Winter wheat recommended fertilization method

Abstract

The invention discloses a winter wheat recommended fertilization method and relates to the technical field of crop fertilization. The method includes the steps that after summer crops are harvested, soil is deeply ploughed or deeply scarified, chicken manure, cow dung and human feces are mashed and mixed to be uniform, the mixture is scattered to the earth surface, and the soil is subjected to rotary tillage and soil preparation; winter wheat seeds are dressed with bactericide or / and insecticide; 3-5 days after rotary tillage and soil preparation, the soil is irrigated before sowing is carried out; 2-3 days after irrigation before sowing is carried out, the soil is subjected to sowing, fertilization and rotary tillage integrated operation; on the last ten days of December, the soil is subjected to warming irrigation; 2-3 days after warming irrigation, straw smashed segments are laid on the earth surface; at the elongation stage of winter wheat, the soil is topdressed, and mepiquat chloride, gibberellins and plant cell cytokinin are sprayed. According to the method, the earth temperature is increased through winter irrigation and laying of the straw smashed segments, water and fertilizer are retained, it is avoided that the wheat is subjected to frost bites and frost damage, so that the normal growth period of the wheat is affected, and the yield of the wheat is stably increased.

Description

technical field [0001] The invention relates to the technical field of crop fertilization, in particular to a recommended fertilization method for winter wheat. Background technique [0002] Winter wheat is the main food crop in my country, mainly grown in northern China. The growth period of winter wheat is generally about 240 days. After autumn and winter, spring and early summer, the law of nutrient absorption changes greatly with time, and the cycle of nutrient absorption is long. Therefore, the nutrient management of winter wheat is particularly important, and different growth stages require different nutrient input and management. . [0003] After the deep winter in northern my country, the weather is very cold, and trees and crops need to be treated with antifreeze protection. The conventional methods of wheat cultivation and fertilization do not take into account the need for antifreeze treatment for winter wheat. Under normal circumstances, wheat will not freeze t...
