摘要
设置3种不同移栽密度(24万株/hm^(2)、30万株/hm^(2)、36万株/hm^(2)),探讨不同种植密度对‘宜香优2115’和‘泰优808’2个水稻品种产量及品质的影响。结果表明,适宜的种植密度(30万株/hm^(2))能有效提高2个品种的产量和部分品质指标,有效穗数显著增加,实粒数显著优于其他处理,脂肪酸含量显著降低,水稻品质得到改善。
In this study,three different transplanting densities(240000 plants/hm^(2),300000 plants/hm^(2),360000 plants/hm^(2))were set to explore the effects of planting density on the yield and quality of two rice varieties'Yixiangyou 2115'and'Taiyou 808'.The results showed that moderate planting density(300000 plants/hm^(2))could effectively improve the yield and some quality indexes of the two varieties.Specifically,under this density,the number of effective panicles increased significantly,the number of filled grains was significantly better than other treatments,and the fatty acid content decreased expressively,indicating that the rice quality was improved.
