种植密度对不同类型水稻品种株型、病害发生程度和产量性状的影响
|
摘要
以常规稻辽粳212和杂交稻辽优9906为试材,设置2.22、1.66和1.33万穴/667m~2 3个种植密度水平,分析种植密度对不同类型品种株型性状、病害发生程度和产量的影响,以确定最适宜的种植方式。结果表明:随着插秧密度增大,两个品种的发病率均增大;辽粳212在种植密度为2.22万穴/667m~2和1.33万穴/667m~2时产量均较高,而辽优9906同样在2.22万穴/667m~2种植密度下产量最高,因此,常规稻品种辽粳212可以适当稀植,而杂交稻辽优9906适当密植,同时加大病害防治,可确保产量优势充分发挥。
The conventional rice variety Liaojing 212 and hybrid rice variety Liaoyou 9906 were conducted under three planting density levels of 2.22×10~4, 1.66 ×10~4 and 1.33×10~4 hole/667 m~2 to analysize the effect of planting density on plant type, disease degree and yield traits and determine the most appropriate planting pattern. The results showed that with the increase of transplanting density, the disease incidence of both varieties increased. The highest yield of Liaojing 212 was under both planting density of 2.22×10~4 hole/667 m~2 and 1.33×10~4 hole/667 m~2, while that of Liaoyou 9906 was under planting density of 2.22×10~4 hole/667 m~2. Our results suggested the conventional rice variety Liaojing 212 and hybrid rice variety Liaoyou 9906 would be suitable for low and high planting density, respectively, while the disease prevention and control should be strengthened, in order to ensure the full expression of yield advantages.
