In recent years, the summer vegetables have benefited well, and a considerable number of vegetable farmers have adjusted the summer vegetables. However, in the hot summer, high temperature and strong light bring great inconvenience to vegetable management. Vegetables are prone to adverse symptoms such as sunburn, flowering and fruiting, deficiency, and phytotoxicity. The reporter suggested that the current shed greenhouse vegetable management focus on the following three points:

It is resistant to high temperatures and strong light. If the vegetable in the shed is exposed to high temperature and strong light for a long time, it is prone to high temperature obstacles, such as cucumber wilting and tomato umbilical rot. In short, vegetable farmers should beware of high temperatures and strong light on the vegetables in the shed. The solutions are as follows: cover the sunshade net, splash mud or ink, spray the cooling agent, etc. In addition, because the temperature difference between day and night is too small, it is easy to cause the plant to grow up. It is recommended that the vegetable farmers spray the love to receive 1500 times to adjust.

Prevent pests and diseases. As the temperature in the shed rises, the gray mold, sclerotinia, and cotton rot that are suitable for low temperature and high humidity conditions are gradually reduced, which makes powdery mildew and bacterial diseases become popular. It is recommended to spray chlorothalonil 600 times and streptomycin 3000 times in 5-7 days to prevent various diseases. Virus disease should be strengthened under high temperature and drought conditions. Virus A500 times + Ningnanmycin 300 times + zinc leaf fertilizer can inhibit the occurrence and prevalence of viral diseases. For pests, it is recommended that vegetable farmers focus on the prevention of whitefly, thrips, and aphids. In addition to physical and biological control methods, vegetables, imidacloprid, scorpion, and avermectin can be used for prevention and treatment.

Prevent phytotoxicity and fertilizer damage. Vegetables are under high temperature and strong light, and their own metabolism is strengthened. If the spraying or sputum anthers are still diluted according to the winter, it is easy to cause leaf phytotoxicity and hormone poisoning; the amount of fertilizer and fertilizer is too large, and it is easy to cause Fat damage occurs. Here, it is recommended that friends of vegetable farmers should use drugs cautiously, especially anthers or plant growth regulators with a controlling effect; when applying fertilizer, pay attention to balanced fertilization, formula fertilization; foliar topdressing, with trace amounts of boron, calcium, magnesium, etc. The main fertilizer is the element.
