Clear the ditch and drain the water, reduce the water level and rain in summer. It is necessary to frequently dredge the field ditch to eliminate the water damage, improve the living environment of the vegetable rhizosphere, reduce the pests and diseases, and avoid the occurrence of retting.

Use fertilizer scientifically to ensure that fruits, vegetables and vegetables require a lot of fertilizer and consume fertilizer quickly, so it is necessary to apply foot fertilizer to ensure the supply, especially in the seedling stage, flowering stage, maturity stage and after the first batch of fruits are harvested. , To achieve the combined application of nitrogen, phosphorus, potassium and trace elements (boron, calcium, zinc, iron), to restore plant vitality, increase the yield of the second batch of fruits, and prevent premature aging, have a good effect. In the middle and later stages, extra-root topdressing can also be carried out.

Irrigate water to cool down and dissolve fertilizer to promote growth. In high temperature seasons, furrow or sprinkler irrigation should be carried out in time according to soil moisture and melon and vegetable production to reduce soil temperature, air temperature and leaf temperature, and reduce the high temperature and heat encountered by leaves. At the same time, it replenishes water and dissolves fertilizer, which is beneficial to root absorption. On the other hand, it is necessary to cultivate in time after the rain, to break the compaction, to preserve moisture, increase oxygen and promote growth.

Timely topping to promote early-maturing peppers, eggplants, tomatoes, etc. After the first fruit is harvested, the top and side cores should be removed at the right time according to the density to eliminate the "top advantage" and promote the balanced growth of the plant, that is, it can be removed when the line is closed The top mind and the side mind, when the line is not closed, only the top mind and not the side mind. For cucumber, melon, watermelon, etc., when the melon vine grows to about 25 leaves, it can be topped and cut off the branches and sprouts in the middle and upper part, so that the nutrients are concentrated to the young fruit to promote its rapid expansion. Beans should be topped flexibly according to the characteristics of the variety and the height of the support. For long vine species, you can topple the core when the vine grows to about 2 meters, while short vine species and autumn beans are not topped. When topping, remove diseased leaves and dead leaves out of the field to reduce the breeding of pests.

Prevention and control of pests and healthy growth of summer vegetables. Common pests and diseases include virus disease, anthracnose, gray mold, fester, aphids, spider mites, tobacco budworm, cotton bollworm, etc. Special care must be taken in the prevention and treatment of pesticides. Highly toxic pesticides with long residual effects are strictly prohibited to ensure the safety of humans and animals. Regardless of the treatment of insects or diseases, the pesticides should not be sprayed 10-15 days before harvest.

Timely harvest, early harvest at the right time in the market can not only produce high yields, but also increase economic benefits. Like most melons and fruits can be harvested at eight ripening, solanum fruits and carob vegetables are better harvested at nine ripening.

Beta carotene is the molecule that gives carrots their orange colour. It is part of a family of chemicals called the carotenoids, which are found in many fruit and vegetables, as well as some animal products such as egg yolks. Biologically, beta carotene is most important as the precursor of vitamin A. It also has anti-oxidant properties and may help in preventing cancer and other diseases.

Beta Carotene is also known as a provitamin because it can be converted in our body into vitamin A after oxidative cleavage by beta carotene 15, 150-dioxygenase. In plants, beta carotene, acts as an anti-oxidant and neutralizes singlet oxygen radicals formed during photosynthesis.
