通过不同用量配方肥施肥处理的比较试验,为湖南省水稻配方肥“大配方、小调整”施肥模式的调整提供了依据.结果表明:施肥量直接影响水稻整个生育期的生长和形态建成,包括株高、分蘖数、叶绿素含量、干物质积累量、叶鞘淀粉相对含量,最终导致产量的差异.在所有配方肥处理中,大配方模式处理(T4)的产量最高,而农民习惯施肥处理(T3)下的产量却高于大配方处理,其主要原因是养分含量(特别是钾)相对较高.因此,在湖南省洞庭湖区域将大配方模式处理中的钾适当提高,具有较好的增产前景.

The comparative experiments with treatments of applying various amounts of formula fertilizer provide basis for optimizing mode of gross formula and minor adjustment for rice formula fertilizer in Hunan Province. The results showed that fertilizer amount directly affected growth and morphogenesis of rice during entire growth period, thereby causing the differences in yield. Among all of the formula fertilizer treatments, the yield of gross formula mode treatment （T4） was the highest, but the yield of treatment with conventional fertilizer mod...
