specific Embodiment approach 1
[0010] Embodiment 1: The composition and mass percentage of this embodiment are: polyglutamic acid 40%, chitosan oligosaccharide 60%.
[0011] The preparation method is: uniformly mixing polyglutamic acid and chitosan oligosaccharide in proportion.
[0012] This specific embodiment adopts polyglutamic acid and chitosan oligosaccharide, mixes evenly according to the ratio, every 667m 2 , 15,000-20,000 times the water, sprayed on the plant surface before the disease occurs, for the prevention and treatment of cucumber downy mildew, tomato gray mold and other fungal diseases.
[0013] This specific embodiment adopts a reasonable ratio of two kinds of biological substances, which are not easy to be hydrolyzed after use, and are more easily absorbed by plants after spraying on vegetables, so as to quickly induce plant resistance, and finally achieve the effect of strong plant growth and disease resistance.
specific Embodiment approach 2
[0014] Embodiment 2: This embodiment differs from Embodiment 1 in that its composition and mass percentage are: polyglutamic acid 35%, chitosan oligosaccharide 65%, and its preparation method is the same as Embodiment 1.
specific Embodiment approach 3
[0015] Embodiment 3: This embodiment differs from Embodiment 1 in that its composition and mass percentage are: polyglutamic acid 65%, chitosan oligosaccharide 35%, and its preparation method is the same as Embodiment 1.
