Summer and autumn pepper breeding should be done five defenses
High-temperature hazard seedbeds should be well ventilated, be constructed with awnings, shaded with shade nets or non-woven fabrics, shaded with branches, and sprayed with muddy water on plastic films. After sowing, the nursery bed was covered with straw and the seedling cover was removed when 60%-70% of the seedlings emerged. Through the sunshade, the temperature is lowered and the light transmittance is reduced to facilitate the growth of seedlings. The storm-prevented rainstorms threaten the bed to have a high topography and have drainage ditches around them. In case of rainstorms, they can be drained in time. It is best to use the “one net and one film†covering method, that is, to cover the shade net on the plastic film, and its sunshade cooling and anti-rainstorm performance is better than that of a single shade net. Before the advent of heavy rain, the plastic film was pulled down, the air outlet was tight, and the soil was buried tightly around it to prevent rainwater from flowing into the seedbed and fixing the film line to prevent it from being blown away by strong winds. If the seedbed enters the water, the soil will harden and the unfavorable seeds will germinate and become unearthed, which can easily cause a large number of dead seedlings. Before the sowing of drought-proof hazards, test the seed germination rate, determine the seeding amount according to the test results, and sow or fully water the seedlings in the seedbed. Sewage can not use sewage, dirty water, preferably groundwater. Before sowing, seedbeds should be shaded and moisturized. According to the weather conditions, a small amount of water can be sprayed in the morning or evening with a watering can to prevent drought in the seedbed. The main reason for the prevention of disease is the lack of light. Photosynthesis is weak, there are few nutrients to be produced, and the temperature is high. Especially when the night temperature is high, the respiration is strong, and there is more consumption of nutrients, so that the dry matter content in the body is reduced, and nitrogen fertilizer and water are sufficient, resulting in leggy. In addition, the density of seedlings is too large, they block each other, lack of light, the seedbed is not ventilated, there is less light around the seedlings, only the top receives more light, prompting the rapid growth of young stems, but also cause leggy. Therefore, the seedbed should not be flooded and can only be sprayed with a watering can, the amount of watering should not be too large, keep the seedbed see dry see wet, and time seedlings and seedlings. As long as it does not rain, the shed film should be open for ventilation, light and humidity, and rainy days, to remove the shade net, leaving only plastic film to prevent rain, and strive for more scattered light. Pest Control In summer and autumn, virus, aphid, and cabbage caterpillars can easily cause harm. Therefore, we must pay attention to the prevention of pests and diseases when breeding. First, fertilize the organic fertilizer to be fully decomposed, the seedbed is treated with carbendazim or formaldehyde and other agents for disinfection. Seeds need to be soaked in warm water or treated with chemicals to avoid the occurrence of soil-borne diseases. The second is to sow the bait and kill the earthworm and other underground pests immediately after sowing. The third is to reduce the seedbed temperature in order to help prevent the occurrence of viral diseases. The fourth is to choose disease-resistant varieties. The fifth is using insect nets to raise seedlings. Yellow and orange trap boards are set inside the seedbed to trap and kill locusts. Sixth, it is timely to fight drugs, and commonly used agents include 75% chlorothalonil, 50% carbendazim, 70% mancozeb, 20% virus A, 1.5% Phytophthora, 50% thiram, 50% anti-influenza, 50% phoxim emulsion, 80% trichlorfon and so on.
