南方红豆杉扦插繁殖技术研究——Ⅲ.叶面肥与透光度对扦插苗生长的影响

Studies on the cutting propagation of Taxus chinensis var.mairei.Ⅲ.Effects of foliage fertilizer and transparency on growth of the cut seedlings

  • 摘要: 试验研究叶面肥和透光度对南方红豆杉扦插苗生长的影响结果表明,喷施叶面肥对扦插苗 生长和叶绿素含量的影响呈正效应,而透光度的影响则呈负效应,且前者效应大于后者。 喷施叶面肥和未喷施叶面肥处理间扦插苗新梢长、苗鲜物质量和根鲜物质量及叶绿素含量 间差异均达显著水平;且喷施叶面肥处理40%与80%透光度间以上指标差异达显著水平, 40%与60%透光度间或60%与80%透光度间差异仅部分指标差异显著;而未喷施叶面肥处理 透光度对扦插苗叶绿素含量的影响仅部分处理间有明显差异,但不足以导致扦插苗生长量 的显著差异。

     

    Abstract: Effects of foliage fertilizer and transparency on the growth of the cutting of Taxus chinensis var.mairei were studied.The results show that the effects of foliage fertilizer on the growth and chlorophyll content of the cut seedlings are positive,but the effects of transparency on that are negative.In addition,the efficiency of foliage fertilizer is obvious stronger than that of transparency.Growth indicators of new log,plant fresh weight and root fresh weight in the cutting are accelerated distinctly by application of foliage fertilizer,and so is the content of chlorophyll a,chlorophyll b and total chlorophyll.Differences between application and in application of foliage fertilizer are significant.Only in the condition of application of foliage fertilizer,the differences of the growth indicators and chlorophyll content between transparencies of 40% and 80% are significant,the differences of part indicators between transparencies 40% and 60% or 60% and 80% are significant. Without the application of foliage fertilizer,a significant difference of chlorophyll content is observed in some transparency treatments,but no significant difference is observed in the growth indicators in all transparency treatments.
