为充分利用秋冬季秦岭红豆杉修剪的枝条,提高育苗成效,在汉中市进行了遮阴、增湿、除草等不同处理对冬季长枝扦插育苗成活率和育苗成效的试验,得出最优技术措施为采用春季每天喷雾1-3次、夏季3-5次、每次1 min;采用75%-85%遮光率遮光;5、7月各人工剪除高于插条杂草1次。

In order to make full use of pruned branches of Taxus chinensis in autumn and winter and improve the effectiveness of seedling cultivation,experiments were carried out in Hanzhong City with different treatments such as shade,humidification and weeding during long-branch cuttings in winter.The results showed that the best technical measures were spraying 1~3 times a day in spring,3~5 times a day in summer and 1 minute each time in winter,the shading rate of 75%~85%.,and weeding twice in May and July respectively.
