影响曼地亚红豆杉扦插成活率的因素分析

Analysis on factors influencing living-rate of Taxus media

通过对曼地亚红豆杉Taxusmedia不同直径不同长度的穗条、不同扦插时间及覆膜与否、不同扦插基质等因子进行对比试验,得出剪取长5～7cm的粗壮插穗在春冬季扦插成活率最佳,而在夏秋高温季节则发根速度最快,但成活率偏低。

The experiment was made in Ningbo City of Zhejiang Province. Using series comparison tests to compare cuttage living-rate of Taxus media with different diameters and length spikes, different cutting time and mediums, wire or without plastic-sheet-covered practice, then come to a conclusion that Taxus media had the best living-rate when using 5-7 cm length strong spike cuttage in spring and winter, while rooting speed of was the fastest in hot seasons(summer and autumn), but living-rate was lower.
