Agricultural water conservation irrigation system and water conservation irrigation method thereof

Abstract

The invention discloses an agricultural water conservation irrigation system and a water conservation irrigation method thereof. The system comprises an irrigation water storage box, a filtering device and an irrigation water pipe; a water outlet of the irrigation water storage box is communicated with a water inlet of the filtering device; the irrigation water pipe comprises a main water pipe, aground irrigation water dividing pipe and an underground irrigation water dividing pipe, and a water outlet of the filtering device is communicated with a water inlet of the main water pipe; a water outlet of the main water pipe is communicated with water inlets of the ground irrigation water dividing pipe and the underground irrigation water dividing pipe; the ground irrigation water dividing pipe is provided with a first liquid spraying structure, and a second liquid spraying structure is arranged on the underground water dividing pipe; irrigation water in the irrigation water storage box isscattered to agricultural soil through the first and second liquid spraying structures. According to the system, two manners of ground irrigation and underground irrigation are arranged, reasonable irrigation can be conducted under the water scarcity situation of each time section of the crops in agricultural soil, and the purpose of maximum water conservation is achieved.

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 irrigat
