摘要
水旱轮作是具有中国特色的种植制度,在我国农业生产中占有十分重要的地位.本文以营养元素锰为例,针对水旱轮作中出现的土壤肥力及植物营养问题进行了论述,并提出了进一步研究的方向和相应的防治对策.
Rotation of paddy-upland crops, as a cropping system with Chinese characteristic, plays very im-portant role in China agricultural production. This article discusses soil fertility and plant nutrition problemscaused by rotation of paddy-upland crops. As an example, problems of Mn deficiency in wheat under condi-tion of such rotation are analyzed in detail. Meanwhile, the authors also point out next research direction andrelated prevention strategy.
