Description
Technical field
The present invention relates to a kind of selenium-rich product, specifically a kind of Se-enriched bio fertilizer and its preparation and application,
Belong to selenium-rich product scope.
Background technology
Selenium is one of important trace element of needed by human body, and it has anti-oxidant and anti-aging ability, still, selenium member
The supplement of element, selenium element is not innately to be present in food, and current selenium-rich product is all that crop is in growth course by fertilising
Middle to absorb the fertile of selenium element and produce, the intake of selenium and the Se content relation of soil are more than the relation with diet style.
The soil of America ＆ Canada contains enough selenium, has selenium in the food that its many crop is made.It is well known that vegetalitas is eaten
The Se content of thing is decided by the Se content in local water and soil, such as, China produces in high selenium area the Se content of grain up to per public
Jin 4-8 milligrams, and the grain in low selenium area is 0.006 milligram of per kilogram, the two 1000 times of difference.Strengthen the selenium-rich in soil,
Selenium content in crops is improved, there is important business ＆ economy to be worth, even more build up people's health.At present, in soils in south china
Low containing selenium, selenium deficiency is assisted extremely serious to health prestige.So selenium-supply is significant for improving people's health level.
So in order that the food that plant absorbs enough selenium elements from soil and then makes to obtain turns into selenium-rich product, it is necessary to soil
Earth is improved, especially the improvement to poor selenium soil, is badly in need of selenium fertilizer.At present, the selenium fertilizer of agricultural is generally applied to selenite, selenium
Based on the inorganic selenium salts such as hydrochlorate, such selenium fertilizer is not only difficult to be absorbed by crops, and bioavailability is low, and the high bleed rate of toxicity
Secondary environment harm is also easy to produce soon.
The content of the invention
In order to solve the above problems, the present invention devises a kind of Se-enriched bio fertilizer and its preparation and application, uses
Toxicity is low, directly can efficiently be utilized and cheap DL- selenomethionine dusty yeasts are as selenium source by biological, and by it with moving
The appropriate times that ferment together such as thing excrement, plant ash, pine nut shell, vinasse, dregs of beans, pleurotus eryngii mushroom bran and tea seed cake, are converted
For the macromolecular substances in organic fungi-manure or its absorption is set to be scattered in the inside for having organic fertilizer, this can not only effectively reduce DL- selenium
For natural long-term effect and the slow release for being lost in, improving selenium source of methionine, moreover it is possible to strengthen the harmony that selenium fertilizer is applied.
The technical scheme is that：
A kind of Se-enriched bio fertilizer, is prepared by the raw material of following parts by weight：
Animal wastes 20-30 parts, plant ash 4-11 parts, pine nut shell 1-6 parts, vinasse 2-7 parts, sugarcane top 1-6 parts, dregs of beans 1-8 parts,
Pleurotus eryngii mushroom bran 1-6 parts, DL- selenomethionine 1-5 parts, mountain chrysanthemum stalk 1-5 parts, rapeseed meal 3-9 parts, tea seed cake 2-10 parts.
Preferably, the DL- selenomethionines are the DL- selenomethionine yeast that Se content is mass fraction >=0.15%
Powder；Humidity≤50% of the animal wastes, remaining dry material humidity≤30%.
The preparation method of above-mentioned Se-enriched bio fertilizer is：
（1）Stocked up according to above-mentioned weight proportion；
（2）Fermentation raw material is smashed to granularity≤3mm, and is sufficiently mixed；
（3）Fermentation, transfer the material into the installation for fermenting that part is stirred with machinery, carry out aerobic/anaerobic and alternately ferment；
Fermentation condition is：Raw meal particle size≤3mm, moisture content >=40%, 60 DEG C >=temperature >=35 DEG C, regular turnover ensure
Oxygen/anaerobism alternating, 9.0 >=pH >=6.5, fermentation time 3-7 weeks, you can obtain Se-enriched bio fertilizer of the present invention.
The application method of above-mentioned Se-enriched bio fertilizer is：Greengrocery crop, base manure >=3500kg/667m2, 1 top dressing >=
300kg/667m2；Fruit tree, base manure >=8kg/ strains, 3 top dressings >=1kg/ strains；Rice, base manure >=3000kg/667m2；Wheat drought
Cess food crop base manure >=2000kg/667m2；Other economy >=3000kg/667m such as Chinese yam, glutinous rehmannia2。
The advantage of the invention is that：Using toxicity it is low, directly can efficiently be utilized and cheap DL- seleno eggs by biological
Propylhomoserin dusty yeast is as selenium source, and by itself and animal wastes, plant ash, pine nut shell, vinasse, dregs of beans, pleurotus eryngii mushroom bran and tea seed cake
Deng the appropriate time that ferments together, with the macromolecular substances being translated into organic fungi-manure or it is scattered in its absorption to have organic fertilizer
Inside, this can not only effectively reduce the natural loss of DL- selenomethionines, improve long-term effect and the slow release of selenium source, moreover it is possible to
Strengthen the harmony that selenium fertilizer is applied；Crop absorption is fast, utilizing status is good, and comprehensive nutrient is balanced, and selenium source effective time is long and green
It is environment friendly and pollution-free.
With reference to specific embodiment, the invention will be further described.
Embodiment
