Novel water-saving technology for underground irrigation and seepage of farmland

Abstract

The invention discloses a novel water-saving technology for underground irrigation and seepage of farmland. The novel water-saving technology for underground irrigation and seepage of farmland comprises construction steps as follows: step one, mounting of a multi-energy tank; step two, mounting of a main pipeline; step 3, mounting of primary pipelines; step four, mounting of secondary pipelines; step five, mounting of ternary pipelines; and step six, mounting of seepage guide films and anti-blocking sand and stone. The technology has the benefits as follows: isobaric water outgoing, uniform water outgoing and no blockage of water outlets are realized, the early mounting cost is low, the service life is long after mounting, users can benefit from one project, waste of water resources can bereduced, the utilization rate of water resources can be increased, and the technology has very great significance in developing high-yield, high-quality and efficient agriculture and green agriculture and protecting the ecological environment.

Description

technical field [0001] The invention relates to the field of farmland irrigation and water saving, in particular to a new technology of farmland underground irrigation and water saving. Background technique [0002] my country is a country that lacks water resources. The average water resource per mu is about 1 / 2 of the world's average level, and the per capita water resource is only 1 / 4 of the world's average level, and the distribution is unbalanced. Therefore, it can be seen that my country's available water lower. Among them, North China (Beijing, Tianjin, Hebei, Shandong, Inner Mongolia) accounts for 4.54% of the country's water resources, 19% of the population and 24% of the GDP, but the degree of water resource development and utilization has exceeded 70%. In regions with severe shortage of water resources, with the development of society and economy, the demand for water will increase, and the contradiction between supply and demand of water resources will become inc...

AI Technical Summary

Problems solved by technology

The main disadvantage of micro-irrigation is that the water is uneven, the water outlet is easy to block, and the investment is high, which makes it impossible to promote it on a large scale.

[0009] Now there are many kinds of water-saving irrigation technologies in the world, and there are as many as five or six kinds of sprinkler irrigation alone, but none of them can be promoted in large-scale fields

Over the years, many water conservancy experts at home and abroad have also taken "underground irrigation" as a frontier topic in agricultural water-saving research and made great efforts to publicize it. Evenly” and “water outlet is easy to block” two problems have not been broken so far
