Description
技术领域technical field
本发明涉及养殖池塘清淤领域,具体涉及一种养殖池塘生物清淤的方法。The invention relates to the field of dredging ponds, in particular to a biological dredging method for ponds.
背景技术Background technique
目前,我国池塘养殖水体富营养化现象普遍发生,淤泥过厚、水味腥臭、有害藻类过度繁殖、生物多样性下降,严重威胁鱼类健康,影响鱼的产量与品质。近年来,虽然在养殖水体中使用各种微生物以及底排污等措施来改善水质,但是从富营养化程度来看,水体各营养状态指数比其以前并未下降。可见养殖水体一旦形成富营养化就很难彻底恢复。At present, the phenomenon of eutrophication in pond aquaculture water is common in our country. Excessive silt, foul smell, excessive reproduction of harmful algae, and decline in biodiversity seriously threaten the health of fish and affect the yield and quality of fish. In recent years, although measures such as various microorganisms and bottom sewage have been used in aquaculture water bodies to improve water quality, from the perspective of eutrophication, the nutrient status index of water bodies has not declined compared to before. It can be seen that once the aquaculture water body becomes eutrophic, it is difficult to completely recover.
消除养殖池塘水体中的氮、磷以及有机负荷才能从根本上解决水体富营养化。目前,国内外常用物理、化学、生物方法或这几种方法相结合来处理内源性污染。底排污的方法需要大量的水资源补充,在我国西部地区,水资源严重缺乏;机械清淤的方法成本过高,且对防止水体富营养化只能起到延缓作用,从根本上解决不了养殖池塘水质逐渐恶化的问题。微生物处理的方法由于成本低、无二次污染等特点,是养殖池塘常用的方法,但是养殖池塘每天投饵量大,鱼类排泄的废物多,还有众多其它影响因素,其治理方法并不能在人为控制条件下进行。Elimination of nitrogen, phosphorus and organic loads in the water body of aquaculture ponds can fundamentally solve the eutrophication of the water body. At present, physical, chemical, biological methods or a combination of these methods are commonly used at home and abroad to deal with endogenous pollution. The method of bottom sewage discharge requires a large amount of water resources to be replenished. In the west of China, water resources are seriously lacking; the cost of mechanical dredging is too high, and it can only delay the prevention of eutrophication in water bodies, and cannot fundamentally solve the problem of aquaculture. Pond water quality is gradually deteriorating. Due to the low cost and no secondary pollution, the method of microbial treatment is a commonly used method in aquaculture ponds. However, the daily feeding amount of aquaculture ponds is large, the waste excreted by fish is large, and there are many other influencing factors. The treatment method cannot carried out under human control.
目前有人利用常用的几种微生物净化养殖水体,通过微生物对造成富营养化的某种或几种有机物污染物的吸收利用,控制藻类过度繁殖,消除底泥,但微生物对内源性有机污染物的降解速度远远小于养殖生物每天排放的粪便。在中国专利公报上曾公开了一种“一种利用微生物有效控制藻类水华的方法”的发明创造,其申请号201110021920.8,该方法利用芽孢杆菌、不动杆菌、反硝化细菌、光合细菌菌液按比例混合投放到养殖池塘,对养殖池塘水体各污染物的去除率分别是:TN为83.1%,TP为92.1%,COD为79.1%,Chla为90.1%,但在集约化养殖池塘的清淤速度还是显慢了些。。At present, some people use several commonly used microorganisms to purify aquaculture water, and control the overgrowth of algae and eliminate sediment through the absorption and utilization of certain or several organic pollutants that cause eutrophication. The degradation rate is far less than the feces discharged by farmed organisms every day. In the Chinese Patent Bulletin, an invention of "a method for effectively controlling algae blooms by using microorganisms" was disclosed. Its application number is 201110021920.8. Mixed in proportion and put into the culture pond, the removal rate of each pollutant in the culture pond water body is respectively: TN is 83.1%, TP is 92.1%, COD is 79.1%, Chla is 90.1%, but in the dredging of intensive culture pond The speed is still slow. .
发明内容Contents of the invention
为解决上述问题,本发明提供了一种养殖池塘生物清淤的方法,利用由四川华腾水产生化科技开发有限公司提供的的微生物和底栖鱼类用来养殖池塘的清淤,可以克服上述缺点,更适用于精养殖池塘的清淤。In order to solve the above problems, the invention provides a method for biological dredging of aquaculture ponds, utilizing microorganisms and benthic fish provided by Sichuan Huateng Water Production Technology Development Co., Ltd. for dredging ponds, which can overcome the above-mentioned problems. Disadvantages, it is more suitable for dredging ponds.
为实现上述目的,本发明采取的技术方案为:In order to achieve the above object, the technical scheme that the present invention takes is:
一种养殖池塘生物清淤的方法,包括如下步骤:A method for biological dredging of breeding ponds, comprising the steps of:
S1、当养殖池塘的水位达到100cm后,每亩投放规格为500克的鲢鱼和鳙鱼各为100尾,规格为30克的鲤鱼200尾,规格为30克的鲫鱼800尾;S1, when the water level of the breeding pond reaches 100cm, put in 100 tails of silver carp and bighead carp with a specification of 500 grams per mu, 200 tails of carp with a specification of 30 grams, and 800 tails of crucian carp with a specification of 30 grams;
S2、将枯草芽孢杆菌、酵母菌、光合细菌液体菌液按体积比例为1-3∶1-2∶1-3的比例混合成混合菌液,投放到养殖水体,投放量为养殖水体体积的0.1‰-0.2‰,其中,水温20℃-25℃,每隔15天投放混合菌液1次,投放量为养殖水体体积的0.2‰,水温25℃以上每隔7天投放混合菌液1次,投放量为养殖水体体积的0.1‰,以后每次投放菌液处理水质前,测定水质TN、TP及COD指标,根据监测结果确定连续投放混合菌液处理养殖水体时间。S2. Mix Bacillus subtilis, saccharomyces, and photosynthetic bacteria liquid bacteria liquid in a volume ratio of 1-3:1-2:1-3 to form a mixed bacterial liquid, and put it into the aquaculture water body, and the amount of input is 1/2 of the volume of the aquaculture water body 0.1‰-0.2‰, among them, when the water temperature is 20°C-25°C, the mixed bacterial solution is added once every 15 days, and the dosage is 0.2‰ of the volume of the aquaculture water body, and the mixed bacterial solution is added once every 7 days when the water temperature is above 25°C , the dosage is 0.1‰ of the volume of the aquaculture water body. Before each time the bacterial solution is used to treat the water quality, the water quality TN, TP and COD indicators are measured. According to the monitoring results, the time for continuous injection of the mixed bacterial solution to treat the aquaculture water body is determined.
本发明具有以下有益效果:The present invention has the following beneficial effects:
1.清淤彻底。利用几种菌混合液、滤食性鱼类及底栖鱼类,经过10-12个月,池塘淤泥由50-110cm降低到20cm以下,甚至无淤泥,节约了机械清淤的成本。1. Thorough dredging. Using several kinds of bacterial mixture, filter-feeding fish and benthic fish, after 10-12 months, the pond silt is reduced from 50-110cm to below 20cm, or even no silt, which saves the cost of mechanical dredging.
实现了节水养殖。1个养殖周期内,在水温不超过25℃的情况下,实现了只进水、不排水的养殖模式,在高温季节,20天换一次水,换水量只为10%。即使在我国西部水源紧缺地区,也可以实现高产。Water-saving farming has been realized. In one breeding cycle, when the water temperature does not exceed 25°C, the breeding mode of only water intake and no drainage is realized. In the high temperature season, the water is changed every 20 days, and the water change volume is only 10%. Even in water-scarce areas in western my country, high yields can be achieved.
增加了养殖水域的有效生物量,提高了经济效益。淤泥过厚,池塘老化,养殖水位下降,鱼的单位产量降低,通过生物清淤,产量可提升50%。The effective biomass of the breeding water area is increased, and the economic benefit is improved. The silt is too thick, the pond is aging, the water level of the culture drops, and the unit output of fish decreases. Through biological dredging, the output can be increased by 50%.
降低了饵料系数。普通的养殖模式,3+草鱼的饵料系数通常为2.3-2.5,采用这种养殖模式,饵料系数可达2.0,节约养殖成本,提高鱼产量。Reduced bait coefficient. In the common breeding mode, the bait coefficient of 3 + grass carp is usually 2.3-2.5. With this breeding mode, the bait coefficient can reach 2.0, which saves the cost of breeding and increases the fish output.
减少了疾病发生。普通养殖模式中,鱼类的肝胆综合症很常见,每年因肝胆综合症和水质恶化引起翻塘的事件很常见。利用微生物、滤食性鱼类和底栖鱼类进行清淤后,即使鱼类出现严重浮头,鱼类死亡数也不会超过1‰。Reduced disease occurrence. In the common farming mode, hepatobiliary syndrome of fish is very common, and it is very common to overturn ponds every year due to hepatobiliary syndrome and water quality deterioration. After dredging with microorganisms, filter-feeding fish and benthic fish, the number of fish deaths will not exceed 1‰ even if the fish suffers from severe head floating.
水质改善,降低了养殖水域调水药的用量。池塘淤泥厚,池塘氨氮、硫化氢含量超标,常用化学药品,造成水质二次污染。The water quality has been improved, reducing the amount of water transfer medicine used in aquaculture waters. The pond silt is thick, the content of ammonia nitrogen and hydrogen sulfide in the pond exceeds the standard, and chemicals are commonly used, causing secondary pollution of water quality.
