摘　　要：[目的]了解平茬对巨菌草生长状况的影响。[方法]以平茬前作为试验对照,与平茬后作比较,研究平茬对巨菌草株高、分蘖数、地上部分生物量的影响。[结果]与未平茬相比,平茬处理后巨菌草的生长速度明显增加,株高、分蘖数和生物量高于平茬前。[结论]平茬处理提高了巨菌草的生长速度,增加了巨菌草的分蘖数量,提高了巨菌草的生物量,可为后续巨菌草平茬研究和技术推广提供科学依据与参考。[Objective]In order to understand the effect of flat stubble on the growth of Pennisetum giganteum in northern regions.[Method]The effects of flat stubble on plant height,tiller number and aboveground biomass of Pennisetum giganteum were studied by comparing the results before and after flat stubble.[Result]Compared with the non flat stubble,the growth rate of Pennisetum giganteum after the flat stubble treatment was significantly increased,plant height,tiller number and biomass of flat stubble was significantly higher than that of non flat stubble.[Conclusion]The flat stubble treatment improved the growth speed of Pennisetum giganteum,increased the number of tillers,increased the biomass,and provided reference for the follow-up research and technology promotion of Pennisetum giganteum.
