Embodiment 1

[0022] The test was carried out at the test base in Mudan District, Heze City, Shandong Province from 2018 to 2019. The test site is located in the middle of the winter wheat planting area in Southwest Shandong Province, which belongs to the temperate continental monsoon climate zone, which is mainly characterized by hot summer and cold winter and four distinct seasons. There is drought and little rain in spring, concentrated rainfall in summer, gradually decreasing rainfall in autumn, and less rain and snow in winter. The annual average temperature is 14.2 ℃, the average annual precipitation is 593.6 mm, and the annual sunshine time is 2298.8 h. The soil texture of the test site was loam. The width of the test plot is 2.0m, the length of the furrow is 40m, and the area is 80m 2 , the irrigation water source of the experimental field is an agricultural well, and the "Xiaobailong" hose is used to transport water from the water source to the border field. The wheat variety use...

Abstract

The invention discloses a water-saving and stable-yield irrigation method of winter wheat. According to different moisture requirements of the winter wheat in different stages of the whole growth period, comprehensive measures, such as straw mulching for soil moisture conservation, water-saving fertilization, reasonable tillage, seedling control with water and precise irrigation, are adopted; theirrigation time and the irrigation quota in each growth period are determined; moisture requirements of the winter wheat in a critical growth stage are satisfied; furthermore, wheat population development can be controlled through soil moisture management; a high-yield, stable-yield and anti-lodging population structure is formed; the irrigation water utilization efficiency and benefits are increased; and double purposes of the winter wheat including water saving and stable yield can be realized. The water-saving and stable-yield irrigation method of winter wheat in the invention is simple andconvenient to operate and affordable, and suitable for being popularized and used in an area with limited irrigation due to water shortage.

Description

technical field [0001] The invention belongs to the technical field of winter wheat planting, and in particular relates to a water-saving and stable-yield irrigation method for winter wheat. Background technique [0002] Agriculture is a major water user in our country. Taking Heze City in Southwest Shandong as an example, the water consumption for farmland irrigation accounts for about 80% of the city's total water consumption. Winter wheat is one of the main crops in southwestern Shandong, and its sown area accounts for more than 75% of the total cultivated land area. Because of its large water demand and the main growth period is the dry season with less precipitation in the northern region, wheat has become the main crop that consumes irrigation water in this region. And Southwest Shandong is a resource-based water-shortage area, and the available irrigation water per mu is only equivalent to 70% of the agricultural irrigation quota (50% guarantee rate) standard promul...
