| 摘 要： | 根据苏北地区作物结构的系统分析，将该地区分为５种轮作类型区。通过不同耕法的产量效应与时间分异、土壤肥力时空变化特征的研究，论证了轮耕制的机理，提出了苏北农区轮耕制的一般原则与测土耕作的原理与方法。在单项技术效应与分区定位综合研究基础上，初步形成了苏北主体轮作方式的轮作轮耕轮培优化模式

| Abstract: | According to the analysis of crop compositions in north Jiangsu,the region was divided into five subregions interms of crop rotation types. The researches on the effects of different tillage methods on the crop yields,yield trends andchanges in the soil fertility revealed the mechanism of tillage rotation and furthermore,the principle and procedure of tillagerecommendation by soil test were put forward. In addition to the comprehensive location studies, we established main opti-mized patterns of integrated crop rotation,tillage and straw return to the soil in north Jiangsu. |
