摘要
红皮云杉人工林，≥０℃时芽展开，≥５℃时高生长开始。树高年生长量４４．９６ｃｍ，生长最速期在６月中旬，日平均高生长量１．７８ｃｍ。红皮云杉高生长天数为６１ｄ，属短速型树种。树高生长与积温、降水、日照相关紧密。直径生长６月中旬开始，７月上旬进入速生期，直径平均日生长量为０．０１ｃｍ，８月中旬直径停止生长，直径生长天数为５６ｄ，胸高直径年生长量为０．５２６ｃｍ。
For Picea koraiensis plantation, the bud begin to expand when the temperature is above 0℃. Height growth hegins when temperature is higher than or equal to 5℃. The annual height growth is 44.96cm. Fast growing period is in the middle of June, and the average height growth of the day is 1.78cm. Picea koraiensis belong to short growth peroid species, and its growth period is 61 days. There are close relationship among height growth, temperature accumulation and radation.
