The implementation of the new round of western development has brought a golden opportunity for the development of forestry. The enthusiasm around the country is very high. In order to lay a solid foundation for this tough battle, we have summarized a set of scientific and rational afforestation techniques. Now the technical points are summarized as follows: 1 improved afforestation technology Afforestation technology is the key to improve the survival rate of afforestation. My county site conditions can be divided into two types: semi-damp rocky mountain periphery of Liupanshan and central and western loess hilly region. Most belong to the central and western loess hilly region, undulating terrain, soil erosion is serious, combined with the existence of dry soil layer, to artificial afforestation bring difficulty. A few years ago the area afforestation save
