叶面肥和透光度对细叶青蒌藤扦插苗生长和质量的影响

Effects of Foliage Fertilizer and Transparency on Growth and Quality of the Cuttings of Piper kadsura

采用双因素随机区组设计,研究了叶面肥和透光度对细叶青蒌藤扦插苗生长和质量影响。结果表明:叶面肥对细叶青蒌藤扦插苗的生长和质量存在着正效应,透光度对细叶青蒌藤扦插苗的生长和苗木质量有着负效应。叶面肥与透光度对细叶青蒌藤扦插苗生长量指标的新梢鲜质量、新梢长度、叶片数量、叶面积与地下根系鲜质量、主根数量有着极显著性影响;叶面肥因素作用高于透光度因素;叶面肥与透光度双因素在细叶青蒌藤扦插苗的梢鲜质量、叶片数量、叶面积性状方面存在显著性或极显著性的交互作用。

Effects of foliage fertilizer & transparency on growth & quality of the cuttings of Piper kadsura were studied by means of two-factor randomized block design.Result shows that:effects of foliage fertilizer on the growth and seedling quality are positive,but effects of transparency are negative.Foliage fertilizer & transparency have very significant impacts on seedling quality of new shoot length,fresh weight of new shoot,leaf number,leaf area and root fresh weight,main root number of growth indicators of foliage fertilizer have very significant effects. Effect is higher than transparency.Two-factor (foliage fertilizer & transparency)have a significant or very signifi-cant interaction on the fresh weight of new shoot,leaf number,leaf area of the cuttings of Piperkadsura.
