Root irrigation and root irrigation system

Abstract

The invention discloses a root irrigation tube which comprises a hollow tube body with two open ends; the inside of the tube body is divided to form a first side chamber and a second side chamber by a dividing wall extending along a length direction; the side wall of the first side chamber opposite to the dividing wall is provided with an opening extending along the length direction; a plurality of communicated water outlet holes are arranged on the dividing wall by a certain interval along the length direction; the invention also comprises a baffle plate which is movably arranged in the first side chamber and the opening along the length direction and blocks the water outlet holes; a water outlet gap is formed between the baffle plate and the edges of the inner side surface and the opening of the first side chamber. The invention also comprises a root irrigation system which includes a head part hinge, a transmission pipeline and the root irrigation tube. Single side water discharge is adopted by the root irrigation tube, thus prolonging the transmission distance of irrigation water, improving the irrigation efficiency, being convenient for carrying out fast and simple arrangement, being able to be matched and connected with a standard pipeline connector without being equipped with a special connector and reducing the cost. The root irrigation tube is made from soft materials and is not restrained by terrain when being buried.

Description

Technical field [0001] The invention relates to a root irrigation pipe and a root irrigation system suitable for agricultural irrigation. Background technique [0002] At present, in the application of agricultural irrigation, underground pipeline infiltration irrigation has been paid more and more attention as a high-efficiency water-saving irrigation technology. The so-called underground pipeline seepage irrigation is to bury the seepage irrigation pipe with seepage holes on the pipe wall under the ground surface, transport irrigation water (or liquid fertilizer, pesticide, gas) to the seepage irrigation pipe through the pipeline and seep out from the seepage hole, and then With the help of the capillary action of the upper soil, water (or liquid fertilizer, pesticide, gas) is diffused to the upper soil of the active layer of the crop root system, and absorbed and utilized by the root of the crop. [0003] Compared with the traditional irrigation technology, underground p...

Problems solved by technology

The disadvantages of underground pipeline seepage irrigation are: the seepage hole of the seepage irrigation pipe is easy to block; the surface soil humidity is poor, which is not good for crop emergence and seedling growth; in the soil with strong water permeability, there is still a certain amount of leakage loss; maintenance It is difficult, the investment is large, and the construction is laborious; the burial of the infiltration irrigation pipe is limited by the slope and length; too little irrigation water will cause the soil to return to salt, so it is not suitable for use on saline-alkali land, etc.

The blockage of the infiltration irrigation pipe reduces the amount of irrigation water, which brings the following problems: first, the salinity at the bottom of the soil rises with the capillary, forming secondary salinization; second, when the crop grows stronger, it cannot provide enough water and the Inhibition of crop growth leading to death

However, the application shows that this new type of pipeline and irrigation device needs to be further improved. For example, the pipeline uses both sides to discharge water at the same time, and the distance that irrigation water can be transported is relatively short; Quick and easy layout; the outer wall of the pipeline is protruded with a water seepage part, and the shape of the pipe body is a special-shaped body, which cannot be matched with the existing standard pipeline connectors. It is necessary to make and equip special connectors, which increases the manufacturing and installation. The cost; the pipeline is made of hard materials, and the burial is limited by the terrain
