摘　　要：土壤盐渍化、酸化是当前扁豆连作引起的主要问题之一,而扁豆-水稻轮作的种植方法能优化土壤环境。通过试验对比扁豆-水稻轮作、扁豆连作(CK1)和水稻连作(CK2)三种方法对土壤的影响,结果表明:与CK1相比,扁豆-水稻轮作情况下的电导率(EC)、主要阴离子、阳离子、盐渍化程度显著下降;土壤养分方面,扁豆-水稻轮作与CK1相比有所下降,各养分物质含量下降幅度在9.1%—27.1%,有助于水稻生长;土壤理化成分中总孔隙度扁豆-水稻轮作比CK2增加11%、土壤通气孔隙度比CK2增加9.7%。研究表明,扁豆-水稻轮作有利于土壤环境改良。Soil salinization,acidification is one of the major problems currently caused by lentil continuous cropping,while the soil environment can be optimized with the planting method lentil-rice crop rotation.This paper selected the lentil-rice crop rotation,lentil continuous cropping and rice continuous cropping,compared the effects on soil environment under these 3 methods.The results showed that compared CK1,the electrical conductivity（EC）,the main anionic,cationic,salinization degree were dropped significantly under lentil-rice crop rotation.Compared CK1,the soil nutrients dropped from 9.1%to 27.1%,which was good for the rice growth.On the soil physical and chemical composition,lentils-rice crop rotation increased 11%in total porosity and increased 9.7%in soil aeration porosity compared to lentils continuous cropping CK2.The study showed that lentils-rice crop rotation was conducive to improve soil environment.
