摘要
对２６种亚热带生长的扦插难生根的针叶树种和阔叶树种用不同的采穗时间（１２月，２～３月，６月），不同的药剂处理（ＡＢＴ－１，ＮＡＡ，ＩＢＡ，清水）和不同的贮藏时间（沙藏２个月后插，即插）进行促进插穗生根的试验，结果表明：促使６０％的树种生根率达到２５％以上，３０％的树种生根率达５０％以上，约２０％的树种生根率达８０％以上。药剂处理以ＡＢＴ生根粉效果最好。落叶树种，以冬季采休眠枝，用药剂处理后沙藏至早春扦插为好。常绿阔叶树，以６月采穗，用药剂处理后即插为好。
The cuttings from 26 subtropical tree species were gathered atvarious seasons(December,Febrary,March and June),treated with differentroot-promoting chemicals(ABT-1,NAA,IBA and water),and planted atvarious dates(immediately planting the cuttings after treatments and plantingthe cuttings after storage for two months in moist sand).The results showedthat the striking root percentage 60% of the tested tree species were above25%,30%of above 50%and about 20%of above 80%.The best effect wasobtained from ABT-1 treatment.To gather hardwood cuttings in winter,totreat cuttings with growth regulators before storage for two months in moistsand and to plant in early spring were preferable for deciduous tree species.To gather cuttings in June and plant cuttings immediately after regulatortreatments could obtain higher rooting percentage for broadleaved evergreen species.
