Abstract

The utility model relates to an agricultural underground water supply pipe, which is suitable for the cultivation of the vegetable, the flower and the fruit tree, particularly suitable for farmland planting, tree irrigation and the reconstruction of mountain areas, hills and sandy wastelands. The middle portions on the two sides of the pipe wall of the water supply pipe are symmetrically provided with two rows of main water supply holes. Two rows of assistant water supply holes are symmetrically provided under the main water supply holes. When used, the water supply pipe is buried in the underground portion. The water supply holes are corresponding to the root portion of the crop and then the water in a water ditch is introduced into the water supply pipe, the water slowly soaks into the underground portion through the main water supply holes and the assistant water supply holes to enable the water to be directly dropped into the root portion of the crop to be helpful for the growth of the crop.

Description

Agricultural underground water delivery pipe

The utility model is a water-supply-pipe under a kind of farming land.Be applicable to the cultivation of vegetables, flowers, fruit tree, grape etc., be specially adapted to the transformation in agriculture field planting, trees pouring and mountain area, hills, sandy wasteland.

Present conventional irrigation method is to build the ditch diversion, and furrow are divided every the ridge in the land for growing field crops, and disposable irrigating makes the crops have enough moisture content to absorb within a certain period of time.Irrigate in this way, even excess surface water reaches 20-30mm deeply, in the good area of soil water permeability, the moisture content of actual absorption has only about 20%, and in the bad area of soil water permeability, it is more that water just runs off.Because water is to flow from high to low, also be flushed away by the impact fertilizer of water again, so lower local water, fertilizer all compare abundance, relatively high local water, fertilizer have all lacked, and have so just caused whole farmland water, fertile inhomogeneous, after especially the moisture content of ground surface dries, soil compaction, the soil moisture conservation of also will hoeing up weeds was both wasted man-hour like this, and it is inhomogeneous again to apply fertilizer, be unfavorable for the growth of crops, though some places are made furrow with plastic tube, tube wall is thicker, the cost height.

The purpose of this utility model be to provide that a kind of tube wall is thin, in light weight, price is low, water saving, economize on electricity, water and soil be difficult for running off, and direct water-supply-pipe under the farming land of crop root part drip irrigation.

The purpose of this utility model is achieved in that this water-supply-pipe plastic production, and tube wall 0.25-1mm is thick, and it is the hole, garden of 3-8mm that two row's diameters are arranged on the centre position, both sides of tube wall symmetrically, claims main water supply hole, and the distance between the Kong Yukong is 15-30mm.In main water supply hole bottom two row's diameters being arranged symmetrically is the small garden hole of 1-3mm, claims auxilliary water supply hole, and the distance between the Kong Yukong also is 15-30mm.Main water supply hole and auxilliary water supply hole are parallel to each other.During use water-supply-pipe is imbedded undergroundly, water supply hole is facing to crop root part.And then in the water introduction water-supply-pipe with the ditch, water just slowly permeates the ground from main water supply hole and auxilliary water supply hole, and this drip irrigation mode can make water directly splash into crop root part, makes the crops often keep being beneficial to the growth in crops than adequate moisture.

The utility model is reasonable in design, simple in structure, easy to manufacture, physical and chemical performance is stable, tube wall is thin, in light weight, cheap, easy to use, this water-supply-pipe can directly supply water to crop root part, be beneficial to the growth of crops, field management is convenient in water saving, economize on electricity, saving working hour, and more conventional irrigation method water saving is more than 90%, water and soil is difficult for running off, weeds are difficult for growing, and soil does not harden, and need not intertill to keep soil that air permeability and good is arranged, improve the availability in soil, relatively also improved the per unit area yield on every mu of ground.

Below in conjunction with accompanying drawing the utility model is further described:

Accompanying drawing is a water-supply-pipe schematic diagram under the farming land

Among the figure: (1) is that main water supply hole (2) is that auxilliary water supply hole (3) is a tube wall

On the centre position, both sides of water-supply-pipe tube wall (3), two row's main water supply holes (1) are arranged symmetrically, in the bottom of main water supply hole the auxilliary water supply hole (2) of two rows is arranged.During such as agricultural irrigation, (according to the density degree of crops growth) buries water-supply-pipe one time at a certain distance in big field, be parallel to each other for one time one time, except that an end of a water-supply-pipe is done the water inlet, remaining water-supply-pipe all is connected with bend pipe with the two ends of water-supply-pipe, the internal diameter of bend pipe greater than the about 0.5mm of the external diameter of water-supply-pipe about, during connection, water-supply-pipe is enclosed within the bend pipe gets final product, do not have water supply hole on the bend pipe.During the tube wall 3/4 of water-supply-pipe placed into the soil, it is about to expose 1/4(), make water supply hole face toward the root of crops, and then the water of ditch or water pipe introduced in the water-supply-pipe from the water-supply-pipe water inlet, water is just from main water supply hole (1) and auxilliary water supply hole (2), slowly infiltrate in the soil, make the crops remain enough moisture content, be beneficial to the growth in crops.After the maturation of crops, before the harvesting, take out pipe, remove foreign material, standby behind the airing.Also can irrigate trees with this pipe.

This water-supply-pipe can be made all size (length, diameter do not wait) as required.The material of water-supply-pipe is plastics.Also can make of other material.

Claims

1, water-supply-pipe under a kind of farming land has straight tube and bend pipe, it is characterized in that: on the centre position, both sides of this water-supply-pipe tube wall, it is 3-8mm that the main water supply hole diameter of two rows is arranged symmetrically, and in the bottom of main water supply hole, it is 1-3mm that the auxilliary water supply hole diameter of two rows is arranged symmetrically.

2, according to water-supply-pipe under the described farming land of claim 1, it is characterized in that: this water-supply-pipe plastic production, the thickness of tube wall is 0.25-1mm.
