Description
Technical field
The present invention relates to a kind of efficient rice field lobster mating systems, belong to lobster mating system technical field.
Background technique
Cray is also referred to as Procambius clarkii, red crayfish and freshwater crayfish, is similar to shrimp and crust is hard, and adult is about 5.6
~11.9 centimetres, kermesinus, the nearly black in crust part, belly back side has a wedge-shaped striped, and juvenile prawn body is uniform grey, sometimes
Has black ripple, chela is long and narrow, is not separated by areola in the middle part of crust, obviously has particle on crust, and volume sword has gemmule or volume
Sword end has indentation, is economic freshwater shrimps, and because meat flavour is delicious wide welcomed by the people, because of its omnivorousness, the speed of growth is fast, adapts to
Ability is strong and absolute competitive advantage is formed in local environment, range of ingesting include water plant, algae, aquatic insect,
Animal carcass etc., food are also killed each other when deficient scarce, but there are lobster low reproduction rate, shrimp seedling survival rate are low when cray cultivation
The problem of, the public problem that shrimp eats shrimp, profundal zone shrimp growing way is slow, efficiency of feed utilization is low.For this purpose, it is proposed that a kind of efficient
Rice field lobster mating system.
Summary of the invention
The main purpose of the present invention is to provide a kind of efficient rice field lobster mating systems, in normal rice shrimp aquaculture field
In again plus one of purse seine, allow shrimp phytal zone activity in purse seine, the profundal zones such as circular groove will not be entered, efficiency of feed utilization is high, small
Shrimp growing way is fast.After mating, public shrimp is all sold, and public shrimp is avoided to eat shrimp, is improved shrimp seedling survival rate, can effectively be solved to carry on the back
The problems in scape technology.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of efficient rice field lobster mating system, includes the following steps:
1) launch parent shrimp: early August puts 60 pounds/acre of seed shrimp；
2) circular groove precipitation position: receiving the paddy previous moon, water stratification in circular groove reduced, and promotion lobster burrows to mate and breed；
3) circular groove cleans: receiving and is cleaned when having a small amount of water in the front/rear circular groove of paddy using tea cake；
4) receive paddy: rice stubble stays 35~50 centimeters when receiving paddy, and rotary tillage intercroping, rotary tillage width is 2 meters, and 8- is divided between rotary tillage
10 meters, the rice straw compost in rice field；
5) shine the pool: the pool needs to shine 10~15 days after the completion of receiving paddy, can be cleaned up the pond with quick lime during shining the pool；
6) it encloses anti-escape network: shining the pool and add one of anti-escape network in rice field surrounding later；
7) go up water for the first time: the solarization pool is cleaned up the pond after the completion of purse seine, for the first time upper 10 centimeters of the super platform of water；
8) feed: circular groove gradually starts to feed after upper water；
9) water plant kind grass: is planted in the rice field of purse seine；
10) secondary plus water: after water plant length is got up, water level is slowly promoted to required water level；
11) it shifts parent shrimp: female shrimp in circular groove being started to launch in the purse seine in rice field, public shrimp is directly sold.
Further, the male and female ratio of the seed shrimp is 1:2.
Further, it is layering precipitation when water level reduces, reduces water level 10-20 centimeters every time.
Further, November started to March in the coming year, every month rich water twice, replenish the calcium twice.
Further, a little bacillus can be added when the rice straw compost received in paddy step, promote to decompose.
Further, the amount of the quick lime used when cleaning up the pond is 120 pounds/acre.
Further, the surrounding in purse seine rice field in circular groove.
Further, the water plant is waterweed.
The present invention encloses anti-escape network in rice shrimp field, makes shrimp phytal zone in purse seine movable, will not enter the deep water such as circular groove
Area, efficiency of feed utilization is high, and shrimp growing way is fast, and after mating, public shrimp is all sold, and public shrimp is avoided to eat shrimp, artificial screening
In female shrimp investment rice shrimp field purse seine, best shrimp seedling living environment is built, his natural enemy is controlled, improves shrimp seedling survival rate.
Detailed description of the invention
Fig. 1 is the shooting figure on the spot in rice shrimp of the present invention field.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in Figure 1, including the following steps: the present embodiment provides a kind of efficient rice field lobster mating system
1) launch parent shrimp: early August puts 60 pounds/acre of seed shrimp；
2) circular groove precipitation position: receiving the paddy previous moon, water stratification in circular groove reduced, and promotion lobster burrows to mate and breed；
3) circular groove cleans: receiving and is cleaned when having a small amount of water in the front/rear circular groove of paddy using tea seed cake；
4) receive paddy: rice stubble stays 35~50 centimeters when receiving paddy, and rotary tillage intercroping, rotary tillage width is 2 meters, and 8- is divided between rotary tillage
10 meters, the rice straw compost in rice field；
5) shine the pool: the pool needs to shine 10~15 days after the completion of receiving paddy, can be cleaned up the pond with quick lime during shining the pool；
6) it encloses anti-escape network: shining the pool and add one of anti-escape network in rice field surrounding later；
7) go up water for the first time: the solarization pool is cleaned up the pond after the completion of purse seine, for the first time upper 10 centimeters of the super platform of water；
8) feed: circular groove gradually starts to feed after upper water；
9) water plant kind grass: is planted in the rice field of purse seine；
10) secondary plus water: after water plant length is got up, water level is slowly promoted to required water level；
11) it shifts parent shrimp: female shrimp in circular groove being started to launch in the purse seine in rice field, public shrimp is directly sold.
Further, the male and female ratio of the seed shrimp is 1:2.
Further, it is layering precipitation when water level reduces, reduces water level 10-20 centimeters every time.
Further, November started to March in the coming year, every month rich water twice, replenish the calcium twice.
Further, a little bacillus can be added when the rice straw compost received in paddy step, promote to decompose.
