通过试验设计,比较了不同生根促进剂种类、不同生根促进剂浓度对尾赤桉201-2扦插成活率的影响;分析了不同木质化程度的插穗及扦插基质对尾赤桉201-2扦插成活率的影响差异。结果表明,ABT-1#600 mg/kg对扦生根效果最好,成活率高且生根数多;半木质化的绿枝+70%的红心土和30%的粉河沙作为扦插基质效果最佳,平均成活率达90.8%,平均生根数18.3条,平均生根长16.7 cm。
Through the experimental design, the effects of different rooting accelerant types and different rooting accelerant concentrations on the cutting survival rate of Eucalyptus urophylla 201-2 were compared. The cutting and survival of Eucalyptus urophylla 201-2 were analyzed with different lignification degree cuttings and cutting matrices The impact of rate differences. The results showed that ABT-1 # 600 mg / kg had the best effect on rooting, high survival rate and rooting number. The semi-lignified green branch + 70% red heart soil and 30% pink river sand had the best effect on cutting rooting , The average survival rate of 90.8%, the average number of rooting 18.3, the average root length of 16.7 cm.
