Abstract

The invention provides an organic selenium-rich fertilizer. The organic selenium-rich fertilizer is obtained by adding water to animal wastes, residual vegetables, food residues and other wastes as well as rape seed cakes; fermenting the mixture; filtering the mixture by 120-200 meshes; adding the sodium selenate to the filtered mixture; and dissolving the mixture, wherein the concentration calculated by selenium element is 25-35 g/L. During the stable period of the rice, 150 ml selenium-rich fertilizer diluted by 550-700 times of water is sprayed to each acre of land. The application effect is that the selenium content of the agricultural product can be obviously increased and the percentage of the organic selenium in the total selenium of the agricultural product is obviously increased; moreover, the organic selenium-rich fertilizer provided by the invention is suitable for being used in domestic selenium deficient or low-selenium regions and has positive significance on increasing the selenium level of the crowd.

Description

A kind of organic Se-rich fertilizer

Technical field:

The invention belongs to the fertilizer production technology field, relate to a kind of organic Se-rich fertilizer.

Background technology:

Selenium is one of essential trace element of humans and animals; In anti-cancer, anticancer; The vital role of aspects such as prevention and treatment cardiovascular disorder, Keshan disease and Kaschin-Beck disease has been generally acknowledged by common people; Selenium can significantly reduce the incidence of multiple cancers such as mammary cancer, skin carcinoma, colorectal carcinoma, liver cancer, has special physiological functions such as the heavy metal poisoning of releasing.U.S. scientist current research proves that also selenium deficiency is the universals of aids patient in the body." selenizing protection " become the focus of the many scientist's researchs in the world.

Strengthen rich selenium food exploitation, have important commercial and economic worth, build up people's health especially, at present, it is low that southern area rice contains selenium, and it is very serious to HUMAN HEALTH prestige association to lack selenium.Most of place, Jiangsu is to lack the selenium area, and Qidong liver cancer, Yancheng lung cancer, intestinal cancer and mammary cancer etc. are all relevant with the scarce selenium of local people's meals.So mending selenium is significant for improving the people ' s health level.

Animal is mended selenium and makes an addition to food with Sodium Selenite in the past, and its biological effectiveness is low, and absorption scope (50-400ug/ days) is narrow, the easy problem that produces excess intake and poison.Sodium Selenite soil application and foliage-spray, because of soil fixing and a large amount of drifts, not only selenium validity is low, and security and less economical, so can not become the benefit selenium measure that agricultural-food are produced.Selenium is generated interior absorption selenium-enriched fertilizer through biotechnical processes, can effectively be absorbed, thereby the security that realizes agricultural-food is efficiently produced by plant.

At present; People's life draws rubbish a lot, and letting as residual dish, surplus slag revulses draws rubbish to handle to let the people have a headache, and the present invention utilizes to draw rubbish to transform to have very much useful energy fertilizer in these daily lifes; Promptly protected ecotope, economic worth has been arranged again.

Summary of the invention:

The objective of the invention is to provide a kind of organic Se-rich fertilizer, is low to selenium validity in the prior art, and security and less economical; The defective that lacks the benefit selenium measure of agricultural-food production solves the not enough problem of selenium in farmers''s product, and simple to operate; Low production cost is preserved the ecological environment.

The present invention realizes through following technical scheme:

(1), with animal excrement, residual dish, surplus slag etc. and rapeseed cake drop into fermentation vat, add suitable water, add a cover fermentation 40-50 days, to stink a little.

(2), continue to add water, continuation fermentation 20-40 days, extremely the solid composition dissolving in the batching;

(3), get fermented liquid 120-200 order and filter, get organic Se-rich fertilizer mother liquor;

(4), add sodium selenate 3-5kg, dissolve and stir, do not have deposition, obtain organic Se-rich fertilizer after reacting completely and get final product can by every 100kg mother liquor.

The organic Se-rich fertilizer of above-mentioned acquisition is stored concentration and is counted 25-35g/L with the selenium element.

Organic Se-rich fertilizer provided by the present invention is used for the working method of selenium-enriched crop, and its advantage and positive effect are:

(1), selenium-enriched fertilizer can significantly improve the selenium content in the agricultural-food.Selenate, selenite combine with humic acid (HA), can prolong selenium also duration of contact on blade face, thereby help the absorption to selenium.

(2), the important factor that influences the validity of selenium in the food except selenium content, the chemical form of selenium also is an important factor, the biological activity of organoselenium component is higher than inorganic selenium form selenium

(3), be applicable to that China lacks selenium area or low selenium area, improve crowd's selenium level, it is significant to prevent and cure diseases.

(4), simple to operate, cost is low, the refuse of utilization, useless resource has the better protecting effect to ecotope.

Embodiment:

(1), with pig manure 50kg, rapeseed cake 200kg, residual dish, surplus slag 50kg drop into fermentation vat, add water 150kg and add a cover fermentation 45 days, to little stink occurring.

(2), add water 500kg, continuation fermentation 20 days, extremely the solid composition dissolving in the batching;

(3), get fermented liquid 200 orders and filter, obtain the selenium-enriched fertilizer mother liquor;

(4), add Sodium Selenite 4kg, dissolve and stir, do not have deposition by the 100kg mother liquor, after reacting completely selenium-enriched fertilizer get final product can.

The organic Se-rich fertilizer of being produced, safe, easy to use, easy to implement.

Claims

1. organic Se-rich fertilizer, it is characterized in that: this fertilizer is to produce through following method:
