What to control the dead sweet pepper?

What to control the dead sweet pepper? Please introduce the prevention and control methods: first, the main reason for the death of sweet pepper is that the soil temperature within 15cm of the root surface layer is too high, and the second is that the soil moisture is too heavy within 20cm of the root surface layer. As long as one condition is met, it will cause a small number of dead trees, and if the two conditions are met at the same time, it will cause a large number of dead trees. In addition, too much fruit will also cause the death of trees. Second, preventive measures 1, to prevent 0-15 cm surface soil temperature is too high (1) small water frequently. In the sweet pepper fruiting period, water is watered every 6-8 days to make the 0-10 cm soil layer moist. Frequent watering with small water can reduce the topsoil temperature. (2) interplanting with high-stem crops. Sweet pepper belongs to the light plant, the light is strong and the temperature is too high, it is easy to die. The use of long vine beans or sweet corn and sweet pepper interplanting, every 2m sweet pepper row kidney beans or sweet corn can effectively reduce the light intensity and reduce the surface soil temperature. (3) reasonable close planting. Choose the corresponding planting specifications according to different planting levels, generally at 40 × 40-50 cm, so that the plants should be closed in the fruiting period, and try not to let the sun shine on the plastic film, so that the soil temperature of the topsoil layer under the plastic film will not rise too high. 2. Prevent overweight of 0-20 cm topsoil layer (1) adopt high soil moisture cultivation: adopt high border cultivation method to avoid excessive soil moisture caused by too much Rain Water. (2) to control the amount of water artificially, do not pour too much water (not too much water each time, about 2 kg per pond when transplanting, and about 1 kg per pond after transplanting, and about 0.5 kg per pond during the result period). Years of experience tells us that the soil moisture of sweet pepper in the result period is "no dry, no tide, no dead trees, suddenly dry, no tide, easy to die". (3) planting in summer and autumn should adopt high border cultivation or rain shelter cultivation (greenhouse), so as to avoid excessive soil moisture caused by too much Rain Water. 3. Salvage measures the characteristic of the dead plant of sweet pepper in the fruiting period is that the more the result, the more serious the dead tree. When the plants in the early stage of wilting appeared in the field, the effect of the drug was very poor, even ineffective. According to many years of field experience, the effective way is to immediately remove the fruits to be harvested, reduce the amount of fruit, and the plants at the initial stage of wilting can return to normal growth.
