摘要
通过探究不同施肥量对寒地水稻产量及效益的影响,特做此项试验。结果表明:同一水稻品种在不同施肥条件下,穴穗数、穗粒数、结实率、千粒重和产量均存在明显的不同。其中,施氮量为94.0 kg/hm2的处理所获得的水稻产量最高,达到547.36 kg/667 m2。
The results showed that the panicles per hill, grains per panicle, kernel setting rate and 1000-grain weight varied obviously in one variety at different levels of fertilizer amounts. The highest yield of rice variety was 547.36 kg/667 m^2 when the nitrogen fertilizer amount was 94.0 kg/hm^2.
