摘　　要：目的:探讨播期、密度、施肥等栽培措施对白芷产量的影响。方法:采用称重法测定白芷产量。结果:4月20播种的白芷产量最高为8373 kg/hm2,与4月5日和5月5日播种的白芷比较差异显著;密度为33万株/hm2的白芷产量最高达9300 kg/hm2,与26万株/hm2和38万株/hm2的白芷比较差异显著;施肥量为N30P24,N24P20和N18P16的白芷产量均高于对照,且差异显著。结论:白芷适宜播期为4月上中旬,适宜密度为33万株/hm2,适宜施肥量为N24P20(纯氮360 kg/hm2、P2O5300 kg/hm2)。Objective ： To evaluate the effect of seedingtime, density of crop and fertilization on the yield of Angelica dahurica. Method ： Use weighing method to measure the output of A. dahurica. Result ： The highest yield of seeding-time is 8373 kg/hm^2 on April 20, which is considerably different compared with April 5 and May 5 ; the highest yield of the density is 9300 kg/hm^2 on 330,000 plants/hm^2 ;the yield of fertilization tests all are considerable higher than that of the contrast. Conclusion： The appropriate seeingtime of A. dahurica is the first or second ten days of April, the appropriate density is 330,000 plants/hm^2 , and the appropriate amount of fertilization is N24P20, i. e pure N 360kg and P2O5 300kg per hectare.
