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.
Scientific fertilizer guarantee needs
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 combined use of nitrogen, phosphorus, potassium, and trace elements (boron, calcium, zinc, and iron) can have a good effect on plant regeneration, increase of second crop yield, and prevention of premature aging. In the later stage, extra-root fertilizer can also be applied.
Irrigation water cooling 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.
Timing to promote early maturing
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, they can carry out topping and cut off the branches and axillary buds in the upper part, so that the nutrients can be transported to the young fruit to promote 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.
Prevent pests from growing robustly
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 should be especially careful when using drugs to ensure the safety of people and animals.
Timely harvesting
Harvesting fruits and vegetables at the right time can not only produce good yields, but also increase economic efficiency. For example, most fruits can be harvested at the ripening stage. Solanaceous fruits and leguminous species should be harvested at the 9th maturity.
