Second, avoid excessive soil moisture. After the jujube has been planted and cultivated, the management should be based on controlling water and promoting the root. If the soil is not too dry, do not rush to water before the result. Of course, if the plant is short of wilting, it should be poured out of small water to ensure the normal growth of plants, must not flood irrigation, resulting in plant growth. At the same time, the first amount of water of the Zucchini root can not be too large. If it is too large, it will cause the melon to grow, which in turn will lead to plant growth. In order to promote the smooth progress of reproductive growth, water can be poured by pouring small water.
In addition, the late nitrogen control potassium. After the zucchini enters the nectar period, the amount of potash required is large, and therefore the use of high-potassium fertilizers should also be taken into account during rations. Excessive use of high-nitrogen fertilizers should not be used to avoid excessive nitrogen fertilizers and cause plant growth. Of course, if the zucchini is planted too early, if the temperature is too high in the early stage, hormones may be used to regulate it, but it should not be used excessively. In particular, paclobutrazol should not be used repeatedly. Usually in the 5 ~ 7 days after the seedlings of summer squash, 15% paclobutrazol is used to spray the plants 1500 times, but do not spray the growth points, regulate the growth of the plants.
Most of the Fluorine-Containing Phenylamine products are a light yellow oily liquid, relatively high density, insoluble in water. Most of them are used in the manufacturing of pesticides and dye intermediates, small part of them can be used as an analytical reagent. The steam or smoke of fluorine-Containing Phenylamine series is irritated to eyes, mucous membranes and upper respiratory. Vapor and air can form explosive mixtures, in case of fire, high-heat combustion caused the explosion. And oxidant may react. Decomposition by high fever and emit toxic gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion. Protective measures must be done carefully during product storage. Once the fire occurred, it must be immediately evacuated from air leakage,personnel to a safe area, prohibit access to the contaminated area. Recommended emergency personnel wearing self-contained breathing apparatus and wear chemical protective clothing. In the ambulance personnel to ensure proper safety measures, immediately use foam, carbon dioxide, dry, sandy soil to put out a fire.
