High-temperature and rainy fruit vegetables prevent premature aging

In summer and autumn, in high temperature and rainy season, fruit vegetables such as pepper, cucumber and tomato are prone to premature senescence. The main symptoms are: atrophy of plants, yellowing of leaves, late fruit ripening, low yield, and severe plant death. Therefore, vegetable farmers must attach great importance to early prevention.

First, timely pruning. The main role of the topping is to prevent the plants from being long, reduce the excessive consumption of nutrients, and promote the plant's multiple results. After the first batch of peppers were harvested (at this time, the peppers were already in the cutting stage), the eight shoots growing on the four large branches growing near the base were cut off. At the same time, water and fertilizer management must also be strengthened so as to not only reduce excessive consumption of nutrients, but also allow good ventilation and light transmission to the four branches growing near the base, reducing the phenomenon of flowering and fruiting and increasing the yield of peppers. Cucumbers should be picked up in 25 leaves to promote the formation of melons, otherwise it is easy to cause obstruction of nutrient transportation. Tomato picking time should be after the fourth panicle flower set and leave two leaves on the ear, so as to avoid premature root failure and leaf curling.

Second, remove old leaves. The old leaves, dead leaves and diseased leaves in the lower part of the plant are removed in time to prevent field closure. In this way, not only the nutrient consumption of plants can be reduced, but also the spread and spread of diseases can be effectively controlled, and the ventilation and light transmission in the fields can also be facilitated, and the robust growth of plants can be promoted.

Third, early harvest. Fruit vegetables encourage the early harvest of fruits, which can reduce nutrient consumption and prevent premature aging.

Fourth, timely fertilizer. This is the key to preventing plant aging. The best time for topdressing after harvesting the fruit can generally be combined with irrigation to catch up to 1 to 2 times of human fecal urine or nitrogenous fertilizer and phosphate fertilizer. Cucumber topped with 10 kg per acre of diammonium phosphate, eggplant topped with 10 kg of urea per acre, pepper chase fertilizer should be more appropriate, per acre can be applied about 12 kg of diammonium phosphate, but the need to dissolve fertilizer in water topdressing It is not appropriate to plan for topdressing so as not to hurt the roots.

Fifth, irrigation cooling. In the hot summer season, irrigation can be performed according to the weather and soil moisture. Small water should be poured during irrigation to prevent damage to the root system of the ridge. At the same time, after the heavy rain, it is necessary to do a good job of drainage and flood control to ensure the normal growth and development of the seedlings.

Six, disease prevention and pest control. Fruit vegetables should pay attention to early control of aphids in time, generally available 20% cypermethrin emulsion 800 ~ 1000 times sprayed leaves. For cucumber powdery mildew 50% thiophanate-methyl 800-1000 times solution or 25% triadimefon WP 1200 times spray can be used for control of cucumber downy mildew, 40% alfaphospho-aluminum 300-400 times or 25% rosacea 1000 times spray control. Controlling tomato gray mold can be sprayed with 75% chlorothalonil wettable powder 600 to 800 times, or 50% thiophanate wettable powder 500 times. To control the tomato blight, it can be sprayed with 75% chlorothalonil 700 times solution or 50% cefotaxime 500 times solution at the beginning of the disease, sprayed every 7 to 10 days, and sprayed 3 to 4 times.
