Abstract: In order to evaluate the optimum transplanting period of high-quality rice, with the rationality of the change in transplanting period for improving the quality of high-quality rice to be discussed, the application basis of high-quality rice cultivation technology to be enriched, and the cultivation techniques of high-quality rice to be improved, by making the current transplanting period in Tianjin advanced or delayed, the correlation between the accumulative temperature and some measuring items, including the yield, yield components, the palatability quality, gelatinization characteristics and sense test were investigated. During transplanting to the spike stage, ‘Jinchuan NO.1’, ‘Jinyuan E28’ and ‘Jinyuan 45’ varieties were used. This experiment is aimed at obtaining the theoretical foundation and data support for high-quality rice cultivation techniques in Tianjin area. The results showed that there was a significant negative correlation between the comprehensive evaluation value of the sense test and the transplanted(P≤0.001), and the postponement of transplanting period decreased yield, but the quality of the quality rice was correspondingly improved. In order to obtain a higher yield and high-quality rice varieties, it is helpful to improve the quality of rice with the proper postponement of transplanting period.
