Effects of Four Functional Fertilizers on Growth and Quality of Flowering Chinese Cabbage
To screen the functional fertilizers suitable for the cultivation of flowering Chinese cabbage,this study explored the effects of four different types of functional fertilizers on the growth and quality of flowering Chinese cabbage.These fertilizers included PSO4 fermentation broth(PSO4),corn extract(CE),hydrolyzed feather powder(HFP),and inositol powder(IN).The results showed that an appropriate amount of four functional fertilizers could significantly increase the yield of flowering Chinese cabbage,with an order of increasing rate of IN＞HFP＞PSO4＞CE.The HFP and IN promoted the lateral growth of flowering Chinese cabbage roots.PSO4 solution promoted the longitudinal growth of the root and significantly increased the contents of soluble solids,soluble sugar,and vitamin C,thus improving the quality of flowering Chinese cabbage.In flowering Chinese cabbage cultivation,the optimum concentration of PSO4 and CE is 300 times diluted,the optimum concentration of HFP is 0.05％,and the optimum concentration of IN is 0.1％.These research results provide a theoretical basis for the application of these four functional fertilizers in the production and quality cultivation of flowering Chinese cabbage.
