樟子松在亚热带地区育苗的可行性初探
|
摘要
为探讨北方寒带树种樟子松在亚热带地区进行育苗的可行性,于2017年4月在广西南宁进行了樟子松育苗试验,并进行种子发芽率、芽苗移植成活率、苗高、地径生长性状的测定。结果表明:在自然条件下,使用40℃温水浸种至自然冷却,并继续浸种至24 h后播种到发芽床,樟子松种子14 d发芽率达45%;采用轻基质无纺布容器育苗,以苗龄12个月计,樟子松芽苗移植成活率达67%,苗平均地径达0.5 cm,平均苗高达13 cm。
In order to discuss the feasibility of breeding the northern frigid tree species P.sylvestris in the subtropical area, seedling test had been performed in a nursery in Nanning, Guangxi on April 2017. Some indicators were tested about the seed germination rate, survival rate, seedling height and diameter growth. The results showed that the P.sylvestris seed were soaked in the 40 ℃ warm water until cooling naturally, continued to soak until 24 hours and sowed on the germination bed at the last. The P.sylvestris germination rate was up to 45% under the natural condition;using light matrix non-woven cup container to cultivate seedlings, the P.sylvestris seedling transplanting survival rate was 67%, the seedling average diameter was 0.5 cm, average height was up to 13 cm at 12 months.
