| Abstract: |
| 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/hm2. 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. |
