Embodiment 2

[0042] Example 2: Illustrate the experiment and mathematical fitting process of the relationship between the water consumption during the whole growth period of the crop and the wheat yield S in the present invention. The experimental site was artificially ridged, and the section of the furrow adopts a trapezoidal form. The specifications of the trapezoidal furrow and furrow are respectively 70cm and 40cm, the height of the ridge is 20cm, and the distance between the centers of two adjacent furrows is 110cm.

[0043] The irrigation scheme of winter wheat in this experiment is shown in Table 1; the yield component factors of winter wheat are shown in Table 2; and the water use efficiency of winter wheat is shown in Table 3.

Abstract

The invention provides a winter wheat annual ridge culture and furrow irrigation yield prediction method and irrigation quality assessment method. By obtaining the influence factors such as the annual average temperature T, the multi-year average precipitation R, the average hours of sunshine H, the frost-free season T0, and the water consumption during the whole growth period of crops through measurement, the wheat predicted yield S and the irrigation quality assessment value Index are obtained. Through experiments and mathematical calculations, yield prediction and irrigation quality assessment for winter wheat annual ridge culture and furrow irrigation are realized, so that the agricultural water using efficiency is increased, the irrigation water is saved, the yield is increased and the objectives of agricultural efficiency increase and farmer income increase are achieved.

Description

Technical field [0001] The invention relates to agricultural planting and farmland irrigation, and is a new type of planting and irrigation evaluation method, belonging to the field of agricultural engineering. Background technique [0002] In order to alleviate the water shortage in the arid and semi-arid areas of North China, accelerate the pace of water saving in farmland, promote the development of high-efficiency agriculture and modern agriculture in irrigation areas, and comprehensively promote the construction of a water-saving society. It is necessary to actively change the farming system, search for effective water-saving irrigation methods, and promote drought-resistant and water-saving technologies on a large scale. This is not only to effectively increase the utilization rate of agricultural irrigation water, to achieve the actual needs of agricultural water saving, but also to guide farmers to change their irrigation concepts and reduce water waste. , The inevitable ...
