Abstract: The results of experiments on different densities of riceseedling broadcasting and different norm of putting types in paddy fields show that the highest rice yield is gotten from the broadcasting density of 8 000 banches of rice seedlings, and the norm of putting 800-frys per 667m2 in the rice field. When putting norm over 400 frys per 667m2, the organic fertilizer produced by fish can have significant effect on rice yield. The fish output increases with the increasement of putting frys number. The best input-output ratio is 1∶3.21 when 8 000 bunches of seedlings and 800 frys per 667 m2 are put in the rice field. The rice yield with putting frys increases over 17% than the yield without frys putting.
