Abstract

The invention relates to a high-adhesion jujube fruit shrink disease resisting emulsion and a preparation method of the emulsion. The high-adhesion jujube fruit shrink disease resisting emulsion comprises effective constituents (streptomycin, instant boron, berberine), adhesives (chitosan, sodium carboxymethyl cellulose (CMC-NA)-glycerin) and an emulsifier (tween 80). The preparation method comprises the following steps: mixing 1-4% of a chitosan solution (acetic acid solution) with 1% of a sodium carboxymethyl cellulose-glycerin solution according to the ratio of 1:(3-5) to prepare a high-viscosity solution, adding the effective constituents (according to that the ratio of streptomycin to instant boron to berberine is (2-4):(2-4):1) in the high-viscosity solution, then mixing the mixed solution with the emulsifier, dissolving at an ultrasonic condition, heating in water bath and stirring, at last obtaining the emulsion. The emulsion can strongly inhibit the jujube fruit shrink disease, aims to achieve high adhesion, rain-wash resistance, as well as toxic-free and environment-friendly effects, and has the advantages of stability, high efficiency and low cost.

Description

technical field [0001] The invention relates to a high-adhesion bactericide and a preparation method thereof, in particular to the preparation of a high-adhesion anti-jujube fruit shrinkage emulsion. Background technique [0002] Jujube is mainly distributed in Henan, Hebei, Shandong, Shaanxi, Shanxi, Xinjiang, Ningxia, Gansu, Liaoning and other places in China. Fruit shrinkage disease is one of the main fruit diseases in major jujube regions. The average rate of diseased fruit is 5-15%, and the rate of diseased fruit in individual plots is as high as 50%. The disease began to appear at the end of June, gradually increased in early July, entered the peak period in the middle and late ten days, and lasted until the first and middle ten days of September. From the perspective of the degree of damage, the early onset (end of June-early July) in the garden, the whole diseased fruit is thin and falls off early, which seriously affects the yield of jujube. However, because the c...
