板栗嫁接成功与否,是直接影响其造林建园和栽植成活率的关键技术。因此,我们在实践中必须掌握正确的嫁接方法。现把板栗的嫁接技术作一简单介绍,供生产者参考。一、嫁接成活的主要因素。一是温度在18℃以上,最适温度为20℃左右:空气相对湿度80％以上,嫁接部位供氧要少。二是枝条粗壮、充实、新鲜芽健,嫁接部位平滑,位置恰当,枝龄年幼,这些相关因素要良好配合。三是要有熟练的嫁接技术和采取恰当的嫁 The successful grafting of chestnut is a key technology that directly affects the afforestation and planting and planting survival rate. Therefore, we must grasp the correct method of grafting in practice. Chestnut now grafting technology for a brief introduction for producers reference. First, the main factor of grafting survival. First, the temperature above 18 ℃, the optimum temperature is about 20 ℃: air relative humidity of 80% or more, less oxygen at the graft site. Second, the branches thick, full, fresh bud health, grafting site smooth, proper location, young age, these related factors should be well coordinated. The third is to have a good grafting technology and appropriate marriage
