摘  要:
通过调查研究,提出了松辽平原玉米带粮食生产中存在的5方面问题。根据最近的一些研究结果,从土壤剖面构型、有效态养分平衡、有机无机复合体组成及土壤酸化趋势加剧等方面揭示了玉米带黑土肥力演化的特点,分析了驱动土壤肥力演化的原因。简要介绍了前期工作中提出的"三三(全)耕作制"对土壤肥力的培育效果,目的是为松辽平原玉米带土壤肥力退化的防治和定向培育提供理论和技术支撑。

摘  要:
In this paper,five aspects of problems about crop production in the Songliao plain corn belt through the investigation and study were discussed.According to the recent research results,characteristics of fertility evolution of black soil were revelated from soil profile configuration,available nutrient balance,composition of organo-mineral complexs and acidified tendency aggravating.The reasons to control soil fertility evolution were analyzed."Three-three-cultivation system" proposed in initial work and its effects of fertilizing soil were also introduced briefly.The goal was to provide theoretical and technical support for fertility degradation prevention and to direct fertilization of black soil in the corn belt of the Songliao Plain.
