Example Embodiment
[0010] Specific embodiment 1: The composition and mass percentage of this specific embodiment are: polyglutamic acid 40% and chitooligosaccharides 60%.
[0011] The preparation method is as follows: the polyglutamic acid and the chitosan oligosaccharide are mixed uniformly according to the ratio.
[0012] In this specific embodiment, polyglutamic acid and chitosan oligosaccharides are mixed uniformly according to the ratio, and each 667m 2 , 15000-20000 times the water, sprayed on the surface of the plant before the disease occurs, used to control cucumber downy mildew, tomato gray mold and other fungal diseases.
[0013] This specific embodiment adopts a reasonable ratio of two biological substances, which is not easy to be hydrolyzed after use, and is easier to be absorbed by plants after spraying on vegetables, and quickly induces plants to develop resistance, and finally achieves the effect of strong plant growth and disease resistance.
Example Embodiment
[0014] Specific embodiment two: This specific embodiment is different from specific embodiment one in that its composition and mass percentage are: polyglutamic acid 35%, chitosan oligosaccharide 65%, and its preparation method is the same as specific embodiment one.
Example Embodiment
[0015] Specific embodiment three: This specific embodiment is different from specific embodiment one in that its composition and mass percentage are: polyglutamic acid 65%, chitosan oligosaccharide 35%, and its preparation method is the same as specific embodiment one.
