摘　　要：通过对超级杂交早稻新品种株两优819在不同自然与技术条件下种植的产量差异的分析比较,较系统地研究了自然与技术条件对水稻产量的影响。结果表明,自然生态条件对产量的影响大,是影响产量的主要因素;技术条件是影响水稻产量的重要因素。加强配套技术研究、集成与推广、普及对提高大面积水稻产量水平具有重要作用。The effects of natural and technical conditions on rice yield were studied systematically by comparing and analyzing the differences in yield of the new super hybrid rice variety Zhuliangyou 819 ureter different natural and technical conditions. The results showed that natural ecological conditions were the main factors to affect rice yield. At the same time,the technical conditions were also important factors to affect yield. So strengthening research,integration,promotion and popularization of the supporting techniques will play an important role in enhancing the yield level of large-scale rice.
