Innovation and Practice of High-Yield Rice Cultivation Technology in China

Rice is a staple grain crop in China and also the highest yielding one in grain crops. Using Chinese agricultural statistical data and the literature, this paper analyzed the successful experience of innovation and practice, problems and development trend in high-yield cultivation technology in rice, the characteristics of four periods of rice production in China, the contribution of supporting cultivation technology for variety to yield increase, and high-yield cultivation techniques developed in different periods. The characteristics of rice cultivation technology in world are briefly expounded. Supporting cultivation technology for dwarf varieties, hybrid rice, and super rice in the evolution of rice variety and rice industry development was reviewed. The current problems of high yielding cultivation of rice was analyzed. The development of high-yield rice cultivation technology was also discussed. Innovation of supporting cultivation technology based on the growth characteristics of new variety, rice cropping system, rice production models, and ecological environment exploits yield potential of variety and realizes the increase of yield and profit, promotes the development of the rice industry, and improves the environment and raises the efficiency of resource utilization.
