摘要
通过对山东滕南煤田地区的土壤、煤矸石及部分农作物的灰份进行化学分析,从理论上探讨了其促进植物增产的机理;并认为该煤田3煤层的矸石含有与该地区土壤类似的化学组成,但其所含植物生长需要的主要元素普遍高于土壤中的含量,即煤矸石中含有较丰富的植物生长所需的矿物肥料。
The mechanism promoting the production of plants is discussed theoretically in this topic by analysising the soil, the gangues and a part of crops' ash chemically in Tengnan coal field, Shandong province. The gangues in the NO. 3 coal seam of this coal field have similar chemical composition with local soil. Further more, the results indicate that the principal elements containing in the gangues which the plants' growth needs are more than in the soil generally. There are rich mineral fertilizers in the gangue which the plants' growth needs.
