檫树是林业生产中的一个优良树种,具有生长快、材质好、适应性广的特点。新昌县栽培檫树已有一百多年历史,年收种子二万余斤,最近县府将檫树定为县树。由于檫树种子成熟期较长,当年采收的种子处于休眠状态,即使到第二年播种时,仍有相当一部分不会发芽,一般的场圃发芽率平均不到50%。同时由于檫树生态和形态上的特性,苗木起接砧嫁也要比树种更为困难。新昌县林科所为加速檫树造林和良种繁育,对檫树种子的隔年储藏和苗木起砧嫁接,进行了近五年的研究试验,取得了较好效果。五月中
Sassafras tree is an excellent tree species in forestry production, with fast growth, good material, wide adaptability. Xinchang cultivated Sui tree has a history of more than 100 years, received more than 20,000 kilos of seeds, the county government recently Sui tree as the county tree. Due to the longer mature period of the tree seed, the seeds harvested in the current year are dormant. Even if the seeds are sown in the second year, a considerable part of them will not germinate, and the average field seed germination rate is less than 50% on average. At the same time, because of the ecological and morphological characteristics of poplar trees, it is more difficult for seedlings to pick up anvil than to plant trees. In order to speed up the afforestation and seed breeding of tree plantation, Linchang Branch of Xinchang County has carried out research and experiments for nearly five years and achieved good results.
