Optimization of formula of walnut shell wood vinegar plant growth enhancer by response surface method
In order to optimize the formula of plant growth promoters with walnut shell wood vinegar,based on single factor test,taking walnut leaf area as response value,response surface method was used to detect the growth promo-tion effect of different mixture proportions on walnut.The results showed that when the volume fraction of wood vin-egar,the mass concentration of KH2 PO4,the mass concentration of superphosphate,the mass concentration of boric acid,the mass concentration of urea was 0.5%(200-fold liquid),0.2%,1%,0.2%,and 0.3%,respectively,the leaf area of one-year-old walnut was the largest,reaching 82.77 cm2,which had no significant difference from the predicted value(85.23 cm2).It showed that the growth promoting condition was the best.In the regression equa-tion,walnut shell wood vinegar had the most significant effect on the leaf area,which can be used for further prepara-tion of walnut shell wood vinegar plant growth enhancers.
