CN103497041A - Selenium rich fertilizer and its preparation method - Google Patents

Abstract

The invention discloses a selenium rich fertilizer and its preparation method, and the selenium rich fertilizer is prepared from the following raw materials: by weight, 4-5 parts of sodium selenite, 24-28 parts of diatomite, 10-12 parts of a soil conditioner, 1-2 parts of chlorinated paraffin, 9-12 parts of urea, 20-24 parts of weathering coal, 9-11 parts of humic acid and 3-4 parts of propylene glycol; according to the selenium rich fertilizer, the sodium selenite is taken as a main body and cooperated with the urea, the absorption of crops on the sodium selenite is increased, at the same time, the chlorinated paraffin and the propylene glycol play slow release effects to promote the absorption and transformation of the crops on element selenium, the contents of organic-selenium beneficial ingredients in the crops can be increased, and the nutrition and health care values are increased.

Description

Selenium-enriched fertilizer and preparation method thereof

Technical field

The invention belongs to the compound manure technical field, biological organic and inorganic fertilizer material of especially being produced by Chinese medicine slag and preparation method thereof.

Background technology

Fertilizer, be to provide the essential nutritive element of one or more plants, improves soil property, a class material of the level of increasing soil fertility.One of basic substance of agriculture production.Fertilizer type is a lot, nitrogen is arranged, phosphorus, the chemical fertilizer such as potassium, dregs of beans is arranged, animal excrement, the organic fertilizer such as agricultural wastes, also have the bio-feritlizers such as biological bacteria, also has silicon, magnesium, iron, boron, the secondary and micro-element fertilizers such as selenium, numerous, Different Crop is due to different habits, different growth phases, demand to fertilizer is all not identical, therefore, need to be in conjunction with different crop varieties, study different fertilizer, be starved of, to improve quality and the speed of growth of crop, increasing corps nutrient is worth with health care, promote human health, to promote the well-being of mankind.

Summary of the invention

The purpose of this invention is to provide a kind of selenium-enriched fertilizer and preparation method thereof.

Technical scheme of the present invention is as follows:

A kind of selenium-enriched fertilizer is characterized in that being made by the raw material of following weight part: Sodium Selenite 4-5, diatomite 24-28, soil conditioner 10-12, clorafin 1-2, urea 9-12, weathered coal 20-24, humic acids 9-11, propylene glycol 3-4; Described soil conditioner is made by the raw material of following weight part:

Vermiculite power 12-15, attapulgite 20-25, zinc sulfate 1-3, Sodium Selenite 1-2, manganous sulfate 2-3, sal epsom 4-5, nano-sized carbon 0.4-0.5, clay 10-12, white lime 2-3, wintergreen oil 3-4, boric acid 2-3, tripoly phosphate sodium STPP 4-5, Silane coupling agent KH550 1-2, lapis amiridis 1-2, Paris white 4-5, water are appropriate;

Preparation method: after zinc sulfate, Sodium Selenite, manganous sulfate, sal epsom, nano-sized carbon mix, add wintergreen oil to stir, then, add again other remaining component except Silane coupling agent KH550, Paris white, be mixed into the mud shape, finally, add Silane coupling agent KH550, Paris white stirring-granulating, dry and obtain the preparation method of described selenium-enriched fertilizer, it is characterized in that urea is melted, add Sodium Selenite, clorafin to stir, then, then add other remaining component, mix, granulation, obtain

The present invention be take Sodium Selenite as main body, coordinates urea, increases the absorption of crop to Sodium Selenite, simultaneously, clorafin, propylene glycol play slow releasing function, promote absorption and the conversion of crop to the selenium element, can increase the content of organoselenium beneficiating ingredient in crop, increase its healthy nutritive value.

Embodiment

A kind of selenium-enriched fertilizer, made by the raw material of following weight part (kilogram): Sodium Selenite 5, diatomite 24, soil conditioner 10, clorafin 1, urea 12, weathered coal 20, humic acids 9, propylene glycol 4;

The preparation method of selenium-enriched fertilizer, is characterized in that adding Sodium Selenite, clorafin to stir the urea fusing, then, then adds other remaining component, mixes, and granulation, obtain

Described soil conditioner is made by the raw material of following weight part (kilogram):

Vermiculite power 12, attapulgite 25, zinc sulfate 1, Sodium Selenite 2, manganous sulfate 2, sal epsom 5, nano-sized carbon 0.4, clay 10, white lime 3, wintergreen oil 4, boric acid 3, tripoly phosphate sodium STPP 4, Silane coupling agent KH550 2, lapis amiridis 1, Paris white 4, water are appropriate;

Preparation method: after zinc sulfate, Sodium Selenite, manganous sulfate, sal epsom, nano-sized carbon mix, add wintergreen oil to stir, then, add again other remaining component except Silane coupling agent KH550, Paris white, be mixed into the mud shape, finally, add Silane coupling agent KH550, Paris white stirring-granulating, dry and get final product.

The present invention topdresses for wheat, corn etc., uses the 3-4 kilogram for every mu, and wheat can increase production 20-30%, and corn can increase production 15-20%, has good effect.After testing, in wheat, organic selenium content reaches 600-900 microgram/100 grams.
