根据试验结果,对杉木实生苗、萌条扦插苗和苗梢扦插苗的生长过程和质量进行了分析。结果表明:扦插苗的年生长节律与实生苗基本一致,生长盛期为8—10月中旬。两类苗木的质量,除了平均高、冠根比和合格苗的百分率差异不显著外,其它各项指标,扦插苗均显著或极显著地优于实生苗。两种扦插苗之间,除一级侧枝长度和Ⅰ级苗百分率差异达显著和极显著水平外,其它各项指标都无差异。
According to the test results, the growth process and quality of Chinese fir seedlings, cuttings of sprouting sticks and cuttings of shoots were analyzed. The results showed that the annual growth rhythm of cutting seedlings was basically consistent with that of the seedlings, and the peak growth period was mid-October-October. In addition to the average high, the percentage of crown-root ratio and qualified seedlings was not significantly different, the other indexes, cutting seedlings were significantly or very significantly better than the seedlings. There was no significant difference between the two kinds of cutting seedlings except for the difference between the first-stage branch length and the first-grade seedling percentage.
