1, Qinggou drainage, lower water level. Rainy summer. It is necessary to dredge field trenches, 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 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 later stage, extra-root fertilizer can also be applied. 3, irrigation cooling, soluble fertilizer promote long. In the hot season, furrow irrigation or sprinkler irrigation should be conducted in time according to soil conditions and melon vegetable production status 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, supplement water and fertilizers to facilitate root absorption. On the other hand, timely cultivating in the rain, breaking the knot, and maintaining the oxygen increase health promotion. 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. Cucumbers, melons, watermelons, etc., when the melon vines grow to about 25 leaves, can be picked up and cut off the middle and upper branches and axillary buds, so that concentrated nutrients transported to the young fruit to promote its 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 topping, the diseased leaves and dead leaves will be taken out of the field to reduce the breeding of diseases and insects. 5, control pests, robust growth. Common diseases and pests of vegetables in summer include viral diseases, anthrax, gray mold, ulceration and aphids, red spider, larvae, and cotton bollworms. Because vegetables and fruits are people's daily foods, they must be used with caution. It is strictly forbidden to use pesticides with long-term toxicity and long-lived 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 harvest. 6, timely harvest, mention the morning market. Harvesting fruits and vegetables at the right time can produce bumper crops and increase economic efficiency. For example, most fruits and vegetables can be harvested at 80% maturity, solanaceous fruits. Beans should be harvested when it is mature.
