Embodiment

[0021] The embodiments of the present invention provide a safe and high-yield irrigation method for winter wheat in a well-canal combined irrigation area. The method includes using a fixed irrigation method to irrigate with groundwater during the winter wheat turning green period, irrigate with surface water during the jointing period of the winter wheat, and irrigate with the surface water during the winter wheat grouting period. surface water for irrigation;

[0022] Wherein, the volume percentage of the surface water consumption in the total irrigation water is not less than 67%.

[0023] Further, the groundwater is well water, and the surface water is canal water. The well water and the canal water are free of cationic surfactants, sulfides, cadmium, total arsenic, chromium, lead, copper, zinc, roundworm eggs.

[0024] Further, the irrigation quota of the quota irrigation method is determined according to the soil texture structure. Described soil texture is silty clay s...

Abstract

The invention discloses a safe and high-yield irrigation method for winter wheat in a well-canal combined irrigation area. The method comprises the steps of respectively adopting underground water forirrigation in a green-returning period of the winter wheat in a quota irrigation mode, adopting surface water for irrigation in the jointing period of the winter wheat and adopting surface water forirrigation in the grouting period of the winter wheat. The surface water consumption is not less than 67% by volume of the total irrigation water. The method provided by the invention is suitable forwell and canal combined irrigation in areas with insufficient surface water, safe and efficient irrigation in areas with insufficient surface water can be realized through the method, The high yield of the winter wheat and the good quality of the obtained winter wheat can be guaranteed, and meanwhile, through the determination of well water, canal water irrigation time and irrigation quota, soil salinization can be effectively prevented. The method is worthy of extensive application.

Description

technical field [0001] The invention relates to the technical field of irrigation methods, in particular to a safe and high-yield irrigation method for winter wheat in a well-canal combined irrigation area. Background technique [0002] According to the regional layout in the National Agricultural Sustainable Development Plan (2015-2030), the Huanghuaihai Plain is one of the important agricultural optimization development areas in my country, but its resources and environment do not meet the requirements of the development plan. The available freshwater resources in this region are in short supply, and agricultural water is particularly tight, with a supply-demand gap of over 10 billion m2 3 , a large amount of salt water resources in shallow underground layers are important available resources for agricultural production. Soil salinization in the Huang-Huai-Hai Plain has a long history. Although it has been improved to a certain extent after years of improvement, its poten...
