1. Drain the drains and lower the water level. In summer, it is necessary to frequently clear the drainage ditch in the field to eliminate waterlogging, improve the living environment in the rhizosphere of vegetables, and reduce pests and diseases.
2. Use fertilizer scientifically to ensure demand. Fruits and vegetables need more fertilizer and faster fat consumption. Therefore, it is necessary to apply enough base fertilizer to ensure the supply, especially in the seedling stage, flowering stage, mature stage and the first harvest of fruits, and they must be top-dressed. The combined application of nitrogen, phosphorus, potassium and trace elements (boron, calcium, zinc, 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 stages of vegetable growth, extra-root fertilizer can also be applied.
3. Irrigation cooling, dissolved fertilizer promote long. During the high temperature season, furrow irrigation or sprinkler irrigation should be performed in time according to soil conditions and melon vegetable production dynamics, 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, supplement water and dissolve fertilizers, and facilitate root absorption. On the other hand, timely cultivating in the rain, breaking the knot, and maintaining the oxygen increase health promotion.
4. Take heart at a proper time to promote precociousness. 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 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 and grow robustly. Common diseases of vegetables in high temperature season include viral diseases, anthrax, gray mold, ulceration disease, insect pests such as aphids, red spider, tobacco budworm and cotton bollworm. Because vegetables and fruits are people's daily foods, they should be especially careful when using drugs. They must not 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 harvest.
6. Harvest in time, mention the morning market. Harvesting vegetables and fruits at the right time can yield high yields and increase economic benefits. Like most fruits can be harvested at eight mature, eggplant, beans should be harvested when nine mature as well.
