Abstract
The invention relates to a preparation method and an application of a selenium-enriched foliar fertilizer. The preparation method comprises the steps as follows: the selenium-enriched foliar fertilizer is prepared by sodium selenate, sodium selenite, fulvic acid, urea, compound sodium nitrophenolate, SDS (sodium dodecyl sulfate) and the balance water; and the sodium selenate and the sodium selenite are taken as donors of selenium, the fulvic acid is taken as a chelating agent, the compound sodium nitrophenolate is taken as a plant growth regulator, and the fertilizer is compounded by adding the plant growth regulator compound sodium nitrophenolate and the urea and the SDS. The selenium-enriched foliar fertilizer is mainly used for crops such as wheat, corn, tomatoes, muskmelons, sugar beet, red dates, walnuts, apples, bergamot pears and the like, and can provide the selenium element for the crops and improve the selenium contents in the crops. The selenium contents of the crops are improved by 128.6-275.0% while compared with those of crops without using the selenium-enriched foliar fertilizer.
Description
Technical field
The present invention relates to a kind of preparation method and application of selenium-enriched foliage fertilizer.
Background technology
Selenium is one of essential trace element of humans and animals, and in China, the low selenium of environment is to cause that multiple prevailing disease is as one of factor of Kaschin-Beck disease, Keshan disease, animal white myopathy.Facts have proved, scarce selenium area crowd suitably mends selenium and can obtain good medical effect.The picked-up of selenium in human body, the selenium that mainly relies on food to contain.The height of Selenium In Foods content is directly connected to the mankind's health, and normal contents should be between 0.1ppm-1.0ppm, is less than 0.1ppm selenium deficiency, and being greater than 3-5ppm is toxic dose.Mended selenium Sodium Selenite in the past and make an addition to food, its biological effectiveness is low, and absorption scope (50-400ug/ days) is narrow, easily produces excess intake and poisoning problem.With Sodium Selenite 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 are produced separately.Selenium compound is generated to foliage fertilizer after by chelating, can effectively be absorbed by plant, improve Selenium in Plants content, reach the object of mankind's supplement selenium.
The fertilizing method that fertilizer after dilution is dissolved is sprayed directly on crop blade face is referred to as leaf dressing.Leaf dressing is one of conventional fertilizing method of peasant.Foliage fertilizer has the features such as nutrition absorption is fast, utilization rate of fertilizer is high, easy to operate, and along with the development of agriculture production, leaf dressing has become an important measures of fertilizer.
Can solve the selenium compound problem that the selenium that occurs fixes and run off that is manured into soil by leaf dressing, plant can effectively absorb selenium element.
Summary of the invention
The object of the invention is to, a kind of preparation method of selenium-enriched foliage fertilizer is provided, in the method, selenium-enriched foliage fertilizer is to be made up of sodium selenate, Sodium Selenite, yellow humic acid, urea, sodium nitrophenolate, sodium laurylsulfonate and water surplus, adopt sodium selenate, the Sodium Selenite donor as selenium, yellow humic acid is as sequestrant, and plant-growth regulator sodium nitrophenolate, then add urea and sodium laurylsulfonate is composite forms.This selenium-enriched foliage fertilizer is mainly used in the crops such as wheat, corn, tomato, muskmelon, beet, red date, walnut, apple, bergamot pear, can effectively provide selenium element to crop, improves the content of selenium in crop.Improve 128.6-275.0% with respect to the contrast selenium content that does not use selenium-enriched foliage fertilizer.
The preparation method of a kind of selenium-enriched foliage fertilizer of the present invention, this foliage fertilizer is to be that sodium selenate 0.01-5.0%, Sodium Selenite 0.01-2.0%, yellow humic acid 0.5%-10.0%, urea 5.0-20.0%, sodium nitrophenolate 0.1-1.0%, sodium laurylsulfonate 0.5-1.5% and water surplus are made by weight ratio, and concrete operations follow these steps to carry out:
A, respectively sodium selenate, Sodium Selenite are dissolved in distilled water, slowly add yellow humic acid, and constantly stir, obtain lysate, for subsequent use;
B, water dissolves sodium nitrophenolate again, adds urea and sodium laurylsulfonate, stirs to dissolve to mix, and obtains lysate;
C, again step a and step b two portions lysate are mixed after, add ammoniacal liquor to regulate pH to 6.5-6.8, supply moisture, obtain product.
The purposes of the selenium-enriched foliage fertilizer that described method obtains, adds dilution 100-2000 doubly by the selenium-enriched foliage fertilizer obtaining, foliage-spray, and every mu of 100ml, converts clear water 10-200kg, starts to spray mid-May, sprays once every 20 days, sprays altogether 4 times to mid-July.
The purposes of the selenium-enriched foliage fertilizer that described method obtains, this selenium-enriched foliage fertilizer is wheat, corn, tomato, muskmelon, beet, red date, walnut, apple or bergamot pear for farm crop.
The preparation method of a kind of selenium-enriched foliage fertilizer of the present invention and application are compared with traditional foliage fertilizer, and its advantage is: this selenium-enriched foliage fertilizer is easy to use, cost is low, instant effect; Can effectively improve crop selenium content.Improve 128.6-275.0% with respect to the contrast selenium content that does not use selenium-enriched foliage fertilizer.
