Abstract：Taking Jinlai Qiubai 6 as test material,the effects of different planting densities,sowing dates and fertilization conditions on the agronomic traits of Chinese cabbage were studied in this paper.The results showed that the best planting density was in the range of 3 000 ~3 500 plants per 666.7m2 with the row spac-ing as 40 cm and the line spacing as 50 cm.The Chinese cabbage variety Jinlai Qiubai 6 could be planted from July to August whilst keeping higher yield.With the delay of sowing date,the growth period became lon-ger,and the incidence of viral diseases,downy mildew and soft rot disease decreased.The combined application level of N,P and K had important effects on the yield of Jinlai Qiubai 6.The yield increasing effect of N was larger than that of K,and that of P was the lowest.When the application rate of N,P and K was 1∶0.4∶0.8, the yield of Jinlai Qiubai 6 reached the highest.
