对2种引进树种牛蹄豆(Pithecellobiumdulce)和智利牧豆(Prosopis chilensis)的扦插繁殖技术进行了研究。结果表明不同激素的不同浓度对于2树种的插条生根大都具有促进作用,具体表现在生根率增加、生根根数增多、最长根长增长等方面。低浓度具有明显的促进作用,而浓度过高则表现出负效应。适宜的激素组合比一种激素处理效果更为明显。扦插2个月后,牛蹄豆直接扦插的生根率达到60%,但IBA2 000 mg/L+NAA2 000 mg/L处理可以将生根率显著提高到90%;智利牧豆直接扦插的生根率仅有5%,而IBA1 000 mg/L处理可以将生根率极显著提高到57.50%。
The cutting propagation techniques of two introduced species, Pithecellobium dulce and Prosopis chilensis, were studied. The results showed that different concentrations of different hormones promoted the growth of 2 kinds of cuttings, especially in the aspects of increasing the rooting rate, increasing root number, and increasing the longest root length. Low concentrations have a significant role in promoting, while the concentration is too high, showing a negative effect. The appropriate hormone combination is more effective than a hormone treatment. After two months of cutting, the rooting rate of direct cuttage of the legumes reached 60%, but the rooting rate of the cuttings of D. officinale significantly increased to 90% when treated with IBA 2000 mg / L + NAA 2000 mg / L. 5%, IBA1000 mg / L treatment can significantly increase the rooting rate to 57.50%.
