刺楸(Kalopanax soptemlobus Koidz)属五加科刺楸属的乔木树种,为我国及辽宁的珍稀树种,用途极为广泛,深受人们的喜爱。多年来,由于刺楸育苗难度大,人工造林很少,天然生长的刺楸本来就很少,又加上滥采致使不少地方刺楸已濒临绝迹。研究刺楸育苗和生长节律,对于发掘刺楸种质资源,填补和培育优良阔叶造林树种具有重要意义。多年来,我们在刺楸育苗方面进行了探索研讨,结果如下。 Kalopanax soptemlobus Koidz is a tree species of genus Kaluga, which is a rare tree species in China and Liaoning. It has a very wide range of uses and is deeply loved by people. Over the years, due to the difficulty of raising Catalpa bungei, artificial afforestation is very small, native Catalpa bungei has very little, but also with indiscriminate mining caused many places Catalpa bungei is on the verge of extinction. Studying seedling raising and growth rhythm of kelp are important for finding germplasm resources of kelp and filling and cultivating good broad-leaved tree species. Over the years, we conducted research in the area of ​​seedlings of Thijasma, the result is as follows.
