采用二因素裂区设计，以保水剂和活性炭、硅藻土、凹凸棒为填充剂的包衣材料制作丸粒化胡麻种子，研究了丸粒化处理对胡麻种子萌发和幼苗生长的影响。结果表明：与不加保水剂相比，保水剂质量与种子质量为1∶1时，丸粒种子的活力指数和出苗率显著提高20．11％、18．62％；随着保水剂含量的增加，幼苗的根冠比显著减小3．25％。包衣剂中以活性炭：凹凸棒＝1∶1为填充剂的发芽率和出苗率比不加填充剂的明显提高6．79％、22．41％，幼苗生长最健壮。与未丸粒化的种子相比，当保水剂质量与种子质量为1∶1时，以活性炭：凹凸棒＝1∶1为填充剂的丸粒种子发芽指数、活力指数和出苗率显著提高，而且幼苗的茎粗、叶面积和根冠比分别显著增加11．02％、27．35％、28．07％。可见，适量的保水剂（保水剂质量与种子质量为1∶1）和以活性炭、凹凸棒为填充剂的包衣剂能提高胡麻种子活力，增加出苗率，使幼苗的干物质重增大，根系发达，根冠比提高，为胡麻高产奠定了良好的基础。

To clarify the pelleting effect on seed germination and seedling growth ,a split - plot experiment of two factors was conducted to generate pelleted flax seeds using absorbent ,active carbon ,diatomite ,and attapulgite as coating materials .When the ratio of absorbent to seed was 1∶1 ,the vigor index and seedling germination rate of pelleted seeds were significantly increased by 20 .11% and 18 .62% more respectively than those without the addition of absorbent . With the increase of water content ,root shoot ratio was decreased by 3 .25% .The germination rate and emergence rate of pelleted seeds with active carbon and attapulgite (ratio 1∶1) were increased by 6 .79% and 22 .41% more respectively than those without any filler ,resulting in the healthiest seedlings .When the ratio of weight of absorbent to seed was 2∶1 , the use of activated carbon and attapulgite (the ratio was 1∶1) as filler could significantly improve the germination index , vigor index and seedling emergence rate .Furthermore ,the stem diameter ,leaf area and root shoot ratio of seedlings were significantly increased by 11 .02% ,27 .35% ,and 28 .07% .Therefore ,coating agent using appropriate amount of ab-sorbent (ratio of weight of absorbent to seed was 1∶1) ,activated carbon and attapulgite as fillers had better effects on flax seeds by improving the seed vigor and increasing the rate of emergence ,seedling dry weight ,root system ,and root shoot ratio ,which laid a good foundation for flax yield .
