Abstract: In order to improve the utilization rate of agricultural and forestry waste, reduce dependence on fertilizer to crop cultivation, forestry waste composting fermentation substrate for cultivating the matrix, by the method of field experiment, the growth of winter wheat was effect contrast tests showed that: compared with common wheat fertilizer and chemical fertilizer, organic composite cultivation medium enhanced the growth of wheat, organic composite growing substrate promoted significantly on wheat spike length, spike number, output growth compared with common wheat fertilizer and fertilizer. Among them, the average wheat spike length than no fertilizer increased by 8.90% , growth of 5.85% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 5.49%; the average wheat spike number than no fertilizer increased by 40.79%, growth of 17.11% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 2.63%; the average yield of wheat growth of 34.78% than no fertilizer, growth of 7.89% than the chemical fertilizer, compared with the single application of ordinary fertilizer for wheat growth of 2.01%. The research can provide a reference for the agricultural and forestry waste utilization in crop cultivation area.
