Description

Based on rice, fish, the production method of duck selenium-rich circular agriculture
Technical field
The present invention relates to circular agriculture, specifically selenium-rich circular agriculture, more specifically based on rice, fish, the circulation agriculture of duck selenium-rich The production method of industry.
Background technology
It has been at present the circular agriculture mode of production of a kind of comparative maturity that duck rice mixes up, and cultivates Hehua fish also in rice field It it is the characteristic circular agriculture mode of production of Guilin and Chenzhou, Hunan Province.
But prior art there are no rice, fish, the document of duck selenium-rich circular agriculture.
Summary of the invention
In order to make up the deficiencies in the prior art, it is achieved rice, fish, the production of duck selenium-rich circular agriculture, it is achieved rice, fish, duck richness Selenium agricultural product industry promotes mutually, and the present invention provides a kind of based on rice, fish, the production method of duck selenium-rich circular agriculture.
The technical scheme that the present invention realizes above-mentioned purpose is as follows.
Based on rice, fish, the production method of duck selenium-rich circular agriculture, rice cultivation in selenium-rich soil, and raise together with fish, duck, Use selenium-enriched organic fertilizer;
Tend ducks: after rice transplanting 10 ~ 20 days after rice shoot is upright every mu put 15 ~ 25 ducklings in a suitable place to breed, by the end of April to planthopper mid-May Outburst peak period, every mu of increasing puts 5 ~ 10 second batch ducklings, regains duck at Rice Heading blooming stage, in drainage ditch of rice field The pool stable breeding communicated;
Breed fish: putting fish after regaining duck, the fingerling every mu of 8-15 centimetre puts 300 ~ 500 tails in a suitable place to breed;
During extremely regaining duck after tending ducks, use selenium-enriched organic fertilizer 1 ~ 3 time, every mu of each 10 ~ 50kg;
At Rice Heading to the pustulation period, use selenium-enriched organic fertilizer 3 ~ 5 times, every mu of each 50 ~ 100kg;
Described selenium-enriched organic fertilizer is prepared from plant rich in selenium for raw material is fermented;
Plant rich in selenium is garbage and/or the crucifer grown in selenium-rich soil district, the Herba Medicaginis of selenium-enriched crop;
Fermentation is carried out in the presence of microbe mixt, uses heap fermentation or hermetic container fermentation, and the water content of fermentation material is 50~70wt%, fermentation material and microbe mixt mass ratio are 30~50:1, fermentation 5 ~ 15 in the range of temperature is 45 ~ 65 DEG C My god;
Wherein: described microbe mixt is at least one in bacillus subtilis, yeast, lactobacillus and cellulase Mixture.
Owing to selenium mainly exists with organic selenium form in plant tissue, the selenium contained in plant rich in selenium belongs to biological state, What what the present invention used made with plant rich in selenium for raw material is exactly all wool and a yard wide selenium-enriched organic fertilizer, and selenium therein not only can be complete Entirely absorbed by agricultural product, and need not move through bioconversion, can directly be stored in agricultural product body.Additionally by sending out Ferment, plant rich in selenium, under microbe mixt effect, becomes the selenium-enriched organic fertilizer containing probiotics of slant acidity, after using, no But discharge ecological selenium directly to absorb for agricultural product, and soil can be improved, increase oxidability, make Se in soil4+Convert For Se6+, so that Se6+Content is greatly increased.And plant is to Se6+Absorb far above Se4+
Additionally, the selenium-enriched organic fertilizer raw material sources of the present invention are extensive, accomplish that twice laid and ecological circulation utilize, permissible Realize the transferring other spots application of native Se.
Before regaining duck, Oryza sativa L. is not required to too many organic selenium, now uses the selenium in selenium-enriched organic fertilizer the biggest Part is eaten into by duck.And the selenium-enriched organic fertilizer containing probiotics of slant acidity, after using, soil can be improved, increase Oxidability, makes Se in soil4+It is converted into Se6+, so that Se6+Content is greatly increased.So Se of output4+Mainly by duck Son absorbs.The probiotics lived also can enter in duck body, forms the circulation of optimum bacterium, beneficially duck health invigorating, health Grow up.Therefore the selenium-rich duck that yield height meat is good can be obtained.
The probiotics lived can continue to cause fermentation in rice field, and duck feces is smoothed out biological decomposition, it is provided that more Biological selenium, and other nutrient.
Weeds in field is trampled and is gnawed by duck and predation to insect (particularly planthopper) can substitute for weeding Agent, the use of insecticide.
In order to avoid duck running in rice field causes rice to use up, so needing to regain duck at Rice Heading blooming stage Son.Owing to the pool of stable breeding communicates with drainage ditch of rice field, so the paddy field water containing organic selenium and probiotic bacteria also can enter pond, Duck remains able to continue long-pending selenium, and the breeding process of selenium-rich duck proceeds.
Regaining after duck breeds fish, similar with the situation of duck, fish carries out selenium circulation too, and fish nature of also eating food falls The rice fallen, and atom in water, output manure fermentation decomposes, it is provided that more biological selenium, and other nutrient. The probiotics lived also can enter in fish body, forms the circulation of optimum bacterium, and beneficially fish health invigorating, grows up healthy and sound.The most also obtain The selenium-rich fish that yield height meat is good.
Owing to carrying out rice, fish, duck interplanting, the selenium-enriched organic fertilizer not fully absorbed by Oryza sativa L. just as fish, the nutrition of duck, Thus breeding selenium rich fish, duck rich in selenium, and the feces of selenium-rich fish, duck rich in selenium output as circulation output biological selenium-rich fertilizer, for Selenium rich rice provides the selenium-rich nutritive composition directly absorbed.The feces of fish and duck, at probiotic action bottom fermentation, also becomes meta-acid Property selenium-enriched organic fertilizer, improve soil further, increase oxidability, promote Se in soil4+It is converted into Se6+, so that Se6+ Content increases further, absorbs for Oryza sativa L..
In technical scheme, Oryza sativa L. is constantly in the growth course constantly absorbing organic selenium, particularly After Rice Heading to maturation be Rice Growing final period (the most solid period of maturation, it include heading, insemination of blooming, fill In the periods such as slurry and maturation, be to determine grain number and the critical period of grain weight), owing to increasing selenium-enriched organic fertilizer amount of application, more make Absorption that selenium is carried out by Oryza sativa L., convert, store and reach a climax.Therefore the organic selenium content in rice significantly improves.
Generally speaking, the present invention based on rice, fish, the production method of duck selenium-rich circular agriculture, it is achieved that rice, fish, duck are rich The production of selenium circular agriculture, it is achieved that rice, fish, duck Se-rich farm products industry promote mutually, significantly carries obtaining organic selenium content While high Semen oryzae sativae rich in selenium, the good selenium-rich fish of yield height meat and duck rich in selenium are also gathered in the crops.
