摘  要：
【目的】研究不同栽培密度与穴播苗数对常规籼稻产量的影响,探索出不同穗型品种的合理种植密度和每穴播种苗数以指导农民种植。【方法】采用大穗型常规籼稻材料N2和中穗型常规稻材料N4每667m~2不同栽培密度和穴播种苗数的比较试验。【结果】材料N2在种植密度为1.7万穴/667m~2时产量最高,单产达500.0kg/667m~2,在每穴播种3苗时产量最高,单产达557.6kg/667m~2;材料N4在种植密度2.0万穴/667m~2时产量最高,单产达433.2kg/667m~2,在每穴播种3苗时产量最高,单产达481.1kg/667m~2。【结论】大穗型常规籼稻的最佳栽培方式为种植密度1.7万穴/667m~2与穴播3苗;中穗型常规籼稻的最佳栽培方式为种植密度2.0万穴/667m~2与穴播3苗。

摘  要：
【Objective】In order to study on different planting density and bunch seedling number influence on the yield of conventional indica rice, explore the reasonable planting density and bunch seedling number for different rice varieties and guiding farmers to grow.【Method】Conducted contrast test of separate 667m~2 with different planting density and bunch seedling number through conventional indica variety large panicle type N2 and middle panicle N4;【Results】The test results show that, the variety N2 with the advantage of highest yield when planting density 17 thousand/667m~2 with separately 3 seedlings for bunch seedling number;the variety N4 with the advantage of highest yield when planting density 20 thousand bunch seedling number/667m~2 with separately 3 seedlings for bunch seedling number.【Conclusion】The best cultivation for large panicle type conventional indica variety is applying the method of planting density 17 thousand/667m~2 with with separately 3 seedlings for bunch seedling number; and middle panicle conventional indica variety is applying the method of planting density 20 thousand/667m~2 with with separately 3seedlings for bunch seedling number.
