AbstractThroughthestudyofdiferentreturningamountsofrapegren manure，itwasfoundthatwen theretumingamountwas 22500kg/hm2 ，the rice yield was the highest. Compared with the treatment of 0kg/hm2 returning amount，the number of grains per panicle increased by 24.2 grains/panicle，an increase of 22.8% ，and the actual yield increased by 739.5kg/hm2 ，an increase of 8.4% . The yield wasincreased intheseason whentherape green manure wasreturned tothe field.Theresults showed that the treatmentof 22500kg/hm2 （20 couldefectivelyicasethontetoflableosphosndali-drolabletrogninesoilfteicarvestWnuing amount was 22 500 and 15000kg/hm2 ，the rice milling，cooking and eating quality improvement effect was the best. Therefore，considering the improvement of rice yield，soil improvement effect and ricequality improvement，the returning amount of 22500kg/hm2 is the optimum returning amount of rape green manure.
