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.

Key words: morel, organic fertilizer, continuous cropping obstacle, increased production, stable production
