摘要:: 为优化和推广寒地水稻侧深施肥技术，分析比较了寒地水稻不同比例控释尿素侧深施用效果。结果表明，基肥侧深施肥较常规施肥能够显著增加水稻有效穗数，进而提高产量和经济效益；处理SD1（控释尿素,80%N,侧深施）、SD2（控释尿素,60%N,常规尿素,20%N,侧深施）、SD3（控释尿素,40%N,常规尿素,40%N,侧深施）、SD4（控释尿素,20%N,常规尿素，60%N,侧深施）水稻单位面积有效穗数分别平均增加18.5，25.5，16.8和15.4个·m-2，产量分别平均增加325，672，522和218 kg·hm-2，增产率分别达4.2%、8.7%、6.7%和2.8%，其中处理SD2与处理FP(常规尿素，50%N作基肥,30%N作分蘖肥)差异达显著水平；经济效益分别平均增加848.05，1 792.45，1 566.85和978.85元·hm-2。采用侧深施基肥80%N（控释尿素氮与普通尿素氮比例1∶1～3∶1）,穗肥20%N，水稻产量效益最佳。

Abstract:: In order to optimize and promote the side-deep fertilization technology for cold-region rice, the effects of different proportions of controlled-release urea side-deep application on cold-region rice were analyzed and compared. The results showed that side-deep application of base fertilizer could significantly increased the number of effective panicles per unit area of rice compared with conventional fertilization. The average number of effective panicles per unit area of rice in treatment SD1 (80% controlled-release urea side-deep application), treatment SD2 (60% controlled-release urea combined with 20% urea side-deep application), treatment SD3 (40% controlled-release urea combined with 40% urea side-deep application), and treatment SD4 (20% controlled-release urea combined with 60% urea side-deep application) were increased by 18.5, 25.5, 16.8 and 15.4 panicles·m-2, respectively. The average yield of rice were increased by 325, 672, 522 and 218 kg·ha-1, respectively, with yield increases of 4.2%, 8.7%, 6.7% and 2.8%, respectively. Among them, the difference between treatment SD2 and treatment FP was significant. The average economic benefits were increased by 848.05, 1 792.45, 1 566.85 and 978.85 yuan·ha-1, respectively. The application of 80% nitrogen fertilizer as base fertilizer side-deep (the ratio of controlled-release urea to ordinary urea was 1∶1 to 3∶1) combined with 20% urea topdressing at the earing stage had the best yield and economic benefits for rice.
