Description

A kind of method of utilizing weter hyacinth to breed vermiculture soft-shelled turtle in mulberry ground
Technical field
The present invention relates to a kind of ecological cultivation method, relate in particular to a kind of method of utilizing weter hyacinth to breed vermiculture soft-shelled turtle in mulberry ground.
Background technology
At present, fishery system in the whole nation is harnessing the river as the breach that advances culture fishery upgrading transition, " making the transition, short harnessing the river---modern ecological fishery construction is taken action " formulated in Zhejiang Province's plan, reduce the negative effect of the traditional fishery mode of production to environment, performance aquatile disappear " positive energy " of dirty water purification, promote the minimizing of the widespread pollution from the overuse of fertilizers and pesticides in rural area such as feed, agricultural chemicals, chemical fertilizer, reduce aquaculture total nitrogen and total phosphorus.
A large province of silkworm and mulberry is originally in Zhejiang Province, since the mid-90 in 20th century, because the fluctuation of the silk market price strengthens, the competitive pressure aggravation of agricultural industry internal market, unit are output benefit is not high, silkworm raiser's enthusiasm for production baffles, and obviously, the mulberry field area of the whole province constantly dwindles at present on sericulture there landslide.For extricating oneself from a predicament, put forth effort to strengthen silkworm and mulberry comprehensive utilization of resources research, extend industrial chain, improves added value, just seems and is even more important.
" mulberry fish pond " is actually a kind of composite artificial ecological structure, i.e. mulberry-silkworm-fish and water land ecosystem refers to the ecological recycle system pattern of " base kind mulberry, breed fish in the pool, mulberry leaf are raised silkworm, silkworm excrement is fed fish, pond sludge training mulberry "." mulberry fish pond " complex ecosystem is taking Sang Ji as basis, and fish pond is crucial.Fish pond itself is the basis that is input as with feed, fertilizer.Feed, fertilizer abundance, foster fish is also many, and shoal of fish excretion is larger, and pond bottom sediment is corresponding increase also, and this has formed richer material base concerning " supporting " base.From ecologic structure global analysis, obviously, the basic guarantee that " supporting " good base is " mulberry fish pond " Conversion of Energy and storage.This collection kind mulberry, the ecospecies cultivation pattern of breeding silkworms, breeding fish are the comprehensive circulation patterns of one that makes full use of land resources, performance biological production potentiality.
Breeding soft-shell turtle is mainly divided into three kinds of patterns at present, and one is greenhouse cultivation, and the advantage of greenhouse cultivation is soft-shelled turtle all Fast Growths whole year, and under nature soft-shelled turtle almost only at just Fast Growth in summer, its advantage relatively, shortcoming also clearly, maintain high temperature, thereby to consume a lot of fuel, because soft-shelled turtle is always in the Fast Growth stage, also to consume a large amount of feeds, therefore, greenhouse cultivation cost is very high, and in addition, greenhouse cultivation is serious environment pollution also; The second is that put in a suitable place to breed in fish pond, the soft-shelled turtle seedling general individual that put in a suitable place to breed in fish pond is larger, can first in greenhouse, cultivate a period of time, after more strong Deng the health of soft-shelled turtle seedling, transferring to fish pond puts in a suitable place to breed again, it is low that relative cost is put in fish pond in a suitable place to breed, but the soft-shelled turtle that put in a suitable place to breed in fish pond is not liked food very much, grows slow yet, generally needs within 3 years, just can grow up to above; The third is high ecologic breeding, high ecologic breeding is all generally directly the little soft-shelled turtle seedling of buying to be raised scattered in being mainly used in supporting the fish pond of four large Chinese carps, and cultivation density is very low, the pond of general 20 mu, only put hundreds of tail in a suitable place to breed, and in this hundreds of tail, most of meeting is by natural selection, on raiser's energy is placed on and breeds fish, the food of soft-shelled turtle is looked in pond by soft-shelled turtle oneself, soft-shelled turtle after growing up to is generally below hundred tails, sometimes surplus tail more than 10 even only, but this class soft-shelled turtle is popular on market, price is also very high.
Also do not have at present a kind of cultural method can accomplish that cost is low, growth is fast, high ecology.
Summary of the invention
The present invention will solve the problems of the technologies described above, thereby provide, a kind of production cost is relatively low, the method for growth phase to the relatively high cultivation soft-shelled turtle of very fast, ecological degree.Be to provide or rather a kind of method of utilizing weter hyacinth to breed vermiculture soft-shelled turtle in mulberry ground.

As technique scheme preferably, step 3. in, while watering, water noon in winter, water evening in summer, spring and autumn, season, watered daytime.
Ecologic breeding, ecological two words are mainly reflected on the food of soft-shelled turtle, if soft-shelled turtle eats is living food, so just can be referred to as ecology.If soft-shelled turtle not only eats living food, and before need to look for food on the feed, what need to waste time and energy to food arrests, and can be referred to as highly ecological.Can eat if soft-shelled turtle also will be stood for a long time without food, even, also finding after food life-and-death struggle with it, can be referred to as wild.According to above-mentioned definition, cultural method of the present invention is between ecological and highly between ecology, because before earthworm is formed, the food of soft-shelled turtle is taking feed as main, and after earthworm is formed, the food of soft-shelled turtle is mainly earthworm, if not enough, then spreads small part feed; During this, it is not artificial feeding that soft-shelled turtle eats earthworm, and this needs soft-shelled turtle oneself from fish pond, to climb up pool base, and then oneself finds earthworm.
The feeding effect of earthworm feedstuff is more much better than commercial feed, almost can meet all nutritional needs of all famous and precious aquatic livestocks.In Zhejiang Province, soft-shelled turtle has become special aquaculture key industry, and the East Sea also will promote the larger effect of earthworm performance without fish.The soft-shelled turtle survival rate that puts in a suitable place to breed in fish pond is low, feed coefficient is low, if select earthworm meat mincing or earthworm powder to feed soft-shelled turtle, the survival rate of soft-shelled turtle can promote greatly, and formation speed is relatively very fast, and individual healthy and strong well-balanced, quality might as well.The present invention is by extracting pond eutrophy and transfer techniques assembling mode; pond eutrophy is passed through to weter hyacinth; transfer the organic substrate that Sang Jizhong cultivates earthworm to; utilize Sang Ji vacant lot to breed earthworm; earthworm grows up to the interior environmental conditions of rear control medium; allow earthworm oneself climb out of, thereby set up artificially a kind of food chain, cultivate soft-shelled turtle by food chain technology.The present invention, by setting up the reasonable food chain of " mulberry fish pond ", couples together the material recycle of several parts and energy flow, finally improves mulberry fish pond system synthesis benefit.
The present invention has following beneficial effect:
1, the present invention is by extracting pond eutrophy and transfer techniques assembling mode, pond eutrophy is passed through to weter hyacinth, transfer the organic substrate that Sang Jizhong cultivates earthworm to, utilize Sang Ji vacant lot to breed earthworm, earthworm grows up to the interior environmental conditions of rear control medium, allow earthworm oneself climb out of, thereby set up artificially a kind of food chain, cultivate soft-shelled turtle by food chain technology;
2, the present invention, by setting up the reasonable food chain of " mulberry fish pond ", couples together the material recycle of several parts and energy flow, finally improves mulberry fish pond system synthesis benefit;
3, in the present invention, after earthworm grows up to, can own from earthworm medium, climb out of, just in time ingested by soft-shelled turtle, as earthworm climbs out of less, can on earthworm medium, water, water and can force earthworm automatically to climb out of.
