In order to solve the technical problems in the prior art, the invention provides the field crop needle irrigation system and the water demand testing method for the arid region, which have the advantages of simple structure, convenience in use, no soil moisture evaporation and leakage loss, capability of accurately irrigating crops and water conservation.
In order to achieve the purpose, the technical scheme adopted by the invention is that the needle irrigation system for the field crops in the arid region comprises a water storage tank and a water delivery pipe, wherein the water delivery pipe is arranged along the row spacing of the crops, a plurality of four-way pipe joints are arranged on the water delivery pipe, the 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 needle heads, the needle irrigation needle heads are respectively used for being inserted into the xylem parts of the crops, the water delivery pipe is provided with a small water pump, and the needle irrigation branch pipes are provided with pressure regulating valves, flow meters and flow control valves.
Preferably, the small water pump, the pressure regulating valve, the flow meter and the flow control valve are respectively connected with a main control system.
Preferably, the needle irrigation branch pipe is also provided with a filter.
A method for testing water demand of field crops in arid regions includes inserting needle of irrigation needle into xylem of crop, regulating valve openness of pressure regulating valve and flow control valve according to different crops, controlling pressure and flow rate, controlling flow rate at 2-30 ml/min, recording flow data of each crop by flow meter, measuring water potential value of each crop by plant water potential meter, recording, and determining water demand required by each crop in normal growth condition after growth period of 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 the crop 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 completely used for the crops, can utilize water, fertilizer and pesticide more efficiently, and greatly saves the using amount of the water, the fertilizer and the pesticide. Meanwhile, the fertilizer can directly act near the crop fruits, so that long-distance transportation of 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 normal growth of each crop or each crop in one growth period, and can realize targeted irrigation according to different crops, thereby really realizing water-saving irrigation and meeting the irrigation requirement of arid areas.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present 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 merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a arid area field crop needle irrigation system, including storage water tank 1 and raceway 2, raceway 2 arranges along the row of crop interrow, is provided with a plurality of four-way pipe joints 3 on raceway 2, and branch pipe 4 is irritated to the needle is connected with respectively to the both sides of four-way pipe joint 3, and needle irrigation syringe needle 5 is installed to the tip of branch pipe 4 is irritated to the needle, and needle irrigation syringe needle 5 is used for inserting the xylem of crop respectively, installs small-size water pump 6 on raceway 2, installs pressure regulating valve 7, flowmeter 8 and flow control valve 9 on the branch pipe 4 is irritated to the needle.
The invention adopts needle irrigation, so that the irrigation water adopts pure water. The whole system adopts that the raceway is arranged between the row of the crop, is provided with a plurality of four-way pipe joints on the raceway, and the four-way pipe joint is used for connecting the needle and irritates the branch pipe, installs small-size water pump on the raceway, and small-size water pump can provide certain water pressure for the raceway, makes the raceway be in the constant voltage 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 speed of each crop 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 speed of each crop can be accurately controlled through the main control system, and automatic control is realized. The needle irrigation branch pipe 4 is also provided with a filter to prevent impurities in water from entering the crop body.
When the water demand is tested, the needle of the needle irrigation syringe is inserted into the xylem of the crop, the valve openness of a pressure regulating valve and a flow control valve is adjusted according to different crops, the pressure and the flow are controlled, the flow rate is controlled to be 2-30ml per minute, a flow meter records the flow data of each crop, the water potential value of each crop is measured by a plant water potential meter and recorded, and the required water demand is determined under the condition that each crop normally grows after the growth period of the crop. The crop can be irrigated accurately in a targeted manner through the water demand information.
The present invention is not limited to the above preferred embodiments, but rather, any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
