【摘要】 通过正交试验设计研究不同生根促进剂和浓度处理不同木质化程度的厚荚相思穗条对扦插繁殖生根率、生根数、生根长度及苗高的影响;研究了不同基质对厚荚相思扦插生根的影响差异,还研究了不同时间扦插对厚荚相思生根率的影响。结果表明,嫩枝使用450 mg.kg-1ABT 1#+450 mg.kg-1IBA生根率高,生根数多;3种基质对比试验中以100%红心土生根率最高;不同时间扦插中以4~6月份生根率最高。更多还原

【Abstract】 The results showed that the rooting rate was high,rooting number was high,the root was long,and seedling was tall with applying 450 mg·kg^-1ABT1^#+450 mg·kg^-1IBA to the new branch;the rooting rate was highest with 100% of red subsoil in the experiment of comparison between 3 kinds of substrates;the rate of cutting in different time was highest during Aug.～Jun.更多还原
