How to control the crazy growth of cotton in summer? Please introduce the methods to control the excessive growth of cotton in summer. We can refer to the following methods: timely chemical control and spraying metoprolol or prophylaxis can control cotton plant growth, improve plant shape, and produce more buds and bolls. In the early flowering stage, spray Zhuangzhuangsu 6ml / mu or 1.5g / mu with 25kg / mu of water, and spray with 3g / mu / mu with 30kg / mu of water in full bloom (late July and early August). It is generally sprayed after 3 pm or before 10:00 in the morning to prevent the liquid from evaporating with high temperature. Spray in case of heavy rain after spraying, but the dosage should be halved. Controlling the abundance of Rain Water in the rainy season is beneficial to the fertilizer effect and can easily lead to the prosperity and growth of cotton plants. For cotton fields with sufficient base fertilizer and large amount of topdressing at seedling stage, little or no fertilization should be applied, and attention should be paid to ditch drainage and strict prevention of waterlogging. For the cotton fields with slow growth of cotton plants, red stems to the top and small yellow leaves, it is appropriate to apply fertilizer early and increase the amount of fertilizer, about 8 kg of urea per mu. If continuous drought occurs and the soil water content is 60% lower than the field capacity, it should be irrigated at the right time. Wipe the superfluous bud, hit the top of the cotton plant growth is accelerated in the rainy season, superfluous buds are also easy to occur, should take advantage of the rain gap to wipe off the superfluous buds in time. When the cotton plant grows to the predetermined plant shape and has a predetermined number of fruit branches, it breaks or suppresses the apical growth dominance, reduces the nutrient consumption of the upper ineffective branches, and promotes the development of cotton bolls. It usually hits the top in the middle and late July. Click to get more cotton planting technology click to get more food crop planting technology
