Description
Technical field
The present invention relates to agricultural technology field, specially a kind of selenium-rich synchronous slow paddy rice-dedicated 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.Chinese many areas belong to selenium deficiency or low selenium area, and national about 2/3rds populations exist
Different degrees of selenium intake is insufficient.Although selenium is not nutrient necessary to plant, plant is nature selenium ecological circulation
In key link and human body selenium direct sources.Using selenium-rich fertilizer to plant strengthen selenium have proved to be it is a kind of safety, it is low at
Originally, efficient and convenient selenium-rich means.
Selenium-rich rice also has anticancer, anti-cancer, cardioprotection and prolongs except the whole nutritional ingredients for having retained common rice
Slow aging, it is anti-oxidant with a variety of special healthcare functions such as eliminate free radical, improve the immunity of the human body.Meanwhile selenium is to plant growth
There is facilitation, mainly enhances the ability of plant adverse circumstance defence by selenium to realize.And during paddy growth often
By stressful environmentals such as high temperature, arids, therefore, the ability that selenium resists adverse circumstance to enhancing rice more has the meaning of reality.
The cultivated area of current selenium-rich rice is very wide, but there is a problem that various.For example, much planting family is made
Selenium fertilizer, it is fertile for commercially available universality selenium, and selenium-supply is carried out by the way of disposably applying, such mode, which lacks, to be directed to
Property, meanwhile, selenium element utilization rate is not high, and excessive selenium causes serious selenium contamination, not only pollution is generated to environment, to human body
Certain injury can be generated.
