摘　　要：【目的】探究菌渣还田对反季节栽培淮山产质量及土壤养分的影响,为淮山高产优质栽培和菌渣合理还田提供理论依据。【方法】以那淮1号为试验材料,设置4个不同的试验处理:T1(菌渣)、T2(有机肥)、T3(菌渣+有机肥),CK(空白对照)。【结果】不同处理能显著提高淮山产量,T3的产量最高,达39328.63 kg·hm^(−2),T1、T2、T3分别较CK增产15.53%、17.92%、26.53%;不同处理能够显著提高淮山块茎淀粉含量,T3最高,达到30.84%,显著高于其他处理;氨基酸含量为2.38~2.47%;可溶性糖含量以T2最高;总皂甙含量与淀粉含量的变化趋势基本一致,以T3最高,达0.46 mg·g^(−1);T1、T2、T3淮山叶片叶绿素含量在出苗后10~160 d不同生长期均比CK高,其中T3的叶绿素含量最高,下降最缓慢;T1、T2、T3均能提高土壤碱解氮、有效磷、速效钾和有机质含量,其中T3能显著提高土壤碱解氮、速效钾、有机质含量及土壤pH值。【结论】菌渣+有机肥(T3)处理优于单菌渣或生物有机肥还田,能显著提高淮山产量,改善淮山品质,改良土壤性状。【Objective】Effects of returning mushroom discards to the field on soil and quality and yield of off-season cultivated yams were investigated.【Method】In a field experimentation Nahuai No.1 yams were planted off-season on lots added with mushroom discards(T1),an organic fertilizer(T2),mushroom discards+an organic fertilizer(T3),or blank control(CK)to determine the quality and yield of the yams grown on them.【Result】The treatments significantly increased the tuber yield over CK with T3 delivered the greatest at 39,328.63 kg·hm^(−2),which was significantly higher than other treatments—T1 increased by 15.53%,T2 by 17.92%,and T3 by 26.53%.The starch content in the tubers increased with T3 producing the significantly highest at 30.84%;the amino acids ranged between 2.38%and 2.47%;the highest soluble sugars came from yams grown on T2;the highest saponin among all at 0.46 mg·g^(−1);and the leaf chlorophyll heightened in 10-160d after emergence with the highest peak value and the slowest on declining under T3.The treatments,especially T3,also altered the soil nutrients increasing the available nitrogen,phosphorus,potassium,and organic matters,while balanced the pH.【Conclusion】By returning mushroom discards with added organic fertilizer to the soil,T3 significantly improved the yield and quality of the yams grown on the treated land.
