保护性耕作在不同气候区域研究现状

摘要

Different tillage managements can impact the soil water-heart-nutrient processes,long-term unreasonable tillage management can lead to yield reduction,loss of water and soil resources and environment pollution.Thus,studying effect of different tillage managements on crop yields,soil water,heat and nutrient dynamics,which can provide theoretical basis and technical support for developing the best management practice,improving the crop yields and soil situations,maintaining the healthy environment.In this article,the research progress and problems about the conservation tillage managements in different climate areas were reviewed.Some suggestions on the implementation of conservation tillage in the future were put forward.%不同耕作措施会影响作物产量和土壤水热及养分过程,长期不合理的耕作制度不但会降低作物的产量及品质,还会导致水土资源的流失和环境的污染.因此,研究长期不同耕作制度对土壤水热养分及作物生长和产量的影响,可为提高作物产量和土壤理化性状、降低环境风险、实现合理的区域农田管理措施提供理论依据和技术支持.阐述了国内外不同气候区域保护性耕作的研究进展以及存在的问题,并对今后保护性耕作的实施提出了几点建议.
