Abstract: This article designed five groups by taking "Xingyiheqiu" Chinese cabbage planted in Ningxia as the research object. The five groups were 345 kg·hm-2 nitrogen fertilizer（CK, conventional fertilization）, 37.5 kg·hm-2 nano-fertilizer additives+345 kg·hm-2 nitrogen fertilizer（T1）, 75 kg·hm-2 nano-fertilizer additives+300 kg·hm-2 nitrogen fertilizer（T2, reduced nitrogen 13%）, 112.5 kg·hm-2 nano-fertilizer additives+255 kg·hm-2 nitrogen fertilizer（T3, reduced nitrogen 26%） and 150 kg·hm-2 nano-fertilizer additives+210 kg·hm-2 nitrogen fertilizer（T4, reduced nitrogen 39%）, respectively. These treatment groups were set up to explore the effects of the mixed application of nano-fertilizer additives and nitrogen fertilizer in irrigated silt on the growth, yield, quality and soil enzyme activity of Chinese cabbage. The results showed that compared with CK, the dry matter quality, plant height, outer leaf number, longitudinal diameter, transverse diameter, plant weight and yield of Chinese cabbage increased by 1.22%～6.31%, 1.67%～4.80%, 6.98%～15.90%, 12.19%～56.60%, 1.22%～25.91%, 0.68%～27.89% and 3.98%～32.24%, respectively. The soluble solids increased by-2.49%～1.88% for Chinese cabbage. There was no obvious differences between different treatments in the content of soluble sugar and Vc. The nitrate content and alkaline phosphatase decreased by 2.46%～4.54% and 5.61%～18.36%. While, the catalase, urease and sucrase in the soil increased by 1.72%～13.79%,-25.65%～1.07%, and 11.99%～18.80%, respectively. At the same time, compared with CK, the SPAD values at seedling stage and mature stage in different treatments had no significantly different. But, there was a certain difference for the SPAD values in the outer and middle leaves at the rosette stage, the early and late heading stage. The SPAD value could reach the peak in the early and late heading stage. Above all, the T2 treatment was the best group by combining the factors in the mature period of Chinese cabbage. The application of nitrogen-reducing fertilizer 13%+75 kg·hm-2 nano-fertilizer additives was more suitable for the growth and yield increase for Chinese cabbage on the irrigation soil in Yinchuan Plain.
