摘要 在浙江诸暨按麻疯树(Jatropha curcas)2种不同种源、ABT处理、木质化程度、插穗长度、扦插时间、扦插基质和叶片保留程度等不同因素进行扦插育苗试验。结果表明,影响麻疯树扦插成活率的主要因素为插穗木质化程度及种源;当年生嫩枝易于生根,2种种源各处理扦插成活率均能保持在75%以上,经浙江诸暨引种栽培的麻疯树枝条作为插穗进行扦插时,当年生嫩枝或2年生硬枝扦插成活率均能保持在70%以上;浙江诸暨种源截取30 cm左右保留少量小叶的当年生嫩枝作插穗,经1 000 mg/L的ABT处理后扦插在含沙土的苗床中,其扦插成活率可达95%。 Experiments on seedling cultivation of Jatropha curcas were carried out in Zhuji, Zhejiang province with different provenances, ABT treatments, lignification degrees and length of cuttings, date of cuttage, cutting mediums and leaves kept. The result showed that ligniflcation degree and provenance was the most important factor for survival rate of cuttings. Current year softwood had advantage of easier rooting. Survival rate of each treatment was-more than 75%. Seedlings by branch cuttings of J.curcas introduced to Zhuji had survival rate of over 70%. The best treatment for J, curcas cutting was as follows, current year softwood of 30 cm new shoots with leaves, treated by ABT of 1000 mg/L. The survival rate could reach 95%.
