我区实行造林以灌木为主的方针以来,提高了灌木的地位,各地都在大造灌木林,其中柠条造林数量最大,有些地方形成了‘柠条热’。这是好现象,但是存在一些技术性的问题需要引起注意。据我们了解,柠条在造林上有两个问题。一是有的单位为了提高其成活率,实行柠条植苗造林。实践证明,这不是提高其成活率的作法,而是提高造林成本的作法。在春旱的情况下,植苗造林不能解决抗旱问题。柠条造林方
Since the implementation of the principle of afforestation and shrub-domination in our district, the status of shrubs has been enhanced. Large shrubs have been built around the region. Among them, the largest number of afforestation is the species of Caragana korshinskii and the “Caragana sp.” Has been formed in some areas. This is a good sign, but there are some technical issues that need attention. According to our understanding, kaffir has two problems in afforestation. First, some units in order to improve their survival rate, the implementation of planting and planting Caragana korshinskii. Practice has proved that this is not a way to increase its survival rate, but to increase the cost of afforestation. In the case of spring drought, plantation and afforestation can not solve the drought problem. Caragana plantation
