As is clear from the analysis of the data in examples 23 to 25 and examples 21 to 22, when the weight ratio of carboxymethyl chitosan to hydroxyethyl chitosan was controlled to (1-3):2, the survival rate and disease and pest resistance of roses were high.
Analysis of the data of examples 26-28 and example 25 shows that the cutting shoots after 3-7 of growth are sprayed with the nutrient solution, the cutting shoots absorb the nutrient solution better, and the rose obtained by breeding has high survival rate and disease and pest resistance.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
