Why does tomato have a snoring phenomenon? How to prevent tomato stems from hollowing out and wilting
Why does tomato have a snoring phenomenon? In the process of planting tomatoes, tomatoes will suffer from plant wilting due to physiological water shortage, bacterial wilt, blight, and the like. The physiological water shortage often occurs in the cold winter season, which will hinder the ability of the roots to absorb water and nutrients. Generally, as the temperature rises, the symptoms will be alleviated after the roots return to normal growth. Plant wilt caused by bacterial wilt and blight is different. In severe cases, production will be reduced or even lost. Therefore, a small series will focus on tomato bacterial wilt and blight. First, the occurrence and symptoms of bacterial wilt and blight 1, different germs Tomato bacterial wilt is a bacterial disease. After cutting the stem of tomato bacterial wilt, the surface is squeezed by hand and it will overflow the white bacterial liquid without stickiness. Tomato wilt is a fungal disease. After cutting the stem of tomato wilt disease, the sterilized liquid is cut by hand and the surface of the disease has a pink sticky substance when wet. 2, the incidence of growth period is different Tomato bacterial wilt began to develop in tomato plants at a height of 30 cm, while tomato wilt began to develop in the tomato flowering stage. 3, the phenomenon of wilting is different The diseased plant of tomato bacterial wilt is wilting during the day and can be recovered in the evening. After the plants die, the leaves remain green and do not change color. Tomato wilt is wilting during the day and will not recover in the evening. After the plants die, the leaves turn yellow. 4, different course of disease The path of tomato bacterial wilt is progressing rapidly, and the serious strain will die after about 7-8 days. The course of tomato wilt disease progresses slowly, and the diseased plants die after about 15-20 days. 5, the pathogens are different in winter form The pathogen of tomato bacterial wilt is mainly left in the field with the diseased residue, so the larger the amount of bacteria accumulated in the field, the more serious the disease. The tomato wilt pathogens overwinter with mycelium or chlamydospores in the soil or attached to the seed with the diseased residue. Second, measures to prevent the hollow and wilting of tomato stems 1. When planting tomatoes in winter and spring, attention should be paid to protecting and promoting the growth of roots of plants. The specific measures are: strengthening heat preservation, balanced fertilization, appropriate application of some amino acids or foliar fertilizers rich in trace elements, and some use to promote root growth. Other preparations; after the rainy weather and when the sun is strong, the cover should be gradually removed to avoid physiological water shortage in the tomato plants, thus causing damage to the plants. 2. Strengthen disease monitoring and prevent early treatment. Tomato bacterial wilt can be treated with 6% spring serotonin WP 300-400 times solution; 72% agricultural streptomycin WP 500 times solution; 30% DT WP 600 times solution and other roots. Tomato wilt can use 2.5% flavonoids (School) suspension 1000 times solution; 20% thiabend copper suspension (Longkes) 400-500 times solution; 77% copper sulfate wettable powder (can kill 1000 times liquid; 50% thiophanate WP (tobuzine) 800-1000 times liquid and other roots control.
