Detailed implementation manners

[0018] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0019] Embodiment 1 As Figures 1-3 shown, a high-efficiency organic water and fertilizer integration system includes a water supply module 1, a fertilizer supply module 2, a gas supply module 3 and a plurality of irrigation modules 4. The plurality of irrigation modules 4 are respectively installed in different planting areas. The water supply module 1 and the fertilizer supply module 2 are used to convey irrigation water and fertilizers to the irrigation module 4, and the gas supply module 3 is used to provide water outlet pressure to the irrigation module 4.

[0020] As Figure 1 shown, the water supply module 1 includes a water storage tank 11 and a water supply pump 12. The water storage tank 11 is used to store the irrigation water that has been subjected to secondary filtration treatment by a sand filter and a disc filter to filter out particulate impurities in the irrigation water and avoid clogging of the irrigation module 4. A plurality of irrigation modules 4 are connected to the water storage tank 11 through the main pipeline 13, and the water supply pump 12 is installed on the main pipeline 13 and is used to pump the irrigation water to the irrigation module 4.

[0021] As Figure 1 、 Figure 2 shown, the fertilizer supply module 2 includes a fertilizer supply pump 21 and three fertilizer tanks 22. High-nitrogen liquid organic fertilizer, high-phosphorus liquid organic fertilizer and high-potassium liquid organic fertilizer are respectively placed in the three fertilizer tanks 22. The three fertilizer tanks 22 are all connected to the main pipeline 13 through the fertilizer supply pipeline 23, and the fertilizer supply pump 21 is installed on the fertilizer supply pipeline 23 and is used to pump the organic fertilizer in the fertilizer tank 22 into the main pipeline 13.

[0022] Among them, the high-nitrogen liquid organic fertilizer is prepared by fermenting soybean meal, fish protein, kitchen waste, urine, algae, etc., which can promote leaf growth and is suitable for leafy vegetables or crops with a large nitrogen demand during the growth period. The high-phosphorus liquid organic fertilizer is made by decomposing bone meal with acetic acid or lactic acid bacteria from bone meal, fish bones, etc., and has the function of promoting root development and flowering and fruiting, and is suitable for fruit and flower crops. The high-potassium liquid organic fertilizer is prepared from leachate of plant ash, banana peel, bagasse, wood vinegar, etc., and has the effect of enhancing stress resistance and promoting fruit enlargement, and is suitable for crops during the fruiting period.

[0023] As Figure 2 shown, the fertilizer tank 22 includes a tank body 221, a stirring motor 222 and a stirring shaft 223. The tank body 221 is made of plastic. A feeding port 2211 is opened at the top of the tank body 221 for feeding liquid organic fertilizer into the tank body 221. A fertilizer discharging port 2212 is opened on the side of the bottom of the tank body 221, and a fertilizer discharging valve 2213 is installed at the fertilizer discharging port 2212. The fertilizer discharging valve 2213 is an electromagnetic valve for controlling the opening and closing of the fertilizer discharging port 2212. The fertilizer discharging valve 2213 and the fertilizer supply pump 21 work together to control the fertilizer discharging amount of different fertilizer tanks 22. That is, when the fertilizer supply pump 21 is turned on, the fertilizer discharging valves 2213 of the three fertilizer tanks 22 are opened for different set durations respectively to pump different proportions of fertilizers according to needs. Preferably, the fertilizer discharging valve 2213 is installed near the fertilizer supply pump 21 to avoid the residual fertilizer in the pipeline affecting the accuracy of fertilizer ratio.

[0024] As Figure 2 shown, the stirring motor 222 is installed at the center of the top of the tank body 221. The output shaft of the stirring motor 222 is installed vertically downward. The stirring shaft 223 is vertically installed on the output shaft of the stirring motor 222, and the lower end of the stirring shaft 223 extends into the bottom of the tank body 221. Two stirring blades 224 are installed on the stirring shaft 223. When the stirring motor 222 rotates, the stirring shaft 223 drives the two stirring blades 224 to rotate to realize the stirring and mixing of the liquid organic fertilizer.

The top of the grinding block 226 is provided with a conical guiding surface, and the edge of the guiding surface is lower than the edge of the grinding groove, so as to form a receiving groove between the grinding block 226 and the grinding seat 225. During use, the liquid organic fertilizer is put into the receiving groove from the feeding port 2211. The liquid in the liquid organic fertilizer directly flows through the gap between the grinding block 226 and the grinding seat 225 into the tank body 221. The insoluble impurities in the liquid organic fertilizer flow into the tank body 221 after being ground by the grinding block 226 and the grinding seat 225, so as to reduce the particle size of the insoluble impurities in the liquid organic fertilizer and avoid clogging of the irrigation module 4. When putting solid soluble organic fertilizer, the grinding block 226 and the grinding seat 225 can also crush the solid particles to improve the dissolution efficiency of the solid soluble organic fertilizer.

The air compressor is used to provide high-pressure air to the irrigation module 4; the ozone generator is used to disinfect the irrigation module 4 to avoid the formation of a bacterial layer in the irrigation module 4 and cause clogging of the irrigation module 4. When growing crops in a greenhouse, the gas generation device can also be equipped with an oxygen generator, a hydrogen generator, and a carbon dioxide generator to provide gas fertilizers for the crops.

[0027] As Figure 1 、 Figure 3 shown, the irrigation module 4 includes a pressure tank 41 and an irrigation pipeline 42. The pressure tank 41 is a fiberglass tank body. The lower part of the side of the pressure tank 41 is respectively provided with a water inlet 411, a water outlet 412, and an air inlet 413. The top of the pressure tank 41 is provided with an exhaust port 414.

[0028] As Figure 1 、 Figure 3 shown, the water inlet 411 is connected to the main pipeline 13. An inlet valve 415 is installed between the water inlet 411 of each pressure tank 41 and the main pipeline 13. The water supply module 1 is connected to the pressure tank 41 through the main pipeline 13 and is used to transport irrigation water to the pressure tank 41. The fertilizer supply module 3 is communicated with the main pipeline 13 and is used to synchronously transport fertilizers into the pressure tank 41. The inlet valve 415 is an electromagnetic valve and is used to control the water inlet of each pressure tank 41.

[0029] As Figure 1 、 Figure 3As shown, the air inlet 413 is connected to the air supply module 3 through the air delivery pipe 32. An air inlet valve 416 is installed between the air inlet 413 of each pressure tank 41 and the air delivery pipe 32. The air inlet valve 416 is an electromagnetic valve, which is used to control the air intake of each pressure tank 41. An aeration mechanism 43 is installed in the pressure tank 41.

[0030] As Figure 1 , Figure 3 shown, the water outlet 412 of the pressure tank 41 is connected to the irrigation pipeline 42 through a branch pipeline, and a water outlet valve 417 is installed between the water outlet 412 and the irrigation pipeline 42. The irrigation pipeline 42 is one or more of a drip irrigation pipe, a drip irrigation tape, a ground-inserted micro-sprinkler, a rocker nozzle or an inverted micro-sprinkler. The water outlet valve 417 is an electromagnetic valve, and the water outlet valve 417 is used to control the drainage of the pressure tank 41.

The water supply module 1 and the fertilizer supply module 2 transport irrigation water and fertilizer into the pressure tank 41 through the main pipeline 13.

[0032] When watering, the water inlet valve 415 and the exhaust valve 418 are both in the closed state, and the water outlet valve 417 and the air inlet valve 416 are both in the open state. The air supply module 3 transports high-pressure gas into the pressure tank 41 through the air delivery pipe 32, presses out the water-fertilizer mixture in the pressure tank 41, and transports it to the crops through the irrigation pipeline 42.
