摘要
分株是苎麻的一个重要生长特性,分株数是苎麻产量构成因素之一。为了解不同品种苎麻分株力的差异,以及分株数对农艺性状指标的影响,研究以26个苎麻品种为材料,对不同品种苎麻分株力的大小及其与农艺性状指标的相关性展开研究。结果表明:苎麻分株数的最大值出现在封行期;不同品种苎麻分株能力存在显著差异,根据分株数的大小比较,ZM-5的年总分株数最高,为30.78株/蔸,ZM-19的年总分株数最少,为16.89株/蔸;分株数与产量呈显著正相关关系,相关系数为0.383,与株高、茎粗呈极显著负相关关系,相关系数分别为-0.545、-0.603,与皮厚、有效株率呈显著负相关关系,相关系数分别为-0.410、-0447。试验结果为苎麻品种的科学利用及苎麻高产栽培技术提供理论依据。
The number of branches is an important constituent factor of ramie high-yield population structure. In order to understand the difference of ramets ability of ramie varieties and the effect of ramets number on agronomic traits, 26 ramie varieties were used to analyze the ramet ability and its correlation with agronomic traits by multiple comparison and correlation analysis in this study. The results showed that the maximum ramet number appeared in the closing period of ramie. According to the number of ramets, ZM-5 had the highest total number of ramets per year, which was 30.78 per plant, while Zm-19 had the fewest number of ramets per year, which was 16.89 per plant. There was a significant positive correlation between ramet number and yield, and the correlation coefficient was 0.383. The number of ramets had a very significant negative correlation with plant height and stem thickness, and the correlation coefficients were-0.545 and-0.603 respectively. The number of ramets had a significant negative correlation with skin thickness and effective plant rate, and the correlations were-0.410 and-0447, respectively. The experimental results provided theoretical basis for scientific utilization of ramie varieties and high-yield ramie cultivation techniques.
