How can fruits and vegetables prevent premature aging
The common symptoms of premature aging of summer vegetables such as eggplant, pepper, tomato, cucumber, melon, and bean pods are: atrophy, slow growth, yellowing of leaves, late flowers and fruits, low yield, poor quality, and severe death of plants with premature wilting. The reason for this is due to high temperature, drought, waterlogging, lack of fertilizer and water, and serious diseases and insect pests. It is necessary to prescribe the right medicine and take effective measures to deal with it. 1. Drainage in Qinggou ditch, reduce water level in summer, and eliminate waterlogging. Improve the root growth environment, reduce pests and diseases, and avoid roots. Second, the scientific use of fertilizer to ensure that the need for fruits is a crop that requires more fertilizer and faster fertilizers. Therefore, it is necessary to use enough base fertilizer to ensure supply, especially at the seedling stage, flowering stage, maturity stage, and fruit harvesting after the first harvest. To top-dressing. The combination of nitrogen, phosphorus, potassium, and trace elements (boron, calcium, zinc, and iron) has a good effect on the restoration of plant vitality, the increase of second crop yield, and the prevention and treatment of premature aging. In the middle and late stages, extra-root fertilizers can also be conducted. Third, irrigation cooling, dissolved fertilizer promote long in the hot season, should be based on soil conditions and melon vegetable growth situation, timely furrow irrigation or sprinkler irrigation, in order to reduce soil temperature, temperature and leaf temperature, reduce the high temperature and heat encountered in the blade; Moisture, dissolve fertilizer, and facilitate root absorption. On the other hand, timely cultivating in the rain, breaking the knot, and maintaining the oxygen increase health promotion. Fourth, timely picking up the heart, promote the early maturity of pepper, eggplant, tomato, etc. After the harvest of the first loquat fruit, should be based on density, timely removal of the top heart and side of the heart, eliminate the "top dominance" and promote balanced growth of plants. When you close a line, you can use your heart and heart. When you do not have a line, you can only take your heart off. Cucumbers, melons, watermelons, etc. When the melon vines grow to a certain length, they can carry out topping and cut off the branches and axillary buds in the middle and upper parts, so that the nutrients can be concentrated and moved into the young fruits to promote rapid expansion. Beans, beans, etc., should be based on the characteristics of the species and the height of the shelf to grasp the topping. If it is a long vine species and a spring bean pod, it can be picked when the vine grows to about 2 meters, while the short vine and autumn beans are not topping. When picking the heart, the diseased leaves and dead leaves can be removed and brought out of the field to reduce the breeding of diseases and insects. V. Prevention of pests and diseases, robust growth Common diseases in summer vegetables include viral diseases, anthrax, downy mildew, gray ash disease, ulceration and aphids, red spider, and cabbage caterpillar. Because vegetables and fruits are people's daily foods, they should be particularly careful when using drugs, and they must not use pesticides with long-term toxicity and long-term toxicity to ensure the safety of people and animals. Regardless of pest control or treatment, it is not possible to spray medicine on the required number of days before harvesting. VI. Harvesting in a timely manner, mentioning that timely harvesting of vegetables and fruits in the morning can increase yield and increase economic returns. Like most fruits can be harvested when 80% mature, eggplant, beans should be harvested when 90% of mature is good.
