东北红豆杉是第三纪孑遗树种和国家Ⅰ级重点保护的野生濒危物种,由于受人为破坏、繁殖生物学、生态学因素影响出现资源濒危,东北红豆杉对大气湿度要求严格,多散生于红松阔叶混交林内,居第二层林冠,为了加强东北红豆杉珍稀濒危物种抢救性保护,人工繁育关键技术主要为:种子繁育采用混湿沙雪贮藏层积处理,育苗管理防止幼苗日灼,采用遮阴网进行遮荫,透光率15%～20%,小苗移栽要遮阴,防止地蝼蛄幼虫对幼苗根系危害,大苗造林,应选择阴坡或半阴坡或日照短的沟谷排水良好的地带,防止长时间水涝产生厌氧使苗木根系死亡。通过人工繁育扩大种群,实现东北红豆杉濒危物种解濒的目标,进而抢救性保护这一珍稀物种。
Taxus cuspidata is a kind of wild and endangered species protected by Tertiary relict species and national grade I. Due to the damage caused by artificial damage, reproductive biology and ecology, the resource of Taxus cuspidata is strict with the atmospheric humidity. In order to strengthen the rescue protection of the rare and endangered species of Taxus cuspidata, the key techniques of artificial reproduction are mainly as follows: seed breeding using mixed wet sand storage layering, seedling management to prevent the seedling day burning , The use of shading network for shade, light transmittance of 15% to 20%, transplanting seedlings to shade, to prevent ground caterpillar larvae seedling root damage, seedling afforestation, should choose the shady or semi-shady or short sunshine short valley Drainage zone to prevent prolonged waterlogging anaerobic seedlings dead roots. Expand the population through artificial breeding to achieve the goal of endangered species of Taxus cuspidata, thus saving the rare species.
