Study on High Yield Integration Technique of Single Cropping Hybrid Rice in the Rice Areas along Yangtze River

Based on the demonstration results of the application of rice high yield integration technique,the technological research,identification and comparison assessment were carried out for the most likely achievable goals namely,single-season rice production potential and super high yield in the rice areas along Yangtze River,then,demonstrated the feasibility of super high yield technology with 1.200 0 ×104 kg/hm2 and realized the possibility of more than high limit output with 1.275 0 ×104 kg/hm2,finally,put forward a series of system technical measures,such as,rice seedling extracting,stems enhancement,single ear equilibrium and grain weight improvement,which could effectively continue,intensify and supplement the advantages of high-quality groups in the entire process of growth.
