A kind of green and high-efficiency production method of three sections of water, fertilizer and medicine for winter wheat

Abstract

The invention relates to a winter wheat water fertilizer pesticide three-section green and efficient production method. The method comprises the steps that irrigation water is quantified by moisture measurement supplemental irrigation, the bottom nitrogen fertilizer application amount is determined through the bottom moisture water storage amount, in the elongation stage, the base stalk NO3-N content is measured and the soil moisture content is monitored for determining water fertilizer management in the elongation stage, the nitrogen fertilizer dressing amount in the middle and later stages is quantified, bactericide and insecticide are applied to insect pest and weed management for two-time seed dressing for quantifying the dosage, and therefore effective management of winter wheat water fertilizer pesticide is achieved. The excessive exploitation caused by winter wheat production to underground water under the bi-annular planting condition is lowered, meanwhile, consumption of fertilizer and pesticide is lowered, and green, safe, efficient and sustainable production is achieved; according to the technical scheme, no extra investment is added, the input cost is lowered, and the method has the wide prospect for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of winter wheat planting, and in particular relates to a green and efficient production method of three sections of water and fertilizer for winter wheat. Background technique [0002] Winter wheat needs an appropriate amount of water before planting and during the growth period, and the lack of soil fertility can be supplemented by applying fertilizer. In the wheat planting production technology, the method of supplying water by measuring the soil water demand, there is also the control of the amount of fertilization by measuring the fertilizer content in the soil in different periods and the fertilizer elements required in the corresponding period, but in the prior art, especially in the In areas with severe shortage of groundwater such as the North China Plain, the use of existing irrigation methods and fertilization methods is not conducive to water saving, and the application of fertilizers cannot be co...

AI Technical Summary

Problems solved by technology

[0002] Winter wheat needs an appropriate amount of water supply before planting and during the growth period, and the lack of soil fertility can be supplemented by spreading fertilizers. During the growth period, in order to avoid pests and weeds, it is also necessary to apply medicines for management. The existing In wheat planting production technology, the method of water supply is carried out by measuring the soil water demand, and there is also a method of controlling the amount of fertilizer applied by measuring the fertilizer content in the soil in different periods and the fertilizer elements required in the corresponding period, but in the prior art, especially in In regions with severe groundwater shortages such as the North China Plain, the irrigation methods and fertilization methods of the existing technology are not conducive to water conservation, and the application of fertilizers cannot be completely absorbed by wheat. The combination of elements for green and efficient production
