Abstract:

To evaluate the potential of co-composting of edible fungus chaff and chicken manure to improve saline-alkali soil, we studied the physical index of co-composting of agaric fungus chaff and chicken manure, and determined the growth index of garlic seedlings by cultivating garlic in saline-alkali soil with mixed fertilizer. The results showed that: the growth index of garlic seedlings in saline-alkali soil with a certain proportion of agaric fungus chaff (control group) was better than that in saline-alkali soil without agaric fungus chaff (blank group), with significant difference (P<0.05); the growth index of garlic seedlings in saline-alkali soil with agaric fungus chaff and chicken manure (fermentation group) was better than that in saline-alkali soil with agaric fungus chaff (control group) only, with significant difference (P<0.05), and was also better than that without agaric fungus chaff (blank group) with very significant difference (P<0.01). Through the analysis of interactive experimental data, the optimum condition for co-composting was determined as: 15% fungus chaff, 8% chicken manure and 45% water content. Therefore, adding co-composting of agaric fungus chaff and chicken manure in saline-alkali soil can increase the crop yield, and is of practical significance for the efficient utilization of agricultural wastes and the protection of ecological environment.

Key words: improving saline-alkali soil, organic fertilizer, agaric fungus chaff, chicken manure, fermentation improvers, composting
