Problems solved by technology

[0002] With the gradual improvement of automation procedures, large-scale automated systems have also begun to be used for irrigation in the process of agricultural and forestry planting. In the process of plant growth, not only water spraying but also fertilization is required. At this time, if another system is set up to spray fertilizer It will appear repetitive work, and the existence of the irrigation system will affect the construction of the fertilizer spraying system, so it is necessary to consider the combined use of the irrigation system and the fertilization system, and how to clean the pipeline after fertilization has become an inevitable problem

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0030] like figure 1 As shown, a water and fertilizer integrated irrigation system includes a main pipeline 7 arranged along the ground and branch pipelines 71 connected to the main pipeline. 71 is arranged obliquely upward from the main pipeline 7, so that the residual liquid in the branch pipeline 71 can naturally return to the main pipeline 7 in a natural state, and a valve is provided at the connection between each branch pipeline 71 and the main pipeline 7 (Fig. Not shown), the last branch pipe 71 arranged along the water flow direction of the main pipe 7 is connected with a vacuum pump 72; each branch pipe is provided with a nozzle 8. The using method of the water and fertilizer integrated irrigation system provide...

Abstract

The invention provides a water-fertilizer integrated irrigation system, which comprises a main pipeline arranged along the ground, and branch pipelines connected with the main pipeline, wherein when liquid in the main pipeline flows into the branch pipelines, gravity needs to be overcome; nozzles are arranged on the branch pipelines; each branch pipeline is independently provided with a valve; a vacuum pump is connected onto the last branch pipeline arranged along a water flowing direction of the main pipeline. The water-fertilizer integrated irrigation system provided by the invention has theadvantages that after fertilizing, the liquid remained in the pipelines can be pumped back into the main pipeline through the vacuum pump and is discharged through the last branch pipeline, so that irrigation and fertilization can be realized conveniently through the system, and remained fertilizers can be cleared; the nozzles can automatically rotate by 360 degrees so as to spray uniformly, so that water is saved, atomized irrigation and fertilization can be realized on leaf surfaces, the leaf surfaces can be prevented from being scorched, and the system has better irrigation and fertilization effects and a favorable popularization prospect.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry irrigation, in particular to a water and fertilizer integrated irrigation system. Background technique [0002] With the gradual improvement of automation procedures, large-scale automated systems have also begun to be used for irrigation in the process of agricultural and forestry planting. In the process of plant growth, not only water spraying but also fertilization is required. At this time, if another system is set up to spray fertilizer It will appear repetitive work, and the existence of the irrigation system will affect the construction of the fertilizer spraying system, so it is necessary to consider the combined use of the irrigation system and the fertilization system, and how to clean the pipeline after fertilization has become an inevitable problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water a...
