Embodiment
Below in conjunction with specific embodiment, the utility model is further described.
The half crop rotation cultivating system of embodiment 1 one kinds of Tilapia mossambica-grass carps
As shown in Figure 1, the half crop rotation cultivating system of a kind of Tilapia mossambica-grass carp, there are two mouthfuls of ponds, be respectively seed rearing pond 1 and marketable fish cultivating pool 2, hybrid giant napier culture zone 3 is had between seed rearing pond 1 and marketable fish cultivating pool 2, the degree of depth in seed rearing pond 1 is 1.5-2.0 rice, four angles in seed rearing pond 1 are provided with 4 impeller automatic aerators 4, the degree of depth that pond 2 cultivated by marketable fish is 2.0-2.5 rice, four angles of marketable fish cultivating pool 2 are provided with 4 impeller automatic aerators 4, the bottom in seed rearing pond 1 is also provided with mud discharge line 5 at the bottom of the pool, at the bottom of this pool, mud discharge line 5 is connected with hybrid giant napier culture zone 3, the bottom of marketable fish cultivating pool 2 is also provided with mud discharge line 5 at the bottom of the pool, mud discharge line 5 and hybrid giant napier at the bottom of this pool cultivate 3rd district and are connected, at the bottom of the pool in two ponds, the both sides of mud discharge line 5 are provided with pump 6, for extracting mud at the bottom of the pool, breeding is cultivated in pond 1 and marketable fish cultivating pool 2 and is provided with drainage pipeline 7, drainage pipeline 7 in two ponds is all connected with sewage collection system 8, the both sides of the drainage pipeline 7 in two ponds are all provided with suction pump 9.
The using method of the system of embodiment 2 embodiment 1
The concrete using method of the half crop rotation cultivating system of the Tilapia mossambica-grass carp of embodiment 1 is as follows:
May is the Tilapia mossambica seed of 1-2cm to stocking size in seed rearing pond, breeding density is 2000-3000 tail/mu, tilapia feed is adopted to feed, cultivation is to July, when Tilapia mossambica probably grows to 1-2 two, Tilapia mossambica is transferred to marketable fish cultivating pool to cultivate, in marketable fish cultivating pool, the breeding density of Tilapia mossambica is 1200-2300 tail/mu, cultivate the June to Second Year, in marketable fish cultivating pool, the breeding way of Tilapia mossambica is: the filter food considering Tilapia mossambica and the feature of ingesting, to throw something and feed tilapia feed, the bloom starting to throw something and feed through commercially available EM bacterium fermentation of marketable fish cultivating pool is such as transferred to Tilapia mossambica, the low albumen tilapia feed such as wheat bran or any commercial protein quality percentage are the low albumen tilapia feed of 15%-25%, this Low protein diet can slow down the growth of fish, improve the anti-stress ability of fish, it's the popular outbreak of disease phase pasts degree of safety, and not easily infect saprolegniasis because of frostbite when surviving the winter, effective guarantee Tilapia mossambica safe overwintering survival rate, when low albumen tilapia feed of throwing something and feeding throws something and feeds Tilapia mossambica cultivation Second Year March, Tilapia mossambica probably grows to the scale of 3-5 two, albumen quality of now throwing something and feeding percentage is that the high-quality generation of 28-35% sells tilapia feed, can sell to Tilapia mossambica in June, wherein, in marketable fish cultivating pool Tilapia mossambica breeding process in, optionally can regulate and control water quality by modes such as rich water.
On the other hand, after Tilapia mossambica is migrated out from seed rearing pond, carry out wet method to seed rearing pond to clean up the pond, be specially and adopt the suction pump in seed rearing pond and pumping system that water is drawn to sewage collection system, then adopt mud discharge line and corresponding pump at the bottom of the pool of seed rearing pond bottom that the mud at the bottom of the pool is drawn to hybrid giant napier culture zone.
After cleaning up the pond, grass carp after being 25-35 gram of immunity from August to stocking size in seed rearing pond, breeding density is 1400-2000 tail/mu, the hybrid giant napier of hybrid giant napier culture zone cultivation is adopted to throw something and feed grass carp, if hybrid giant napier is not enough, commercially available grass carp artificial feed of throwing something and feeding can be supplemented, to the grass carp cultivation in seed rearing pond to Second Year April, grass carp probably grows to 0.7-1.5 jin, selection specification is that the grass carp of 1.0-1.2 jin specification is transferred to marketable fish cultivating pool, in marketable fish cultivating pool, the breeding density of grass carp is 300-400 tail/mu, the cultivation of the grass carp in marketable fish cultivating pool adopts the hybrid giant napier of hybrid giant napier planting area to throw something and feed, to throw something and feed when hybrid giant napier is not enough the commercially available artificial feed of grass carp, during to June, the growth specification of grass carp probably can reach 1.8-2.5 jin, can sell.
On the other hand, the Grass carp direct marketing below the grass carp more than 1.2 jin of specifications in all the other seed rearing ponds or 1.0 jin of specifications.After treating the grass carp sale for sale in seed rearing pond, repeat again above-mentionedly to carry out cleaning up the pond after method that wet method cleans up the pond carries out draining to seed rearing pond, be ready to so that May time second when taking turns cultivation again stocking size be the Tilapia mossambica seed of 1-2cm.
The using method of the present embodiment is adopted to carry out the half crop rotation cultivation of Tilapia mossambica-grass carp, Tilapia mossambica product safety can be ensured, the availability in effective raising pond and culture benefit, the hybrid giant napier of hybrid giant napier growing area is that grass carp provides natural bait, hybrid giant napier plantation is planted as nutrient by the mud in pond, can reduce the impact of mud on fisheries environment.
Half crop rotation cultivating system and the using method of embodiment 3 one kinds of Tilapia mossambica-grass carps
Half crop rotation cultivating system of this embodiment and half crop rotation cultivating system of embodiment 1 basically identical, difference is: the area in seed rearing pond 1 is 5.5 mu, the area of marketable fish cultivating pool 2 is 8.0 mu, does not arrange drainage pipeline and suction pump in seed rearing pond 1 and marketable fish cultivating pool 2.
The using method of this half crop rotation systems is different from embodiment 2 to be, the desilting of seed rearing pond and marketable fish cultivating pool adopts dry method desilting but not wet method desilting, be specially and first shine the pool, adopt mud discharge line at the bottom of the pool that mud at the bottom of the pool is expelled to hybrid giant napier culture zone again after shining the pool, both preparation of ponds is clean, again using the fertilizer that mud cultivates as hybrid giant napier, energy-saving and environmental protecting.
Embodiment 4 compliance test result experimental example
The system of embodiment 1 and the using method of embodiment 2 is adopted to carry out culture efficiency demonstration test.In Shaoguan region, North Guangdong.
Cultivation result is: in May, 2013, and drop into Tilapia mossambica seed 16.5 ten thousand tail altogether, Tilapia mossambica average weight is 55 grams; Drop into grass carp 110,000 tail after 25-35 gram of immunity altogether.In June, 2014, gather in the crops Tilapia mossambica 13.6 ten thousand jin altogether, 7.9 ten thousand jin, grass carp, other trash fish 0.45 ten thousand jin, in addition, the grass carp also remaining more than 1.2 jin specifications in seed rearing pond is not transferred to marketable fish cultivating pool, totally 4650 jin, the grass carp of this part specification, be not transferred in marketable fish cultivating pool, direct marketing, achieve good cultured output and economic benefit.
The above; be only preferably specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and design thereof and replace or change, all should be encompassed in protection domain of the present utility model.
