Abstract:
Effects of different proportions of combined application of chemical fertilizer with organic fertilizer on the yield and quality of Chinese kale were studied. The results showed that combined application of 40% organic fertilizer had highest yield, and which compared with pure chemical fertilizer and pure organic fertilizer treatments, increased by 10.29% and 21.59% respectively, and reached extremely significant level. Also under this treatment, the content of Vc and total soluble sugar in Chinese kale were the highest, and the nitrate content of Chinese kale reduced with the increasing of combined application ratio of organic fertilizer.
