在小麦秸秆全量还田条件下，对氮肥不同运筹方式对水稻产量及其构成因素的影响进行了试验。研究结果表明，在水稻全生育期施氮总量不变的情况下，在一定范围内适当增加分蘖肥的比重，有利于促进水稻前期分蘖和干物质积累量的增加，进而增加单位面积有效穗数，提高单产。

Experiment was carried on the influence of wheat straw returning and different application methods of nitrogen fertilizer on rice yield. The results showed that the promotion of early tillering and dry matter accumulation were increased when total nitrogen unchanged, the proportion of tillering fertilizer appropriately increased in the whole growth period of rice, thereby the effective panicles and yield increased.
