Problems solved by technology

[0003] Disadvantages of existing irrigation modes: No matter what irrigation mode is used, irrigation is performed based on experience or based on the appearance of the soil, and there is a lack of precise quantitative indicators for irrigation, and the appearance of the soil varies greatly depending on the type of soil; It is difficult to achieve precise and quantitative irrigation, to achieve the consistency of soil water supply and water demand of wheat plants, and to meet the requirements of high yield and efficient water use

Embodiment 1

[0022] In 2011-2012, the "Wheat Irrigation Method for Controlling Low Limit Soil Moisture" (referred to as the new irrigation method) experiment was carried out in Yangzhou and Lianyungang, Jiangsu, respectively, with the local wheat customary irrigation method as the control. The local high-yielding wheat varieties were used in the test site. The varieties in Yangzhou test site were Yangmai 16 and Yangmai 20, and the varieties in Lianyungang test site were Lianmai 6 and Huai Mai 23. Except for the different irrigation methods, the new irrigation method and the control were completely consistent in other cultivation measures, such as sowing date and method, fertilization period and amount, and pest control.

[0023] New irrigation method:

[0024] 1. Before wintering (tillering period before winter)

[0025] (1) Clay: 0-15cm plow layer soil moisture content ≤ 47%, irrigation 40mm (equivalent to irrigation water 400m 3 per hectare); 0-15cm plow layer soil moisture content > 4...

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

technical field [0001] The invention belongs to the technical field of agriculture and is used for high-yield and water-saving irrigation of wheat, in particular to an irrigation method for controlling the lower limit moisture of soil during the main growth period of wheat. Background technique [0002] Irrigation is an important cultivation management technique in wheat production. At present, there are many irrigation modes in production. According to the number of times of irrigation in the life of wheat, the irrigation mode can be divided into: 5-water mode (5 times of water during the whole growth period of wheat): irrigation before wintering, irrigation at the greening stage, irrigation at jointing stage, irrigation at the booting stage, and irrigation at the filling stage; 4 Water mode (watering 4 times during wheat growth period): watering before overwintering, watering at jointing stage, watering at booting stage, irrigation at filling stage; 3-water mode (watering...
