Last Updated: 2024/11/06, The symptoms of boron deficiency can appear after the emergence of boron-deficient cotton seedlings, such as thickening and darkening of cotyledons, easy folding of young buds, wilting and drooping in the shape of "GE" (normal leaves on the top of the leaves, showing a "Y" shape); the development of terminal buds stagnated and did not produce true leaves in serious cases, resulting in the death of seedlings. Lack of boron at seedling stage, due to terminal bud growth.

The purpose of chemical fertilizer is to supply cotton nutrients, and in addition to providing nutrients to cotton, the application of microbial fertilizer is important to increase the beneficial microflora of the soil in the root layer, improve the soil microflora and improve the aggregate structure. adjust the soil physical, biological and chemical properties to the optimal proportion, so as to improve soil fertility. The application of microbial fertilizer to cotton is divided into seedling fertilizer, base fertilizer and topdressing fertilizer. When using the cotton seedling transplanting method to prepare the seedling nutrient soil, 5 kg of bio-organic fertilizer can be added to every cubic meter of nutrient soil, which is beneficial to prevent disease and strengthen seedlings. Base fertilizer in cotton fields with certain fertilizer conservation capacity, 50 kg of bio-organic fertilizer per mu is used as base fertilizer. Topdressing cotton at flower and boll stage with black plus white biological fertilizer 20Mu 25kg topdressing. The cotton fields with poor soil fertility and sandy texture should increase the amount of fertilizer application. In addition, in the middle and later stage of cotton growth, 1 kg of microbial agent per mu, 20 kg of water, stirring evenly and standing for 1 hour, and the supernatant combined with foliar spraying of zinc and boron fertilizer can promote cotton plant growth and enhance cotton plant resistance. reduce the occurrence and harm of Verticillium wilt.
