摘要
根据邵阳市5a来的稻田地力监测试验研究,基本摸清了主要种植制度玉米稻的土壤养分变化动态,并综合分析其变化原因。提出了保持土壤养分动态平衡的技术对策,即适度增施有机肥对玉米稻复种制、保持地力不衰、稳定粮食产量具有重要作用。
According to the monitoring experiments of soil fertility of paddy field in five past years in Shaoyang, the dynamic changes of soil nutrients with the main cropping system （maize-rice） were demonstrated, and the reasons of that were comprehensive analyzed. The technological countermeasures that keeping dynamic balance of soil nutrients was proposed, which was properly increasing input of organic fertilizers is important for maize-rice cropping system, keeping stead soil fertility and grain yields.
