Effects of two kinds of zinc fertilizer on growth of Chinese flowering cabbage

500 mg/L，1000 mg/L and 1500 mg/L of zinc sulfate and 86 mg/L of Hefeng zinc were sprayed on the leaves of Chinese flowering cabbage（Brassica aff parachinensis Bailey），and influences of two kinds of zinc fertilizer on growth，production and quality of Chinese flowering cabbage were studied. The results showed that suitable concentration of Hefeng zinc could promote the growth，improve the content of chlorophyll，increase the flowering cabbage production and improve the quality，as the economic output could up to 16.13 g，which was 2.61 times compared to the control group，also the Vc content was up to 125.49 mg/100g，which was 1.36 times compared to the control group. While， different zinc sulfate concentrations also effected the growth of Chinese flowering cabbage，1 000 mg/L of zinc sulfate treatment had the best effect，as the soluble protein content was 17.45 mg/g，which was 1.22 times compared to the control group. 500 mg/L and 1 500 mg/L of zinc sulfate treatment also promoted the growth，but had little effect
