| 摘 要： | 对辽宁省主要土壤类型耕地有效态微量元素进行化验。结果表明，若按低于临界值上限统计，３８．９％的土壤缺锌，７３．４％的土壤缺硼，８０．４％的土壤缺钼。而有效锰含量丰富。本文还探讨了微量元素有效含量与土壤有机质和ｐＨ值之间的关系

| Abstract: | The experiment was carried out in various cultivated soils in Liaoning Province for the available trace elemnets.The results showed that 38.9% of soil lacked Zn,73.4% of soil lacked B,80.4% of soil lacked Mo.But the Mn content in soil was rich.This paper also approached the relations of available trace elements contents with organic matter and pH value in soil. |
