摘　　要：以豆科牧草红三叶和禾本科牧草高羊茅种子为对象,研究不同包衣材料、粘合剂以及不同药种比对两种牧草种子发芽特性的影响,为包衣材料的科学筛选提供理论依据。结果表明,当红三叶种子使用蛭石作为包衣、高羊茅种子使用蛭石+滑石粉作为包衣材料时均表现出较好的发芽特性,而使用泥炭、石膏、氢氧化钙作涂层材料则表现出较差发芽特性。使用8%聚乙烯醇作为粘合剂改善了红三叶种子的累计发芽率和50%发芽率所需天数。使用8%聚乙烯醇、1.5%羧甲基纤维素钠、CF-clear均能改善高羊茅种子的发芽特征。由此可知,以蛭石+滑石粉为包衣材料时,两种种子均表现最佳的发芽特征。8%聚乙烯醇、进口CF-clear是发芽效果最好的粘合剂。包衣倍数为3、5、7倍时两种种子的发芽效果好于对照组。The experiment was conducted to evaluate the effect of different coating materials, adhesives and pharmacopoeia ratio on the germination characteristic of red clover and tall fescue seed. The results showed that red clover and tall fescue showed excellent germination property with vermi- culite, vermiculite ＋talc coating, respectively, while they showed poor germination property with peat- moss, plaster, calcium hydroxide coating. By using 8% polyvinyl alcohol as adhesive, the cumulative germination percentage and the days to reach 50% of final germination had been improved respectively in red clover. The germination property of tall rescue were all good with 8% polyvinyl alcohol, 1.5% sodium carboxy methyl cellulose, CF-clear coating. It concluded that, in the case of seed emergence it was high with vermiculite ＋ talc coating and all the coating treatments showed higher value of final emergence percent than that of the control. For adhesives, 8% polyvinyl alcohol and CF-clear show good emergence. The treatments of 3,5,7 times of seed weight all showed better germination effect than the control group.
