光量与球蚜发生关系的研究

1. In Shaoshing-Anling cutover area, due to great variations in climatic factors, on which a originally damp and humid natural forest was turned into a warm, sunny and dry younger forest after all the big trees are cut down. Among the smaller trees, the most important one is Pioea Koraiensis, next is Abies nephrolepis, Larix dahurics and Pinus koraiensis, With the changes in the forest tree species, age of trees, tree density and other climatic factors, the population density of several phototactic Adelgids...
