我校稻田复种轮作方式研究课题组,于1979年冬—1982年秋,在江西南昌地区进行稻田复种轮作方式研究第一轮作周期的试验,本文就其结果以及对复种轮作方式、换茬、复种方式的产量效益、经济效益、生态效益进行了分析讨论。表明复种轮作优于复种连作,如肥稻稻→麦稻豆→油稻稻复种轮作三年总产平均比肥稻稻连作增产8.44%,经济效益高11.95%。换茬优于连作,但以油稻稻要求最迫切。复种方式中,肥稻稻三增显著。文中还根据试验结果提出了在江西的应用意见。
In the winter of 1979 to the autumn of 1982, the research team of rice rotation cropping system conducted the first round of crop rotation experiment in paddy field in Nanchang, Jiangxi Province. In this paper, the results of this study and the results of multiple crop rotation, The yield, economic and ecological benefits were analyzed and discussed. The results showed that the multiple crop rotation was better than the multiple cropping. For example, the average output of three years of the combination of the paddy rice → wheat and the paddy rice increased 8.44% and the economic benefit was 11.95%. Cropping better than continuous cropping, but the most urgent requirements of oil rice. Among the multiple cropping methods, the increase of fattening rice is significant. According to the test results also put forward the application of the views of Jiangxi.
