Problems solved by technology

At present, due to the low content of dissolved oxygen in the water body itself, and the high temperature weather also causes the oxygen content in the water body to decrease, in order to ensure the oxygen content in the water body, the traditional method is to continuously inject new water sources and increase aerator 4 equipment, but Injecting new water sources, especially during fertilization and pesticide spraying, will cause the loss of fertilizers and pesticides. Although the aerator 4 is effective, the large area of ​​farmland requires a lot of aeration equipment, and because the water level in the farmland is very shallow (too high water level will cause the seedlings to drown), a large number of oxygen bubbles will escape the water surface, the dissolved oxygen efficiency is still very low, and the cultivation cost is too high

Embodiment 1

[0102] The device for irrigating rice crops with micro-oxygen bubble magnetized water of the present embodiment, see image 3 , comprising a microbubble cavitation pipe and a circulating water pump 5, a circulating water pipe 2, and an aerator 4, one end of the circulating water pipe 2 communicates with the waterway outlet of the paddy field 1 through the circulating water pump 5, and the other end of the circulating water pipe 2 passes through the microbubble cavitation The pipe is connected with the waterway entrance of the rice field 1, so that the rice field 1 and the circulating water pipe 2 form a waterway circulation, and realize the recycling of irrigation water. The end of the circulating water pipe 2 connected to the micro-bubble cavitation pipe is also communicated with the aerator 4 through a pipeline, and oxygen is filled into the inflow water of the micro-bubble cavitation pipe. In order to increase the treatment capacity of irrigation water, a plurality of micro...

Embodiment 2

[0114] The difference from Embodiment 1 is that in this embodiment, a cylindrical split fluid 33 with a radius of 2mm is provided in each diffusion groove 31, so that the fluid in the diffusion groove 31 is divided and then diffused in multiple stages.

[0115] When i=1,3,5, the center coordinates of the sub-body 33 are (x i ,y qi ):

[0116]

[0117] the y qi =L / 2-1

[0118] When i is 2,4, the center coordinates of the sub-body 33 are (x i ,y qi ):

[0119]

[0120] the y qi =L / 2+1.

[0121] Other components are the same as in Embodiment 1.

Embodiment 3

[0123] The device for irrigating rice crops with micro-oxygen bubble magnetized water includes a micro-bubble cavitation pipe, a circulating water pump 5, an aeration pump, and a circulating water pipe 2, and one end of the circulating water pipe 2 communicates with the waterway outlet of the paddy field 1 through the circulating water pump 5. The other end of the circulating water pipe 2 communicates with the waterway inlet of the paddy field 1 through the sequentially connected aeration pump and microbubble cavitation pipe, so that the paddy field 1 and the circulating water pipe 2 form a waterway circulation to realize the recycling of irrigation water.

[0124] In order to increase the treatment capacity of irrigation water, a plurality of micro-bubble cavitation tanks 3 are arranged side by side in the micro-bubble cavitation tube, and the micro-bubble cavitation tanks 3 are arranged up and down in the micro-bubble cavitation tube. A tank cover is installed on the top of t...

Abstract

The invention proposes a device for irrigating rice crops with magnetized water with micro-oxygen bubbles and a method for irrigating rice crops with magnetized water with micro-oxygen bubbles, which belong to the technical field of crop irrigation; The micro-bubble cavitation pipe is set, the micro-bubble cavitation tank is arranged behind the pipe, the micro-bubble cavitation pipe is connected with the aerator, and the cooperation of the three can realize increasing the oxygen content of the irrigation water; the method for irrigating rice crops includes diversion and In the process of diffusion oxygenation, ordinary irrigation water is enriched with oxygen through diffusion oxygenation, and the dissolution rate of fertilizer in irrigation water is enhanced through magnetization; this irrigation device and irrigation method can solve the problem of promoting oxygen supplementation of rice roots and effectively preventing rice roots from rotting. And improve the utilization rate of nutrients in chemical fertilizers.

Description

technical field [0001] The invention belongs to the technical field of rice crop irrigation, and in particular relates to a device and a method for irrigating rice crops with micro-oxygen bubble magnetized water. [0002] technical background [0003] Rice is the largest food crop in China. For a long time, the total area, total output and output per unit area of ​​rice have ranked first in the country's food crops. Therefore, rice production has always been of pivotal strategic significance in China's grain production and agricultural development. Rice is one of the most important food crops in China, and rice is the staple food of more than 60% of the population. As China's arable land area is getting smaller and smaller, continuously increasing rice yield will be the most effective way to meet the growing food demand and ensure national food security. If rice production can increase substantially, China's food problem can be easily solved. However, there are many factor...
