青檀是国家重点保护的珍贵树种,多为野生,是制宣纸的重要原料.为保护和扩大青檀资源,为石灰岩山区农民提供一条致富的门路,对青檀的人工栽培进行了研究.结果看出,青檀是一种适应性广的荒山绿化好树种;进行硬枝扦插繁育比较困难,以播种育苗为好,但须在播种前对坚硬的种子进行浸种处理;如为提高青檀树皮的产量,宜选用截干造林.
Pteroceltis is a precious tree species under the state’s key protection, mostly wild, and is an important raw material for making rice paper. In order to protect and expand the resources of P. erecta and provide a resource for farmers to get rich in limestone mountainous areas, the artificial cultivation of P. dahurica was studied. As a result, P. erecta is a good adaptable broad-leaved and afforested tree species. It is difficult to hard-cut and planted nursery stock, so it is better to seed nursery seedlings, but hard seeds should be soaked before sowing. Bark production, should use cut-off reforestation.
