Before the arrival of heavy chemical fertilizer rain season, it is necessary to re-apply a chemical fertilizer, applying 25-30 kg of diammonium sulfate or 15-20 kg of urea per mu to prevent de-fertilization in the rainy season, or 5 kg of urea per acre after each heavy rain. . When topdressing, the fertilizer should be spread evenly on the ground, and should not be scattered on the leaves to prevent damage.
Watering and watering should be carried out in the early morning. At this time, the ground temperature, temperature and water temperature are low, which is not easy to cause damage to the plants. It is strictly forbidden to water before and after noon. The weather is sultry. After the rain, the sloping garden should be implemented. That is, immediately after the rain stops, the well water is used for shallow pouring and fast pouring, and it is accompanied by the pouring to prevent the roots and sultry heat from causing the leaves to fall off. Even after a rainy day, it should be poured twice a day in order to reduce the ground temperature and protect the roots. Watering should pay attention to the sky. When it is raining for a long time, it should be watered in time, and strive to avoid the rain to prevent root suffocation and induce disease.
After draining the rain in time, it is necessary to drain in time to avoid the formation of stagnant water in the field, so that the rain should be stopped. When the soil is prepared, it should be covered with small high ridge or high mulch film to facilitate irrigation and drainage. If the humidity is too large, it should be planned in time to increase the permeability of the soil, prevent water accumulation, soil hypoxia, resulting in yellowing, defoliation, roots and diseases.
Weeds in the rainy season of cultivating weeds should be shallow or artificially weeded to prevent damage to the roots of peppers, affecting the absorption capacity and causing disease infection.
The external top dressing can spray 0.2% potassium dihydrogen phosphate, 0.1% urea and 0.2% zinc sulfate mixture on the leaf surface, which can not only supplement the nutrition, but also reduce the body temperature of the plant, accelerate photosynthesis and promote fruit setting.
In response to the hailstorm encountering hail, the injured leaves and fruits should be removed in time to reduce nutrient consumption, promote the extraction of new branches, and timely spraying, topdressing and watering.
Prevention of pests and diseases During the high temperature and rainy season, the soil and air humidity are high, which may lead to disease prevalence. Diseases caused by fungi include diseases and anthrax. The key to the prevention and control of epidemics is flood control. When disease plants are found in the field, they should be sprayed in time to Anke ~ Manganese Zinc, Lei Dumir, Can Kill, Antivirus, Metalaxyl, etc. Pharmacy. Diseases caused by bacteria include scab, bacterial wilt, and soft rot. Generally, it is sprayed with agricultural streptomycin or neomycin or can be killed or DT fungicide. The key to the prevention and treatment of viral diseases is to control the aphids. When the disease occurs in the field, the virus A is sprayed, and the appropriate amount of foliar fertilizer is sprayed.
