94年冬和95年春我们搞了毛白杨栽植对比。结果冬栽毛白杨成活率达到98%,而春栽毛白杨成活率只有86%。确实冬栽毛白杨成活率高、枝粗叶茂、生长快,冬栽虽气温低,而地温较高,栽上当年能长出新根,这样就克服了春栽气温高、地温低、先发芽、后生根、“回芽”、“假活”、三伏天死去的现象,同时也避免了与春忙农业生产争劳力争水源等矛盾。但有冬栽到翌
94 winter and 95 spring we engage in the cultivation of white poplar contrast. Results Winter survival white poplar survival rate of 98%, while spring white poplar survival rate of only 86%. Actually winter planting white poplar survival rate, thick branches and leafy, fast growth, although winter temperature is low, and the higher ground temperature, planted to grow new roots that year, so to overcome the spring planting temperature is high, low temperature, the first Germination, rooting, “back bud ”, “false live ”, dog days of the death of the phenomenon, but also to avoid busy with agricultural production in spring struggle for water and other contradictions. But winter planted to the next
