摘  要:
为了优化宁南地区常见树种扦插技术,为其大面积生产推广提供科学育苗技术指导,研究不同浓度的ABT1号生根粉和国光生根粉对宁南地区几种常见树种插穗愈伤组织形成时间、发根时间、发根数、平均根长以及成活率的的影响,结果表明:ABT1号生根粉100mg/kg和国光生根粉的4 500 mg/kg对毛白杨和新疆杨硬枝扦插有明显的促进作用,ABT1号生根粉150 mg/kg和国光生根粉6 500 mg/kg对臭椿和白蜡硬枝扦插有明显的促进作用,比清水处理及其他处理差异明显。低浓度和高浓度处理对硬枝扦插有抑制作用,并且国光生根粉的最佳浓度处理要比ABT1号生根粉的最佳浓度处理效果略好。由于树种本身的差异,毛白杨和新疆杨硬枝扦插生根明显要比臭椿和白蜡生根容易,成活率高。

摘  要:
In order to improve cutting technology and provide seedling guidance for production of several main tree species in Southern Ningxia area,effect of different concentrate of ABT1 and Guoguang rooting powder on callus forming time,rooting time,root number,mean root length and survival rate were studied.The results showed that the concentrations 100 mg/kg of ABT1 and 4 500 mg/kg Guoguang rooting powder had obvious promoting action on hardwood cuttage of Populus tomentosa and Populus bolleana.The concentrations 150 mg/kg of ABT1 and 6 500 mg/kg Guoguang rooting powder had obvious promoting action on hardwood cuttage of Ailanthus and Ash.Both high and low concentration inhibited hardwood cuttage.The optimum concentrate of Guoguang rooting powder was better than ABT1 rooting powder.Due to the difference in tree species,Populus tomentosa and Populus bolleana was easier rooted than Ailanthus and Ash.
