Four key techniques to grasp in the management of cotton during the boll-opening stage
Grasp the "four key techniques" in cotton management during the boll-opening stage (skillfully manage fertilizer and water, skillfully prune, skillfully pick rotten bolls, skillfully promote ripening). 1. Skillfully manage fertilizer and water to promote nutrient transport. First, foliar topdressing. For cotton fields where leaves lose green too early and show premature aging due to nutrient deficiency, spray 50-60 kg per mu of 1%-2% urea solution onto the leaves to extend the functional period of the leaves. For cotton fields that grow too vigorously and show late maturity with excessive vegetative growth, foliar spray 0.2% potassium dihydrogen phosphate solution or 0.3% superphosphate soaking liquid to promote nutrient transport and help improve boll opening. Second, prevent autumn drought.

What are the key management techniques for cotton during the flowering and boll stage?
Cotton enters the flowering stage in early July, and the period from late August to early September when bolls open is the flowering and boll stage. The flowering and boll stage is the period of most vigorous cotton growth and development, and also the key period that determines yield. This year, due to higher temperatures, cotton growth and development has generally been faster, which

Topdressing Methods and Technical Key Points for Cotton During the Flowering and Boll Stage
Cotton fields are currently entering the flowering stage one after another. After this, cotton will enter the flower and boll stage lasting more than 50 days, which is the peak period of fertilizer demand for cotton. During the more than 50 days of the flower and boll stage, cotton continuously flowers and sets bolls, and its demand for nutrients is continuous and uninterrupted. Therefore, except for particularly fertile soil, topdressing is necessary to supplement nutrients. Topdressing during the flower and boll stage is an important task in the management of cotton during the flower and boll stage. 1. For plots short of fertilizer, increase the amount of topdressing. In areas where the per capita cotton planting area is relatively large, some villages still maintain a state of low input and low output

How to carry out field management of cotton during the flowering and boll stage? Technical Q&A
1. What is the flowering and boll stage? The stage from flowering to boll opening, generally from early July to early September. There is a farming saying, "flowers see flowers forty-eight," but in fact in China's Yellow River basin it generally takes 50-70 days. When 10% of the cotton plants in the field have flowered, it is called the initial flowering stage; when 50% have flowered, it is called the flowering stage. When 50% of the cotton plants have the first fruiting node of the fourth fruiting branch flowering, it is called the full flowering stage. 2. What are the management principles during the flowering and boll stage? The initial flowering stage is the transition from vegetative growth to reproductive growth, and management should focus on control, preventing

What are the key field management points for cotton during the flowering and boll-setting stage?
The flowering and boll-setting stage of cotton is the key period for yield formation. In addition to good fertilizer and water management, the following points should also be done well: chemical regulation. Chemical control during the flowering and boll-setting stage can shift more nutrients from vegetative growth to reproductive growth and reduce the shedding of squares and bolls. It is recommended that for cotton fields with strong growth, at the beginning of flowering, spray 2.0-2.5 grams of mepiquat chloride per mu, or 8-10 milliliters of 25% chlormequat. At full flowering, carry out chemical control again according to growth, spraying 2.5-3.0 grams of mepiquat chloride per mu, or 2
