摘要:

为探索有机肥在六妹羊肚菌(Morchella sextelata)连作栽培中的应用技术,研究有机肥对土壤理化性质和羊肚菌产量的影响。通过向羊肚菌栽培土壤中施用麦秸鸡粪有机肥,并连续统计两年羊肚菌的产量和土壤理化指标变化情况,利用主成分分析方法寻找影响土壤理化指标的主要因素,利用相关性分析方法确定影响羊肚菌产量的关键土壤理化指标。施用有机肥显著改变了土壤理化性质,土壤肥力水平明显提升。羊肚菌栽培对土壤容重、pH值、腐殖酸、有机质、碱解氮、有效磷、有效钼、有效硼、交换性钙离子和交换性镁离子含量影响较大。施用有机肥可以连续两年提升羊肚菌出菇产量20%以上,具有一定增产、稳产的效果。羊肚菌产量与土壤腐殖酸和交换性钙离子含量呈显著正相关。研究展示了秸秆发酵有机肥在羊肚菌连作栽培中的应用潜力,揭示了影响羊肚菌产量的关键土壤理化指标。

Abstract:

This work aims to explore the application technology of organic fertilizer in continuous cultivation of morel(Morchella sextelata),and to study the effect of wheat straw fermented organic fertilizer on the soil physicochemical properties and yield of morel fruiting bodies. Fermented organic fertilizer with wheat straw and chicken manure was applied to morel cultivating soil. The morel yield and the soil physicochemical properties were calculated for two consecutive years. The main factors affecting soil physicochemical properties were determined through principal component analysis. The key factors affecting morel production was identified by correlation analysis. The application of this organic fertilizer significantly changed the soil physicochemical properties,and significantly improved sandy soil fertility levels. Morel cultivation had obvious influences on the soil bulk density,pH value,as well as the contents of humic acid,organic matter,alkali-hydrolyzed nitrogen,available phosphorus,available molybdenum,available boron,exchangeable calcium ion,and exchangeable magnesium ion. The organic fertilizer increased the fruiting yield of morel by over 20% for two consecutive years,showing an effect of increasing and stabilizing the yield. Morel production was significantly and positively correlated with the contents of soil humic acid and exchangeable calcium ion. The study showed the application potential of crop straw fermented organic fertilizer in the cultivation of morel,and revealed the key soil physiochemical properties affecting the yield.
