我国黄土中微量元素的研究工作虽逐步开展,但多限于黄土中微量元素的一般含量和分布,而对黄土改造过程中元素的变化、存在状态及其与农业的关系研究较少。近年来,我们在学习大寨社员治山治水,改造黄土,建设大寨田的经验中,侧重对黄土和改造后耕作土中的几个与作物生长有关的微量元素(锌、铜、锰、钼、硼)进行了分析,本文就是在此基础上整理的结果。
Although the research work of trace elements in loess in our country has been carried out step by step, it is limited to the general content and distribution of trace elements in loess. However, there are few researches on the change, existing state and its relationship with agriculture in loess reform. In recent years, we have learned from the experiences of Dazhai members in managing mountains and water, rebuilding loess and building Dazhai. We have focused on the effects of several trace elements (zinc, copper, manganese, molybdenum , Boron) were analyzed, this article is based on the results of finishing.
