Abstract:

【Objective】 The effects of different nutrient solutions on the morphological and physiological indexes of cut chrysanthemum cv. Jinba cutting plants were studied. 【Method】 416-A optimization compound design was used, and CCC, sucrose, oligopeptides, urea were the chief components in this experiment.【Result】 These indexes were improved obviously by spraying nutrient solutions as compared with the control. The treatments T10 and T9 got the highest values of dry weight and height, respectively, and significant difference was observed compared with the control. During the whole cutting period, the contents of soluble sucrose, protein and chlorophy in T1, T9, and T10 treatments were higher than the control, the content of soluble protein of T9 and soluble sucrose, chlorophy of T10 increased remarkably.【Conclusion】 The multiple element regression equation of dry weight and height was established in this study and can be used in decision-making and forecast, according to the r value 0.916, 0.907 and variance analysis. Based on the computer analysis and production experience, the optimization scheme obtained is CCC 5.9%, oligopeptides 7.9%, sucrose 4.95%, and urea 36.53%.
