摘要
采用模拟养分循环开展长期定位试验的方法对黑土区不同养分循环结构农业经营制度进行了比较研究，结果表明，有机－无机相结合的农业制度包括传统农业与“石油农业”两者之长，是我国农业生产常久不衰、提高系统生产力和养分循环再利用的有效途径．
A comparative study on the agricultural managenent systems and their optimization in the black soil region of Northeast China wassconducted.The simulation m experiment results show that combining organic-inorganic gricultural management system has the common merits of traditional agriculture and ppetroleum one.It is a suitable management system for developing Chinese agriculture and improving system productivity and nutritional cycling structure.
