摘要: 为提升水稻栽培技术,改进水稻收获期的食味品质,以‘津川1号’‘津原E28’和‘津原45’3个品种为试验材料,分析收获期对水稻产量和食味品尝试验的影响,同时进行了出穗至收获期积温和产量、产量构成要素、理化学特性、糊化特性、物化特性、水分及食味品质的相关性研究,旨在明确优质水稻品种最佳收获期。结果表明:在保证稻谷水分不低于15%条件下,收获期的食味品尝试验综合评价值与出穗至收获积温之间呈显著正相关(P≤0.05);适当延迟收获期,可提升水稻食味。根据并行试验移栽期对水稻产量及食味的影响,应在适当延迟移栽期的基础上,确定最佳收获时期,确保水稻的高产和优质。

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.
