Abstract

The invention provides an aquaculture rapid water fertilization method with a biogas slurry dilution manner. A pond with water depth higher than 1m and with no impurities such as aquatic plant is adopted. The pond can be used for culturing approximately 30% of filter-feeding fish, 40-50% of omnivorous fish and 20-30% of herbivorous fish, specifically silver carp, bighead carp, carp, crucian carp, grass carp, bream and black carp. The application of biogas residue and biogas slurry should be determined according to specific conditions of the fish pond. The application amount of the biogas slurry per Mu of the water surface each time cannot exceed 300kg, and the application amount of the biogas residue per Mu of the water surface each time cannot exceed 150kg. The application times cannot exceed 3 times per week. Application should be carried out with a whole-pond spreading manner in sunny days, once every other day. The method has the following advantages: when biogas slurry is used for culturing fish, disease can be reduced; biogas slurry is processed through composting and anaerobic fermentation, such that eggs and germs inside are eliminated, and the occurrences of fish diseases can be effectively controlled and reduced.

Description

The quick rich water method of a kind of aquaculture utilizing biogas slurry to dilute

Technical field

The invention belongs to technical field of aquaculture, utilize biogas slurry to dilute the quick rich water method of aquaculture particularly to one.

Background technology

Biogas slurry is breeded fish, and has a lot of advantages, and biogas slurry, through becoming thoroughly decomposed and anaerobic fermentation, removes worm's ovum therein and pathogenic bacteria, therefore can effectively control and reduce the generation of fish diseases, can be effectively improved the nutritional condition in fish pond, promote planktonic breeding and growth, thus improving the yield of fish.

Summary of the invention

To be solved by this invention problematically, overcome the deficiencies in the prior art, it is provided that the quick rich water method of a kind of aquaculture utilizing biogas slurry to dilute.

This invention address that it technical problem is that takes techniques below scheme to realize:

The quick rich water method of a kind of aquaculture utilizing biogas slurry to dilute, the pond depth of water is more than 1 meter, without foreign material such as pasture and water in water；Can being used in cultivation filter-feeder fish about 30%, omnivorefish 40%～50%, the pond of phytophage fish 20% ~ 30%, concrete kind has Hypophthalmichthys molitrix, Aristichthys nobilis, Cyprinus carpio, Carassius auratus, Ctenopharyngodon idellus, bream, Mylopharyngodon piceus；Biogas residue, using of biogas slurry should be determined according to the concrete condition in fishpond, and each every mu of water surface biogas slurry consumption not can exceed that 300 kilograms, and biogas residue consumption is less than 150 kilograms, use weekly less than 3 times, use and should carry out at fine day, use 1 time every other day, adopt the mode of full pool spilling head.

Further, biogas residue also can branch be used, adhere to the principle of spot application, concrete control method can be determined according to the water quality in season and fishpond, be typically in for 4～May, 10～November controls water transparence and is not less than 25 centimetres, 6～JIUYUE controls water transparence and is not less than 15 centimetres, if the transparency of Chi Shui is lower than above-mentioned standard, then can not use biogas residue, biogas slurry；Torridity summer, should use with caution, it has been found that fish should stop to execute when raising the nose above water to breathe；Muggy weather and thundery sky adhere to the principle repeatedly used on a small quantity, as there are the anoxia phenomenons such as fish floating head, will take oxygen supplement measure in time, it is possible to hasten to add and renew water, it has been found that fish diseases, search the cause of disease in time, suit the remedy to the case.

Further, biogas residue can make the base manure in fishpond, it is possible to topdresses, biogas slurry then should be used as to topdress, biogas residue and biogas liquid can use in rotation, when biogas residue is used as base manure, after sterilize in fishpond, put fry before need to be modulated into by biogas slurry that the solution containing solids concentration 1% is bold and vigorous to be watered, the biogas slurry extracted out from methane-generating pit can directly use, but placing 3h effect used above can be better, when the biogas slurry concentration containing solids is about 1% time, can directly pour in fishpond, weekly, each consumption is less than 500g/m2.

Further, specifically using, time of topdressing, consumption, will according to season, climate change and fishpond water quality flexible arrangement, its leading indicator is water colour transparency, if water colour transparency just to impose more than 30cm, then should not impose less than 20cm, impose every time and should select to carry out the morning at fine day；Topdressing, the 4-6 month executes weekly biogas slurry 3000kg/hm2；The 7-8 month executes weekly biogas slurry 2250/hm2；The 9-10 month executes weekly biogas slurry 2250/hm2.It is best that fertilization time fine day 8:00-10:00 executes biogas slurry；Cloudy day can not execute；There is wind weather, splash with the wind；Muggy weather, thunderstorm is not executed before arriving.Within when water transparency is more than 30cm every 2 days, execute a biogas slurry, execute biogas slurry 1500 ~ 2500kg/hm2 every time, after becoming 25 ~ 30cm until transparency, proceed to normal fertilising.

The present invention compared with prior art has significant advantage and beneficial effect: biogas slurry is breeded fish and can be alleviated disease, and biogas slurry, through becoming thoroughly decomposed and anaerobic fermentation, removes worm's ovum therein and pathogenic bacteria, therefore can effectively control and reduce the generation of fish diseases；Secondly can improve yield, after biogas slurry is used in fish pond, the nutritional condition in fish pond can be effectively improved, promote planktonic breeding and growth, thus improving the yield of fish；Additionally biogas slurry carries out aquaculture, aquaculture cost can be saved, improving the production performance of Aquatic product and nutritional labeling, biogas residue and biogas liquid can direct plunge into feeds fish in pond, also can admix and feedstuff is fed fish, biogas slurry need not carry out solid-liquid separation, biogas slurry and biogas residue and can rotation use when using, it is possible to use simultaneously, biogas slurry has certain reproducibility, takes out from methane-generating pit and places 3 hours better effects if used above.
