COMPOSITE FOLIAGE SI FERTILIZER FOR LOWERING CONTENTS OF HEAVY METALS AND NITRATE IN VEGETABLE, AND PREPARATION METHOD THEREOF |
摘要 |
<p>Disclosed is a composite foliage Si fertilizer, which is Mo-SiO2 composite collosol containing SiO2 10-25% and Mo ions 0.05-5.5% by mass, which is prepared by mixing uniformly active silicic acid solution with alkali Mo ion solution at 30-60°C, and reacting them under stirring. The composite foliage Si fertilizer can also be rare earth-Mo-SiO2 composite collosol containing SiO2 10-25%, Mo ions 0.05-5.5%, and rare earth ions 0.1-7.5% by mass. The composite foliage Si fertilizer can be used for lowering the contents of heavy metals and nitrate in a vegetable. The process has the advantages of simple preparation process, mild reaction condition, and suitability for mass production.</p> |
