Abstract: In order to improve the quality of rice cultivation and the palatability quality of food in the harvest period, this experiment adopted 3 varieties,‘Jinchuan No. 1’‘Jinyuan E28’and‘Jinyuan 45’respectively, and analyzed the effects of harvest period on rice yield and sense test the measured indicators including the yield, yield components, physicochemical properties, gelatinization characteristics of the crop, moisture content and palatability quality were studied to identify the best harvest period of high quality rice varieties. According to the condition of ensuring the moisture content of paddy more than 15%, the results showed that there was a significant positive correlation between the comprehensive evaluation value of the sense test and the period of harvest(P≤0.05); based on the effect of the harvest temperature in the transplanting period on the yield and taste of high quality rice, it is necessary to determine the optimum harvesting period on the basis of appropriate delay transplanting period, which can ensure the high yield and high quality of rice.

Key words: rice, cultivation, palatability quality, production, moisture, physicochemical properties
