1979年,我所对大连、营口,锦州、朝阳、丹东等五市的果园土壤进行了实地考察并采样分析。土壤有机质的变化范围大致在0.5～1.5％之间。需要说明的是,这次采样偏重于较好的果园,对低产园采得很少。全面地看,多数在1％以下,个别还有0.2～0.3％的。这说明我省果园土壤有机质含量是低的,并且每 In 1979, I conducted field surveys and sampled analyzes on orchards of the five cities of Dalian, Yingkou, Jinzhou, Chaoyang and Dandong. The range of soil organic matter is about 0.5 ~ 1.5%. It should be noted that, this sampling emphasis on better orchards, low-yielding garden mining very little. In a comprehensive view, the majority is below 1%, with some 0.2 to 0.3% each. This shows that our province orchard soil organic matter content is low, and each
