Abstract
The invention relates to a needle irrigation system for field crops in arid areas and a water demand testing method, which belong to the technical field of agricultural irrigation.
Description
Technical Field
The invention relates to a needle irrigation system for field crops in arid regions and a water demand testing method, and belongs to the technical field of agricultural irrigation.
Background
The drought area has the problems of low precipitation, drought climate, strong illumination and the like, water is difficult to exist on the surface, but people living in the drought area and the need of farming, which is indispensable for water, and equipment is needed to collect water and irrigate crops. However, due to less rain of crops in arid areas, how to accurately irrigate the crops according to the water demand of normal growth of the crops is a technical problem which needs to be solved.
Disclosure of Invention
The invention provides a needle irrigation system for field crops in arid regions and a water demand testing method, which are simple in structure, convenient to use, free of soil moisture evaporation and leakage loss, capable of accurately irrigating crops and saving water.
In order to achieve the above purpose, the technical scheme adopted by the invention is that the needle irrigation system for field crops in arid regions comprises a water storage tank and a water delivery pipe, wherein the water delivery pipe is arranged between rows of crops, the water delivery pipe is provided with a plurality of four-way pipe joints, two sides of each four-way pipe joint are respectively connected with a needle irrigation branch pipe, the end parts of the needle irrigation branch pipes are provided with needle irrigation needles which are respectively used for being inserted into xylem of the crops, the water delivery pipe is provided with a small water pump, and the needle irrigation branch pipes are provided with a pressure regulating valve, a flowmeter and a flow control valve.
Preferably, the small water pump, the pressure regulating valve, the flowmeter and the flow control valve are respectively connected with the main control system.
Preferably, a filter is further installed on the needle irrigation branch pipe.
A method for testing the water demand of crops in arid area includes such steps as inserting needle irrigation needle in the wood part of crops, regulating pressure regulating valve and flow control valve, controlling pressure and flow rate to 2-30ml per minute, recording the flow data of each crop by flowmeter, measuring the water potential value of each crop by plant water potential meter, recording, and determining the water demand of each crop.
Compared with the prior art, the invention has the following technical effects: the invention adopts needle irrigation, and the needle head is directly inserted into the xylem of crops for irrigation; compared with the existing irrigation system, the irrigation system can directly transport water into crops, has no soil water evaporation and leakage loss, is totally used for crops, can more efficiently utilize water, fertilizer and medicine, and greatly saves the dosage of water, fertilizer and medicine. Meanwhile, the water can also directly act near the crop fruits, so that long-distance transportation of the water in the plant body is avoided, and the water can be directly used for improving the crop yield.
In addition, the system can accurately measure the water quantity required by each plant of crop or each crop in one growth period, and can realize the water-saving irrigation according to the pointed needle irrigation of different crops, thereby meeting the irrigation requirement of arid areas.

Fig. 1 is a schematic structural view of the present invention.
Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, the needle irrigation system for field crops in arid regions comprises a water storage tank 1 and a water delivery pipe 2, wherein the water delivery pipe 2 is arranged along the rows of crops, a plurality of four-way pipe connectors 3 are arranged on the water delivery pipe 2, two sides of each four-way pipe connector 3 are respectively connected with a needle irrigation branch pipe 4, the end parts of the needle irrigation branch pipes 4 are provided with needle heads 5, the needle irrigation needle heads 5 are respectively used for being inserted into the xylem of the crops, a small water pump 6 is arranged on the water delivery pipe 2, and a pressure regulating valve 7, a flowmeter 8 and a flow control valve 9 are arranged on the needle irrigation branch pipes 4.
The invention adopts needle irrigation, so that the irrigation water adopts pure water. The whole system adopts that the water pipe is arranged between rows of crops, a plurality of four-way pipe connectors are arranged on the water pipe, the four-way pipe connectors are used for connecting needle irrigation branch pipes, a small water pump is arranged on the water pipe, and the small water pump can provide certain water pressure for the water pipe, so that the water pipe is in a constant pressure state. When the pressure regulating valve 7 and the flow control valve 9 are arranged on the needle irrigation branch pipe, the flow and the flow velocity of each plant of crops can be accurately controlled through the pressure regulating valve 7 and the flow control valve 9. The small water pump 6, the pressure regulating valve 7, the flowmeter 8 and the flow control valve 9 are respectively connected with a main control system. The flow and the flow velocity of each plant of crops can be precisely controlled through the main control system, so that automatic control is realized. The needle irrigation branch pipe 4 is also provided with a filter to prevent sundries in water from entering the crop.
When the water demand test is carried out, the needle irrigation needle head is inserted into the xylem of crops, the opening of the pressure regulating valve and the opening of the flow control valve are regulated according to different crops, the pressure and the flow are controlled, the flow rate is controlled to be 2-30ml per minute, the flow data of each crop is recorded by the flow meter, the water potential value of each crop is measured by the plant water potential instrument, the water potential value is recorded, and the water demand required by each crop under the condition of normal growth is determined after the growth period of the crops. Through the information of the water demand, crops can be accurately irrigated in a targeted manner.
The foregoing description of the preferred embodiment of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
