How should cotton be managed in the middle and later stages of planting? Please give guidance on cotton management methods in the middle and later period, you can refer to the following methods: first, pruning management. For the luxuriant branches and leaves that have covered the whole cotton field, the old leaves, yellow leaves and empty branches without buds in the lower part of the main stem can be removed to achieve the effect of light transmission, which can not only make the leaves better absorb sunlight, but also disperse moisture and reduce the occurrence of Verticillium wilt. Second, apply superfluous buds at the right time. The superfluous bud mainly grows at the junction of the fruit branch and the main stem, will not form cotton peach, but will consume a lot of nutrients, resulting in insufficient nutrition and shedding of the bud, so it should be erased at any time. Not all the superfluous buds have to be removed, and sometimes the axils of the middle and upper fruit branches can be retained to increase the chances of setting peaches. Third, beat the heart. It is necessary to top timely, which can not only control the height of cotton plants, but also achieve the effect of ventilation and light transmission, so that nutrients can better serve buds and bolls, so as to increase peach rate and boll weight, and help to increase production and income. If topping too early, nutrients will be lost to the upper branches and leaves, resulting in overgrowth, covering the lower leaves and affecting ventilation and light transmission. If the topping is too late, the nutrition supply of autumn peaches will be insufficient, resulting in late ripening and affecting the yield. According to experience, generally speaking, about 2 early autumn peaches are the most suitable time for topping. The management of cotton in the middle and later period has a great effect on the yield of cotton, which should be timely and timely, and at the same time, it should be combined with ploughing and loosening soil to ensure the rate of peach bearing and increase the yield.
