Embodiment 1

[0024] The micro-moisturizing tube is composed of: a flexible tube with a double-layer structure composed of an inner tube 1 and an outer tube 2 of a water-permeable protective sleeve, and the inner tube wall has micro-through holes 3 with a diameter of 10-900 nm.

Embodiment 2

[0026] The series micro-moisturizing irrigation system comprises the following steps: connecting a group of the above-mentioned micro-moisturizing pipes to a water supply pool 6 through a valve 5 connected end to end through a straight-through 4.

[0027] This embodiment is suitable for small, irregularly shaped land, or a garden system with an irregular pattern design, where the microfluidic pipe is both a water delivery pipe and a water feeder.

[0028] According to the principles of physics, in a static pressure system, every point in the system experiences the same pressure. The pipelines connected in the above way can be regarded as a quasi-static pressure system. The internal pressure of the head end and the tail end of the pipe are basically the same, and the water output will not be uneven due to the pressure drop along the way.

Embodiment 3

[0030] The parallel micro-moisturizing irrigation system comprises the following steps: connecting a group of the above-mentioned micro-moisturizing pipes to a water supply main pipe 8 through a tee 7 respectively, and the water supply main pipe is connected to a water supply pool through a valve.

[0031] The length of the micro-running pipe is the same as that of the ridge of the plot, and it is buried under the ridge. The length of each plastic short pipe is the same as the ridge spacing, and the total length of the plastic pipe is the same as the width of the plot.

Abstract

The invention relates to a micro-moistening pipe and a micro-moistening irrigation system. The traditional agricultural irrigation methods, such as water irrigation, canal irrigation and the like, are coarse and low in efficiency, and the utilization rate of water is about 10%, therefore, the waste of water resources is astonishing, and a series of problems, such as soil salinization and the like, are easy to cause. For overcoming the disadvantages existing in the traditional irrigation, the irrigation methods, such as sprinkling irrigation, trickle irrigation and the like, are spread and applied at home and abroad, but when these irrigation methods are used, the utilization rate of water is only about 50%, and about half of irrigation water is still wasted. The micro-moistening pipe comprises a hose with a double-layer structure, and the hose is composed of an inner pipe (1), and an outer pipe (2) of a permeable protective sleeve, wherein the wall of the inner pipe is provided with micro through holes (3), and the diameter of the micro through hole is 10-900 nm. The micro-moistening pipe and the micro-moistening irrigation system provided by the invention are used for water-saving agricultural irrigation and water-saving reclamation on saline-alkali lands.

Description

Technical field: [0001] The invention relates to a sealed water container for agricultural irrigation made of semi-permeable membrane or micro-permeable membrane and its application. Background technique: [0002] The emergence of irrigated agriculture is a huge progress of agricultural civilization. In recent years, high-efficiency irrigation and water-saving irrigation have become the core and development direction of irrigation technology research. Various irrigation techniques such as sprinkler irrigation, infiltration irrigation, and drip irrigation have appeared successively, but the various technical methods that have been formed before, including the ancient irrigation, are all intermittent irrigation with a large amount of water. Different irrigation methods such as drip irrigation have great differences in the irrigation cycle, irrigation frequency and single water consumption of irrigation, but what these four irrigation methods have in common is that there is a p...
