摘要
在大田栽培条件下,研究了频繁刈割对中苎1号、湘苎3号、多倍体1号和湘苎7号分株、生物量及败蔸的影响。结果表明,随着刈割次数的增加,湘苎3号、中苎1号和多倍体1号分株数先增加后降低,湘苎7号分株数上下波动,4个苎麻品种的生物量呈下降趋势,且频繁刈割引起苎麻败蔸。在频繁刈割下,苎麻败蔸率为中苎1号>多倍体1号>湘苎3号>湘苎7号。
The objective of the present study was to investigate the influence of dipping on ramet,bi- omass and root - rotten of Zhongzhu - 1 ,Xiangzhu - 3, Tri - 1 and Xiangzhu - 7. A field trial was conduc- ted with a single - factor randomized block design. The results showed that the mmet number of Zhongzhu -1 ,Xiangzhu -3 and Tri -1 increased firstly and then decreased with the increase of cutting times,but Xiangzhu -7 changed up and down. With the increase of cutting times the biomass of 4 ramie cultivars re- dueed and root- rotten caused. Under were Zhongzhu- 1 〉 Tri- 1 〉 Xiangzhu - 3 〉 Xiangzhu - 7. root- rotten rates of 4 ramie euhivars
