我们于1974年从黑龙江省带岭林区调来红松(Pinus koraiensis sleb et Zucc)苗木,在巴林和南木两地的柞桦次生林内,进行引植驯化试验。该造林地超出红松自然分布区,气温较低,降雨量较少,春季经常出现干旱。经过13年的精心培植,红松成活与生长状况良好,取得了引植驯化的成功。一、引植后红松幼树生长状况针对红松的生物学习性,选择了土壤肥沃,排水良好,10度以上的东北和东南坡
In 1974, we picked up Pinus koraiensis sleb et Zucc seedlings from the Linglin area in Heilongjiang Province and carried out plantation and domestication experiments in secondary forests of oak in Bahrain and South Wood. The afforestation area beyond the natural distribution of Korean pine, the temperature is low, less rainfall, spring often dry. After 13 years of meticulous cultivation, Korean pine survival and growth in good condition, made the success of planting and acclimation. First, the growth of seedlings after the introduction of Korean pine tree for biological learning habits, select the soil fertile, well drained, 10 degrees above the northeast and southeast slope
