The substantial amounts of hydroxyl in its surface provides abundant attachment site for selenium mineral powder, and can utilize the hydroxyl and bumps on its surface
The hydroxyl on stick clay surface, under itaconic acid and silane resin acceptor kh-550 modifying function, is combined more with compound fertilizer granule
Closely, and under the filming function of diethylenetriamine, adjacent Phenylbenzoic acid and polyvinyl alcohol, and in itaconic acid and silane coupling agent
Under the synergistic effect of KH-550, as the primary raw material of film feed liquid, effective sustained release to selenium element is realized, improves selenium
Element can efficiently carry out selenium element release when bacterial manure puts into use, and can the flora in compound fertilizer granule into
It can be slowly entered after entering into soil in soil, slowly supply beneficial bacterium is carried out to soil, avoids soil depletion and plate
Knot improves the efficiency and quality of plant growth, improves the content of crop selenium element, improves the yield and quality of crop.
More than content is it cannot be assumed that present invention specific implementation is confined to these explanations, for the technical field of the invention
Those of ordinary skill for, under the premise of present inventive concept is not departed from, several simple deduction or replace can also be made, all should
When being considered as belonging to present invention scope of patent protection determined by the appended claims.
