承德县地处河北省东北部,属冀北山地地貌,气候属半干旱、半湿润的大陆性季风型气候,素有“十年九旱”之称。春季高温干旱,缺水已成为制约造林成活率的关键问题。如何提高造林成活率,承德县从现有立地条件和技术力量出发,围绕“保水”采取了几点关键技术。一、整地技术整地要以能够全部或基本拦截住地表径流,蓄水保墒为目的。整地方式和季节直接关系到土壤含水量的多少,影响着林木的成活率和生长。因此确定合理的整地方式和季节尤为重要。
Chengde County is located in the northeast of Hebei Province, Hebei Province is a mountainous terrain, climate is semi-arid, semi-humid continental monsoon climate, known as “10 years nine drought ” said. High temperature and drought in spring and lack of water have become the key problems restricting the survival rate of afforestation. How to improve the survival rate of afforestation, Chengde County, starting from the existing site conditions and technical strength, around the “water” to take a few key technologies. First, the preparation of land preparation technology to be able to land all or the basic surface runoff, water storage for the purpose. The way of site preparation and the season are directly related to the amount of soil water content, affecting the survival rate and growth of trees. Therefore, to determine a reasonable way of preparation and the season is particularly important.
