Karst slope cropland water-saving and soil moisture conservation method and structure

Abstract

The invention discloses a Karst slope cropland water-saving and soil moisture conservation method and structure, and aims to solve the problems that water and soil loss of slope croplands with maximumarea ratio in Guizhou province is severe, soil of the slope croplands is infertile, moisture and fertility preservation effect of the slope croplands is poor, the slope croplands are easily affectedby drought, agricultural implementing cost and agricultural mechanization cost are high and the like. The new scheme includes that by the aid of a compartment surface structure with a downward recessed middle, rainwater can be converged into a ridge compartment recessed surface in raining and permeates a ridge compartment through plant cultivation holes, moisture of the ridge compartment is supplemented, rainwater is converged into furrows and permeates into soil through non-woven fabrics, a large part of moisture can be stored a water conservation side layer of a water storage tile, redundantmoisture can overflow from the water storage tile, permeation and loss are implemented, and water logging of soil caused by excessive moisture can be avoided.

Description

Technical field [0001] The invention relates to the field of agricultural technology, in particular to a method and structure for water-saving and moisture-preserving karst slope farmland. Background technique [0002] Guizhou is a typical karst mountain area, with serious soil erosion and technical difficulties in soil and water conservation. Strengthening of soil and water conservation is the need of Guizhou's agricultural development. [0003] Guizhou is located in the core of East Asia, one of the world's three major karst concentrated areas. The area of ​​karst carbonate is 130,000 square kilometers, accounting for 73% of the province's land area. It is a high mountain area with strong karst development. The mountains and hills of Guizhou account for 92.5% of the total area of ​​the country, and it is the only province in the country without plain support. Due to the special geology, topography, precipitation and other reasons of the Guizhou karst mountainous area, the mounta...

AI Technical Summary

Problems solved by technology

[0006] 2. The biggest weakness of sloping farmland is the easy loss of water and soil, poor moisture retention capacity, and inconvenient agricultural mechanization operations. Solving these problems is the need for the sustainable development of Guizhou agriculture

[0008] At present, there are some drought-resistant and water-saving technologies, but these technologies cannot effectively solve the problems of serious soil erosion, poor soil, and poor water and fertilizer conservation in the slope farmland with the largest proportion in Guizhou. The application effect of these technologies on karst slope farmland Not very ideal, it is difficult to play its due value
