Abstract

The invention discloses a preparation method of selenium supplying fertilizer. The method includes the following steps of firstly, smashing fermented wood bits, smashing lophatherum gracile, smashing bean straw, and evenly mixing the powder for standby application; secondly, putting a mixture of sweet potato leaves and waste whey with the mass ratio of 20 to 1, a mixture of spinach and selenium-rich soil with the mass ratio of 1 to 3, floating aquatic plant dry powder, fermented wood bits, a mixture of clay and medical stone powder with the mass ratio of 10 to 1, sophora flavescens powder and lophatherum gracile into a fermenting pool, adding water till the materials are submerged in water, covering the pool with a plastic film, and fermenting the materials for 25 to 30 days; thirdly, making 1-3 parts of enzymes have the 500-fold volume concentration, pouring the enzyme into the fermenting pool, and continuing to conduct cover-sealed fermenting for 10 to 12 days till solid components in the material are dissolved; fourthly, adding 3-5 parts of selenium additives to the material in the second step, wherein the selenium additives are sodium selenite. The preparation method is simple, the prepared product is simple in ratio, the organic fertilizer is high in selenium content, the soil selenium content can be remarkably increased, and the crop absorption rate is remarkably increased.

Description

A kind of selenium element supplements fertile manufacture method

Technical field:

The present invention relates to technical field of fertilizers, particularly relate to a kind of selenium element and supplement fertile manufacture method.

Background technology:

Selenium is one of trace element of needed by human, it has anti-oxidant and ability that is that delay senility, but, supplementing of selenium element, selenium element is not innately be present in food, current rich selenium product is all that the fertilizer that crop absorbs selenium element in process of growth is produced, and the picked-up of selenium and the selenium content relation of soil exceed the relation with diet style by fertilising.The soil of America & Canada contains enough selenium.So have selenium in the food that a lot of crop is made, the selenium content of plant food is decided by the selenium content in local water and soil, such as, China height selenium area institute produces the selenium content of grain up to per kilogram 4 ~ 8 milligrams, and the grain in low selenium area is per kilogram 0.006 milligram, and the two differs 1000 times.Strengthen the exploitation of rich selenium food, have important business & economy and be worth, build up people's health especially, at present, southern area rice is low containing selenium, lacks selenium very serious to HUMAN HEALTH prestige association.Major part place, Jiangsu is scarce selenium area, and it is relevant that Qidong liver cancer, Yancheng lung cancer, intestinal cancer and mammary cancer etc. all lack selenium with local people's meals.So mend selenium, raising people ' s health level is significant.So, from soil, absorb enough selenium elements to make plant and then make the food obtained become rich selenium product, must improve soil, especially to the improvement in poor selenium soil, being badly in need of selenium element and supplementing fertile.In view of this technical problem, need to occur that a kind of manufacture method is simple, obtained product proportioning is simple, and in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then a kind of selenium element significantly improving crop absorption ratio supplements fertile manufacture method.

Summary of the invention:

The object of the invention is to overcome the shortcoming existed in prior art, there is provided a kind of manufacture method simple, obtained product proportioning is simple, and in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then a kind of selenium element significantly improving crop absorption ratio supplements fertile manufacture method.

To achieve these goals, the invention provides a kind of selenium element and supplement fertile manufacture method, it is characterized in that, comprise the steps:

A, by fermentation after wood chip pulverize, Herba Lophatheri pulverize, pulse family class crushed stalk, is all crushed to size 100-120 order, for subsequent use;

B, be 20:1 mixture by pachyrhizus leaf and discarded whey mass ratio, spinach and rich selenium soil mass ratio are 1:3 mixture, hydrophyta natantia dry powder, wood chip after fermentation, clay and medical stone powder according to the mixture of massfraction than 10:1 proportioning, Lightyellow Sophora Root, Herba Lophatheri is put in fermentation vat, add water to and do not have material, above capping plastic film, fermentation 25-30 days;

C, go 1-3 part ferment proportioning to 500 times of volumetric concentrations, be poured in fermentation vat, continue capping fermentation 10-12 days, dissolve to the solid content in batching;

D, material in step B is added 3-5 part selenium additive, selenium additive is Sodium Selenite, material is derived after stirring, repeatedly throwing is turned over anti-throwing machine, every airing turns over throwing once in 3 days, when being 45-55% to water content, adding trace element and stirs, send into forcing machine and carry out extruding pelletization, namely the particle obtained obtains selenium element and supplements the supplementary fertilizer of fertile selenium element after drying.

It is 10-20g/ kilogram that step D gained selenium element supplements fertile selenium constituent content.

Supplement fertile through the selenium element that manufacture method of the present invention is obtained, wherein, comprise the following component of parts by weight:

Pachyrhizus leaf and discarded whey mass ratio are 20:1 mixture 400-500 part, spinach and rich selenium soil mass ratio are 1:3 mixture 30-50 part, hydrophyta natantia dry powder 80-120 part, wood chip 50-80 part after fermentation, clay and medical stone powder are according to massfraction mixture 40-60 part than 10:1 proportioning, Lightyellow Sophora Root 10-30 part, Herba Lophatheri 80-120 part.

Or, comprise the following component of parts by weight:

Pachyrhizus leaf and discarded whey mass ratio are 20:1 mixture 400-450 part, spinach and rich selenium soil mass ratio are 1:3 mixture 30-40 part, hydrophyta natantia dry powder 80-100 part, wood chip 50-70 part after fermentation, clay and medical stone powder are according to massfraction mixture 40-50 part than 10:1 proportioning, Lightyellow Sophora Root 10-20 part, Herba Lophatheri 80-100 part.

Or, comprise the following component of parts by weight:

Pachyrhizus leaf and discarded whey mass ratio are 20:1 mixture 450-500 part, spinach and rich selenium soil mass ratio are 1:3 mixture 40-50 part, hydrophyta natantia dry powder 100-120 part, wood chip 60-80 part after fermentation, clay and medical stone powder are according to massfraction mixture 50-60 part than 10:1 proportioning, Lightyellow Sophora Root 20-30 part, Herba Lophatheri 100-120 part.
