摘　　要： 对种植在砂页岩母质发育的红壤上的银杏幼树施用石灰,不仅能提高土壤 pH 值,增加土壤有效养分含量,促进根系对养分的吸收,而且极显著地增加幼树高度、茎围和分枝数;同时也增加主枝叶片数和单叶干重,并推迟落叶时间。 A study of lime effect on Ginkgo biloba seedlings which were planted on red soil developed from arenaceous-shale mother rock was carried out.The results revealed that fertilized with lime not only increase soil pH and soil effective nutrient content,but also in- creased significantly the plant height,stem diameter and the number of main branch.Fertilized lime also increased the number of main branch leave,induced the leave dry weight increase and the deciduous period was postponed.
