A grass streptomyces, grass streptomyces microcapsule and a preparation method and application thereof

Abstract

The present application provides a kind of grass streptomyces, grass streptomyces microcapsule and its preparation method and application.The grass streptomyces microcapsule of the present application uses the spore of streptomyces as capsule core, adopts multilayer composite wall material structure, the gel layer of inner layer capsule wall is formed by sodium alginate-calcium ion crosslinking, the functional polymer layer of outer layer capsule wall has charge or chemical action with inner layer capsule wall, outer layer is environment response type material, structural change occurs under the action of soil moisture, pH value or rhizosphere biological enzyme, thereby triggering the gradual release of streptomyces, can be triggered according to the change of soil moisture, pH or rhizosphere biological enzyme release, realize the controllable release of streptomyces, the synergistic effect of multilayer wall material prolongs the effective action time of grass streptomyces in soil, improves the fertilizer efficiency persistence;The grass streptomyces microcapsule of the present application has the effect of promoting tea growth, improving tea yield, improving tea germination density and hundred bud weight.
