结果表明,各试验地种子发芽力的保持与在土壤中的深度关系密切,愈是深层的种子有发芽力的数量愈多.同一层次中,由6月至9月,有发芽力的种子愈来愈少.动物对种子的流动过程影响很大,试验类型中赤杨落叶松林内动物危害最重,埋藏较深的种子受害轻.试验地的种子,一年内发芽力损失严重,至9月20日测定,各试验地内有发芽力的种子已很少,一般只有1%～2%.
The results showed that the seed germination of each trial was closely related to the depth of the soil, and the deeper the seeds were, the more the number of germinating seeds was. At the same level, from June to September, To animals.The animals had a great influence on the flow of seeds, the animals in the experimental group had the most serious damage to the animals and the seeds buried deeper in the forest were harvested.The seeds in the experiment had a serious loss of germination power within one year, up to September On the 20th, the seeds with germinating power in each test area were few, usually only 1% ~ 2%.
