Abstract

The invention discloses a selenium fertilizer for improving selenium-poor soil. The selenium fertilizer comprises the following components in parts by weight: 400 to 500 parts of chicken and duck manure mixture, 30 to 50 parts of food residue, 80 to 120 parts of gramineous straw, 50 to 80 parts of corncob with corn kernels, 40 to 60 parts of bentonite, 10 to 30 parts of radix scutellariae powder and 80 to 120 parts of purple sweet potato. The selenium fertilizer is easy to proportion and high in selenium content, so that the selenium content of the soil can be remarkably improved, and the crop absorption rate can further be remarkably increased; spinaches, the gramineous straws, the radix scutellariae powder and the purple sweet potatoes in the raw materials are crops with higher selenium content, and the selenium fertilizer for improving the selenium-poor soil is obtained by crushing and stirring the raw materials, fermenting a mixture by using enzymes, decomposing the mixture, overturning the mixture to adjust the water content, and performing granulation; the selenium content of crops planted on a selenium-poor land to which the selenium fertilizer is applied is 35 percent higher than that of crops planted on a selenium-poor land to which a conventional fertilizer is applied, and the selenium content of food obtained by the crops is improved by 18 to 22 percent.

Description

The poor selenium soil of a kind of improvement is fertile with selenium

 

Technical field:

The present invention relates to technical field of fertilizers, relate in particular to the poor selenium soil of a kind of improvement fertile with selenium.

 

Background technology:

Selenium is one of trace element of needed by human, it has anti-oxidant and ability that delay senility, but, supplementing of selenium element, selenium element is not to be innately present in food, current rich selenium product is all that crop absorbs the fertilizer of selenium element in process of growth produces by fertilising, and the selenium content relation of the picked-up of selenium and soil surpasses the relation with diet style.The soil of America & Canada contains enough selenium.So, in the food that a lot of crops are made, there is selenium, the selenium content of plant food is decided by the selenium content in local water and soil, for example, the selenium content of the high selenium of China area grain that produces is up to 4 ~ 8 milligrams of per kilograms, and the grain in low selenium area is 0.006 milligram of per kilogram, and the two differs 1000 times.Strengthen rich selenium food exploitation, 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.Most of place, Jiangsu is to lack 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 people ' s health level.So, for the food that makes plant absorb enough selenium elements from soil and then to make to obtain becomes rich selenium product, must improve soil, the especially improvement to poor selenium soil, is badly in need of improving poor selenium soil fertile with selenium.In view of this technical problem, need to occur that a kind of proportioning is simple, in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then obviously improves the selenium fertilizer for the poor selenium soil of a kind of improvement of crop absorption ratio.

 

Summary of the invention:

The object of the invention is to overcome the shortcoming existing in prior art, provide a kind of proportioning simple, in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then obviously improves the selenium fertilizer for the poor selenium soil of a kind of improvement of crop absorption ratio.

To achieve these goals, the invention provides the poor selenium soil of a kind of improvement fertile with selenium, wherein, comprise the following component of parts by weight:

Chicken manure and duck excrement mixture 400-500 part, swill 30-50 part, gramineous straw 80-120 part, with corn ear 50-80 part of corn grain, wilkinite 40-60 part, Baical Skullcap Root 10-30 part, purple potato pachyrhizus 80-120 part.

Or, comprise the following component of parts by weight:

Chicken manure and duck excrement mixture 400-450 part, swill 30-40 part, gramineous straw 80-100 part, with corn ear 50-70 part of corn grain, wilkinite 40-50 part, Baical Skullcap Root 10-20 part, purple potato pachyrhizus 80-100 part.

Or, comprise the following component of parts by weight:

Chicken manure and duck excrement mixture 450-500 part, swill 40-50 part, gramineous straw 100-120 part, with corn ear 60-80 part of corn grain, wilkinite 50-60 part, Baical Skullcap Root 20-30 part, purple potato pachyrhizus 100-120 part.

Or, comprise the following component of parts by weight:

Chicken manure and duck excrement mixture 420-480 part, swill 35-45 part, gramineous straw 90-110 part, with corn ear 55-65 part of corn grain, wilkinite 45-55 part, Baical Skullcap Root 15-25 part, purple potato pachyrhizus 90-11 part.

The part by weight of chicken manure and duck excrement mixture is, chicken manure: duck excrement is 3:1

Proportioning of the present invention is simple, and in fertilizer, selenium content is high, can significantly improve soil selenium-containing amount, and then obviously improves crop absorption ratio.In the starting material that the present invention uses, spinach, gramineous straw, Baical Skullcap Root, purple potato pachyrhizus is all containing the higher crop of selenium composition, after being pulverized, also stirs, by ferment, ferment, after becoming thoroughly decomposed, by turning over, throw to regulate water content fertile with selenium at the granulation poor selenium soil that improves, use the poor selenium soil of this fertilizer, the more traditional raising 35% of selenium content of the crop of plantation, the selenium content of the food of this crop gained improves 18-22%.
