摘要
本文就太原市土壤中有效态微量元素含量及分布进行了分析,在此基础上进行了微肥应用效应研究。结果表明,太原市有效态微量元素普遍较低,但多数地区含钼、铜较高。微肥应用效应与微量元素的含量分布相关,有较高的经济效益。
Distribution of micro—elcment and the effect of micro—fertilizers in different soil in Taiyuan were studied. The results shows the contents of micro—element is poor in Taiyuan.The contents of Zn,Cu,Mn,Fe is lack and ia rich in Cu,Mo in lager arca of Taiyuan.Crop yield was increased with application of fertilizers,with significant economic benefit.
