The present disclosure relates to the field of water-saving irrigation technologies, in particular to a drip irrigator for film-mulching drip irrigation, a film-mulching irrigation assembly and an installation method of the film-mulching irrigation assembly.
The micro-spray irrigation technology is an advanced irrigation technology for effectively adjusting moisture in crops, and has the characteristics of water saving, energy saving, uniform irrigation, high irrigation quality and the like by adopting pipeline water-delivery. Further, combined with foliar fertilization and pesticide spraying on the crops, the micro-spray irrigation technology is high in atomization degree during the spraying process. In this way, the humidity of surfaces of the crops and the humidity of air are increased, the field microclimate is adjusted, the disease and insect pest is reduced, and both the quality and the yield of the crops are improved.
The existing micro-irrigation technology includes drip irrigation pipes, a drip irrigation pipe group and a micro-spraying pipe group. The drip irrigation pipes, the drip irrigation pipe group and the micro-spraying pipe group are prone to aging after frequently being irradiated under sunlight. Further, this micro-irrigation technology causes the rapid reduction of the humidity of soil after irrigation is finished, and thus crop moisture conservation is not facilitated. In addition, the existing drip irrigator inserted in soil is prone to being blocked, so that the efficiency of the drip irrigation is low and even the drip irrigation cannot be carried out continuously. For example, an emitter for drip irrigation and a drip irrigation device disclosed by the patent publication No. CN104684381B as well as an emitter for drip irrigation and a drip irrigation device with the emitter for drip irrigation disclosed by the patent application publication No. CN104853592A all have the problems that water loss in soil is too fast and the emitters are prone to being blocked.
In order to solve the problems, the present disclosure provides a drip irrigator for film-mulching drip irrigation, a film-mulching irrigation assembly and an installation method of the film-mulching irrigation assembly, which aims to solve the problems that water loss in soil is too fast and emitters are easily blocked.
The present disclosure aims to provide a drip irrigator for film-mulching drip irrigation, a film-mulching irrigation assembly and an installation method of the film-mulching irrigation assembly, so as to achieve the purposes that water loss in soil is slowed down and emitters are prevented from being easily blocked.
In order to achieve the purposes, the present disclosure provides the following scheme.
A drip irrigator for film-mulching drip irrigation includes a main pipeline, as well as an annular pipeline and a plurality of branch pipes sequentially arranged on the main pipeline from top to bottom and communicate with the main pipeline. An end of the main pipeline is closed end and an other end of the main pipeline is an opening end. Each of the branch pipes is provided with a plurality of emitters, the emitters are arranged on an upper surface of the branch pipe and communicate with the branch pipe. Water outlet holes are formed in an inner ring wall and an outer ring wall of the annular pipeline, and the opening end of the main pipeline communicates with a water conveying pipeline.
In some embodiments, a plane where the annular pipeline may be located may be perpendicular to the main pipeline, and the main pipeline may be arranged in a center of the annular pipeline and may communicate with the annular pipeline through a plurality of connecting pipes.
In some embodiments, the branch pipes may be distributed on the main pipeline at equal intervals, and a distance between every adjacent two of the branch pipes may range from 4 cm to 6 cm.
In some embodiments, an included angle between each of the branch pipes and the main pipeline may range from 30 degrees to 75 degrees.
In some embodiments, the closed end of the main pipeline may be conical.
In some embodiments, the main pipeline may be made of polyethylene.
In some embodiments, a distance between every adjacent two of the emitters may be 0.2 cm to 0.5 cm, and a length of each of the branch pipes may be 2 cm to 5 cm.
A film-mulching irrigation assembly includes the drip irrigator for film-mulching drip irrigation. The film-mulching irrigation assembly includes a main through pipe, a plurality of branch through pipes and a film. Upper surfaces of the main through pipe and the branch through pipes are mulched with the film. The branch through pipes are uniformly arranged on two sides of the main through pipe respectively and communicate with the main through pipe. One end of the main through pipe communicates with a micro-irrigation head pivot, an other end of the main through pipe is closed. An end, which is away from the main through pipe, of each of the branch through pipes is closed, and the drip irrigator for film-mulching drip irrigation is arranged on a lower surface of each of the branch through pipes.
In some embodiments, the main through pipe may be perpendicular to each of the branch through pipes.
An installation method of the film-mulching irrigation assembly includes the following steps: arranging a film on upper surfaces of a main through pipe and a plurality of branch through pipes in advance, and arranging drip irrigators for film-mulching drip irrigation on a lower surface of each of the branch through pipes; laying the film, the main through pipe and the branch through pipes which are arranged together in advance on a ground, and inserting the drip irrigators for film-mulching drip irrigation under the ground; and connecting one end of the main through pipe with a micro-irrigation head pivot, and closing an other end of the main through pipe.
Compared with the prior art, the present embodiment has the following technical effects.
Firstly, the emitters are arranged on the upper surface of each branch pipe, so that the emitters can be effectively prevented from being blocked by wet soil. Meanwhile, water outlet holes formed in the inner ring wall and the outer ring wall of the annular pipeline can be used for drip irrigation to the ground simultaneously, and the overall efficiency of the drip irrigation to the soil is guaranteed. In addition, in the film-mulching irrigation assembly, the main through pipe and the branch through pipes are mulched with the film, so the evaporation loss of water is reduced, sufficient water in the soil is guaranteed, and smooth growth of plants is guaranteed.
Secondly, the plane where the annular pipeline is located is perpendicular to the main pipeline, and the main pipeline is arranged in the center of the annular pipeline and communicates with the annular pipeline through a plurality of connecting pipes. That is to say, the annular pipeline can be horizontally placed on the ground, and wet drip irrigation to the ground is completed through the water outlet holes of the annular pipeline, which guarantees that water in the annular pipeline can irrigate the soil in a manner of the largest area and the fastest speed.
Thirdly, the included angle between each branch pipe and the main pipeline ranges from 30 degrees to 75 degrees, so that downward insertion of the main pipeline and the branch pipes is facilitated, and the resistance from the soil is reduced.
Fourthly, the main pipeline is made of polyethylene, which guarantees that the main pipeline cannot deform when being inserted into the soil.
