| 摘 要： | 采用野外分区试验的方法，研究了1年生赤松幼苗存活及影响因子。结果表明：人工整地措施能提高更新苗出苗率，使更新提前木质化，并对更新苗苗高有影响；坡位对更新苗保存率有显著影响；干旱和病害是影响更新苗存活的两个最主要因素。 |
| 关 键 词： | 赤松 存活 影响因子 一年生幼苗 出苗率 保存率 |

| Abstract: | Using the method of outdoors site experimentations, the survival and its affecting factors of yearlings were studied in the paper. The results show that the measure of artificial soil preparation can increase the seedling emergence rate and make them lignify early. It is also helpful to seedling height. Slope position has obvious effect on the survival rate of seedlings. The drought and disease are the main reasons which cause the death of yearlings. |
