Abstract: Different fertilization treatments were set up to study the effects of different fertilization modes on the yield, quality and nutrient utilization rate of the radish (Raphanus sativus L.)-cabbage (Brasscia oleracea L.) rotation system in the alpine region of western Hubei Province with conventional fertilization as control. The results showed that compared with the conventional fertilization control, the yield of radish increased by 11.09% and 38.59% in the treatment of optimized fertilization and organic fertilizer replacing 30% of chemical fertilizer nitrogen, respectively, and in addition to the recovery efficiency of potassium in the optimized fertilization treatment, the recovery efficiency, agronomic utilization rate, partial productivity and harvest index of nitrogen, phosphorus and potassium in the two treatments increased to varying degrees. Compared with the conventional fertilization control, the application amount of phosphate fertilizer and potassium fertilizer in the optimized fertilization model decreased by 50.00% and 16.67%, respectively, but the yield of cabbage decreased by only 1.68%, and except for the decrease of nitrogen agronomic efficiency and partial factor productivity, the nutrient utilization efficiency indicators and harvest index of other nitrogen, phosphorus and potassium all increased. Compared with conventional fertilization, under the treatment of organic fertilizer replacing 30% of chemical fertilizer nitrogen, the yield of cabbage increased by 4.49%, the recovery and utilization rate, agronomic utilization rate and partial productivity of nitrogen and potassium, the agronomic utilization rate and partial productivity of phosphorus all increased. Therefore, the mode of optimized fertilization and the mode of organic fertilizer replacing 30% chemical fertilizer nitrogen had a significant effect on improving the yield and nutrient use efficiency of the alpine radish-cabbage rotation system in western Hubei Province.

Key words: radish (Raphanus sativus L.), cabbage (Brasscia oleracea L.), optimized fertilization, yield, quality, nutrient use efficiency, western Hubei Province
