Abstract
The invention provides an organic selenium-enriched foliar fertilizer special for leaf vegetables, and relates to the technical field of selenium-enriched foliar fertilizers. The organic selenium-enriched foliar fertilizer comprises the following components in percentage by weight: 0.01-5.0% of 2-phenylureido-3-selenium methyl propionate, 0.01-2.0% of selenomethionine, 0.01-1.0% of an organic silicon dispersing agent, 5.0-20.0% of organic base and the balance of water. The organic selenium-enriched foliar fertilizer provided by the invention has the advantages of small dosage and wide working concentration range, can be used for significantly improving the selenium content of the leaf vegetables, and also has significant effects of improving the quality of vegetable leaves, promoting the growth and development of the vegetables and increasing the yield; and compared with an inorganic selenium-enriched foliar fertilizer, the organic selenium-enriched foliar fertilizer has the advantages of low toxicity, small environmental pollution and high bioavailability.
Description
Technical field
The present invention relates to foliage fertilizer technical field, particularly selenium-enriched foliage fertilizer, specifically belong to special organic Se-rich foliage fertilizer of a kind of leaf vegetables and preparation method thereof.
Background technology
One of 14 kinds of trace elements that the humans and animals that the Xi Shi World Health Organization generally acknowledges is necessary, achievement in research shows, 40 various diseases are all relevant with scarce selenium in the world, selenium is bad to cancer, diabetes, asthma, hyperlipidemia disease, arteriosclerosis, skin, cataract, nephropathy, heart trouble, hepatopathy, rheumatosis, and allergic constitution, sacroiliitis, stomach ulcer, obesity, hypertension etc. all have very high prevention effect.But it is but extremely unbalanced that selenium distributes at the earth's surface, the whole world has multiple countries and regions to lack selenium in various degree, and China about has 72% area to lack selenium, and some areas of 15 provinces, cities and autonomous regions particularly from northeast to southwest constitute in " poor selenium area ".
Selenium element in humans and animals body is mainly derived from food, the selenium content insufficiency of intake of food source, will have influence on the healthy growth of man and animal.Therefore by high-quality and efficient Se-rich farm products key technology research and integration and demonstration, to the rich selenium of the farm crop such as veterinary antibiotics, grain, develop rich selenium food, supplement human body necessary selenium element by food chain approach healthy significant to the various diseases such as preventing cancer, guarantee people.
But, no matter domestic or external, except only a few research institution uses organoselenium (selenomethionine, seleno-protein) to carry out except small-scale research as the interpolation fertilizer of Se-rich farm products, nearly all Se-rich farm products all comes from district rich in selenium (selenium-rich soil) or uses inorganic selenium (tin anhydride, Sodium Selenite or sodium selenate) as vegetable fertilizer, and its use operation comprises seed dressing, root is executed, water or the various ways such as foliage-spray.In addition, compared with inorganic selenium, organoselenium has that toxicity is little, environmental pollution is little, bioavailability advantages of higher.And be used alone Sodium Selenite and carry out soil application and foliage-spray, because of soil fixing and a large amount of loss, not only selenium validity is low, and security and less economical, therefore can not become the benefit selenium measure that agricultural-food produce.Therefore, exploitation is used for the inexorable trend that the organic selenium compounds of high-quality and efficient Se-rich farm products is rich selenium industry development.
Summary of the invention
The object of the invention is for existing selenium-enriched fertilizer Problems existing in actual applications, as lower in plant utilization rate, working concentration is higher, thus there is the phenomenon of hindering leaf wound fruit, then easily there is the situations such as contaminated soil as base manure, special organic Se-rich foliage fertilizer of a kind of leaf vegetables and preparation method thereof is provided.This selenium-enriched foliage fertilizer can improve the selenium content in leaf vegetables, simultaneously to improving vegetable leaf quality, promoting vegetable growth, obvious effect of increasing production.The rich selenium that this selenium-enriched foliage fertilizer is also applicable to the vegetables such as other stem dish classes sprays.
The special organic Se-rich foliage fertilizer of leaf vegetables of the present invention, components based on weight percentage: 2-phenylureido-3-selenium methylpropanoic acid 0.01-5.0%, selenomethionine 0.01-2.0%, organosilicone spreading agent 0.01%-1.0%, organic bases 5.0-20.0%, water surplus.Described organosilicone spreading agent can as well wet, foretell interior top grade commercially available prod; Described organic bases can be the compounds such as ammoniacal liquor, dimethylamine, triethylamine.
Organic Se-rich foliage fertilizer preparation manipulation method is: step is:
A, by component proportion according to claim 1,2-phenylureido-3-selenium methylpropanoic acid, selenomethionine are dissolved in distilled water successively, and constantly stir, obtains lysate, for subsequent use;
B, again by after organosilicone spreading agent water dissolution, add above-mentioned lysate, abundant stirring and evenly mixing;
C, add organic bases regulate pH to 6.8-7.0, supply moisture, namely obtain product.
The application process of organic Se-rich foliage fertilizer, is characterized in that by selenium-enriched foliage fertilizer thin up 20-1000 doubly directly carry out foliage-spray, January sprays once before leaf vegetables is gathered, and gathers and sprays once in first 15 days, spray twice altogether.
Organic Se-rich foliage fertilizer of the present invention also can be used for other stem vegetableses.
Compared with prior art advantage of the present invention and effect: the present invention adopts 2-phenylureido-3-selenium methylpropanoic acid as the selenium element donor of leaf vegetables and growth regulator, selenomethionine is auxiliary selenium donor, be aided with organosilicone spreading agent and increase solution divergence and sticking power, then add that organic bases regulator solution potential of hydrogen is composite to be formed.It is little that this organic Se-rich foliage fertilizer has consumption, working concentration wide ranges, while significantly improving leaf vegetables selenium content, to improving leaf vegetables leaf quality, promoting that leaf vegetables grows, obvious effect of increasing production.Compared with inorganic selenium-enriched foliage fertilizer, have that toxicity is little, environmental pollution is little, bioavailability advantages of higher.
