摘要
根据6年来的马尾松收脂量,结合生态因子、树体因子、采脂间隔期、采脂负荷等因素进行分析,结果表明:马尾松产脂量与温度、树高、胸径等呈显著或极显著的相关关系,生态因子中以气温对马尾松产脂量的影响最大,树体因子中以树龄的影响最大,降雨、土壤、地形等因子对采脂量也有影响,这些因子对马尾松产脂量的影响作用是综合的。
The relation between oleoresin output of pinus massoniana and factors such as temperature, tree, interval of tapping oleoresin, and burthen of tapping oleoresin is analyzed, the results indicate that the relation is direct correlation. Temperature is the main ecological factor that influences oleoresin output intensively, but rainfall, soil, and landform influence less, and the age of tree is the most influencing factor in tree factors. These factors synthetically influence the oleoresin output of pinus massoniana.
