A kind of agricultural water-saving irrigation system and water-saving irrigation method thereof

Abstract

The invention discloses an agricultural water-saving irrigation system and a water-saving irrigation method thereof: it comprises an irrigation water storage tank, a filter device and an irrigation water pipe; the water outlet of the irrigation water storage tank is communicated with the water inlet of the filter device; The water pipe includes a main water pipe, an above-ground irrigation water distribution pipe and an underground irrigation water distribution pipe, and the water outlet of the filter device communicates with the water inlet of the main water pipe; The water inlet is connected and arranged; the above-ground irrigation water distribution pipe is provided with a first liquid spray structure, and the underground irrigation water distribution pipe is provided with a second liquid spray structure; through the first liquid spray structure and the second liquid spray structure, the The irrigation water in the irrigation storage tank is diffused to the agricultural soil. There are two methods of above-ground sprinkler irrigation and underground drip irrigation, which can achieve the purpose of maximum water saving while performing reasonable irrigation according to the water shortage of crops in agricultural soil at various periods.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an agricultural water-saving irrigation system and a water-saving irrigation method thereof. Background technique [0002] It is predicted that by 2050, the world's total population will increase from the current 7 billion to 9 billion, and the human demand for food will increase by 70% to 100% at the current level. [0003] The world's fresh water resources are increasingly scarce, and human demand for food is also increasing. Fresh water resources have become a threat to agricultural development and the security of the world's food supply. To solve the problem of limited arable land, shortage of fresh water resources and rising world food demand, the development of water-saving irrigation becomes the key. [0004] Water-saving irrigation is an irrigation measure to obtain the maximum yield or profit with the minimum amount of water, that is, to maximize the cro...

Problems solved by technology

[0005] However, often a single water-saving irrigation method cannot achieve the best effect on agricultural irrigation, which will inevitably lead to waste of water resources or insufficient irrigation, which will affect the growth of crops; To achieve the purpose of water saving, and can fully guarantee the water demand of crops; thus, an agricultural water-saving irrigation system is designed
