Description

River crab master supports the ecological prevention method of pond moss
Technical field
The invention belongs to cultural technique fields, and in particular to river crab master supports the ecological prevention method of pond moss.
Background technology
Moss in cultivating pool is mostly occurred after spring weather turns warm, and temperature goes back up to 10 DEG C or more, and moss is in pond Shoal starts flourish, bottom of pond of growing nonparasitically upon another plant as hair in early days, in the upright water in upper end.With the raising of temperature, moss is just Mass propagation forms sleave round and round as net hangs in Zhang Yushui when serious.Dialysis bottom of pond when aging, becoming cotton-wool will float In the water surface, color is in yellow green, and feel is satiny.
With temperature, the raising of water temperature, less serious case, a large amount of mosses are attached to the cultivated animals body surface such as crab species, are often twined and are dragged It in it, influences it and looks for food, the cultivated animals such as river crab is caused to ingest reduction, it is slow-growing, and then growth and commodity value are influenced, Make the reduction of pond culture economic benefit.Severe one, moss are risen death in pond, by wind to Chi Jiao or are sunk to the bottom blackening, are given out One foul smell.It is also easy to produce the pernicious gases such as hydrogen sulfide in decomposable process, improves ammonia-nitrogen content in pond, reduces in water Dissolved oxygen content causes pond anoxic, and the aquiculture animals such as crab species is caused to be poisoned to death, and cultivation survival rate reduces.
A large amount of sleave floating in water, hinders the raising of water temperature and the dissolving of oxygen and largely consumes the inorganic salts in water The nutrients such as class make normal nutrient metabolism in crab pond be destroyed, and water fertilizer does not get up, and water reduces, and influences in pond The absorption of the benthic growth such as spiral shell and planktonic organism to luminous energy, makes planktonic organism in cultivating pool reduce.When serious The growth for having an effect on water plant causes water plant aging dead, is easy to ruin water quality.
Currently, preventing aquaculture pond there is the measure of moss：After annual aquaculture product has harvested, water is drained, with pushing away Native machine cuts out surface layer mud, and pond is cleared and sterilized；Spring receive liquid manure pond when, regard the water fertilizer degree rational application of fertilizer, receiving water can not be shallow, fertilizer It dissolves, full pool spilling head is uniform, and fertilizer is avoided to sink to the bottom.Occurs the processing method after moss in aquaculture pond：When aquaculture pond not When putting aquatic products seedling in a suitable place to breed and a large amount of mosses occur, the water surface will sprinkle several kilograms of quick limes and kill moss per acre, then drain pond Water, again Na Shuifeichi.When aquaculture pond has put aquatic products seedling in a suitable place to breed and a small amount of moss occurred, water water level is raised as far as possible, it is numerous Micro Algae is grown, water is made to grow fat, inhibits moss breeding.When pond has put aquatic products seedling and moss mass propagation in pond in a suitable place to breed, The drugs such as prometryn, moss net, copper sulphate, penta sodium pentachlorophenate are used to remove.However copper sulphate uses excessively, it is easy to generate medicine Evil if usage amount is few, and does not work；Prometryn is unknown to the aquiculture animal mechanism of action, has been forbidden to use.In addition, Motor-driven foot also can be used and generate turbid wave in pond, or yellow mud of splashing, pool water is made to become muddy, reduce water transparence, suppression Moss growth processed, and manually skimmed using the tools such as pole or special rake, net fishing, it is big to there is hand labor intensity in this way.
Invention content
It is endangered for existing for above-mentioned moss, the present invention provides a kind of ecological prevention method of the foster pond moss of river crab master, should Method can effectively control the quantity of moss in water body, prevent the deterioration for leading to water quality because of alga eruption.
River crab master of the present invention supports the ecological prevention method of pond moss, includes the following steps：
1）After cultivation fishing, drains water and clean up the pond, so that pool bottom is exposed to the sun under sunlight, be exposed to the sun the time About 45-50 days；After being exposed to the sun, sprayed with the aqueous solution of bur celery extract, splash again after 2 days saponin and salt it is mixed Close solution；Chemistry or fish medicine pollution are avoided by the above method or inhibits moss to sprout while murder by poisoning, and to blood red egg It is white to have very strong killing effect for the biology of O_2 carrier, and to using white azurin as the crab shrimp of O_2 carrier and biological feed There is no killing effect；
2）Water filling, and launch daily fermentation poultry dung and chlorella, it is continuous launch three days, 10 days after detect water transparence, If transparency is more than 45cm, continue to launch chlorella, until transparency is less than or equal to 45, launches 85kg/ mus of spiral shell；Pass through The step reduces water transparence, and carries out appropriate rich water；
3）It is sprinkled into bacillus licheniformis powder and yeast bacterium powder beside from aerator, and plants waterweed, Huang into culture pond Silk grass, hydrilla verticillata grass-seed, eel grass grass-seed, hornwort, water caltrop and water lily grass, make pool bottom water grass coverage rate reach 80%-85%；Heavy water Water plant, which carries out photosynthesis, can improve the dissolved oxygen amount in water body, moreover it is possible to decompose the poisonous and harmful substance in water；
4）85kg/ mu of spiral shell is launched, and inspects periodically pool bottom water grass coverage rate, when coverage rate is less than 80%, then fills into water chestnut Angle；
5）Intercropping freshwater shrimp while launching river crab, juvenile freshwater shrimp quantity are 6 kilograms per acre, and freshwater shrimp is food with organic debris Material supports freshwater shrimp Neng Minus and lacks residual bait clast to water pollution, while launching spiral shell again, and injected volume is 110kg/ mus.
Step 1）The aqueous solution mass concentration of the bur celery extract is 50%-60%, usage amount 900-1000L/ Mu.
Step 1）The preparation method of the bur celery extract：
A) bur celery crushed 70 mesh sieve, and the water that 10 times of medicinal material amounts are added impregnates 2 hours, then decocts 2 hours, filters To decocting liquid, the water that the dregs of a decoction add 8 times of medicinal material amounts decocts 1.5 hours, decocting liquid is obtained by filtration, the dregs of a decoction discard；
B) decocting liquid filtered twice is merged, is condensed into medicinal extract, vacuum drying obtains dry cream, crushes to get to bur Celery water extract.
Step 1）The mass concentration and application method of the mixed solution of the saponin and salt be：It is thrown in 1000kg water Enter the salt of the saponin and 5kg of 25 kg -37.5kg, splash after impregnating 10 hours, the amount of splashing is 100kg/ mus.
Step 2）The chicken manure injected volume is 45-50kg/ mus, a concentration of 1.2 ten thousand cell of chlorella/liter, injected volume is 1200-1500 liters/mu.
Step 3）The input amount of the bacillus licheniformis powder and yeast bacterium powder is 80g/ mus.
Method of the present invention can effectively prevent the generation of moss, and whole process is environmentally friendly and harmless, avoids poisoning Effect, and reduce hand labor intensity.
Specific implementation mode
The ecology prevention that pond carries out moss is supported in Changshu, Jiangsu Province river crab master within 2013, include the following steps：
