Both the vegetative growth and reproductive growth of cotton reach their peaks, and nutrient demand is greatest. Timely fertilizer supplementation plays a key role in promoting cotton bolls, preventing premature senescence, setting more bolls on all three fruiting branches, and increasing boll weight. In fertilization, the cotton plants should be kept from excessive vegetative growth. For cotton fields with high fertility and vigorous plant growth, topdressing can be delayed until the full flowering stage when 1 to 2 large bolls have formed on the lower part of the plant; for cotton fields with low fertility and weak growth, flower and boll fertilizer should be applied early and heavily at the initial flowering stage. Generally, in mid-to-late July, apply urea per mu
