Abstract:
Taking Brassica campestris L.ssp.Chinensis as material，the pot experiment was conducted to study the effects of combined application of nitrogen and potassium fertilizers on yield and quality of Chinese cabbage.The results showed that with the nitrogen application of 100 mg/kg，the yield and chlorophyll content of Chinese cabbage were the highest，but yield and chlorophyll content were decreased at 200 mg/kg.The content of nitrate nitrogen was increased with increase of nitrogen application rate；but it was contrary for content of vitamin C and soluble sugar of Chinese cabbage.The yield，content of chlorophyll，vitamin C and soluble sugar of Chinese cabbage were increased with increase of potassium application rate，and content of nitrate nitrogen decreased.The yield of N2K3（N 100 mg/kg，K 300 mg/kg）combination was the highest；N1K3（N 50 mg/kg，K 300 mg/kg）combination was the most suitable for quality.Summarized above results，it found that the optimal combination of nitrogen and potassium to obtain Chinese cabbage with high yield and quality was 50~100 mg/kg nitrogen together with 200~300 mg/kg potassium.
