The method is characterized in that according to the aquatic plant cultivation step, elodea nuttallii and hydrilla varticillata undergo point-shaped cultivation in a pond in March every year, the cultivation point distance is 80-100 cm, alternanthera philoxeroides is transplanted into the pond when the water surface coverage rate of elodea nuttallii in the pond is reduced to below 20%, and the water surface coverage rate of alternanthera philoxeroides in the pond is not larger than 20%; and the aquatic plant coverage rate in the pond reaches 60-65%. The method is simple to implement, larval crabs are low in precocious rate, a good survival environment is created for growth of the larval crabs, it is guaranteed that the larval crabs are robust, the shell capacity is enhanced, and a foundation is laid for high and stable yield of the larval crabs.
Description
Technical field
The present invention relates to the cultural method of crab, particularly relate to a kind of button Eriocheir sinensis and cultivate water body Dissolved oxygen regulation method.
Background technology
Eriocheir sinensis is also known as crab, eriocheir sinensis, clear water Eriocheir sinensis, steamed crab or Eriocheir sinensis, delicious flavour, and nutrition is rich
Richness, is a kind of economic crab, is one of the famous and precious aquatic products of Chinese tradition.Crab is as the traditional water of China
Produce treasure, along with exhaustion and the expansion of the market demand, artificial breeding and the aquaculture of its wild resource obtain
Fast development, the whole nation culture of Chinese mitten crab industry output value alreadys more than 20,000,000,000 yuan at present, it has also become China's aquaculture
An important component part in industry.Its higher economic benefit, has attracted substantial amounts of agriculture, fisherman to participate in supporting
Grow, along with the industry size of China's culture of Chinese mitten crab industry constantly expands, the production of high-quality top grade ChangJiang River crab
Technology increasingly becomes the key technology that crab industry development is badly in need of, and it is the key in crab industry that button Eriocheir sinensis is cultivated
One of link, for cultivating high-quality button Eriocheir sinensis, on the premise of juvenile crab quality guarantees, Applied Physics means tuning is numerous
Educate water body dissolved oxygen, make water body dissolved oxygen normal >=5.5mg/L, create best living environment for button Eriocheir sinensis growth so that it is
The positive effect of its cultivating condition is farthest played, it is ensured that button Eriocheir sinensis body constitution is healthy and strong, and shell ability increases
By force, for realize crab high and stable yields lay the foundation.
Summary of the invention
It is an object of the invention to provide a kind of button Eriocheir sinensis and cultivate water body Dissolved oxygen regulation method, the method is implemented simple,

Ability strengthens, and lays the foundation for realizing crab high and stable yields.
The present invention is achieved through the following technical solutions:
A kind of button Eriocheir sinensis cultivates water body Dissolved oxygen regulation method, and including pasture and water cultivation and pond dissolved oxygen step, it is special
Levy and be: described pasture and water cultivation step: pond point-like in March cultivation waterweed and hydrilla verticillata every year, plant
Training dot spacing 80-100cm, in waterweed pond, water surface coverage rate transplants water peanut when dropping to less than 20%
Entering pond, in pond, water peanut water surface coverage rate is not more than 20%；In pond, pasture and water coverage rate reaches 60%-65%.
In described waterweed and hydrilla verticillata pond, water surface coverage rate dynamic optimization is: April is to JIUYUE waterweed
Reaching 60%-65% with water surface coverage rate in hydrilla verticillata pond, wherein in waterweed pond, water surface coverage rate reaches
In 20%-40%, hydrilla verticillata pond, water surface coverage rate reaches 20%-40%.
Cutting off the perishable part in waterweed upper end in time, the length of waterweed maintains 20～40cm and does not reveals
Go out the water surface.
Described pond dissolved oxygen step: arranging micro-pore oxygenation equipment in pond, aeration tube is distributed in gas pipeline
Both sides and being vertically set in pond, it is achieved water body upper, middle and lower oxygen supplement simultaneously, it is ensured that dissolved oxygen is more equal
Even, integrated physical method regulation and control button Eriocheir sinensis cultivates water body dissolved oxygen so that it is normal >=5.5mg/L.
Arranging intelligent monitor system, intelligent monitor system is to change in values such as pond water temperature, dissolved oxygen, pH value
Situation realizes on-line monitoring, can send out when dissolved oxygen, pH value, nitrite equal size are below or above setting value
Go out warning, automatically switch oxygen increasing equipment, it is achieved precisely operate.
The present invention improves pond waterweed and hydrilla verticillata Planting pattern, waterweed and hydrilla verticillata are planted by band
Training changes point-like cultivation into, cultivates dot spacing 80-100cm, and its coverage rate respectively accounts for the 20% of the water surface.Mid-April
To the growth of late June waterweed quickly, its water surface coating ratio is stepped up to 40% by 20%；On July
Ten days to late September waterweed water surface coating ratio is progressively fallen back to less than 20% by 40%；Waterweed growth is fast,
Pasture and water gap is closeer, will cut off the perishable part in waterweed upper end in time, it is ensured that the length of waterweed grass maintains
Do not surface 20～40cm；After waterweed falls back to less than 20%, transplant water peanut and enter pond.4
The growth of the middle of the month to late June hydrilla verticillata is slow, and its water surface coating ratio is stepped up to 25% by 20%；
Early July to late September hydrilla verticillata water surface coating ratio is risen to more than 40% by 25%；In pond four
Week excavates circular groove and forms the hollow pool, hydrilla verticillata shallow water plantation in early days, and hydrilla verticillata growth is late, high temperature resistant,
Pasture and water gap is big, high temperature ventilating duct to be cleared out of, it is ensured that the air permeability of water body.
The present invention compared with prior art has the advantages that
1, the present invention can stably detain Eriocheir sinensis water body dissolved oxygen, restriction button Eriocheir sinensis sexual precosity, improves button Eriocheir sinensis and puts in a suitable place to breed close
Degree, improves yield per unit area.
2, the present invention uses physical method, does not use any chemical substance, does not has any negative shadow to environment
Ring.
3, the cultivation of button Eriocheir sinensis is one of key link in crab industry, for cultivating high-quality button Eriocheir sinensis, in juvenile crab matter
On the premise of amount guarantees, Applied Physics means tuning breeds water body dissolved oxygen, make water body dissolved oxygen normal >=5.5mg/L,
The present invention can create best living environment for button Eriocheir sinensis growth so that it is the positive effect of its cultivating condition obtains
The performance of big degree, it is ensured that button Eriocheir sinensis body constitution is healthy and strong, and shell ability strengthens, establishes for realizing crab high and stable yields
