栽插密度和穗粒肥施用对水稻产量的影响因水稻品种类型和土壤水分胁迫程度而有较大差异：土壤水分充足（土水势为0），汕优63的产量为低密度（2万穴／亩）高于高密度（3万穴／亩），保花肥或粒肥的产量高于促花肥，盐粳2号栽插密度间的产量无显著差异，促花肥的产量显著高于保花肥或粒肥；在水分胁迫下（土水势为-35kPa和-50kPa），两供试材料均以高密度的产量高于低密度，促花肥的产量高于保花肥或粒肥。
The effects of transplanting density and ear-grain fertilizer application on rice yield were quite different due to the different types of rice and the degree of soil water stress. The soil moisture was sufficient (soil water potential was 0), and the yield of Shanyou 63 was low density (20,000 holes / Mu) was higher than the high density (30,000 acre / mu), the yield of fertilization or grain fertilizer was higher than that of the flowering fertilizer, the yield of Yanjing 2 was no significant difference, the yield of the flowering fertilizer was significantly higher than that of baohua fertilizer or granule fertilizer ; Under water stress (soil water potential of -35kPa and -50kPa), the yield of both tested materials was higher than that of low density and the yield of flowering fertilizer was higher than that of baohua fertilizer or granule fertilizer.
