摘要：

Cabbage (Brassica oleracea L.) was fertilized at rates of 0, 100, 200, 300, 400 and 500 kg N ha-1. Yield and plant total N increased with increasing N rate. Apparent recovery of fertilizer N in the cabbage heads averaged 32 % and was independent of N rate. Soil extractable inorganic N at harvest was low and increased with increasing N rate in only one of the 2 yr.
