Embodiment 1

[0029] The meaning of long water device and long water irrigation system:

[0030] Utilizing the physical characteristics of semi-permeable membranes or microporous permeable membranes, and according to the principle that water can drive directional flow when there is a potential energy gradient on both sides of the semi-permeable membranes, the semi-permeable membranes or microporous permeable membranes are made into containers that can be used for agricultural and forestry irrigation. This container can double the effective irrigation time of the same amount of water. This kind of container made of semi-permeable membrane or microporous water-permeable membrane for irrigation purpose is called a container that can prolong the effective irrigation time of water, referred to as a water dispenser for short. A network of irrigation systems can be formed by connecting multiple long water devices with water pipelines, which is called long water irrigation system. The long water d...

Embodiment 2

[0044] long water irrigation system

[0045] If a plurality of elongated fountains in Embodiment 1 are connected with the water delivery pipe network system, a networked irrigation system can be formed. (see figure 2 ) A long water device is buried next to each plant, and the water sent by the water pipeline can be continuously supplied to the plants. In this case, each small long sprinkler is equivalent to a drip irrigation head in the drip irrigation system, but the long water irrigation system is more water-saving than the drip irrigation system, and does not need power equipment such as a booster pump to drive the system during operation .

[0046] The irrigation system of this structure is suitable for large-scale orchards, nurseries and economic forests, and can also be used in some agricultural production occasions.

Embodiment 3

[0048] The second structure of the long water irrigation system, the long water device of the long tube type in embodiment 1 or embodiment 2 is directly connected with the water delivery main pipe, which can be structured as image 3 Another form of irrigation system is shown.

[0049] refer to image 3 As shown, the branch pipe in the previous irrigation system is replaced by a long tubular long fountain, which is directly connected to the main pipe, which not only plays the role of water supply, but also plays the role of water delivery. The pipe is buried next to the planted crops in a ridge, and when the pipe is filled with water, the soil where the pipe passes is moist, and the plants can be well irrigated. The long water irrigation system with this structure can replace the existing sprinkler irrigation or drip irrigation system, and can be used for both protected planting and field production.

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...
