在研究分析中国现代种植环境中土壤微量元素循环的规律和缺乏现象的基础上,针对其不可持续性提出了选用低灰和低有害物质的粉煤灰作为土壤微量元素补充改良剂使用的理论观点,并通过选择用以大同煤为燃料的胜利油田发电厂排出的粉煤灰为研究对象,在龙口地区进行了大田种植玉米的试验研究.研究结果表明某些低灰的且有害元素含量少的煤所形成的粉煤灰,可以作为土壤微量元素补充的改良剂来大量使用并获得较好的土壤改良和农作物增产的效果.

This paper proposes the academic view of using low ash and less toxic coal fly ash as the soil trace element supplementary ameliorant, which is based on the analysis of circulation rules and loss of soil trace element in modern Chinese planting environment and the unsustainable phenomenon of soil trace element caused by modern planting modes. The corn planting field plot experiment has been conducted in Longkou with the selection of burnt Datong coal fly ashes discharged from the power plant of Shengli Oil Field. The result has demonstrated that ashes discharged from coal with low ash and less toxic substance, can be used vastly as soil trace element ameliorant,and it can maintain better soil ameliorant and increase the yields of crops.
