How to prune cotton boll

The timely pruning of the flower and boll period plays an important role in mediating nutrient distribution, reducing the shedding of bells, improving the ventilation and light conditions of the cotton fields, reducing the number of rotten bells, promoting precocity, and increasing yield and quality.
(1) Hit the top. Cotton topping can break the top edge, regulate the direction of organic nutrient transport, and reduce the number of ineffective branches. The key to the top is to have a good grasp of the time and method of the top. The big top is too early, not only reduces the effective branches and autumn peaches, but also causes the upper fruit branches to grow too long, increases the covertness of the field and the shedding of the bells, promotes axillary buds, consumes nutrients, and manages the work; the topping is too late and does not start. To mediate the role of nutrients, will also increase the upper part of the cotton plant without effective branches and bells, consume nutrients. Appropriate topping time should be based on the growth of cotton, soil strength, density, and local initial frost period. In general, the cotton field in our country can be topped in mid-July, such as fertilization, strong growth of cotton plants, low density, and late frost, which can be postponed until the end of July, but it will not exceed July 25 at the latest; Cotton plants grow weakly, have a high density, and have a frosty period. They can advance to the top in mid-July.
In the method of topping, a lighter top should be used, that is, the top should be removed and a small leaf should be taken. The cotton plants grow neatly at one time, and vice versa.
(2) hit the top. Practice has proved that the conditions for taxation are good, cotton plants grow vigorously, or there is a serious closure trend in the cotton fields, and group leaders can control the time and level of closure of cotton, improve lighting conditions, control ineffective buds, promote early maturation, and reduce rotten bells. Poor water and fertilizer conditions, cotton plants grow weaker or have no tendency to seal the cotton field, can not hit the group tip. Need to hit the top of the cotton field, generally the lower fruit branch can leave 2 to 3 fruit sections, the middle fruit branch to stay 3 to 4 fruit sections, the upper fruit branch as the fruit growth section. Grouping tips should be carried out in phases, usually once before the peak, once after the peak, and at the latest, about 70 days before the initial frost period.
(3) wipe buds, hit the old leaves. Taxes and conditions are good, and cotton plants are growing vigorously or are often topped in cotton fields, and a large number of axillary buds often grow. The axillary buds consume nutrients, affecting the ventilation and light transmission in the field and should be promptly removed. For cotton plants that grow too profusely and the fields are hidden in the cotton fields, in order to improve the conditions for ventilation and light transmission in the fields, and reduce the number of rotten bells and sheds, the old leaves in the middle and lower parts of the main stem can be destroyed in stages.
In addition, the flowering and bolling period is in the high temperature and rainy season, the soil is susceptible to water shortage, reducing the ability of roots to absorb water and fertilizers, affecting the development of the bolls, resulting in the shedding of a large number of budding bells. Therefore, the flowering and bolling period should be timely cultivating loose soil. During the flowering period, the regenerative capacity of the cotton root system is weakened. Therefore, the cultivator should be shallow, usually no more than 6 to 7 centimeters, so as to avoid excessive rooting and premature aging.
