摘要
增施化肥,打破千百年来“有机农业” 的封闭式循环,是由传统农业过渡到现代农业的必备条件.山西省粮食产量与化肥施用量呈同步增长的关系,相关系数为0.9486.进一步发展山西农业生产,必须重视化肥投入,走以无机促有机、无机有机相结合的道路.本文对一些流行观点提出了不同看法.
Increased application of chemical fertilizer , which has broken the closed cycle of organic agriculture for thousands of years , is a prerequisite for the transition of traditional agriculture to modern agriculture . Shanxi 's increased food production is positively and closely correlated with the increased application of chemical fertilizer , the correlation coefficient being 0.9486 . For further development of Shanxi's agricultural production , it is necessary to increase the input of fertilizer , to take the road of using inorganic farming to promote the organic farming, or to effect the integration of inorganic farming with organic farming. This paper presents some different views on current ideas about this issue .
