简要介绍黑龙江省北兴农场耕地地力评价技术流程。以农场地块为单位全面调查北兴农场的耕地基础生产能力、土壤肥力状况、耕地利用状况,并作出综合评价,对耕地地力进行评价分级,对评价结果进行验证,针对评价结果提出耕地质量保护与建设的合理化建议,为促进测土配方施肥、农业可持续发展提供科学依据。
This paper describes the technology farmland productivity evaluation process in Beixing farm of Heilongjiang Province and investigation land-based production, soil fertility, land utilization, and make a comprehensive evaluation as Beixing block farm for unit. Evaluation of farmland productivity grading, to verify the evaluation results, evaluation results for the proposed construction of land quality protection and rationalization proposals in order to promote soil testing and fertilizer, and to provide a scientific basis for sustainable agricultural development.
