CN103524183A - Fertilizer for enhancing selenium absorptivity of crops - Google Patents

Abstract

The invention discloses a fertilizer for enhancing selenium absorptivity of crops. The fertilize comprises the following components in parts by weight: 400-500 parts of pig manure and duck manure mixture, 30-50 parts of alfalfa, 80-120 parts of tobacco stem and tobacco leaf fertilizer, 50-80 parts of corncobs with corn kernels, 40-60 parts of sludge, 10-30 parts of golden cypress powder and 80-120 parts of shell powder. The fertilizer is simple in proportioning, has high selenium content and can obviously increase the selenium content of soil and further obviously increase the crop absorptivity. In the used raw materials, spinach, tobacco stem and tobacco leaf fertilizer, golden cypress powder and shell powder are the crops with high selenium ingredient and the fertilizer for enhancing selenium absorptivity of crops is obtained by steps of grinding these crops and then stirring the powder, fermenting the powder with a ferment, adjusting the water content through turning and throwing after the powder becomes thoroughly decomposed, and finally granulating the powder. After application of the organic fertilizer, the selenium content of the crops planted in the land short of selenium is increased by 35% compared with the selenium contents of the traditional crops, and the selenium content of the food prepared from the crops is improved by 18-22%.

Description

A kind of fertilizer that strengthens crop selenium element absorption rate

 

Technical field:

The present invention relates to technical field of fertilizers, relate in particular to a kind of fertilizer that strengthens crop selenium element absorption rate.

 

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, urgent need strengthens the fertilizer of crop selenium element absorption rate.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 a kind of fertilizer that strengthens crop selenium element absorption rate 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 a kind of fertilizer that strengthens crop selenium element absorption rate of crop absorption ratio.

To achieve these goals, the invention provides a kind of fertilizer that strengthens crop selenium element absorption rate, wherein, comprise the following component of parts by weight:

Pig manure and duck excrement mixture 400-500 part, Alfalfa 30-50 part, tobacco rod and tobacco leaf fertilizer 80-120 part, with corn ear 50-80 part of corn grain, mud 40-60 part, golden cypress powder 10-30 part, oyster shell whiting 80-120 part.The weight ratio of pig manure and duck excrement mixture is, pig manure: duck excrement is 4:1.

Or, comprise the following component of parts by weight:

Pig manure and duck excrement mixture 400-450 part, Alfalfa 30-40 part, tobacco rod and tobacco leaf fertilizer 80-100 part, with corn ear 50-70 part of corn grain, mud 40-50 part, golden cypress powder 10-20 part, oyster shell whiting 80-100 part.

Or, comprise the following component of parts by weight:

Pig manure and duck excrement mixture 450-500 part, Alfalfa 40-50 part, tobacco rod and tobacco leaf fertilizer 100-120 part, with corn ear 60-80 part of corn grain, mud 50-60 part, golden cypress powder 20-30 part, oyster shell whiting 100-120 part.

Or, comprise the following component of parts by weight:

Pig manure and duck excrement mixture 420-480 part, Alfalfa 35-45 part, tobacco rod and tobacco leaf fertilizer 90-110 part, with corn ear 55-65 part of corn grain, mud 45-55 part, golden cypress powder 15-25 part, oyster shell whiting 90-11 part.

 

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, tobacco rod and tobacco leaf fertilizer, golden cypress powder, oyster shell whiting 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 at the be enhanced fertilizer of crop selenium element absorption rate of granulation, 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%.
