At present, the peppers grown in the summer are in their blooming and fruiting period, but the high temperature and rainy environment is not conducive to the growth of peppers, which is easy to cause waterlogging, and the high incidence of diseases can also lead to the death of peppers. The management of vegetable farmers in all aspects cannot be relaxed.
1. Waterlogging prevention. Pepper plants are most afraid of waterlogging, so you must grasp the timing when topping with water. The leaves are not severely wilted when exposed to strong light at noon, indicating that there is no drought, and watering is generally not required. Even if it is severely wilted, it depends on the weather, listen to the weather forecast (you can't water before rain), and water small water to prevent waterlogging and falling leaves after watering.
2. Cultivation and hoeing. Intertillage and hoeing can promote root development, especially after watering the plots, it is necessary to timely cultivating and hoeing. After cultivating, the ground should be leveled to prevent wind loss, loosen the soil, promote growth, and reduce disease.
3. Protect flowers and fruits. During the flowering period, spray Nadiwen + Rui Pei Le + Rui Pei Boron to control prosperity, promote growth, preserve flowers and fruits.
4. Topdressing timely. When 50% of the pepper trees are just sitting on small peppers, it is necessary to apply nitrogen and potassium fertilizer once, do not apply urea alone, so as to avoid growth and increase the infection of young tissues and pests.
5. Remove weeds. Weeds in pepper fields can be sprayed with herbicides to prevent weeds and pepper seedlings from being crowded, winning glory, competing for fertilizer, and removing or destroying suitable habitats for pests.
6. Disease prevention. Most of the diseases of pepper are spread by wind and rain, so it is necessary to spray to prevent it before and after the rain, and spray once every 7 to 10 days. Spray protective agents before rain and systemic agents after rain, and spray therapeutic fungicides if diseases are found.
The diseases that cause the "three fall" (leaves, flowers, and fruits) of peppers are mainly scab, leaf spot, anthracnose, virus, insects, and physiological diseases; the diseases that cause dead trees are mainly blight, verticillium wilt, roots Rot, bacterial wilt; fruit rot disease is mainly caused by anthracnose and sunburn. Scab, leaf spot, and bacterial wilt can be sprayed with 750 times solution of copper nitrohumate + 600 times solution of rust and Fumei; 1500 times solution of Tribuconazole tebuconazole spray for anthracnose; fluobacterium frost for epidemic diseases Mycovir 600 times solution + nitro humic acid copper 750 times solution, spray the lower part of the plant or irrigate roots; for root rot, use rust and humic acid 600 times solution + nitro humic acid copper 750 times solution, spray the lower part of the plant; virus Spray the back of the leaves with 20% moguanidine copper acetate.
