How to fertilize cotton for high yields? Scientific fertilization methods shared

In cotton cultivation, it is common that plenty of fertilizer is applied, yet cotton yields decline instead. This is because farmers do not understand the fertilizer requirements of cotton and fertilize irrationally, which not only wastes fertilizer but also causes low cotton yields and poor quality. Cotton farmers should grasp the following key points in fertilization:

1. Choose the right fertilizer types: on the basis of applying nitrogen fertilizer well, increase the amount of phosphorus and potassium fertilizer to enhance cotton's disease resistance, prevent premature aging in the late stage, and increase cotton yields.

2. Determine a reasonable fertilization amount: it is best to combine this with soil testing and formula fertilization technology, follow the fertilization recommendations of technicians, and fertilize scientifically and reasonably.

3. Grasp the cotton fertilization periods: cotton farmers should understand the fertilizer requirements of cotton and apply the seedling promotion fertilizer, bud stage fertilizer, flowering and boll fertilizer, and late-stage foliar spray fertilizer in separate applications.

4. Master the correct fertilization methods: during fertilization, the burying method should be adopted to improve fertilizer use efficiency, avoid being too close to the roots, and strictly prevent fertilizer burning of roots or mechanical root damage, which can cause premature aging and death of cotton and affect yields.

5. Pay attention to spraying micronutrient fertilizers: in cotton fields lacking boron, zinc, and calcium, trace element fertilizers should be sprayed. At the same time, during the early flowering stage and flowering and boll stage of cotton growth, Tianfengsu can be sprayed to reduce the shedding of cotton buds and bolls and increase cotton yields.
