在旱作条件下，研究了播种量和种植密度对胡麻产量、品质和农艺性状的影响，结果表明，播种量对胡麻产量有较大影响，种植密度对胡麻产量的影响较小，旱地胡麻种植的最优组合为播种量900万粒/hm2，行距20 cm，株距20 cm。胡麻的分茎数和单株生产力随播种量的减少而增加，且有利于株高和工艺长度的增加。

A natural dry farming conditions was conducted to investigate the effects of seeding rate and planting density on yield, quality and agronomic traits of oil flax . The results indicated that seeding rate influenced the yield of oil flax significantly， while there was little effect of planting density on yield . The optimal combination of dryland flax planting as following: row spacing 20 cm， sowing rate 9 00 ten thousand grain/hm2， plant spacing 20 cm . The stem per plant and productive force of individual plant rise along with the reducing of seeding rate， which also benefit the increase of plant height and technical length .
