三江平原耕地微地貌差异对作物产量影响的系统分析

System Analysis of Farmland Micro-Topography Differences on Crop yield in San Jiang Plain

为了解决三江平原低湿耕地粮食生产经常受水害的问题,提出了垅平台栽培法。并对此法进行了全面的系统分析,证实这种微地貌的差异,在涝年对作物产量存在着明显的、多层次(地上、地下部)的正向影响,为推广实施这一农业技术措施提供了理论依据。

Broad and flat ridge cultivation method was proposed in order to solve the waterlogging problems in Sanjiang plain. The paper discussed the method systematically, and indicated that the differences of the micro-topography has eminent and multi-levels effects on crop yield in waterlogging year, which provides the theoritical basis for the extension and implementation of the practice.
