First, scientific fertilization, to ensure that the need for melons and vegetables is a crop that requires a large amount of fertilizer and fast consumption, so it is necessary to apply sufficient fertilizer to ensure the supply of fertilizer. Especially in the seedling stage, flowering stage, maturity stage and the first batch of fruit harvesting, it is necessary to topdress in batches. A combination of nitrogen, phosphorus, potassium, etc. is applied.
Second, irrigation and cooling, fertilizer promotion in the high temperature season, should be based on soil conditions and production status of melons, timely irrigation or sprinkler irrigation, in order to reduce ground temperature, temperature and leaf temperature, reduce the high temperature burning encountered; Dissolving the fertilizer is beneficial to the absorption and utilization of the fertilizer by the root system.
Third, timely picking the heart, promote early harvest of pepper, eggplant, tomato, etc. After harvesting the first loquat fruit, the top and side hearts should be removed according to the cultivation density. Eliminate the "top advantage" and promote the balanced growth of the plants, that is, the top and the heart can be beaten when the line is closed; when the line is not closed, only the top of the heart is not beaten. Cucumbers, melons, watermelons, etc., when the melons grow to about 25 leaves, they can be topped and the middle and upper branches and axillary buds can be removed, so that the nutrients can be transported to the young fruit in a concentrated manner, which promotes rapid expansion.
Fourth, the prevention and control of pests and diseases, strong growth of summer and autumn vegetables common pests and diseases are mainly anthracnose, gray mold, ulcer disease and aphids, red spiders, tobacco budworms, cotton bollworm and so on. Because melons and vegetables are indispensable foods for people, they should be especially careful when using drugs to avoid the use of high-toxic and long-lasting pesticides to ensure the safety of humans and animals. Whether it is treating insects or treating diseases, pesticides should not be used for 10 days to 15 days before harvesting.
