冬季采桩好还是春季采桩好,近几年来人们说法不一,笔者根据实践观察认为采桩最佳时令是冬末春初,此时正是野生树木经受过严寒的考验进入蓄积养分时期,具有较强的生命力;此时树桩挖出来以后,由于空气湿度大,其本身不致大量蒸发水份,给树桩成活造成了良好的自然条件。而冬季的树桩本身新陈代谢的功能极其脆弱,其抗寒性和耐旱能力较低,再经挖掘伤了主根已造成生命节律紊乱。稍微干、湿、冻就会破坏正常休眠。一旦寒潮袭击,无本之木、无土之桩就容易冻伤,重则不到春季就会死去,有的则到春季还不能发芽,直至夏季才艰难萌发。实践证明同一树种在冬季挖掘虽然作了防冻保暖的措施,但于中晚春所采树桩复苏萌芽要迟的多。 Good harvest in winter or spring pile is good, in recent years, people have different opinions, the author believes that the best seasonal practice is the end of the winter harvest of piles, this time is the test of wild trees to withstand the cold into the period of accumulation of nutrients, with Strong vitality; at this time stump dug out, due to the air humidity, the large amount of water itself does not evaporate, to the survival of the stump created a good natural condition. The stump itself in winter metabolism is extremely fragile, its cold resistance and drought tolerance is low, and then hurt by the main root injury has caused the rhythm disorders. A little dry, wet, frozen will destroy the normal sleep. Once the cold wave attack, no wood, soilless pile easily frostbite, less then the spring will die, while others still can not sprout in the spring, until the summer was difficult to germination. Practice has proved that the same species of trees in the winter excavation despite the antifreeze warmth measures, but in the mid-late spring stump recovery sprouting should be much later.
