Abstract:

The system of rice intensification (SRI) is 80 years of the 20th century by the Father Henri de Laulanie Madagascar proposed a new cultivation method, system of rice intensification in Madagascar's application was a better yield effect, in recent years, in Indonesia, China and other countries had carried out tests showed a larger initial yield potential, breaking the larger of Chinese traditional practice of planting density. Appropriate cultivation techniques through a combination of enhanced screening and factor analysis results showed that: the technology in China, strong adaptability and good yield, improved field of air and light, reducing the incidence of sheath blight, rice plants increased photosynthetic capacity, increasing root activity, enhancing nutrient transport, increase the rice milled rice, chalky rice rate reduction, and to save both labor and species, to increase revenue. As Chinese ecological conditions around the big difference, through Sichuan Province, Zhejiang Province and Jiangxi Province and more than 10 cities, which were studied around the improvement obtained for rice intensification technology.
