摘 要：該研究以創(chuàng)建高強度種植與地力提升共濟的理論為主攻目標，以我國糧食主產(chǎn)區(qū)分布最廣泛的東北黑土、黃淮海潮土、南方水稻土和紅壤為主要研究對象，力圖通過揭示限制地力提高的關(guān)鍵過程和因素，尋找有效調(diào)控途徑；通過中低產(chǎn)田土壤障礙因子消減和次生化過程阻控，恢復中低產(chǎn)田地力；通過有機物轉(zhuǎn)化過程及其驅(qū)動因子的調(diào)控，增加農(nóng)田土壤的有機質(zhì)積累；通過土壤物理化學性狀的改善，提高農(nóng)田土壤水分養(yǎng)分源匯容量和緩沖能力；通過關(guān)鍵生物過程和生態(tài)功能的促進，挖掘農(nóng)田地力提升的生物學潛力。最終闡明農(nóng)田集約化生產(chǎn)與地力培育共濟的原理和途徑；建立高強度種植農(nóng)田地力提升的理論體系；提出我國糧食主產(chǎn)區(qū)農(nóng)田地力定向培育的對策和建議。為國家1 000億斤增糧計劃的實現(xiàn)和未來糧食的持續(xù)生產(chǎn)做出重要貢獻。提升我國在農(nóng)田持續(xù)生產(chǎn)力研究方面的理論水平和解決實際問題的能力，引領(lǐng)國際農(nóng)田持續(xù)生產(chǎn)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
