摘要

[目的]对不同生根剂对假俭草茎段撒播生根效应的影响进行研究，为假俭草做为水土保持植物快速建植提供合理有效的技术指导。[方法]从茎段撒播技术中的茎段生根关键环节开展试验，比较不同生根剂对假俭草生根茎段比例、生根时间和成活率的影响，以确定最佳生根剂和处理方式。[结果]吲哚丁酸（100 mg/L）对假俭草撒播茎段的生根效率、缩短生根时间和成活率效果最佳；覆盖无纺布对提高假俭草茎段生根效率和缩短生根时间有显著作用，但是对假俭草茎段成活率没有显著影响。[结论]不同生根剂对假俭草茎段生根速率具有显著影响，其中效果最好的是吲哚丁酸。

Abstract

[Objective] The effects of different rooting agents on the rooting performance in sowing of stem segments of Eremochloa ophiuroides were studied in order to provide reasonably and effectively technological guidance for Eremochloa ophiuroides' function for soil protection and fast growth plantation.[Methods] Focused on some key experimental aspects in sowing of stem segments

the ratio of rooted stem to sowed stem

rooting time

and survival rate of Eremochloa ophiuroides were measured under different rooting agents treatments to select the best rooting agent and methods.[Results] In terms of rootage efficiency

the reduction of rooting time and survival rate

the indolebutyric acid(IBA

100 mg/L) was the most efficient rooting agent for sowing of stem segments of Eremochloa ophiuroides. Fabric covering also played a vital part in promoting the rooting efficiency and rootage time reduction after sowing

while there was little effect on the ratio of survival.[Conclusion] Different rooting agents have significant effects on the sowing of stem segments of Eremochloa ophiuroides

indolebutyric acid is the best among them.
