东北黑土区耕作措施对土壤水热效应的影响研究的开题报告 【摘要】 东北黑土区是我国重要的粮食籽粒和经济林带，是我国农业生产的重要农业区。然而，在农业生产过程中，由于过度耕作和土地的不合理利用，导致了黑土的退化和破坏，严重影响了土壤水热效应，造成了许多环境问题。 因此，本研究旨在探讨东北黑土区耕作措施对土壤水热效应的影响，并提出相应的改善措施，以保护黑土资源，提高农业生产效益。本研究将运用实验室分析和野外调查的方法来研究耕作措施与土壤水热效应之间的关系，研究内容包括：黑土缓冲带的建立、轮作制度的实施、施肥措施的优化等。 本研究的结果有助于深入了解黑土区农业生产过程中存在的问题，并提出可行的解决措施，对黑土资源的保护和农业生产的增产效益将具有重要的意义。 【关键词】 东北黑土区；耕作措施；土壤水热效应；改善措施 【Abstract】 Northeast black soil region, an important grain and economic forest belt in China, is a major agricultural region in China. However, due to over-cultivation and irrational land use in the process of agricultural production, the degradation and destruction of black soil have led to serious environmental problems, severely affecting the soil water and heat effect. Therefore, this study aims to explore the influence of cultivation measures on soil water and heat effect in Northeast black soil region, and put forward corresponding improvement measures to protect black soil resources and improve agricultural production efficiency. This study will use laboratory analysis and field investigation methods to study the relationship between cultivation measures and soil water and heat effect, including the establishment of a black soil buffer zone, the implementation of crop rotation system, the optimization of fertilization measures, etc. The results of this study will help to delve into the problems of agricultural production in black soil region and propose feasible solutions, which will be of great significance for the protection of black soil resources and the increase of agricultural production efficiency. 【Keywords】 Northeast black soil region; cultivation measures; soil water and heat effect; improvement measures
