[0037] Example 1

[0038] like Figure 1As shown, a water-fertilizer-gas-heat integrated drip irrigation intelligent control device comprises a water-fertilizer integrated machine 1, a drip irrigation unit 2, a fertilizer unit 3, a heating unit 4, a fixing unit 5 and a monitoring unit. The fertilizer inlet of the water-fertilizer integrated machine 1 is connected with the fertilizer unit 3, the drip irrigation unit 2 is connected with the liquid outlet of the water-fertilizer integrated machine 1, the drip irrigation pipe 21 of the drip irrigation unit 2 is detachably connected with the drip irrigation ring 22 of the fixing unit 5, and the temperature sensor, pH sensor, soil moisture sensor and conductivity sensor of the monitoring unit are electrically connected with the water-fertilizer integrated machine 1.

[0039] The integrated water and fertilizer machine 1 controls the amount of water or liquid fertilizer provided to the plants, and irrigates or fertilizes the land through the drip irrigation unit 2. The fertilizer is stored in the fertilizer unit 3, and the integrated water and fertilizer machine 1 transports the fertilizer in the fertilizer unit 3 to the drip irrigation unit 2 through the heating unit 4 according to demand. The heating unit 4 can choose whether to heat according to demand. The temperature sensor, pH sensor, soil moisture sensor and conductivity sensor of the monitoring unit are installed in the soil at the plant to monitor the soil status, so as to facilitate timely replenishment of water or fertilizer for plant growth.

[0040] When it is necessary to provide a suitable temperature for the microbial fertilizer in a low temperature environment, the heating unit 4 is turned on to transport water of suitable temperature to the fertilizer tank 31 where the microbial fertilizer is located, and heat and keep warm to maintain the optimum temperature required by the microorganisms in the microbial fertilizer. The heating unit 4 can also heat other fertilizers or irrigation water, and the heated water or fertilizer can heat the soil in a low temperature environment, thereby changing the temperature for root growth and promoting normal growth of plants.

[0041] like Figure 5-6 As shown, the fixing frame 51 of the fixing unit 5 is connected to the drip irrigation pipe 21, a fixing cavity 52 is provided in the center of the fixing frame 51, and supporting legs 53 are provided on both sides of the fixing cavity 52 of the fixing frame 51. One end of the rotating cover 54 at the top of the fixing cavity 52 is hinged to the top of the supporting leg 53, and the clamping block 55 at the other end of the rotating cover 54 is connected to the clamping groove 56 at the top of the other supporting leg 53. A fixing hole 1 is provided on the flexible clamping block 55, and a plurality of fixing holes 2 are provided on the side wall of the clamping groove 56. The clamping block 55 is connected to the clamping groove 56 by the fixing pin 58 through the fixing hole 1 and the fixing hole 2. By providing a plurality of fixing holes 2, the length of the clamping block 55 entering the clamping groove 56 can be adjusted, and it can be selected whether to place the thermal insulation layer 24.

[0042] The fixing frame 51 in the fixing unit 5 fixes the drip irrigation pipe 21 near the plant to ensure effective drip irrigation of the plant by the drip irrigation pipe 21. The drip irrigation pipe 21 is placed in the fixing cavity 52, and a heat preservation layer 24 can be placed between the drip irrigation pipe 21 and the rotating cover 54 to keep the water or fertilizer flowing in the drip irrigation pipe 21 warm in a low temperature environment. The height of the drip irrigation pipe 21 can be adjusted by the supporting legs 53. When drip irrigation is performed under the film, the covering film can be supported to a certain height by the drip irrigation pipe 21 and the fixing frame 51 to prevent the ground film from directly contacting the soil and contaminating the soil.

[0043] like Figure 4 As shown, the drip irrigation ring 22 is evenly provided with a number of drip irrigation holes along the circumference, the outer cover of the drip irrigation ring 22 is provided with a heat preservation layer 24, and one side of the drip irrigation ring 22 is provided with a threaded sleeve threadedly connected to the branch pipe head 23. It is optional to use the drip irrigation ring 22, and the drip irrigation ring 22 is connected to the branch pipe head 23 of the drip irrigation pipe 21. When the branch pipe mouth is not connected to the drip irrigation ring 22, a mounting cover is connected. Plants are planted in the center of the drip irrigation ring 22. In a low temperature environment, the drip irrigation ring 22 can evenly heat up the root system of the plant for irrigation. The setting of the heat preservation layer 24 keeps the water or fertilizer in the drip irrigation ring 22 warm, and at the same time, the heat preservation layer 24 absorbs solar energy for heating, avoiding heat dissipation during the transportation of water or fertilizer, and ensuring the promotion of root growth.

[0044] The fertilizer unit 3 is provided with a plurality of fertilizer tanks 31, which are connected to the fertilizer inlet of the water-fertilizer integrated machine 1 through a fertilizer outlet pipe 39, and a water inlet 32 ​​at the top of the fertilizer tank 31 is connected to the water inlet pump 6 of the water-fertilizer integrated machine 1. A stirring pump 33 is provided on the top of the fertilizer tank 31, and a fertilizer adding port 34 is provided in front of the stirring pump 33.

[0045] The fertilizer tank 31 of the fertilizer unit 3 can be used to place different types of fertilizers. The water inlet 32 ​​allows water to enter the fertilizer tank 31 to dilute and dissolve the fertilizer, so that the obtained liquid fertilizer can easily enter the drip irrigation unit 2. The stirring rod 37 connected to the stirring pump 33 stirs the fertilizer and water inside the fertilizer tank 31 to obtain uniform liquid fertilizer. The liquid fertilizer enters the water-fertilizer integrated machine 1 through the fertilizer outlet pipe. The fertilizer outlet pipe is provided with a filter 38 to filter the solid impurities in the liquid fertilizer to prevent the solid impurities from clogging the subsequent pipelines. Each fertilizer tank 31 is connected to the water-fertilizer integrated machine 1 through a separate fertilizer outlet pipe 39. A fertilizer outlet valve is provided between the fertilizer outlet pipe 39 and the fertilizer tank 31 to control the separate fertilizer outlet of different fertilizer tanks 31.

[0046] like Figure 3 As shown, a filter chamber 41 and a hydrothermal chamber 42 are provided at the lower portion of the heating unit 4, a water inlet three of the filter chamber 41 is connected to a water pump 48, a water outlet three of the filter chamber 41 is connected to a hydrothermal water inlet 44 of the hydrothermal chamber 42, and a hydrothermal water outlet is connected to a mixing chamber 43 above the heating unit 4, a stirring rod two is provided in the mixing chamber 43, and a heating rod 49 is provided in the hydrothermal chamber 42.

[0047] The filter chamber 41 filters the water entering the heating unit 4 to remove solid impurities such as mud and sand in the water. The water in the filter chamber 41 enters the hydrothermal chamber 42 and is heated by the heating rod 49. The hydrothermal chamber 42 is provided with a temperature sensor to monitor whether the temperature of the water in the hydrothermal chamber 42 is within the optimum temperature range required by the microorganisms. The mixing water pump 47 sends the water in the hydrothermal chamber 42 into the mixing chamber 43, and the microbial fertilizer is mixed with hot water in the mixing chamber 43. The evenly mixed fertilizer enters the drip irrigation unit 2 for drip irrigation.

[0048] A venturi aerator 45 is provided on the side wall of the mixing chamber 43 , and the venturi aerator 45 is connected to the inside of the mixing chamber 43 . The mixing chamber 43 is connected to the hydrothermal chamber 42 through a mixing water pump 47 . An exhaust valve 46 is provided on the top of the mixing chamber 43 . The second liquid outlet of the mixing chamber 43 is connected to the drip irrigation pipe 21 .

[0049] The venturi aerator 45 can provide oxygen to the microorganisms in the mixing chamber 43, and can also supply oxygen to the irrigation water entering the mixing chamber 43, so that the drip irrigation unit 2 can perform aerated drip irrigation on the plants. Aerated drip irrigation delivers oxygen to the plant roots, improves the breathing efficiency of the roots, and promotes plant growth.

[0050] Example 2

[0051] like Figure 2 As shown, the difference from Example 1 is that a heat preservation sleeve 36 is provided outside the fertilizer tank 31, and a hydrothermal interlayer 35 is provided between the heat preservation sleeve 36 and the fertilizer tank 31, and a second water inlet of the hydrothermal interlayer 35 is connected with a hydrothermal water outlet of a hydrothermal cavity 42 in the heating unit 4, and a second water outlet of the hydrothermal interlayer 35 is connected with a hydrothermal water inlet 44 of the hydrothermal cavity 42, and the second water inlet is located above the second water outlet, and the hydrothermal water inlet 44 is located above the hydrothermal water outlet.

[0052] When the fertilizer tank 31 stores microbial fertilizer, the optimum temperature range required by the microorganisms can be provided by the hydrothermal interlayer 35 and the insulation layer 24 under low temperature conditions. The hot water heated by the hydrothermal chamber 42 enters the hydrothermal interlayer 35 through the hydrothermal outlet and the second water inlet. When the hot water completely fills the hydrothermal interlayer 35, the second water outlet and the hydrothermal water inlet 44 are opened to send the hot water with reduced temperature back to the hydrothermal chamber 42 for further heating, thus completing the circulation of hot water between the hydrothermal interlayer 35 and the hydrothermal chamber 42. The insulation cover 36 is yellow, and the setting of the insulation cover 36 keeps the microbial fertilizer in the hydrothermal interlayer 35 and the fertilizer tank 31 warm.

[0053] Example 3

[0054] A method for using a water-fertilizer-gas-heat integrated drip irrigation intelligent control device in Example 2 comprises the following steps:

[0055] S1. Lay a drip irrigation pipe 21 near the plants, and determine whether the land needs to be irrigated or fertilized based on the monitoring data of the soil where the plants are planted by the temperature sensor, pH sensor, soil moisture sensor and conductivity sensor in the monitoring unit.

[0056] S2. If irrigation is needed, turn on the water inlet pump 6 to supply water to the drip irrigation unit 2 through the water-fertilizer integrated machine 1 to irrigate the plants planted in the land;

[0057] When it is necessary to heat or dissolve oxygen in the drip irrigation water, the heating rod 49 or the Venturi aerator 45 in the hydrothermal chamber 42 is turned on accordingly, and the heated or oxygenated irrigation water is delivered to the drip irrigation unit 2 to irrigate the plants. When heating, the water temperature is controlled within the range of 25-36°C, and is precisely set according to the water temperature required by different plants. As the temperature of the plant growth environment decreases, the heating temperature in the hydrothermal chamber 42 can be appropriately increased to prevent the temperature from dropping to the ambient temperature when the irrigation water reaches the farthest end during the transportation process. The maximum temperature cannot be so high as to cause the death of the nearest plant.

[0058] S3. If ordinary fertilizer is needed, the fertilizer unit 3 is connected to the water-fertilizer integrated machine 1, and the water-fertilizer integrated machine 1 sends water and fertilizer to the drip irrigation unit 2 through the heating unit 4 to fertilize the land; according to the use requirements, the heating rod or the Venturi aerator 45 is turned on to heat the fertilizer or dissolve oxygen.

[0059] S4. If microbial fertilizer needs to be applied, the fertilizer unit 3 is connected to the heating unit 4, the microbial fertilizer is adjusted to a suitable temperature in the heating unit 4, and then the microbial fertilizer is sent to the drip irrigation unit 2 to fertilize the land.

[0060] The microbial fertilizer in the fertilizer tank 31 enters the mixing chamber 43 of the heating unit 4 through the water-fertilizer integrated machine 1, and the water in the water-heat chamber 42 enters the mixing chamber 43 through the mixing water pump 47. The microbial fertilizer and the heated water are evenly mixed in the mixing chamber 43, and then enter the drip irrigation pipe 21 through the second liquid outlet, and the drip irrigation pipe 21 reaches the plants for fertilization.

[0061] S5. Determine whether to stop irrigation or fertilization again through the monitoring data of the temperature sensor, pH sensor, soil moisture sensor and conductivity sensor. The soil moisture sensor monitors the moisture in the soil, the conductivity sensor monitors the fertilizer, and the pH sensor and temperature sensor monitor the soil state to ensure that the soil is in the best state required for plant growth.

[0062] Example 4

[0063] The difference from Example 3 is that in S4, if aeration is required into the microbial fertilizer, the Venturi aerator 45 is turned on to aerate the mixing chamber 43.

[0064] Example 5

[0065] The difference from Example 3 is that in S4, when the temperature is lower than the survival temperature of the microorganisms, the water in the hydrothermal chamber 42 is sent to the hydrothermal interlayer 35 to increase the storage temperature of the microbial fertilizer in the fertilizer tank 31, and the water in the hydrothermal interlayer 35 returns to the hydrothermal chamber 42 through the hydrothermal outlet.

[0066] Example 6

[0067] The difference from the third embodiment is that the drip irrigation pipe 21 is fixed near the plants in the ground by the fixing frame 51 , and when the drip irrigation pipe 21 is connected to the drip irrigation ring 22 , the plants are planted in the center of the drip irrigation ring 22 .

[0068] When the external environment is below zero, the planted plants are irrigated under the film by drip irrigation, the drip irrigation belt is fixed in the fixing cavity 52, the upper part of the drip irrigation belt is covered with the insulation layer 24, and the insulation layer 24 is fixed to the drip irrigation pipe 21 by rotating the cover 54. The distance between the drip irrigation pipe 21 and the soil surface is adjusted by the fixing frame 51, and the ground film is supported so that it does not contact the soil surface, so as to prevent the water from freezing after drip irrigation at low temperature and freezing together with the soil through the ground film.

[0069] The drip irrigation ring 22 is threadedly connected to the branch pipe head 23 of the drip irrigation pipe 21, and then the plant is planted in the center of the drip irrigation ring 22. The branch pipe head 23 is tilted relative to the drip irrigation pipe 21 so that the drip irrigation ring 22 is in contact with the soil. The heat-insulating layer 24 is a black heat-insulating material, which absorbs heat to keep the irrigation water or fertilizer in the drip irrigation ring 22 and the drip irrigation pipe 21 warm. At the same time, the drip irrigation ring 22 can increase the soil temperature near the root system after absorbing heat, and promote the growth of plants in a low temperature environment.

[0070] Therefore, the present invention adopts a water, fertilizer, gas and heat integrated drip irrigation intelligent control device and use method of the above structure, each unit is independently set, and water, fertilizer, gas and heat are individually adjusted according to the growth needs of different plants.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
