水稻(Oryza sativa L.)和油菜(Brassica campestris L.)轮作是中国南方地区常见的耕作制度,其优点在于能够提高农业土地利用率和增强土壤生产力,且能改变土壤生态环境。轮作栽培土壤生态环境的改变对作物生长具有益的作用,而土壤中微生物的变化是土壤生态环境改变的重要因素。因此,研究土壤微生物活性和多样性可为水稻和油菜轮作栽培对土壤质地的影响能够提供理论依据,对维持良好的土壤环境生态系统和农田可持续耕作具有重要的现实意义。以浏阳(短期试验:3 a)和安仁(长期试验:30 a)两地的稻-稻-油菜轮作土壤为研究对象,选取稻-稻连作土壤作为对照比较,分别于2015年7月、 10月和2016年4月取样测定...

Rice (Oryza sativa L.)-rape (Brassica campestris L.) intercropping is a routine farming practice in Southern China, and its advantage includes the increased land use efficiency and productivity as well as improving the soil environment. The improvement in the soil environment is beneficial to crop growth, which is mainly resulted from the changes in soil microbial communities during intercropping. For these reasons research on the soil microbial activity and biodiversity can provide important evidence for improving rice-rape intercropping farmi...
