1, Qinggou drainage, lower water level. In summer, it is necessary to dredge the field trenches, gutters and trenches frequently to eliminate waterlogging, improve the living environment in the rhizosphere, reduce pests and diseases, and avoid short roots.
2, scientific fertilizer, to ensure the need. Fruits and vegetables are plants that require more fertilizer and faster fertilizers. Therefore, base fertilizers should be used to ensure supply, especially in the seedling stage, flowering stage, maturity stage, and after the fruit is harvested. The combined application of nitrogen, phosphorus, potassium and trace elements (boron, calcium, zinc, iron) has a good effect on the restoration of plant vitality and the second batch of fruit production and prevention of premature aging. In the middle and later stages of production, extra-root fertilizers can also be produced.
3, irrigation cooling, soluble fertilizer promote long. During the high temperature season, furrow irrigation or sprinkler irrigation should be carried out in time according to soil conditions and the production trend of melons and vegetables in order to reduce soil temperature, air temperature, and leaf temperature, and reduce the high temperature and hot temperatures encountered by the leaves. At the same time, supplementing water and dissolving fertilizers will facilitate root absorption. On the other hand, timely cultivating in the rain, break the knot, and save oxygen to promote growth.
4, timely picking heart, promote premature. After harvesting the first loquat fruits, peppers, eggplants, tomatoes, etc., should be based on the density, timely removal of the top heart and the side of the heart, eliminate the "top dominance" and promote balanced growth of the plant, that is, when the seal line can be used to hit the top heart and side If you do not close the line, you will only take care of your heart. For cucumbers, melons, watermelons and other crops, when the melon vines grow to about 25 leaves, 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 transported to young fruit and promote rapid expansion. Beans, beans, etc., should be based on the characteristics of the species and the height of the stent to grasp the heart-picking, such as long-vine species and spring beans, can be picked up when the vine grows to about 2 meters. Shorter species and autumn beans are not topping. When picking the heart, the diseased leaves and dead leaves removed will be taken out of the field to reduce the breeding of diseases and insects.
5, control pests, robust growth. Summer vegetables common pests are toxins, anthrax, gray mold, ulceration and aphids, red spider, tobacco budworm, cotton bollworm and so on. Because vegetables and fruits are people's daily foods, they should be especially careful when using drugs. It is forbidden to use pesticides with long-term toxicity and long-term toxicity to ensure the safety of humans and animals. No matter whether pests or diseases are treated, they cannot be sprayed 10-15 days before harvesting. .
6, timely harvest, mention the morning market. Harvesting vegetables and fruits at the right time can produce bumper crops and increase economic efficiency. For example, most fruits can be harvested when they are ripe. Solanaceous fruits, beans, etc. should be harvested at 9 when mature.
