Last Updated: 2024/11/05, Why should cotton be fertilized with flowers and bolls? Please introduce the reason why cotton flowering is not only a period of rapid growth of vegetative organs such as stems, branches and leaves of cotton plants, but also a key period for a large number of flowering and bolls to form yield. During this period, cotton plants accumulated the most dry matter, the demand for nutrients increased greatly, and there were a lot of nutrients in the leaves.

Why should cotton be fertilized with flowers and bolls? Please introduce the reason why cotton flowering is not only a period of rapid growth of vegetative organs such as stems, branches and leaves of cotton plants, but also a key period for a large number of flowering and bolls to form yield. During this period, cotton plants accumulated the most dry matter, the demand for nutrients increased greatly, and a large number of nutrients in leaves were consumed, so there was an urgent need to supplement nutrients. At this time, the content of available nitrogen in the soil decreased sharply, so it is necessary to re-apply flower and boll fertilizer to supplement the lack of soil nutrients and meet the nutrient needs of cotton plants. Through the re-application of flower and boll fertilizer and making use of the favorable conditions of high temperature and sufficient light in this period, cotton plants can be promoted to bloom and set bolls, so as to create a good material basis for early maturity, high yield and high quality of cotton. The flower and boll fertilizer should be mainly available nitrogen fertilizer in order to exert the fertilizer effect quickly. The amount of topdressing is generally 1520 kg of standard nitrogen fertilizer per mu, accounting for more than 1/2 of the total topdressing amount. The method of fertilization requires deep application of ditches and "promoting fertilizer with water" in case of drought to improve fertilizer efficiency.
