张佳宝　刘建立

摘 要：该研究以创建高强度种植与地力提升共济的理论为主攻目标，以我国粮食主产区分布最广泛的东北黑土、黄淮海潮土、南方水稻土和红壤为主要研究对象，力图通过揭示限制地力提高的关键过程和因素，寻找有效调控途径；通过中低产田土壤障碍因子消减和次生化过程阻控，恢复中低产田地力；通过有机物转化过程及其驱动因子的调控，增加农田土壤的有机质积累；通过土壤物理化学性状的改善，提高农田土壤水分养分源汇容量和缓冲能力；通过关键生物过程和生态功能的促进，挖掘农田地力提升的生物学潜力。最终阐明农田集约化生产与地力培育共济的原理和途径；建立高强度种植农田地力提升的理论体系；提出我国粮食主产区农田地力定向培育的对策和建议。为国家1 000亿斤增粮计划的实现和未来粮食的持续生产做出重要贡献。提升我国在农田持续生产力研究方面的理论水平和解决实际问题的能力，引领国际农田持续生产力研究方向。

Abstract：The project to create a high intensity and soil fertility improvement's theory of planting as the main target， the northeast black soil， the most widely distributed in the main grain producing areas in China， the South Huang Huai tide soil paddy soil and red soil as the main research object， tries to reveal the key processes and factors limiting productivity improvement， seeking the effective control method； the factor of soil obstacle of medium and low yield land cut and biochemical process control in low yielding fields， restoring force； by the transformation of organic matter and its regulation of the driving factors， and increase the organic matter of soil accumulation； the soil physical and chemical properties were improved， improve soil water and nutrient source sink capacity and buffering capacity； through the promotion of key biological processes and ecological function the biological potential， mining soil fertility improvement. Clarifying the farmland intensive production and fertility cultivation principle and way of Freemasonry； establishment of the theoretical system of high intensity cropping soil fertility improvement； put forward China's major grain producing areas of farmland productivity Oriented Cultivation Countermeasures and suggestions. To make an important contribution to sustainable production for the country 100000000000 catties of grain increasing implementation and future food. Enhance our theoretical level of farmland productivity research and the ability to solve practical problems， the leading international farmland productivity research direction.

Key Words：China food production bases；Soil productivity；Soil fertility cultivation；Principle and strategy
