Limit.
Can be multiple without blocking movable submersible dredge pump 5 by being uniformly arranged in wide ditch 4, it is each mobile without blocking
It is equipped with Water quality detector at proof submersible sand discharging pump 5, when some Water quality detector detects that water quality indicator is greater than first threshold, then opens
Open it is corresponding without blocking movable submersible dredge pump 5, when some Water quality detector detect water quality indicator be less than second threshold when,
It then closes and corresponding so as to preferably improve the water quality in wide ditch 4 is conducive to fish without blocking movable submersible dredge pump 5
Growth.Water quality detector includes dissolved oxygen sensor, ammonia nitrogen sensor, hydrogen sulfide sensor, nitrite sensor etc..
S3. detect the water content of 1 soil of rice field, if water content less than the second index lower limit, by mobile without blocking
Proof submersible sand discharging pump 5 draws water into pretreatment pool 2, and until water content is greater than the second index upper limit, while clear water pours pump for clear water
Whole clear water on the downside of area are evacuated in the pouring slot 6 in rice field 1, and liquid manure pours pump and extracts liquid manure into rice field 1 from fermentation zone
It pours in slot 6, clear water and liquid manure are mixed to get mixed liquor in pouring slot 6, pour after the mixed liquor in slot 6 overflows to rice field 1
It is poured.The water content detection of 1 soil of rice field can be completed by corresponding moisture teller.
Preferably, micro- floods and droughts rotation flow method further include: daily the fish into wide ditch 4 feed before feed 1 hour and/or
It feeds after feed 2 hours, by drawing water without blocking movable submersible dredge pump 5 into pretreatment pool 2, pump-out is in wide ditch 4
The 10-20% of water；Clear water pours pump and whole clear water on the downside of clear water zone is evacuated in the pouring slot 6 in rice field 1 simultaneously, liquid manure
It pours pump and extracts liquid manure in the pouring slot 6 into rice field 1 from fermentation zone, clear water is mixed to get in pouring slot 6 with liquid manure and mixes
Liquid, the mixed liquor poured in slot 6 pour rice field 1 after overflowing.
Preferably, water control is the field face 1-3cm for covering rice field 1 when pouring to rice field 1.
In the present embodiment, when being poured, rice field 1 is poured after being overflowed using the mixed liquor poured in slot 6, due to
The adjacent side contacts for pouring the both ends of slot 6 and the second side in rice field 1, so that the whole in rice field 1 can be covered to the pouring in rice field 1
Region and make the pouring to rice field 1 more uniform.
The method of the present embodiment accelerates exchanging for cultivation water and rice field 1, is conducive to being forced property of the debirs such as fish excrement
It brings rice field 1 into, is stayed in soil granular by filtering, the suction-operated of soil in rice field 1, to be conducive to these organic wastes
Object is increased the content that rice can absorb organic matter, is improved the quality of Rice Cropping soil by the microorganism decomposition in soil,
To improve the quality and yield of rice.Absorption and filtering by soil to organic waste in water are improved and are used in wide ditch 4
In the water quality for the water body breeded fish, be conducive to the growth of fish, thus the quality for increasing the yield of fish, improving fish.In addition, clearance-type is taken out
Water had not only ensured the water content of soil, has improved the water quality for water body of breeding fish, but also had saved with water, saved electricity consumption.
The method of the present embodiment to be greatly reduced in wide ditch 4 for organic waste in the water body breeded fish, the water of water body
Matter significantly improves, and the water content of soil is effectively controlled in rice field 1, has not only ensured that soil moisture content is moderate, but also protects
Hinder oxygen content in soil to fill, is conducive to the growth of rice and fish and the promotion of quality；Water is used in addition, also ing save
And electricity consumption.Experiment proves that ricefish system in this way, the speed of growth of increasing production of rice 10%, fish improves 10-
15%, the yield of fish increases 10-20%.
The above is only a preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and can be at this
In the text contemplated scope, modifications can be made through the above teachings or related fields of technology or knowledge.And those skilled in the art institute into
