Analysis of the causes of curling First of all, it is due to the high and low temperature. Temperature fluctuations cause imbalances in water uptake and transpiration in tomato roots. Second, it is caused by viral diseases. Temperature fluctuations, severe occurrence of aphids and greenhouse whitefly are very likely to cause the virus disease to occur and spread. According to the survey, most of the tomato greenhouses currently have varying degrees of viral disease. Again, it is due to a physiological disease. Some vegetable farmers focus on the application of nitrogen fertilizer, but neglect the input of phosphate fertilizer, potash fertilizer, and organic fertilizer, resulting in unbalanced supply and demand of tomato nutrients, causing physiological diseases, and causing tomato leaf rolling.
Prevention and control measures First, timely control of greenhouse temperature. In particular, due to high temperature caused by the phenomenon of tomato leaves lose water, in clear weather to increase the amount of air release, appropriate to reduce the temperature inside the shed, before and after noon on the shed film to cover the shade to reduce the temperature. Second, it is necessary to cut the viral disease vector. Prompt use of drugs to control aphids, greenhouse whitefly and other pests. The use of phytophthora, virus A and other agents spray to prevent viral disease, spraying once every 7 to 10 days, continuous medication 3 times. Third, we must scientifically manage fertilizer and water. When topdressing fertilizers, strict control of the amount of nitrogen fertilizers, appropriate addition of organic fertilizers and phosphate fertilizers, potash fertilizers, supplemental fertilizers such as boron fertilizers, calcium fertilizers, and the like, spraying leafy fertilizers such as green leaf treasure and potassium dihydrogen phosphate may be applied to increase the amount of leaf fertilizers. Absorption and utilization, enhance plant resistance.
