落叶松凋落物对白菜与水曲柳种子萌发的影响

Effects of Larch Litter Solution on the Germination of Chinese Cabbage Seeds and Fraxnus mandshurica Seeds

将落叶松未分解和半分解叶水浸液稀释成1:10、1:30、1:50和1:100的处理液,用水曲柳和白菜种子做发芽实验。落叶松半分解水浸液对白菜种子的发芽有明显的促进作用,在高浓度时(1:10)这种促进作用经方差分析及其显著,但随着水浸液浓度的降低,促进作用减弱;而对水曲柳种子发芽的促进作用更为明显,即使是浓度为1:100时,也有促进作用。

Un- decomposed leaves and half- decomposed leaves of larch litter are soaked, which solution are diluted into 1 ： 10, 1 ： 30, 1 ： 50 and 1 ： 100. Using these solution to study the germination situation of Chinese cabbage seeds and Fraxnus mandshurica seeds. The result shows that the solution of half- decomposed leaves bud the gcrmination of Chinese cabbage seeds obviously and the stimulate is obvious significantly at high concentration （ 1 ： 10） by variance analyzing, but declining with the concentration failing. It is more obvious for the germination of Fraxnus mandshurica seeds, even at the concentration （1：100） also stimulate its growth.
