Cotton Cultivation Techniques: How to Apply Topdressing During the Flowering and Boll-setting Stage of Cotton?
How to apply topdressing during the flowering and boll-setting stage of cotton? Please provide guidance. During the flowering and boll-setting stage of cotton, the following methods can be referenced for topdressing: 1. For plots lacking fertilizer, increase the topdressing amount. In areas with a relatively large per capita cotton planting area, some villages still maintain a low-input, low-output state, and the cotton planting benefit is very low. Some even apply only 10-15 kg of urea or diammonium phosphate per mu (with an annual seed cotton yield of more than 150 kg per mu). Now the cotton plants have shown severe fertilizer deficiency, especially in Nanpi County, where heavy rainstorms have occurred, cotton fields have accumulated water, and the limited available nutrients in the soil have been leached and lost. Topdressing is urgently needed now.
