为探明不同养分管理模式对水稻产量及氮肥利用率的影响,采用田间小区试验研究了不同养分管理模式下早稻产量及氮肥利用率的差异。结果表明,不同时期合理配施氮磷钾肥混施有机、无机肥能显著提高早稻产量,同时显著提高水稻氮肥利用率。

The effects of different nutrient management modes on yield of early rice and nitrogen use efficiency of in field-plot experiments were studied. The results showed that combined application of fertilization of nitrogenous fertilizer （N）, phosphate fertilizer（P） and potash fertilizer（K）, and mixed application of organic fertilizer and inorganic fertilizer in different stages could significantly increase the yiel...
