优良堤防护坡植物假俭草草茎建植方式的比较研究

采用3种草茎建植方式进行了野生假俭草无性繁殖的对比试验研究。结果表明：开沟植茎、草茎扦插两种建植方式下假俭草的草坪高度显著高于覆土碾压建植方式下的（P〈0．05），但在前两种建植方式之间草坪高度不存在显著性差异；在3种方式之间，假俭草的地上生物量、草茎长度、分蘖数以及后期的覆盖度均没有显著差异，但草茎扦插方式下的前期覆盖度显著大于另外2种方式下的。最后指出撒茎覆土碾压是一种适于大面积推广应用的假俭苹草坪建植方式。...

Summary:采用3种草茎建植方式进行了野生假俭草无性繁殖的对比试验研究。结果表明：开沟植茎、草茎扦插两种建植方式下假俭草的草坪高度显著高于覆土碾压建植方式下的（P〈0．05），但在前两种建植方式之间草坪高度不存在显著性差异；在3种方式之间，假俭草的地上生物量、草茎长度、分蘖数以及后期的覆盖度均没有显著差异，但草茎扦插方式下的前期覆盖度显著大于另外2种方式下的。最后指出撒茎覆土碾压是一种适于大面积推广应用的假俭苹草坪建植方式。
Bibliography:The comparative study on three modes of stolon asexual reproduction [ planting stolon in ditch （PSD） , stolon cut- tage （ SC）, and covering the broadcasted stolons with soil and then pressing them （CBSSP） ] for wild Eremochloa ophiuroides was conducted. The results showed that the lawn height of Eremochloa ophiuroides under the modes of PSI） and SC was significantly higher than that under the mode of CBSSP （P〈O.05） , but there was no significant difference in lawn height between the former two modes. There was no significant difference in aboveground biomass, stolon length, number of tillers, and late-stage cover de- gree of Eremochloa ophiuroides among three modes, but the early-stage cover degree under the mode of SC was significantly higher than that under the other two modes. Finally, it was pointed out that CBSSP was a suitable mode for the large-area lawn establish- ment of Eremochloa ophiuroides in levees.
