金叶刺槐不同扦插育苗方式对生根率影响的研究

摘要

Cuttage seedling-raising experiments of Robinia pseudoacacia were conducted with three matrices (vermic-ulite ,perlite and sand) and CK ,three kinds of rooting accelerator (NNA ,IBA ,ABT ) ,three kinds of concentration (50 ,100 ,200 mg·L-1 ) ,three kinds of treating time (2 ,6 ,12 h) .Result shows that :the softwood cuttings of Robinia pseudoacacia were cut by taking vermiculite or perlite as cutting medium ,cuttings with four to five leaves ;the cut-ting was treated with ABT rooting powder ,with the concentration being 100 mg·L-1 ;the treating time is from six to eight hours ,which can reach an ideal nursery effect .%通过对金叶刺槐（RobiniapseudoacaciaAurea）进行蛭石、珍珠岩和河沙等3种基质，NNA、IBA、ABT等3种生根促进剂，50、100、200mg·L-1等3种浓度，2、6、12h等3种处理时间的扦插育苗试验，结果表明：金叶刺槐采用嫩枝扦插方法进行繁殖时，以蛭石或珍珠岩作扦插基质，插穗带4～5片叶片，插前用ABT生根粉进行催根处理，浓度为100mg·L-1，处理时间为6～8h可达到较理想的育苗效果。
