摘　　要：试验开展了播种期与播种量对攀西蓝花子产种量影响的研究,结果表明:在同一播种期下,播种量为22.5kg/hm^2产种量>15kg/hm^2产种量>30kg/hm^2产种量;在同一播种量下,10月5日播种的产种量>9月15日播种的产种量>10月25日播种的产种量。本地区最佳播种期与播种量组合为10月上旬,播种量22.5kg/hm^2为宜,其产种量可达1 344.05kg/hm^2,显著高于其他水平。The effects of sawing date and rate on seed production of Panxi Raphanus sativus L. var. raphanistroides Makino was stud- ied in this paper. The results showed that the order of sawing rate for seed production in the same saw date level is： 22.5 kg/hm2 〉 15 kg/ hm- 〉30 k, hm2. And the seed production of sawing on October 5th 〉 sawing on September 15th 〉 sawing on October 25th in the same saw rate. The best schemes are sawing 22. 5 kg/hm2 on October 5th, the seed yield are 1344. 05 kg/hm2 , are significantly higher than the other grnups.
