Land-saving and water-saving methods for farmland drainage and irrigation mode conversion

Abstract

The invention provides a land-saving and water-saving technology for converting farmland drainage and irrigation patterns, wherein the land-saving and water-saving technology is low in cost and fine in use effect. The technical scheme includes that farmland canal system water conservancy is converted into pipeline water conservancy, the technology mainly includes project area reconnaissance, design, construction and operation, technology implementation includes four steps: firstly, adopting a multistage underground pipe land-saving technology; secondly, converting uncovered canal irrigation into pipeline irrigation; thirdly, building a multifunctional enhanced drainage station; fourthly, building a remote automatic regional water resource regulation system. Cultivated land is effectively saved, the area of the cultivated land can be increased, the quality of the cultivated land is improved, regional water resources are effectively and comprehensively regulated, and overall agricultural production capacity is improved. The land-saving and water-saving technology is fine in use effect, long in duration time and suitable for large-area popularization and use, and huge social benefits, economic benefits and ecological benefits are generated.

Description

Technical field: [0001] The invention relates to the technical field of farmland water conservancy engineering, in particular to a land-saving and water-saving method for farmland drainage and irrigation mode conversion. Background technique: [0002] The underground pipe drainage technology is a kind of farmland drainage technology that was introduced into my country in the 1870s. The original purpose of the introduction was to control waterlogging and soil salinization by installing a dark pipe system. In the past 40 or 50 years, through the research and improvement of our country's scientific research and engineering technicians, a complete set of engineering technology suitable for the improvement of saline-alkali land in our country has gradually been formed, and it has been applied on a large scale in Xinjiang, Ningxia and the Yellow River Delta. After the implementation of the underground pipe alkali improvement project, the effect of alkali improvement is remarkable....

AI Technical Summary

Problems solved by technology

Although this method has a good effect in improving alkali, the open ditches and open channels built in the project area occupy a large amount of valuable cultivated land resources, and the land occupation can reach 15%-30% of the total land area of ​​the project area.

At the same time, since a large piece of land is divided into many small farmlands, it brings inconvenience to the implementation of mechanized operations and reduces the efficiency of agricultural production.
