Loess tableland region furrow hillside land water accumulation irrigating system and building method thereof

Abstract

The invention relates to land reclamation, in particular to a loess tableland region furrow hillside land water accumulation irrigating system, and solves the technical problems of existing loess tableland region furrow hillside land of proneness to collapse caused by water loss and soil erosion due to rainfall in summer and autumn and soil productivity lowering caused by the fact that irrigationwater source needs cannot be met in winter and spring. The system is characterized by comprising a terrace water accumulation unit and a drainage and irrigation system, the terrace water accumulationunit comprises multiple field parcels in stepped arrangement, each field parcel comprises a ridge and a field surface, each ridge is arranged on one side, away from a field parcel of the upper level,of the corresponding field surface, and a drainage ditch is arranged in the middle of each ridge and divides the ridge into an inner ridge and an outer ridge; multiple seeping holes communicated withthe corresponding field surface and the corresponding drainage ditch are formed in the bottom of each inner ridge, and one side, close to the corresponding ridge, of each field surface is away from one side away from the ridge. The invention further provides a building method of the system.

Description

technical field [0001] The invention relates to a land improvement method, in particular to a water collection irrigation system for gully slopes in the loess plateau area and a construction method thereof. Background technique [0002] The loess platform is a loess platform that is covered by loess on the platform of the valley terrace and distributed in strips along the valley. The platform generally slopes towards the valley. Slope land is the main type of cultivated land in the loess plateau area. Land consolidation is an important measure to stabilize the area of ​​cultivated land, improve the quality of cultivated land, increase food production, and alleviate the conflict between man and land. The spatial distribution of precipitation in the loess plateau area is uneven. There is less rain in winter and spring, more rain in summer and autumn, and more torrential rains in summer and autumn, which leads to frequent soil erosion in summer and autumn. However, crops often...

Problems solved by technology

[0003] In order to solve the technical problem that the slope land in the loess plateau area is caused by rainfall in summer and autumn, which can easily cause field sills to collapse, and the demand for irrigation water sources cannot be met in winter and spring, resulting in a decline in land productivity, the invention provides a kind of ditch slope land in the loess plateau area Water harvesting irrigation system and construction method thereof
