Abstract:In order to increase the diversity of post-wheat multiple-feed rapeseed in Ningxia Yellow River Irrigation Area, Fuyou 128 (P1), Fuyou 158 (P2), Ningza 19 (P3), Jinyouza 158 (P4) and Huayouza 62 ( P5, control)was studied in this study. Through field trials, the plant height, stem thickness, SPAD value, dry weight per plant, plant nitrogen, phosphorus and potassium nutrient content and nutrient accumulation, forage yield of the five rapeseed varieties were treated by use of the same sowing rate. The results showed that: at harvest, there was no significant difference between P4 dry weight per plant and P5; plant height, stem thickness, SPAD value of P4, P3, P2 and P5 were not statistically significant; nitrogen, phosphorus and potassium nutrient content during rape growth were decrease, but the cumulative amount of nutrients continue to increase; under this test condition, P1 had the lowest fresh grass yield at 46 200 kg/hm2, P5 had the highest fresh grass yield at 57 200 kg/hm2 , the fresh grass and hay yields of P3 and P4 were not significantly different from P5. Comprehensive analysis, P4, P3, P2 can be popularized in Ningxia Yellow River Irrigation Area.
