A method for preventing and controlling soil erosion in slope land by rotating clover and safflower

Abstract

The invention discloses a method for preventing and treating water and soil losses of sloping fields through crop rotation of burclover and red flowers. The burclover and the red flowers, all of which are high in stress resistance, good in water and soil conservation effect and obvious in economic benefit are finally selected through many times of screening for crop rotation, bio-organic fertilizer serves as a main part in the planting process, the illumination, rainwater, solar terms, planting season time difference and the interdependence relation between plants are sufficiently utilized, a crop rotation crop alternation mode, an interval field emptying mode and other efficient biological modes are adopted, the canopy density of the plants is improved, the water and soil losses are reduced, and losses of nitrogen and phosphorus are controlled and reduced. Meanwhile, the disease, insect pest and weed resistance of the burclover and the red flowers is improved, the yield is increased, and good ecological and economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of water and soil environment protection and crop planting, and in particular relates to a method for preventing and controlling water and soil loss in slope land by rotating clover and safflower. Background technique [0002] Soil erosion leads to the decline of soil fertility and water storage capacity, which is the "source" of agricultural non-point source pollution and water eutrophication. At present, the measures to prevent and control soil erosion on slope land at home and abroad are mainly divided into engineering measures and ecological measures. Engineering measures include building water-blocking ditches, hillside intercepting ditches, slope water storage projects, and terraced fields. Such measures can achieve the purpose of water and soil prevention and control to a certain extent by retaining soil and water storage, but there are problems such as large amount of engineering, time-consuming and ...

AI Technical Summary

Problems solved by technology

Engineering measures include building water-blocking ditches, hillside intercepting ditches, slope water storage projects, and terraced fields. Such measures can achieve the purpose of water and soil prevention and control to a certain extent by retaining soil and water storage, but there are problems such as large amount of engineering, time-consuming and labor-intensive problems. Disadvantages such as unsatisfactory economic and ecological benefits

Ecological measures are divided into soil measures and agricultural measures. Soil measures refer to the application of chemical compounds such as soil improvers and fixatives to the soil to achieve the purpose of improving soil structure, fixing soil, and reducing soil erosion. Such measures to a certain extent It makes up for the time-consuming and labor-intensive shortcomings of engineering measures, but there are also problems such as high labor costs and high ecological risks; agricultural measures are water and soil prevention and control measures implemented on the basis of following the ecological material cycle, including deep plowing, contour plowing, and crop residues. Covering, ridge crop field and hedgerow, etc.
