摘要/Abstract

摘要： 为在长江三角洲地区发展麦/玉米-稻新三熟种植制度,通过大量的田间试验和生产调查,对该熟制高产稳产的生态学原理进行了系统分析结果表明.春玉米在该地生态适应性较好,麦玉米套作中的作物种间关系以互补为主,三熟制资源利用率提高20%以上,能改善土壤物理性状和农田生态环境,并有内部有机物质投入保障,以及三熟制耐连作是其高产稳产的根本所在.

Abstract: In order to develop the wheat-corn-rice triple cropping system in Yangtze River delta region,the ecological principles for high and stable yield of this cropping system were systematically analyzed, based on field experiments and investigations. It was found that the local weather andsoil conditions were suitable to the growth of spring corn, the interspecific relationship inwheat-corn intercropping was mainly mutually beneficial, the agricultural resource in triplecropping system could be more effectively utilized by 20%, the soil phpeical properties and fieldecoogical environment could be improved, and soil fertility could be maintained by returnmgcorn straw into soil and the triple cropping system was tolerant to successive cropping. All ofthese consist of the basis of high and stable vield.
