet peppers in the rainy season

Reuse fertilizer before the arrival of the rainy season, it is necessary to re-apply chemical fertilizer, 25-30 kg of ammonium diammonium sulfate or 15-20 kg of urea per mu, to prevent dehydration during the rainy season, can also be applied after each heavy rain urea 5 kg per acre . Fertilizer fertilizer should be evenly spread on the ground when dressing fertilizer, and should not be sprinkled on the leaves to prevent fertilizer.

Timely watering should be selected in the morning. At this time, the ground temperature, temperature and water temperature are all relatively low, which is not easy to cause harm to the plants. Watering before and after noon is strictly prohibited. The weather is sultry. After the rainfall, the pouring garden should be implemented. That is, immediately after the rain stops, it should be poured with well water, poured quickly, and be poured with the row to prevent the roots and stuffy heat from causing the leaves to fall off. Even after a few days of stormy weather, it is necessary to pour two small waters on the next day in order to reduce the temperature and protect the roots. Watering should pay attention to the sky, watering in time when drought does not rain, and strive to avoid rainfall, in case of root suffocation and induced disease.

After timely drainage of rainfall, drainage should be promptly conducted to prevent water from forming in the field, so that the rain can stop the water. When the soil is set, it should be covered with a small high-ridge or sorghum film to facilitate irrigation and drainage. If the humidity is too high, it is necessary to plan in time to increase the permeability of the soil and prevent water accumulation and soil oxygen deficiency, resulting in yellowing, defoliation, rooting and disease of the leaves.

Cultivated grassy weeds in the rainy season Weeds should be grown shallow or artificially to prevent damage to the roots of peppers, affecting the ability to absorb and causing disease infections.

The top-dressing fertilizer can be sprayed with 0.2% potassium dihydrogen phosphate, 0.1% urea, and 0.2% zinc sulfate mixture for many times, which can not only supplement nutrients, but also reduce the body temperature, accelerate photosynthesis, and promote fruit setting.

After dealing with hailstorms in response to locust plagues, the injured leaves and fruits should be promptly removed to reduce nutrient consumption, promote new branches, and spray pesticides and fertilizers in time.

Prevention of Pests and Diseases During the high-temperature rainy season, soil and air have high humidity, which easily leads to disease epidemics. Diseases caused by fungi have epidemics and anthrax. The key to prevention and control of diseases is flood control. When diseased plants are found in the field, it is necessary to promptly spray Ank-Manganese Zinc, Redomer, Prochloraz, Metalaxyl, etc. Pharmacy. Diseases caused by bacteria are scab, bacterial wilt, and soft rot, which are generally controlled by agricultural streptomycin or neomycin, or bactericide or DT fungicide. The key to the prevention and treatment of viral diseases is the prevention and control of aphids. When a diseased plant occurs in the field, virus A is sprayed and a suitable amount of foliar fertilizer is sprayed.
