摘要：在冀西北坝上冷凉气候条件下，采用田间小区试验，比较了春冠、春冠35、春光、春辉、春雪圣和春蓄6个萝下品种对氮（N）、磷(P,0，）、钾(K,0)养分的吸收利用特性。结果表明，春冠35与春辉的肉质根产量最高，春雷圣最低。不同萝下品种各养分的累积分配特征及养分利用效应亦存在显著差异，春蓄的氮累积量最高，春冠35的磷累积量最高，春辉钾累积量最高，上述三品种的另外两种营养元素累积量亦显著高于其他三个品种，且各养分偏生产力表现突出；春光和春雪圣氮累积量最低，春冠的磷、钾累积量最低。养分生产效率和干物质生产效率以春光和春冠两个品种较高。综合评价可知，春辉、春冠35和春蕾为养分高效累积型品种，春雪圣为养分吸收利用低效率
品种，而春光和春冠则属于养分生理利用高效率品种。关键词：冀西北；萝卜；品种：生物量；养分

Abstract: A field experiment was conducted to study the nutrients absorption characteristics of six radish varieties in the northwest area of Hebei province, The results indicate that the root yields of the varieties, Chun Guan 35 and Chun hui are the highest, and the yield of Chun xue-sheng is the lowest, There are significant differences among the N, P and K accumulations and distributions in different radish varieties, the varieties of Chun lei, Chun guan35 and Chun hui have the largest accumulations of N, P,O, and K,O, respectively, and the accumulations of the other two nutrients and as well as the PFP are also higher than those of the other three varieties; The N accumulations of Chun guang and Chun xue-sheng are the lowest and the accumulations of P,O, and K,O of Chun guan are the lowest. The varieties of Chun guang and Chun guan have higher production efficiency of nutrients and dry matter. In conclusion, Chun hui, Chun guan 35 and Chun lei have high nutrients use efficiencies, while Chun xue-sheng has low nutrients use efficiencies, and Chun guang and Chun guan have higher physiological use efficiencies of the nutrients.
