研究了稻麦两熟地区水稻抛秧栽培中的本田施氮量及配比， 结果表明， 随施 Ｎ 量的增加， 最高苗和有效穗增加， 在 Ｎ 肥配比上， 最高苗和有效穗是底肥足的高； 中 Ｎ 水平和前、中、后搭配施肥的 Ｒ Ｇ Ｒ、 Ｃ Ｇ Ｒ高， Ｎ Ａ Ｒ则在低 Ｎ 下较高； 一次枝梗数基本上不随施 Ｎ量和配比的变化而变化， 低 Ｎ 和中 Ｎ 下二次枝梗数无论在总的分化数还是在现存数、退化数上均基本一样，在高 Ｎ下二次枝梗数比低氮、中氮多分化３～４ 个， 同时也多退化２～３ 个，； 施肥量和配比对穗粒数和千粒重无显著影响；但从产量上看，本试验条件下抛秧栽培的施 Ｎ量应在１３５～１６５ｋｇ／ｈａ 之间， Ｎ肥分配对产量的影响差异不显著， 但从产量趋势看后期施肥是必要的， 且与施 Ｎ 水平有关。
The results showed that the highest seedling and effective panicle increased with the increase of N application rate. The highest seedling and effective panicle in N fertilizer ratio Which is high at the bottom of the foot; N R and R G R, C G R with medium fertilization before, during and after fertilization are high, N A R is higher at low N; the number of primary branches is basically not with N and the ratio The number of secondary branches in low N and medium N is basically the same in both the total number of exsertion and the number of extinction, ~ 4, but also degenerate 2 ~ 3 ,; fertilizer amount and proportion of spikelets and 1000-grain weight no significant effect; but from the yield point of view, the test conditions throwing transplanting cultivation N application rate should be 135 ~ 165kg / ha, the effect of N fertilizer allocation on yield was insignificant, but post-fertilization was necessary from the yield trend, which was related to the application of N fertilizer.
