Problems solved by technology

At present, the layout of ridges and furrows on sloping farmland is mainly considered from the aspects of reducing soil erosion and reducing the pollution of pesticides and fertilizers; it does not systematically consider the process of farmland water cycle and improve the efficiency of precipitation utilization on sloping farmland. Unable to perform quantitative analysis

Embodiment Construction

[0027] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0028] refer to figure 1 , figure 1 Shows a flow chart of the method for the efficient use of rainwater resources for farmland ridge layout on slope farmland; as figure 1 As shown, the method includes the following steps:

[0029] S1. According to the principle of water balance, construct a farmland water cycle model for sloping farmland:

[0030] P=E+In+R+ΔW d

[0031] Among them, P is the net precipitation of sloping...

Abstract

The invention discloses a slope farmland cropland furrow arrangement method aimed at efficient rainwater resource utilization. The method comprises the steps of carrying out frequency arrangement analysis on hour session heavy precipitation in the growing period of slope farmland crops, and adopting session precipitation corresponding to extreme floods as slope farmland cropland net precipitation in the growing period of the slope farmland crops; calculating the actual evapotranspiration of slope farmland croplands; calculating the soil infiltration amount of the slope farmland croplands; calculating the maximum depression retention amount of slope farmland cropland furrows; when the rainfall runoff amount of the slope farmland croplands is zero, calculating the furrow theoretical water storage amount through an established slope farmland cropland water circulation model; and when the furrow theoretical water storage amount is smaller than the maximum depression retention amount of the croplands, optimizing the arrangement parameter of the cropland furrows when the slope farmland furrow distribution number is maximized.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for layout of ridges and furrows on sloping farmland for efficient utilization of rainwater resources. Background technique [0002] More people, less land and less water is the basic national condition of our country. According to the national land use change survey, the national cultivated land area is 1.22×10 4 10,000 hectares, of which sloping farmland accounts for about 1 / 3. Ridges and furrows change the micro-geomorphological characteristics of sloping farmland units, which in turn affect the characteristics of rainstorm runoff on sloping farmland. At present, the layout of ridges and furrows on sloping farmland is mainly considered from the aspects of reducing soil erosion and reducing the pollution of pesticides and fertilizers; it does not systematically consider the process of farmland water cycle and improve the efficiency of precipitation utilization on...
