Abstract: Agricultural powerhouse is the root of a strong socialist modernization country. Contradiction analysis is the basic method of understanding things. The main contradiction stipulates or influences the other contradictions, so we should first analyze the main contradiction in the systems of the agricultural powerhouse in co-tense. On this basis, we should further study the major and minor aspects of the main contradiction in order to find the right way to solve the contradiction. For this reason, we need to analyze the positive and negative self-denial of the main contradictions in the systems of the agricultural powerhouse through the epochal state. The internal logic of a agricultural powerhouse is a reflection of the contradictory relations that govern the whole process. On the basis of the analysis of the internal logic of a agricultural powerhouse in co-tense and epochal state, the characteristics of the internal logic of a agricultural powerhouse are analyzed in a panoramic perspective. The relevant analysis of the intrinsic logic provides the theoretical basis for analyzing the practical principles of a agricultural powerhouse under the co-scenario perspective, and therefore the principles of grasping the main aspect of the main contradiction, the principle of negation of negation, the principle of organic combination of top-level design and practical exploration, and the principle of dynamic adjustment should be followed in the implementation of a agricultural powerhouse.
