| 摘 要： | 目的]探索沿江稻区一季中稻超高产田块干物质积累的特征特性，主攻沿江稻区一季中稻超高产生产的瓶颈技术。方法]选用高产迟熟大穗型品种P88S／747进行强化栽培。结果]P88S／747最高苗量达到578．3万株／hm2，成穗率仅为39．40％。有2个灌浆速度高峰，强势高峰值在齐穗后10d左右，弱势高峰值在齐穗后38d左右。叶面积指数在分蘖盛期、抽穗期、蜡熟期分别为5．60、7．34、4．26，物质输出率与运转率分别为32．30％、30．73％。【结论]沿江稻区水稻超高产栽培技术的难点是稳定提高水稻的分蘖成穗率；超高产栽培必须选用大穗型迟熟品种，增加生育后期肥料施用比例。

| Abstract: | Objective] The study aimed to explore dry matter characters high yield and find the bottleneck technique of super-high production of one-season high yield rice in Yangtze River.Method] The high-yield,late-maturity and large spike variety P88S/747 was chosen to conduct intensified cultivation.Result] The high seedlings of P88S/747 reached 5 783 000/hm2,but the available spike rate was 39.40%.There were two filling peaks,strong filling peak appeared at 10 days after full heading stage,and sick filling peak... |
