营造速生丰产林是缓和森林资源危机的重要途径之一。本文就营造速生丰产林的技术谈点看法。一、立地条件要选择速生丰产林的立地条件,如杨树应选择肥力较高(有机质含量0.7—1.0％)、土层深厚疏松(0.6—1.0米以上的土层厚度)、地势平坦、地下水源比较充足、酸碱度中性或微酸性的土壤作为造林地。 Creating fast-growing and high-yielding forests is one of the important ways to ease the crisis of forest resources. This article talk about the technology to create fast-growing and high-yield forest. First, the site conditions to select fast growing forest site conditions, such as poplar should choose a higher fertility (organic matter content of 0.7-1.0%), deep and loose soil (0.6-1.0 meters above the thickness of the soil), flat topography, groundwater sources Adequate, pH neutral or slightly acidic soil as afforestation.
