Effects of different concentrations of molybdenum fertilizer on yield and quality of Chinese cabbage

Taking Chinese cabbage as test materials，the effects of different concentrations（ 0，0.50， 0.67，1.00，2.00 mL/L） of molybdenumon ferlilizeron the yield and quality were studied，and the concentration of molybdenum fertilizer suitable for Chinese cabbage was screened out. The leaves were sprayed with different concentrations of Hefeng molybdenum at 21 and 28 days after sowing， physiological and biochemical indicators at 19，26 and 33 days after sowing were separately measured. The results showed that: when the concentration of molybdenum fertilizer was 0.67 mL/L，the fresh weight，leaf area and soluble sugar content increased，extremely increase Vc，nitrate content decreased，but the effect of molybdenum on protein and chlorophyll content was less. Combined with economic and environmental factors，0.67 mL/L molybdenum treatment had the best effect on Chinese cabbage.
