Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of selenium-rich type microbial-bacterial fertilizer and preparation method thereof.
Background technique
Selenium is the essential trace elements of the human body, is the important component of part antioxidase and selenoprotein in human body.It grinds
Study carefully and shows that selenium has a variety of important physiological functions, such as healthy, the anti-oxidant, cancer-resisting that protection is cardiovascular and myocardium.People
Body selenium deficiency will lead to such as a variety of diseases of Keshan disease, cardiovascular and cerebrovascular diseases, cancer, hypertension.Selenium can not generate in vivo, human body institute
The selenium needed can only be absorbed from food.The area of China 72% belongs to selenium deficiency or low selenium area, and national about 2/3rds populations are deposited
It is insufficient in different degrees of selenium intake.Although selenium is not nutrient necessary to plant, plant is that nature selenium ecology is followed
The direct sources of key link and human body selenium in ring.Se content is generally relatively low in natural food, is given birth to by technique of enriched selenium
It is selenium-supply mode common at present that object, which is strengthened,.Currently, selenium-rich meat products, microorganism is that the functional food of carrier has all obtained accordingly
Research and development, and the most commonly used carrier of selenium-enriched food is mostly plant food.Plant has to be absorbed by root and blade
The characteristics of microelement can absorb using plant and be enriched with inorganic states selenium, and be translated into easy for plant to absorpt utilize
The characteristic of form selenium carries out research and the corresponding product of research and development of external source selenium-rich.Strengthen selenium to plant using selenium-rich fertilizer to have been demonstrated
It is a kind of safe, low cost, efficient and convenient selenium-rich means.In low selenium area, the adjusting of plant Se content can take root application, leaf
Face the methods of sprays, soaks seed or dress seed, and the Se content at the positions such as root, stem, leaf, the fruit of plant is improved, to meet humans and animals
Psychological need.
Although selenium is not nutrient necessary to plant, with to selenium in further investigation agriculturally, the kind of selenium-rich fertilizer
Class is also varied.Blade face selenium-rich fertilizer can be divided by the difference of fertilization mode and base applies selenium-rich fertilizer；It can be divided by material situation solid
Body selenium-rich fertilizer, liquid selenium-rich fertilizer；According to the chemical component of fertilizer, inorganic selenium-rich fertilizer, organic selenium-rich fertilizer can be divided into.In recent years,
Occurs the novel selenium-enriched fertilizer of a batch again.
Biological selenium-rich fertilizer refers to biological agent using biotechnology manufacture, having specific fertilizer efficiency to crop, effectively
Ingredient can be specific living organism, the metabolin of organism or conversion product of matrix etc., and this organism is either micro-
Biology is also possible to animal and plant tissue and cell.However, Biological Selenium fertilizer bioavailability is not high at present, fertilizer efficiency is not significant enough,
Higher cost, market application is insufficient, it is still desirable to further to improve.
Summary of the invention
To solve problems of the prior art, a kind of selenium-rich type microbial-bacterial fertilizer is provided, the fertilizer efficiency is significant, at
This is cheap, is suitble to all kinds of crops to use, and can promote crop quality and yield, improves soil environment, has wide city
Field application value.The present invention also provides the preparation methods of the microbial-bacterial fertilizer.
