Green high-yield package fertilizer suitable for drip irrigation of cotton in southern Xinjiang region and fertilization method

Abstract

The invention provides a green high-yield package fertilizer suitable for drip irrigation cotton in southern Xinjiang region, which designs a full-growth-period fertilization scheme on the basis of medium-fertility soil nutrients, and comprises the following effective elements in percentage by weight based on pure nutrients: 21-23% of N, 10-12% of P2O5, 7-9% of K2O, wherein the controlled-release N accounts for 45-55% of the total N, the nutrient release period of the controlled-release N is 6090 days, the controlled-release N is divided into a base fertilizer, a drip irrigation fertilizer and a foliar water-soluble fertilizer to form a package fertilizer, and the sustained-release compound fertilizer is used as the base fertilizer. Through plot tests and field demonstration for many years, various technologies are integrated, a cotton green, light, simple and efficient fertilization technology mainly which comprises slow and controlled release compound fertilizer base application, drip irrigation fertilizer dressing and foliar water-soluble fertilizer application is integrated, and the fertilization mode can effectively reduce the use amount of chemical fertilizer, increase the yield of cotton and improve the utilization rate of the fertilizer and cotton planting benefits.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a green high-yield package fertilizer suitable for drip irrigation of cotton in the southern Xinjiang region and a fertilization method. Background technique [0002] Cotton is an important economic crop and occupies an important position in my country's national economy. The current increase in cotton production is mainly based on the high input and high consumption of agricultural resources, the excessive use of chemical fertilizers, the low utilization rate of fertilizers, and serious environmental pollution. This project aims at the excessive amount of fertilization in drip irrigation and fertilization in southern Xinjiang (Bazhou area), high price of drip irrigation fertilizer, single formula, easy precipitation and clogging of drippers between drip irrigation fertilizer nutrients, uneven fertilizer and water, trace elements and biostimulants The low efficiency of ferti...

AI Technical Summary

Problems solved by technology

Conventional fertilizers and fertilization techniques for cotton production have the following major technical problems: First, there are many times of fertilization, many labors, and complicated topdressing procedures; second, it is difficult to master fertilization techniques, such as blindly excessive fertilization, unreasonable fertilization methods and periods, and low fertilizer efficiency. , heavy pollution

Drip irrigation and fertilization in Xinjiang also has problems such as excessive fertilization, high price of drip irrigation fertilizer, single formula, easy sedimentation and clogging of drippers between drip irrigation fertilizers, resulting in uneven fertilizer and water, and low efficiency of drip irrigation and fertilization of trace elements and biostimulant fertilizers.
