云南松是我省主要造林树种之一,目前大部分是直播造林。采用这种方式造林,播后受天气、干旱、鸟、鼠和虫等影响,很难达到成活要求。为提高造林成活率,马龙县今年对近千亩的荒山实行了云南松容器育茁造林试验且获得了成功。现将云南松容器育苗的技术简介如下: 云南松育苗造林的主要问题是,幼苗易感染猝倒病、易受日灼和过早分生侧根等。侧根多,影响移栽成活率。利用容器育苗,只要把握播种、移栽的时间,掌握技术和预防为主的措施,就可以解决以上问题,成功地育出苗来。关键是:
Pinus yunnanensis is one of the main afforestation species in our province, most of which are direct seeding afforestation. In this way afforestation, after sowing by the weather, drought, birds, rats and insects and other effects, it is difficult to achieve survival requirements. To improve the survival rate of afforestation, Malong County this year, nearly acres of barren hills implemented Yunnan pine container afforestation afforestation experiment and was successful. The Yunnan pine container seedling technology briefings are as follows: Yunnan pine seedling afforestation of the main problems is that seedlings susceptible to damping off disease, susceptible to sunburn and premature rooting and so on. More lateral roots, affecting the survival rate of transplanting. Seedling containers, as long as the sowing, transplanting time, master the technical and preventive measures, we can solve the above problems, successfully breed. The key is:
