木耳菌糠和鸡粪混合堆肥改良盐碱土壤效果评价

为了评价食用菌菌糠和鸡粪混合堆肥改良盐碱土壤的潜力。笔者研究了木耳菌糠和鸡粪混合堆肥的物理指标,并用混合肥施用盐碱土壤栽培大蒜,测定大蒜苗的生长指标。结果表明：添加一定比例木耳菌糠的盐碱土壤栽培大蒜（对照组）,大蒜苗生长指标好于不添加木耳菌糠的盐碱土壤（空白组）,差异显著(P<0.05);添加木耳菌糠和鸡粪的盐碱土壤栽培大蒜（发酵组）,大蒜苗生长指标好于仅添加木耳菌糠的盐碱土壤（对照组）,差异显著(P<0.05),也明显好于不添加木耳菌糠的盐碱土壤（空白组）,差异极显著(P<0.01)。通过交互试验数据分析,混合堆肥的最佳条件：菌糠添加量15%,鸡粪添加量8%,堆肥含水量45%。由此说明,盐碱土壤添加木耳菌糠和鸡粪混合堆肥物,不仅能够有效提高农作物产量,而且对于农业废弃物资源高效利用和保护生态环境具有重要的现实意义。

Co-composting of Agaric Fungus Chaff and Chicken Manure: Improving Effect on the Saline-alkali Soil

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.
