摘要:
为了实现水稻超高产生产目标，采用小区对比法研究了不同肥密水平对不同穗型寒地水稻产量的影响，并分析其高产结构。结果表明：加大施肥量，进一步稀植后，与理论产量相比，穗重型品种松粳9号的实际产量仍有提高空间。中间型品种松粳5号和穗数型品种松粳3号的实际产量在3个密度下都有提高空间。松粳9号穗粒数随施肥量增加穗粒数增加幅度较大，说明靠穗重增加而增产；松粳5号和松粳3号穗粒数增加幅度较小，是靠增加穗数而增产。穗重型品种适宜密度20穴?m-2，中间型和穗数型品种适宜密度均为23穴?m-2。
Abstract:
In order to achieve super high yield rice production,the effect of different fertilizers and densities on rice yield of different panicle types rice was studied by using plot method.The results showed that with the increasing of the amount of fertilizer,spaced planting,compared with the theoretical yield,the actual yield of Songjing 9 had room for improvement.The actual yield of Songjing 5 and Songjing 3 had improved in the three densities.Songjing 9 panicle with fertilization increased grain number per panicle increased greatly,increasing yield by the increasing panicle weight ; grains per panicle of Songjing 5 and Songjing 3 increased to a lesser extent,increasing yield by increasing the panicle number per plant.suitable density of heavy panicle type rice variety was 20 points?m-2,suitable density of intermediate type and panicle weight type varieties was 23 points ?m-2.
