Abstract

The invention relates to a selenium-rich special biological organic compound fertilizer for producing functional farm products. The compound fertilizer is prepared by the following steps of: stirring and mixing a mycelium-amino acid mother solution, humic acid, animal manure, probiotics and compounds containing selenium and zinc serving as major raw materials, matching raw materials such as nitrogen, phosphorus and potassium, a high-strength water absorber, crop straw, stevia residues and the like in a bioreactor; fully fermenting and dehydrating till the water content is controlled at about 14 percent; and smashing to 50-75 meshes, and pelletizing. A formula can be used for producing a culturing base fertilizer for functional farm products containing beneficial trace elements such as selenium-rich paddy rice, selenium-rich wheat and selenium-rich tea; and by applying the fertilizer reasonably, the crop yield can be increased by 10-50 percent, the selenium content of a product can be up to 100-500 mcg/kg, and the requirements of national selenium-rich farm products are met.

Description

A kind of rich selenium special bio compoiste fertilizer of producing the functional type agricultural-food

Technical field

The present invention relates to a kind of is main organic base-material with farmers''s manure of livestock and poultry, stalk, soil ulmin; Add probiotic bacterium, selenium, zinc mineral compound and inorganic selenium, zinc are converted into the organic selenium zinc that is prone to the crop absorption through fermentation; Dehydrate again and add nitrogen, phosphorus, potassium fertilizer and stir to pulverize and be processed into that to contain organic granules of selenium multiple fertile, can be used for the base manure that farm crop such as paddy rice, wheat, tealeaves produce rich selenium product.

Background technology

Selenium is one of 15 kinds of trace elements of needed by human, is the most important anti-oxidant element of human body, and very strong detoxifcation, functions of expelling toxin are arranged.Cancer, hepatopathy, cardiovascular and cerebrovascular diseases etc. are relevant with scarce selenium, and selenium can be anti-ageing, promote human immunity.There is 72% the scarce selenium in territory in China, has and takes in minimum standard 50 micrograms (being merely about 38 micrograms) that selenium does not reach the WHO recommendation 2/3 crowd's day, and it is very urgent that the expert call whole people mend selenium.Through selenium content in the reinforcement cultivation conversion technology raising agricultural-food of crop is the road of the benefit selenium of a safety economy.The whole world is because a large amount of chemical fertilizer and little fertilizer of using has made soil compaction, and active the reduction not only can not be increased production, and the mouthfeel of crop also greatly descends.And selenium belongs to ultramicro-element, is at present most biological nutritive elements that all be short ofs, and research both at home and abroad shows that executing selenium fertilizer not only increases crop selemium nutrition value, and thing has resistance, can significantly increase production.At present domestic at the early-stage on special-purpose fertile application that the functional type agricultural-food are produced; Lack the compoiste fertilizer kind that contains organoselenium; The present invention is through organic materials and the mixed fermentation in bio-reactor of basic chemical fertilizer, and the conversion inorganic selenium is an organoselenium, through super-dry, pulverizing, granulation; The fertilizer of producing rich selenium is used for producing Se-rich farm products as base manure; Adapted to the demand of market, can make the total selenium of farm crop increase more than 50% raising the output 10%～50% functional type agricultural-food (particularly Se-rich farm products).

Summary of the invention

Technical problem to be solved by this invention provides a kind of new bio compoiste fertilizer that contains organoselenium, zinc, probiotic bacterium, nitrogen, phosphorus, potassium, organic matter, amino acid etc.; The ability activating soil; Increase the soil organism and improve output; Optimizing crops quality, is to produce the best base manure that contains the selenium functional food.

Principal feature of the present invention is: get animal dung 65～70%, humic acid 10～15%, mycelium amino acid mother liquor 5～10%, probiotic bacterium (potassium decomposing, phosphorus decomposing, methanobacteria, actinomyces, nitrifier etc.) trace element-selenium and zn cpds 2～5%; Total amount 95%; Moisture controlled about 60%, add an amount of superphosphate of lime with pH regulator 7.5～8.Adding multi-functional Inoculant mixes in organic materials; Adding cooperation raw material nitrogen, phosphorus, potassium fertilizer, high-strength absorbing agent and pulverizing such as stalk, stevioside ground-slag are mixed in and stir leavening temperature in the bio-reactor at 25～60 ℃ again; Whole fermentation time is 35 days; Moisture is reduced to below 40%; PH drops to 7, and wherein inorganic selenium and zinc are converted into organoselenium and the zinc (amino acid selenium and zinc) that is prone to the crop absorption through fermentation, for making the nutrition board equilibrium state of functional microorganism; Make the mixed C/N ratio of organic materials be controlled at 30～40 through stalk or the urea nitrogenous source that adds proper amount of carbon source, pulverizing during the organic materials mixed stack, dry back (moisture is less than 17%) is broken to 50～75 order granulations with urea, superphosphate of lime, Repone K powder mix.

Beneficial effect of the present invention is: biological fermentation is more conducive to the growth of plant, environmental protection, health.

Embodiment:

A kind of biological organic complex fertilizer that contains organoselenium; It is characterized in that: get (proportionings: animal dung 70% such as basic raw material mycelium amino acid mother liquor, stevia rebaudiana dregs (tealeaves is special-purpose), stalk, humic acid, chicken manure; Mycelium amino acid mother liquor 20%; Stalk and stevia rebaudianum slag etc. 10%) through (rice wheat coarse cereals: urea 6.25kg, superphosphate of lime 85.7%, Repone K 25kg, the liquid 300～500ml of selenium and zinc nutrition such as probiotic bacterium inoculation (total count＞500,000,000/gram), cooperation raw material nitrogen, phosphorus, potash fertilizer; Tealeaves: ammonium sulfate 95kg, superphosphate of lime 87.5kg, vitriolate of tartar 39kg; Selenium, zinc are the same), high-intensity water absorbent agent 10～20kg is mixed in biological respinse in device (25～60 ℃; 35 days) fully fermentation dehydration back powder mix be broken to 50～75 order granulations, measure nitrogenous 2.5%, P ₂O ₅0.8%, K ₂O0.7%, organic matter 30%, PH7, moisture about 14%.C/N is than 30～40.

Multifunctional microbial Inoculant → organic materials mixed preparing → add cooperate chemical fertilizer, high-strength absorbing agent → place bio-reactor → mechanical stirring ferment → become thoroughly decomposed → middle temperature is dried → magnet de-iron considers → is crushed to 50～75 order granulations to be worth doing.

The finished product available nutrient index:

These article are to contain selenium compoiste fertilizer particularly suitable production green organic function farm crop a kind of the 4th generation can increase the crop trace element nutritive ingredient, improve mouthfeel, are the inventions that does not appear in the newspapers as yet both at home and abroad at present.
