摘要

以山桐子(Idesia polycarpa Maxim.)为研究对象,进行了极重短截、重短截、中短截、轻短截4种不同短截程度的修剪试验。结果表明,发枝数由少到多排序为极重短截、重短截、中短截、轻短截,4种处理间呈显著差异;新稍长度由长到短排序为极重短截、重短截、中短截、轻短截;新梢叶片数最多的是中短截处理,与其他3种处理均差异显著,极重短截、重短截和轻短截之间没有显著差异。
        Taking Idesia polycarpa Maxim. as research object, four kinds of pruning experiments were carried out including extremely heavy short section, heavy short section, medium short section and light short section. The results showed that the order of shoots number from less to more was extremely short, heavy short, medium short and light short, and there were significant differences among the four treatments. The order of new tip length from long to short was extremely heavy short section, heavy short section, medium short section and light short section. The largest number of new tip blades was the midium short section treatment, which is significantly different from the other three treatments. There was no significant difference among extremely heavy short section, heavy short section and light short section.
