Abstract: In order to investigate the impact of organic fertilizer and biochar on dryland crop plantation and environment, a long-term field plot experiment was conducted to study the effect of combined application of organic and inorganic fertilizer with biochar on the change of soil nutrients, Chinese cabbage yield and quality and fertilizer utilization rate. The results showed that compared with chemical fertilization treatment, combined application of organic and inorganic fertilizer with biochar effectively increased the content of total nitrogen, available nitrogen, total potassium, available potassium, available phosphorus and organic matter by 0.52%, 1.46%, 0.44%, 19.65%, 1.58% and 30.31%, respectively. The utilization rate of nitrogen and phosphorus was increased by 195.35% and 307.3%. The contents of soluble sugar and amino acid in Chinese cabbage increased by 15.42% and 26.24%, and the yield increased by 74.37%. Therefore, the combined application of organic and inorganic fertilizer with biochar could effectively increase soil nutrient content, increase the accumulation of nitrogen and phosphorus in the aboveground part and improve the yield and quality of Chinese cabbage.
