Since the price of peppers last year was higher, the purchase price per kilogram was generally between 4-5 yuan. The income of farmers with higher technical level of per acre was about 10,000 yuan. Therefore, many farmers are now ready to purchase and grow peppers. They hope to have a good harvest early; however, it is easy to cause peppers to die due to high temperatures in summer and heavy rain. Therefore, farmers should be reminded to take precautions at an early stage to avoid losses. Barbecue wire Grill Grate is made of high quality 304 stainless steel, never rusting and durable.

First, the reason for the death
1. Bad environmental conditions
1Climate factors continue to be high temperature and drought Light intensity is strong or heavy rain suddenly turns fine.
2 soil factors low terrain, high groundwater level, poor drainage, soil permeability, poor tillage, soil compaction; soil, thin soil, sticky plant, slow growth, malnutrition, weak growth, poor disease resistance
2, the variety selection is improperly planted large fruit, large leaf varieties or selected heat-resistant varieties.
3, continuous cropping the same field every year to plant pepper or with melons, Solanaceae crops as a latent source of bacteria.
4, the disease occurs caused by the infection of the bacteria caused by the summer of the dead plants of pepper is mainly caused by the combination of several diseases such as blight, disease, virus disease.
Second, prevention and treatment methods
1. Select varieties of mid-late maturing varieties that are heat-resistant, disease-resistant, and long-lived. In general, small fruit varieties are more resistant to heat-resistant and disease-resistant leaves than large-leaf varieties. Therefore, it is best to choose red pepper, pepper, or small pepper varieties in summer.
2, seed treatment, soak the seeds in warm water at 55 ° C for 15-20 minutes and then soak for 6-8 hours in normal temperature water. After the seeds are full of water, drain the water and wrap it with a damp cloth for germination. After 80% of the seeds are exposed, the seeds are sown. This can effectively kill some germs.
3, reasonable rotation to avoid the continuous cropping with melon, solanaceous vegetables can be carried out with rice, cruciferae, legumes and other crops for 2-3 years. If the previous work is not the best for paddy fields, it will be used for a month or so to kill the pathogens and 25-30 kg of lime per acre when it is used. This will have a certain effect on reducing disease and preventing dead seedlings.
4, strengthen the field management to implement sorghum planting, reasonable planting, rational use of water, timely drainage, cultivating loose soil to prevent excessive humidity, increase the application of phosphorus and potassium fertilizer on the basis of the application of base fertilizer, and increase the disease resistance of the plant.

6. Change irrigation methods to promote drip irrigation, sprinkler irrigation and seepage irrigation to reduce soil and air humidity, so that the soil is in a dry state to enhance the resistance of pepper roots; if the weather is hot, if the water is flooded with water, the soil moisture saturation is poor and the pepper roots are suffocated and died. The plant aging pathogens are aggravated by the spread of waterborne plants.
7, chemical control in the high temperature and high humidity season should be timely use of drugs for prevention and treatment with 50% metalaxyl manganese zinc wettable powder 700 times liquid or 50% nail cream copper wettable powder 700 times liquid and other epidemic disease; with 25% methyl thiophanate Wettable powder 1000 times liquid or 25% toxic mycelium WP 1500-800 times liquid and other anti-blight diseases; spray 200-300 times liquid 5% bacteria poison clear or 1000 times liquid potassium permanganate anti-virus disease and above pesticides Spray 3-4 times a day or so every 7 days or so and pay attention to the rotation of the medicine.
