4), sal epsom (MgSO
4), manganous sulfate (MnSO
4) and ammonium molybdate (NH
4)
2MoO
4In container, mix, be injected into after being dissolved in water in the container that nitrogen, phosphorus, potassium mixed solution are housed, add tin anhydride (SeO after stirring again
2), the pH value of its mixed solution is 5.0～5.5, and forms comprehensive mixed solution.
The 3rd step: with borax (Na
2B
4O
710H
2O) join in 60～70 ℃ the hot water and dissolve, treat to join again in the comprehensive mixed solution after the water cooling.
The 4th step: with ammoniacal liquor (NH
3) comprehensive mixed solution regulated make its pH value reach 6.0～6.5, then make selenium liquid compound fertilizer.
Selenium liquid compound fertilizer provided by the present invention has following characteristics:
1. the main source of people, animal supplement selenium is water, soil and farm crop, is the usual channel that human body is mended selenium by food chain.The source of selenium of the present invention is to add the bigger tin anhydride of solubleness, and it is a byproduct of smelting non-ferrous metal, rather than Sodium Selenite.Because Sodium Selenite is to be raw material with the tin anhydride, behind chemical reaction, prepare, so the price of Sodium Selenite is 3 to 4 times of tin anhydride.Solution is subacidity (pH value 4.5～5.0) when adding tin anhydride in addition, can prevent the hydrolysis of elements such as copper, zinc, magnesium, manganese, generates precipitation, so tin anhydride is for mending the good additive of selenium.
2. farm crop not only can be increased production at heading flowering Spraying Se in season liquid composite fertilizer, and pass through the selenium content of the absorption raising crop and fruit of cauline leaf, reach normal geographic standard.In 0.08～0.10 μ g/kg scope, make the daily meals selenium intake of human body remain on 50～250 μ g as the grain selenium content.Be noted that farm crop are converted into organoselenium with the inorganic selenium fertilizer that absorbs and are stored among the fruit.Organoselenium is that human body absorbs easily, and safe and reliable again.Can not produce and poison because oral administration of sodium selenite tablet or selenium salt method are improper.So selenium liquid compound fertilizer is the new-type fertilizer of increasing crop yield, rich selenium, raising human body selenium level.Can increase production 12～35%, selenium content of crops increases by 6～20 times.
