摘要: 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16.7cm。

Abstract: Comparative experiments were conducted on different types of root taking promoters and their individual effects on the survival rate of Eucalyptus urophylla×Eucalyptus camaldulensis clone DH201-2 cuttings. Analysis was done on the effects of the cuttings with different lignification degrees and cuttage media on the cutting survival rate of Eucalyptus urophylla×Eucalyptus camaldulensis clone DH201-2. The results indicated that ABT-1# 600 mg/kg is best for root taking and the survival rate and number of roots are high. Half lignification's green branches +70% red subsoil and 30% fine river sand make the cuttage matrix effect best, the average survival rate reaches 90.8%, averages number of roots 18.3 and the average root length 16.7cm.

Key words: Eucalyptus urophylla×Eucalyptus camaldulensis clone DH201-2, cuttings, survival rate
