How to manage cotton during the flowering and boll-setting stage? Apply flowering and boll fertilizer heavily, use chemical regulation and pruning to prevent premature senescence
The flowering and boll-setting stage of cotton is the peak period of fertilizer and water demand and the critical period for yield formation. This article introduces the topdressing rate of flowering and boll fertilizer, the standards for irrigation and drainage, the dosage of mepiquat chloride for chemical regulation, the timing of pruning and topping, and pest and disease control techniques, to help cotton growers set more bolls and prevent premature senescence and boll rot.

Cotton chemical regulation has its finer points: master these technical essentials
In recent years, with the widespread popularization and application of insect-resistant cotton, plastic film mulching and chemical regulation technology, cotton farmers have shown some undesirable cultivation tendencies in cotton cultivation techniques, especially in chemical regulation technology (hereinafter referred to as chemical regulation). Failure to pay attention to timely and appropriately timed chemical regulation leads to excessive vegetative growth and rank growth in cotton fields, over-vigorous vegetative growth, and relatively serious shedding of squares, flowers and bolls, ultimately causing cotton plants to become tall, large and empty, with severe lodging when hit by wind and rain later on, resulting in relatively large losses. During chemical regulation, the goal should be to steadily build a high-yielding framework and increase squares and preserve bolls, mastering the
