Problems solved by technology

At present, when farmers soak rice seeds, they generally put the seeds in plastic bags, tie the bag tightly, and soak them in water. Because the dissolved oxygen concentration in the water is very low, a large number of seeds accumulate together, which will cause Rice seeds are hypoxic during the germination process, and the soaked seeds produce less energy during anaerobic respiration, which cannot meet the needs of life activities. At the same time, the alcohol produced has a toxic effect on cells, which will cause the seed germination process to be blocked or even die. To avoid Too many seeds die, generally adopt common aerator 5 to inject oxygen to the water body, although it has been improved, but due to the large volume of oxygen bubbles, a large number of oxygen bubbles will escape the water body, and cannot fundamentally solve the problem of insufficient dissolved oxygen in the water body situation

Embodiment 1

[0079] The micro-oxygen bubble paddy rice oxygen-enriched breeding device of the present embodiment, see figure 1 , comprising a breeding device 1, a microbubble cavitation tube, an aerator 5, a circulating water pump 4, and an ultrasonic transducer 2, wherein the breeding device 1 adopts a water inlet method of bottom in and top out, and a water inlet is provided at the bottom thereof, There is a water outlet on the upper side wall. The body of the breeding device 1 is an ordinary conventional glass cylinder or ceramic tank or plastic cylinder. The water inlet end of the pipe communicates with the water outlet on the upper side wall of the breeding device 1 through the circulating water pump 4 installed on the circulating water pipeline, so as to realize the breeding water circulation. The water inlet end of the micro-bubble cavitation pipe is also connected with the aerator 5 through a pipeline, and the micro-bubble treatment is first supplemented with oxygen in the breeding...

Embodiment 2

[0091] 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, see figure 2 , the fluid in the diffusion tank 31 is split and then diffused in multiple stages.

[0092] When i=1,3,5, the center coordinates of the sub-body 33 are (x i ,y qi ):

[0093]

[0094] yy iqi =L / 2-1

[0095] When i is 2,4, the center coordinates of the sub-body 33 are (xi ,y qi ):

[0096]

[0097] yy iqi =L / 2+1.

[0098] Other components are the same as in Embodiment 1.

Embodiment 3

[0100] The micro-oxygen bubble paddy oxygen-enriched breeding device of the present embodiment comprises a breeding device 1, a micro-bubble cavitation tube, an aerator 5, a circulating water pump 4 and an ultrasonic transducer 2, wherein the breeding device 1 adopts a bottom-in and top-out The water inlet mode is provided with a water inlet at the bottom and a water outlet on the upper side wall. The body of the breeding device 1 is a common conventional glass cylinder or ceramic tank or plastic cylinder. The water outlet end of the cavitation pipe is connected, and the water inlet end of the microbubble cavitation pipe is connected with the water outlet on the upper side wall of the breeding device 1 through the circulating water pump 4 installed on the circulating water pipeline, so as to realize the breeding water circulation. The water inlet end of the micro-bubble cavitation pipe is also connected with the aerator 5 through a pipeline, and the micro-bubble treatment is fi...

Abstract

The invention provides an oxygen-enriched breeding device and an oxygen-enriched breeding method for micro-oxygen bubble rice and relates to the technical field of oxygen-enriched breeding of rice. The breeding device comprises a breeder, wherein a micro-bubble cavitation pipe is arranged at a water inlet in the bottom of the breeder; and at least two micro-bubble cavitation tanks are arranged inthe micro-bubble cavitation pipe. The oxygen-enriched breeding method for micro-oxygen bubble rice comprises processes of shunt, diffusion and oxygen enrichment. According to the oxygen-enriched breeding device and the oxygen-enriched breeding method for micro-oxygen bubble rice disclosed by the invention, the breeding water is subjected to micro-oxygen bubble treatment, the dissolved oxygen in water is increased, germination of seed rice and growth of the root system are met, and the germination rate and survival rate of oxygen-enriched breeding of the rice are improved.

Description

technical field [0001] The invention belongs to the technical field of crop oxygen-enriched breeding processing equipment, and in particular relates to an oxygen-enriched breeding device and an oxygen-enriched breeding method for rice with micro-oxygen bubbles. technical background [0002] 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. If rice production can increase substantially, China's food problem can be easily solved. The quality of rice seeds is the internal germination ability of seeds, and its quality is one of the main technical indicators of whether rice production is increased. The quality of rice seed germination is the result of the interaction between internal factors of seeds and the environment. Excluding...
