| 摘 要： | 为提高日光温室香椿苗的质量和产量,采用二因素随机区组试验,研究了不同密度和施用钾肥对香椿苗植株高度、叶片数、主干粗度、成熟枝条长度等生物学指标的效应。结果表明:各处理间日光温室香椿苗的植株高度和叶片数无显著性差异,降低密度和施用钾肥可有效提高香椿苗的主干粗度和成熟枝条长度,其中以密度为50株/m~2且施用钾肥处理的主干粗度和成熟枝条长度最大,以密度为100株/m~2且施用钾肥处理的经济效益最好。

| Abstract: | Using the design of two factors randomized blocks experiment methods in order to improve the quality of Toona sinensis breeding and yields.This experiment was conducted to study at biological indicator's effects of plant seedling height,leaf number,trunk diameter,branch length of Toona sinensis under the conditions of different densities and the application of potash fertilizer.The results showed that the seedling plant height and leaf number in different treatment was no significant difference,lower densit... |
