Abstract

The invention relates to an irrigation method of controlling the low-limit soil water in main growing period of wheat. The principle is as follows: according to water demanding rules formed by the high-yield and high-quality coordination of wheat, the water content of soil to be irrigated is determined by the growing season and serves as an irrigation indicator, so that the soil water supply is consistent with the water demand formed by the high yield of wheat.

Description

One grow wheat primary growth stage controls the irrigation method of soil lower bound moisture

Technical field

The invention belongs to agricultural technology field, for improving yield of wheat water-saving irrigation, be specifically related to the irrigation method that a grow wheat primary growth stage controls soil lower bound moisture.

Background technology

Irrigation is the important cultivation management technology of Wheat Production the next item up.There is multiple Irrigation in current production.According to the number of wheat irrigation frequency in life, Irrigation can be divided into: 5 aqueous modes (time of infertility filled with 5 water by wheat): pour water before surviving the winter, period of seedling establishment is poured water, the shooting stage pours water, booting stage pours water, irrigation at seed filling stage; 4 aqueous modes (wheat growth stage fills with 4 water): pour water before surviving the winter, the shooting stage pours water, booting stage pours water, irrigation at seed filling stage; 3 aqueous modes (wheat growth stage fills with 3 water): pour water before surviving the winter, the shooting stage pours water, booting stage pours water; 2 aqueous modes (wheat growth stage fills with 2 water): pour water before surviving the winter, booting stage pours water; 1 aqueous mode (wheat growth stage fills with 1 water): pour water before surviving the winter, or booting stage pours water, or the shooting stage pours water, or pour water flowering stage (Wang Guangxing etc., 1990; Wang Xu etc., 2012; Dong is superfine, and 2012; Liu Li equality, 2012).Fill with the method for 1 ~ 3 water at wheat growth stage, be referred to as wheat water-saving irrigation, or control irrigation or Limited Irrigation, or deficit irrigation (Wang Guangxing etc., 1990; Zhou Jihua etc., 2008; Hu Xiangming etc., 2010; Tan Niantong etc., 2011; McCarthy et al., 2013; Pang et al., 2013).

The shortcoming of existing Irrigation: no matter which kind of Irrigation is all irrigate by rule of thumb or according to soil mode of appearance, lack the accurate quantification index of irrigating, and the type of soil is different, the mode of appearance of soil differs greatly; Irrigate according to soil mode of appearance, be difficult to precision, the quantification of accomplishing to irrigate, being difficult to realize soil water supply needs the consistent of water with wheat plant, is difficult to the requirement reaching high yield, efficient water use.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a grow wheat primary growth stage by controlling the irrigation method of lower bound soil moisture.

The present invention is the irrigation method of a kind of collaborative raising output and water use efficiency, its principle coordinates the law of needing the water of formation, divide the soil moisture content of determining breeding time to need to irrigate, and in this, as the index of irrigating, make soil moisture supply consistent with the water demand that improving yield of wheat is formed.
