摘要:
为提高水稻产量、品质及氮肥利用率，以水稻品种绥粳18为试材，研究肥密互作对水稻产量及其构成因素的影响。结果表明：供试品种在差异施肥量，差异栽培密度这两种因素处理下，千粒重差异不显著，穴穗数、穗粒数、结实率存在极显著差异。供试品种在施N91.0 kg?hm-2、 P2O5 46.0 kg?hm-2、K2O 23 kg?hm-2（N∶P∶K=1.9∶1.0∶0.5）、栽培密度为30.3 cm×13.3 cm时，产量最高，达到9 536.7 kg?hm-2。
Abstract:
In order to improve the yield and quality of rice and the utilization rate of nitrogen fertilizer,taking rice variety Suijing 18 as experiment material,the effects of fertilizer-density interaction on yield and its composition of rice were studied.The results showed that there was no significant difference in 1 000-grain weight,and there were very significant differences in the number of spike,grain number and seed setting rate of the varieties treated with different fertilization and the difference cultivation density.When applied to fertilize N 91.0 kg?hm-2,P2O5 46.0 kg?hm-2,K2O 23 kg?hm-2，N∶P∶K = 1.9∶1.0∶0.5,the density of 30.3 cm×13.3 cm,yield of Suijing 18 reached the highest value of 9 536.7 kg?hm- 2.
