Long water device, long water device irrlgation system and application of the same in alkaline land improvement

Abstract

The invention relates to a water device and an irrigation system of the water device and the application thereof in the modification of saline and alkali lands. The traditional agricultural irrigation methods such as pour irrigation, canal irrigation are of coarse and low effect with the water utilization ratio being 10 percent approximately, thus the waste of water resource is astonishing, and furthermore, a series of problems such as land salinization are frequently and easily caused. In order to overcome the defects in traditional irrigation, irrigation methods of spray irrigation, drop irrigation, etc. are popularized at home and abroad. However, the water utilization rate of such irrigation methods is only around 50 percent; still approximately half of the irrigation water is wasted. The water device of the invention comprises a semipermeable membrane or a microporous permeable membrane. The semipermeable membrane or the microporous permeable membrane, by adopting the methods of heat seal and mechanical seal, is made into a baggy water container with a water inlet that is sealed and used in agricultural irrigation, or the blow-moldable raw material with the property of the semipermeable membrane or the microporous permeable membrane are utilized to blow-mold the closed container with the water inlet that is sealed and used in agricultural irrigation. The product of the water device is applied in water-saving agricultural irrigation and the modification of saline and alkali lands that can reduce water consumption.

Description

Technical field: [0001] The invention relates to a sealed water container for agricultural irrigation made of a semi-permeable membrane or a microporous permeable membrane and an application thereof. Background technique: [0002] Agricultural irrigation water occupies more than 50% of the total water resource consumption. In the case of global water shortage, saving agricultural water and reducing the ineffective consumption of water resources are urgent problems to be solved for sustainable development. [0003] Traditional agricultural irrigation methods such as watering and canal irrigation are crude and inefficient, with a water utilization rate of about 10%, an astonishing waste of water resources, and often lead to a series of problems such as land salinization. In order to overcome the disadvantages of traditional irrigation, irrigation methods such as sprinkler irrigation and drip irrigation have been popularized at home and abroad, but the water utilization rate of...

AI Technical Summary

Problems solved by technology

[0003] Traditional agricultural irrigation methods such as watering and canal irrigation are crude and inefficient. The water utilization rate is about 10%. The waste of water resources is astonishing, and it is often easy to cause a series of problems such as land salinization.

In order to overcome the disadvantages of traditional irrigation, irrigation methods such as sprinkler irrigation and drip irrigation have been promoted at home and abroad, but the water utilization rate of these irrigation methods is only about 50%, and about half of the irrigation water is still wasted
