Detailed Explanation of Field Management Techniques for Cotton at the Squaring Stage

In order to build a good framework for high cotton yields, based on the growth characteristics of cotton at the squaring stage, and in view of the production situation this year with more late-planted cotton and uneven growth, the following field management technical measures are hereby proposed:

1. Clarify the guiding ideology and main objectives. Guiding ideology: seize the timing and strengthen science and technology, reduce humidity and increase temperature to promote root development, improve nutrition and adjust plant architecture, build up plant health and vigor in pursuit of balance. Main objectives: vigorous plant development with steady growth, strong plants with increased squares.

2. Highlight field management priorities and strictly control technical keys.

1. Complete the finishing work of deep intertillage and high ridging, and treat it as an important field management measure at present; in terms of method, focus on promoting ox-plow intertillage and ridging.

2. Focus on deep placement of large-hole fertilizer as the center, comprehensively improve the nutritional status, and use large-hole fertilizer to promote the full completion of intertillage and ridging.

① Timing must be early. The whole county must ensure that large-hole fertilizer application is fully completed before June 20;

② Highlight the "three emphases." Emphasize phosphate fertilizer, potassium fertilizer, and organic fertilizer;

③ Scientific matching and formula fertilization. For early-planted, early-developing cotton, apply 5 jin of urea fertilizer per mu; for individual plants with vigorous growth, do not apply urea fertilizer; for late-planted cotton after wheat, apply 8-10 jin of urea fertilizer per mu; if urea fertilizer has already been used to promote seedlings after transplanting, do not apply urea fertilizer again. Phosphate fertilizer 70-80 jin per mu, ternary compound fertilizer 30-50 jin per mu
