油松是渭北高原比较优良的造林树种之一,但在这一地区,气候干燥,降雨量少,地下水位也低,油松育苗不易成功,造林成活率很低。这个问题,多年来一直没有很好解决。因此,我们从1974年开始,摸索、调查各种育苗方式方法——旱地育苗、容器育苗及塑料大棚容器育苗的经验,现加以整理,供作参考。一、旱地育苗多年来,我们在渭北高原淳化县、合阳县,陕北的安塞县以及蒲城县张家山等许多
Pinus tabulaeformis is one of the better afforestation species in the Weibei Plateau. However, in this area, the climate is dry, rainfall is low, the groundwater level is low, the pine seedling is not easy to succeed and the afforestation survival rate is very low. This problem has not been solved well for many years. Therefore, starting from 1974, we have explored and investigated various ways and means of raising seedlings - the experience of raising seedlings in nurseries, raising seedlings in containers and raising containers in plastic sheds is now being compiled for reference. First, the dry land nursery For many years, we in the Weibei Plateau Chunhua County, Heyang County, Ansai County in northern Shaanxi and Pucheng County, Zhang Jiashan and many other
