Qinggou drainage, irrigation and cooling in summer and rainy, should often clear the field furrows to eliminate waterlogging, improve the living environment of vegetable rhizosphere, reduce pests and diseases, to avoid the occurrence of roots. During the high temperature season, furrow irrigation or sprinkler irrigation should be carried out in time according to the soil moisture conditions and growth potential of vegetables, in order to reduce the soil temperature, air temperature and leaf temperature, and reduce the high temperature and hot air encountered by the blades.
Scientific use of fertilizers, timely picking vegetables, fruits and vegetables need fertilizer, fertilizer consumption is fast, should be enough base fertilizer to ensure the supply, especially in the seedling stage, flowering period, maturity and fruit after the first harvest, to be top-dressing. The combination of nitrogen, phosphorus, potassium and trace elements (boron, calcium, zinc, iron) can achieve good effects on plant regeneration, increase of second crop yield, and prevention of premature senescence. In the middle and late stages, extra-root fertilizers can also be produced. Pepper, eggplant, tomato, etc., after harvesting the first loquat fruit, should be based on the density of timely removal of the top heart and side of the heart, eliminating the "top dominance" and promote balanced growth of the plant. 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.
