作物轮作时间影响土壤质量众所周知，作物轮作如棉花收获后复种小麦能改善土壤结构及其它物理特性，复种豆科作物能增加土壤氮素营养。过去曾作过多次短期试验（３年轮作制），但就棉花与禾谷类或豆科类作物的长期轮作（７年以上）的试验资料较少，为此，澳大利亚棉花中心...

Crop Rotation Time Affects Soil Quality It is well-known that crop rotation, such as cotton harvesting, can improve soil texture and other physical characteristics, and crop multiple cropping can increase soil nitrogen nutrition. There have been many short-term tests (three-year rotation) in the past, but there is less experimental data on long-term rotation (more than seven years) of cotton and cereals or leguminous crops, and for this purpose the Australian Cotton Center ...
