一、引言林木種子利用沙藏層積處理,在種子採集後經較長的時間給以濕度和低温,可以加速其休眠期的完成,促進其內部物質的轉化。催芽對於休眠期較長的種子可以使其發芽迅速整齊;對於發芽比較容易的,如加以催芽也可能促其吸收水分而加速發芽。 I. INTRODUCTION Forest trees are stratified by sedimentation of sand reservoirs. Humidity and low temperature can be applied to the seeds for a long time after the seeds are collected, which can accelerate the completion of their dormant period and promote the transformation of their internal materials. Germination for the dormant longer seeds can make it germinate rapidly tidy; for germination is relatively easy, such as to promote germination may also be prompted to absorb moisture and accelerate the germination.
