Description
Technical field
The present invention relates to technical field of fertilizers, be specifically related to a kind of selenium-rich controlled release fertilizer and preparation method thereof.
Background technology
Selenium is by one of World Health Organization's 15 kinds of elements being published as needed by human.Selenium has directly pass with the health of human body
System, the eighties, China scientist studies discovery, and including cancer, hepatitis, diabetes, cardiovascular and cerebrovascular vessel, arthritis etc., kind more than 40 is direct
Causing disease, kind more than 400 causes disease all to lack selenium with human body indirectly direct relation.
Selenium is a kind of multi-functional life nutritional element, has antioxidation, enhancing immunity, and protection, repair cell, before enhancing
Row gland regulatory function, prevents blood clot, removes cholesterol, can be obviously promoted cellular blood circulation, defying age, prevent skin old
Change, prevent the biological function such as canceration, suppression tumor.It is referred to as " the special effect element of life ", " atom in body trace element
Bullet ", " kindling material of life ", " life five elements ", " sight protectio god ", " anticancer king ", the title of " the 21st kind of aminoacid ".
But, selenium element is not innately to be present in food, and current selenium-rich product is all to produce by executing fertilizer rich in selenium
Come.The Se content of plant food is decided by the Se content in local water and soil.The food in China's Se content low selenium area is with high
The Se content of the produced food in selenium area differs 1000 times, and there are county (city) the low selenium of 72% or scarce selenium in China, and some seriously lack selenium ground
The Keshan disease in district, Kashin Beck disease pathogenesis rate are significantly higher than other areas.Strengthen the exploitation of selenium-rich food, there is important business and warp
Ji is worth, and lacks selenium and threatens extremely serious to health.Major part place, Jiangsu is to lack selenium area.So selenium supplement is for improving people
People's health level is significant.
The application of existing selenium-enriched organic fertilizer is limited, poor effect, and production cost is higher, causes its actually used impact very
Greatly.Current slow-release or control-release fertilizer also still suffers from many problems: production cost is the highest, complex process, slow controlled release properties are unstable or slow
Release material difficult degradation, thus limit the popularization and application of sustained-controll-release fertiliser.Therefore the control rich in organic selenium of a kind of Cheap highly effective is developed
Release fertilizer and become the emphasis of research.
Summary of the invention
It is an object of the invention to, it is provided that in a kind of low cost, fertilizer, organic selenium content is high, and controlled release properties is stable, easy
Degraded, will not contaminated soil and water source, significantly improve soil selenium-containing amount, hence it is evident that improve utilization rate of fertilizer, it is achieved stable high yield
A kind of controlled release fertilizer rich in organic selenium.
For solving above-mentioned technical problem, it is achieved above-mentioned purpose, technical scheme is as follows: one of the present invention
