How to manage high temperature balsam pear in summer? Please introduce the management method of balsam pear root system like wetting, avoid stagnant water, usually should pay attention to dig drainage ditch, in case of rainstorm, should timely eliminate stagnant water in the field. The use of water can be carried out according to the dry and wet condition of the soil. In general, in sunny days, the sun is fierce, evaporation is large, and water disappears quickly, so it is necessary to sprinkle water in time to ensure its physiological water requirements, avoid drought and wilt, and affect plant growth and development, flowering and fruiting. In the period of high yield, sufficient nitrogen, phosphorus and potassium fertilizers were supplemented with water. The simple way is to sprinkle various fertilizers on the inner surface of the balsam pear field. You can also use fully mature farm manure. Pay attention to the principle of "small amount of diligent application" in the amount of fertilizer. Balsam pear to enter the peak period of fertilization should be adequate, high temperature and drought season should be timely watering, the box is best covered with wheat straw to moisturize, and pay attention to prevent stagnant water. First, weeding: balsam pear field open land, surrounding ridges, ditches are not allowed to have grass, can be killed with glyphosate drugs. Plant finishing: remove the old, yellow and diseased leaves in the lower part of the shed in time, as well as the melon-free branches hanging to the lower part. If possible, branches without melons or female flowers in the upper part should also be removed. If you are sick, the insects should be removed in time. All picked leaves, branches and fruits should be bagged and destroyed. Second, flower promotion is often sprayed with a small amount of "flowering essence", "Chuoguoling", "spraying treasure", "amino acid", aloin, borax, phosphorus dimethyl, calcium nitrate and so on. Third, the harvest of balsam pear should be harvested in time, when the young melons grow fully. The pericarp is protruding and swollen, and the top of the fruit is harvested when it begins to shine. Fourth, prevention and control of balsam pear are often caused by nematode disease, Fusarium wilt (grafted seedlings are generally not affected), powdery mildew, blight and so on. The main pests are melon fruit flies and aphids. Powdery mildew: the disease occurs during flowering and fruiting, and the leaves are covered with white powdery matter, making the leaves green and yellowing, resulting in premature senescence of the plant. Prevention and control methods: when there is a white powder on the leaves, the aqueous solution of sulfur suspending agent should be sprayed every 10 days for prevention and control, and the amount of water must be large. Epidemic disease: on the leaves, it starts from the leaf tip or leaf edge, the shape of the disease spot is irregular, the periphery is not obvious, the initial dark green, water stains, and then turn brown. The disease spot can expand to the whole or more than half of the leaves, and when it is wet, a circle of white mildew grows at the junction of the disease spot. Control agents: chlorothalonil, Bengke, Bordeaux liquid, Nongliling, Anke, Sixion morpholine, ethyl phosphate aluminum, disinfectant alum or Jinreidi spray, diseased leaves removed and taken away for destruction. Borer: triazophos, Shachongdan, Shachongshuang, Regent, chlorpyrifos spray. Aphids: imidacloprid, acetamiprid, avermectin spray. Melon fruit fly: take the larva to eat into the young melon as a harm, make the young melon deformed, and change color ahead of time, then rot and deteriorate, but also emit a foul smell. Control method: in the young melon stage, spray the young melon with Regent water solution, or farmland happy water solution, or kung fu water solution for 3 times, once every 5 days, and remove the deformed fruit in time, burn it or bury it deeply outside the garden.
