Popis: | This study explored the differences among various artificial morel cultivations as well as the factors that influence these differences, including soil bacterial community structure, yield, and mineral element contents of ascocarp and the cultivated soil. High-throughput sequencing results revealed that the dominant bacterial phyla in all the samples, including Proteobacteria, Acidobacteria, Chloroflexi, Bacteroides, and Gemmatimonadetes, were found not only in morel soils (experimental group) but also in wheat soil (control group); the highest richness and diversity in the soil bacteria were observed during the primordial differentiation stage. The M6 group exhibited the highest yield (271.8 g/m2) and had an unexpectedly high proportion of Pseudomonas (25.30%) during the primordial differentiation stage, which was 1.77∼194.62 times more than the proportion of Pseudomonas in other samples. Pseudomonas may influence the growth of morel. The mineral element contents of the different soil groups and the ascocarp were determined by electrothermal digestion and inductively coupled plasma mass spectrometry. The results revealed that morel had high enrichment effects on phosphorus (P, bioconcentration factor = 16.83), potassium (K, 2.18), boron (B, 1.47), zinc (Zn, 1.36), copper (Cu, 1.15), and selenium (Se, 2.27). P levels were the highest followed by Se and K, and the mineral element contents in ascocarp were positively correlated with the soil element contents. |
