Special liquid package cotton fertilizer for improving soil, and preparation method and application method of liquid package fertilizer

Abstract

The invention relates to a special liquid package cotton fertilizer for improving soil, and a preparation method and application method of the liquid package fertilizer. According to the special liquid package cotton fertilizer for improving soil, the special liquid package fertilizer consists of a composite microbial liquid fertilizer and a macroelement water-soluble fertilizer, wherein the composite microbial liquid fertilizer consists of an amino acid fermentation liquid, fulvic acid, microbial bacteria, a nitration inhibitor and polyaspartic acid, and the macroelement water-soluble fertilizer consists of urea, monoammonium phosphate, potassium chloride, magnesium sulfate heptahydrate, EDDHA-iron, EDDHA-zinc, EDDHA-manganese, EDDHA-copper, boric acid, carboxymethyl cellulose, an amino acid fermentation liquid, bentonite and sodium pyrophosphate. The invention also discloses the preparation method and application method of the package fertilizer. According to the special liquid package cotton fertilizer for improving the soil provide by the invention, the requirements on nutrients in different growth and development periods of cotton can be met, and salinization of soil in Xinjiang can be improved. The application method of the special liquid package fertilizer conforms to the growth characteristics and fertilizer requirement laws of the cotton.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a soil-improving cotton-specific liquid package fertilizer, a preparation method and an application method. Background technique [0002] Xinjiang is located in the northern temperate continental arid climate zone. It is an oasis irrigated agriculture. It has superior natural climate conditions and sufficient light and heat resources. It is especially suitable for cotton production. It is an important high-quality upland cotton and the only long-staple cotton production base in China. Cotton is a pillar industry in Xinjiang, which has a great impact on the economic and social development of Xinjiang. After cotton was introduced to Xinjiang, the traditional planting mode was changed, and a brand-new "short dense early film" drip irrigation planting method was adopted, becoming the largest product base in the country and one of the important "white" industries in Xi...

AI Technical Summary

Problems solved by technology

[0004] At present, Xinjiang mainly uses granular fertilizers. Granular fertilizers will cause blockage if they are insoluble, which will increase the cost of planting, and the utilization rate of fertilizers is also low. Long-term use will also cause certain harm to the environment.

The salinization of land in Xinjiang is relatively serious, and the amount of fertilizer applied by farmers to cultivated land is increasing year by year. If the existing fertilizers are used for a long time, the salinization of the land will be accelerated, and the salinization of the soil will reduce the availability of soil nutrients and cause a series of crop defects. It will also aggravate the compaction of the soil, which will hinder the development of the root system of the crop, reduce the stress resistance of the root system, make the root system of the crop easily infected with root rot and other diseases, affect the growth of the crop, and finally greatly reduce the yield and quality of the crop

And the fertilization method of existing cotton is relatively simple, is unfavorable for the healthy growth of cotton

Although there are similar special fertilizer products on the market, only the title does not have obvious identification, and the formula is confusing, and the effect is not obvious

If you continue to maintain a single fertilization method, it will easily lead to waste of fertilizer, soil salinization, and soil erosion

In addition, cotton is sensitive to potassium, and improper application of fertilizers can easily lead to a decline in cotton yield.
