Problems solved by technology

Excessive application of chemical fertilizers, unbalanced nutrient supply, coexistence of high yield and low efficiency and low yield and low efficiency generally exist in the production of major crops, especially: heavy nitrogen and phosphorus fertilizers, light potassium fertilizers; heavy macronutrients, light trace elements; heavy inorganic fertilizers, light The phenomenon of "three heavy and three light" of organic fertilizer
At present, the average yield per mu of soybean in my country is about 100 kilograms. Problems such as improper fertilization period and unreasonable application methods restrict the further improvement of soybean yield level and economic benefits.

Abstract

A cultivation method for increasing the yield of loessal soil soybeans includes the steps of field selection, field preparation, fertilization, variety selection, sowing, later field management, plant disease and insect pest prevention and harvesting. With the combination of fertilization requirement characteristics of the soybeans and according to feeder capability of loessal soil and yield targets, the application quantity of nitrogenous fertilizers, phosphorus fertilizers and potash fertilizers is determined, and crop physiological problems caused by blind fertilization and excessive fertilization are avoided. Nitrogen, phosphorus and potassium combined application is realized, organic fertilizers are combined with inorganic fertilizers, and intertillage and earthing-up are carried out, so that the utilization rate of the fertilizers is increased. The yield of the loessal soil soybeans is effectively increased, and the aims of high yield, cost reduction and efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method for improving soybean yield in loess cotton soil. Background technique [0002] The technology of soil testing and formula fertilization has been widely promoted and applied in recent years. This technology is based on soil testing and fertilizer field experiments, according to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, and on the basis of rational application of organic fertilizers. And solve the contradiction between the fertilizer needs of crops and the fertilizer supply of soil, and at the same time supplement the nutrients needed by crops in a targeted manner, achieve a balanced supply of various nutrients, meet the needs of crops, and achieve the purpose of improving fertilizer utilization efficiency. [0003] Soybeans are rich in a variety of nutrients and are produced in Northeast China, Nort...
