摘要
黑龙江省耕地质量的状况不容乐观,耕地持续生产能力低,耕地生态环境恶化,限制黑龙江省耕地土壤生产能力的"低、费、污"问题已经逐步成为耕地土壤质量新一轮的核心问题。以"藏粮于地"的理念,替代"藏粮于库"的做法;加强耕地质量保护,加快实施"沃土工程";建立耕地质量保护机制,实施耕地质量保护工程。参6。
The envrionment of cropland in Heilongjiang province is deteriorating continuously, and the situation of cropland quality is a very serious problem at present. It can be described as ＂ low productivity, high cost and high pollution＂. This is the key problem appearing in recent years at the research of farmland quality, and it will limit the agricultural sustainability greatly.
