[Objective] The paper was to summarize the research of system of rice intensification (SRI) technology in China. [Method] Through combination screening and factor analysis, the effect of appropriate system of rice intensification technology on yield formation of rice was studied. [Result] The technology had strong adaptability with good effort of yield increase in China, which improved air and light in fields, reduced the incidence of sheath blight, increased photosynthetic capacity of rice plants, increased root activity, enhanced nutrient transportation, increased the rate of paddy milled rice, reduced the chalky grain rate, and simultaneously saved input and labor, increased revenue. [Conclusion] System of rice intensification broke the China's traditional practice of larger planting density, and preliminarily demonstrated a larger yield potential.
