土壤水分条件对红皮云杉种子的发芽、成活与生长影响很大，确定其种苗耐旱和耐湿的临界值，对提高红皮云杉种子的发芽率及苗木生长具有重要意义。本试验采用模拟试验方法，对土壤水分与红皮云杉种子发芽率及苗木生长的关系进行了研究。１ 试验方法将木制盆（盆口５０ｃｍ×３
Soil moisture conditions have a great influence on the sprouting, survival and growth of spruce seeds. To determine the critical value of drought and moisture tolerance of spruce seed is of great significance to improve the germination rate and seedling growth of spruce seeds. In this experiment, the relationship between soil moisture and seed germination rate and seedling growth of Picea koraiensis was studied by means of simulation test. 1 Test Method The wooden basin (basin 50cm × 3
