以陇亚10号为指示品种，研究了播期对胡麻田杂草发生以及对胡麻产量的影响，结果表明：在播种量为60 kg/hm2时，播期对露地胡麻田杂草发生程度具有显著影响，播期越晚杂草发生越轻；播期对露地胡麻产量也有显著影响，播期越晚产量越低。综合杂草发生程度与胡麻产量，兰州地区的胡麻适播期以为4月2日前后为宜。

Longya 10 as indicator species,influence of sowing date on weeds occurrence in linseed field and yield of linseed are conducted . The result shows that the sowing date had significant influence on weeds occurrence degree in linseed field . The more late sowing date,the lighter the weed occurrence. The sowing date had significant influence on yield of linseed. The more late sowing date,the lower the yield of linseed . Based on weeds occurrence and linseed yield,the suitable sowing date of linseed in the Lanzhou area is around April 2 th,sowing during the period had little effect on yield of linseed,but can effectively reduced weeds occurrence degree,thus reducing the use amount of herbicide and is conducive to protect ecological environment.
