摘　　要：通过田间试验，研究合理使用液体复合肥套餐（A，B，C）对松嫩平原高产水稻产量、品质和经济效益的影响。选择3个典型种植户，综合比较常规肥料施肥和液体肥料施肥对水稻的影响。结果表明，与常规施肥比较，液体复合肥处理明显提高结实粒数，增产6．08％～18．35％，增产效果显著；液体肥料处理产出投人比分别达2．55、2．72和2．52，较常规肥料处理提高18．87％、9．85％和4．24％，净收益分别较常规施肥处理提高34．78％、16．04％和9．11％，显著提高农民经济效益；液体肥料在水稻上的应用还可减少施肥用工，用工成本可降低795～930元／hm^2。液体肥料通过合理的施肥方式施用，能够提高水稻的产量、品质、经济效益以及节省人工，在水稻上的应用是可行的。To investigate the effects of rational use of liquid compound fertilizer package （ A, B, C ） on yield, quality and economic efficiency of high-yielding rice in the Songnen Plain, this study selected three typical rice growers to comprehensively compare the effects of conventional fertilizer and liquid fertilizer on rice by field experiment. The results showed that compared with the conventional fertilization, the application of liquid compound fertilizer significantly increased the grain number and thd yield increased by 6.08%-18.35%. The output- input ratio of liquid fertilizer treatment was up to 2.55, 2.72 and 2.52, respectively, which increased by 18.87%, 9.85% and 4.24% than that of conventional fertilizer treatment. And the net income increased by 34.78%, 16.04% and 9.11% respectively, which significantly improved the farmers＇ economic benefit. The application of liquid fertilizer in rice could also reduce the fertilization labor, and the costs reduced by 795-930 Yuan/hm^2. The result indicated that the rational use of liquid compound fertilizer could increase the yield, quality of rice and economic benefits of farmers and save labor.
