According to Xiaobian, the most prone season for premature puberty is summer. Many vegetables have premature aging and death due to temperature. Today, Xiaobian analyzes the performance and prevention methods of premature senescence of solanaceous vegetables.
Premature aging of solanaceous vegetables is also an important factor affecting yield. During the high temperature and rainy season in summer, the solanaceous vegetables are prone to premature aging. The symptoms are: plant atrophy, yellowing of leaves, late fruit ripening, low yield, and serious premature death of plants.
There are six ways to prevent premature aging: 1 timely picking. 2 Remove the old leaves. 3 early fruit collection. 4 timely topdressing. 5 irrigation and cooling. 6 Effectively control pests and diseases.
1 timely picking
After the first pepper is removed, the pepper is already in the rest stage. At this time, 8 branches growing above the four branches growing near the base should be cut off, and the management of fertilizer and water should be strengthened, which not only reduces nutrient consumption, but also reduces nutrient consumption. Moreover, the four branches with growth near the base are well ventilated, reduce the rotten fruit and increase the yield of the pepper; the tomato topping should leave 2 leaves on the fruit after sitting on the fourth layer, otherwise it will cause premature root failure and lower part of the plant. Roll leaves.
2 remove the old leaves
All kinds of solanaceous vegetables should be removed in time to remove the old leaves, dead leaves and diseased leaves in the lower part of the plant to prevent the plant from being closed. This not only reduces nutrient consumption, effectively controls the occurrence and spread of diseases, but also facilitates ventilation and light transmission, and promotes the robust growth of plants.
3 early fruit picking
The solanaceous vegetables advocate early harvesting, and the tomato harvesting period is harvested when the top of the fruit is just turned; the pepper is harvested in time before the green fruit is red; the eggplant is the oily appearance before the seeds turn brown. The color of this variety should be harvested.
4 timely topdressing
The best period for top dressing is 1-2 times after the fruit is harvested. It is best to apply the nitrogen fertilizer and phosphate fertilizer with the combination of watering and composting manure. Tomatoes are applied with 10 kg of diammonium phosphate per mu, 10 kg of urea is applied to the eggplant, and 12 kg of diammonium phosphate can be applied to the pepper.
5 irrigation and cooling
In the hot summer, irrigation can be carried out according to the weather and soil moisture to reduce the soil temperature, but small water should be used to prevent flooding. At the same time, after the heavy rain, it is necessary to drain and prevent flooding in time to protect the normal growth and development of the seedlings.
6 Effective prevention and control of pests and diseases
Botrytis cinerea can be sprayed with 75% chlorothalonil WP 600-800 times or 50% keiling WP 2000 times. In the early stage of the disease, eggplant immune disease can be sprayed with 75% chlorothalonil 700 times solution or 80% mancozeb 500 times solution, sprayed once every 7-10 days, and sprayed 3 times.
Vegetable planting often encounters planting problems such as pests and diseases. Some vegetables have premature aging when planted. If there is no reasonable management, it will seriously reduce the yield of vegetables. Therefore, the above-mentioned small-scale planting methods for preventing and curing premature senescence of vegetables, and all growers have a quick look. .
