Description
Technical field
The present invention relates to fertilizer and preparation method thereof, particularly relate to a kind of selenium-enriched organic fertilizer and preparation method thereof.
Background technology
Selenium is a kind of multi-functional life nutritional element; energy scavenging free radicals, anti-oxidant, the powerful generation suppressing peroxidation character; strengthen immunologic function (20-30 doubly), protection biological cell membrane, strengthen prostate gland regulatory function, prevent blood clot, remove cholesterol; there is the effect identical with Regular Insulin; obviously can promote ability and the blood circulation of cellular uptake sugar; prevent skin aging; reduce luring of carcinogenic substance carcinous, remove the cancer cells of vivo mutations, the division stoping cancer cells and growth etc.
China's famous nutritionist Yu Ruo wood is pointed out: will mend selenium as enriching the iodine, and writes inscription " selenium-enriched food, healthy food, desirable food ".Along with the development of science and technology, selenium is more and more familiar with by people, is called as " the special effect element of life ", " kindling material of life ", " life five elements ", " sight protectio god ", " anticancer king ", titles such as " the 21st seed amino acids ".
There are 22 provinces, municipalities and autonomous regions in China, and the territory of 72% is in serious scarce selenium area, comprises the ground such as northeast, North China, the southeast.Modern medicine proves, selenium is one of bioelement of needed by human, not only there is the value of disease therapy, also have effect of anti-treating diseases and making health-care, the total content in human body is 1420 milligrams, to be distributed widely in body in all histoorgans, concentration height person has liver, pancreas, the heart, spleen, tooth and nail, in fat, concentration is minimum, plays important regulating effect to human homergy, in October, 1988 Chinese Soclety of Nutrition by selenium one of 15 kinds of nutritive elements being classified as needed by human.
China is in the selenium research leading level in the world, the international analysis on trace blue ribbon prize of physician Zeng Huo " Schwarz " Grand Prix of China.Biological half-life due to selenium is about two weeks, and metabolism is fast in vivo, must constantly supplement, so supply Se scientific is global problem, mends inorganic selenium and is not easily absorbed by the body, and easily poisoning, and it is high that selenium price mended by medicine, and population can not consumed.Therefore, by using selenium-enriched organic fertilizer to farm crop, fruit tree, vegetables etc., people are rich in organoselenium agricultural-food to reach by edible grain and gourd, fruit and vegetable etc. and are carried out regular benefit selenium to human body, are economical and practical approach.
Use selenium-enriched organic fertilizer, can impel plant disease-resistant insect pest, robust plant, each agricultural products is bright in colour, completely filled fruit, and taste is aromatic thick, and mouthfeel is improved, and reaches the object of supplementary organoselenium, to improve the health level of people after edible.Facts have proved, the agricultural-food using selenium-enriched organic fertilizer output are high, the quality better of output not only, and organic selenium content exceeds tens times than common agricultural.So by using selenium-enriched organic fertilizer to all kinds of plant, people often eat containing organoselenium agricultural-food, are of great significance for the health level tool improving constantly people.
Therefore, there is a kind of selenium-enriched fertilizer of requirement developing this area, improves the organic selenium content of agricultural-food, reaches artificial object of supplementing organoselenium.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of selenium-enriched fertilizer and preparation method thereof.In described selenium-enriched fertilizer, selenium exists with the form of organoselenium, by plant absorption such as farm crop, fruit tree, vegetables, is rapidly absorbed by a human afterwards, efficiently solves the demand of people to selenium.
