PROBLEM TO BE SOLVED: To provide a grain culm treatment scheme for thresher, comprising allowing sticking grains to drop while supporting threshed grain culms on an auxiliary receiving net and preventing ear tip delay or the like and allowing a threshed product to fall down at the terminal end of a receiving net via the auxiliary receiving net and a falling channel, thus smoothly removing sticking grains. SOLUTION: The grain culm treatment scheme comprises the following: In a threshing chamber 5, the threshed product is fed from the terminal end of the receiving net 4 via a dust feed port 16 into a treatment chamber 6 and threshed grain culms are discharged from the threshing chamber 5 via a fourth port 12. In the thresher 1 having the above mechanism, the terminal end of the receiving net 4 is provided with the auxiliary receiving net 4a with a filter hole larger than that of the receiving net 4, and the falling channel 20 via which the threshed product is allowed to fall is provided behind the dust feed port 16 and between the depth side of the auxiliary receiving net 4a and the wall 35 of the treatment chamber 6.
