Abstract：The effects of four kinds of edible fungus residue fertilizer which included JZA ( pure edible fungus residue),JZB(edible fungus residue to cattle manure ratio was 0. 5),JZC(edible fungus residue to cattle manure ratio was 1) and JZD(edible fungus residue to cattle manure ratio was 2) and three ap-plication amounts(3 000 kg/ha(JZ1),6 000 kg/ha(JZ2),and 9 000 kg/ha(JZ3)) on wheat yield and yield components were studied with the treatment without edible fungus residue fertilizer as control ( CK-JZ0 ) ,so as to look for suitable edible fungus residue fertilizer formula and reduce those harms to the envi-ronment. The results showed that compared to CK-JZ0 treatment,the wheat yield decreased when the edi-ble fungus residue and cattle manure fertilizer application amount was 3 000 kg/ha or the ratio of edible fungus residue to cattle manure( JZD) was unsuitable;the wheat yield increased when the edible fungus residue fertilizer application amount was 6 000 kg/ha and 9 000 kg/ha respectively or the ratio of edible fungus residue to cattle manure( JZA,JZB,JZC) was suitable. Compared to CK-JZ0 treatment,there were successively increasing effects of JZB treatment on the height,total dry biomass,kernels number per spike of wheat and JZA treatment on kernels number per spike of wheat respectively,when the edible fungus fertilizer application amount was 6 000 kg/ha. And the yield of JZA treatment was 4. 7%higher than CK-JZ0. Similarly,there were successively increasing effects of JZA,JZB,JZC treatments on the height,length of spike,kernels number per spike of wheat,JZA treatment on kernels number per spike of wheat,and JZB and JZC treatments on yield respectively,when the edible fungus fertilizer application amount was 9 000 kg/ha. And the yields of JZB and JZC treatments were 6. 7% and 15. 9% higher than CK-JZ0 treatment respectively.
