Abstract:
Blue potted flowers was used as experimental.The corn stalk biochar was applied to the soil by 0,10,20,30,40 g?kg-1.The effects of the corn stalk biochar on the growth of blue potted flower and fungal abundance in the rhizosphere soil were studied,in order to provide some scientific basis for garden plant to use biochar relieving drougt stress.The results showed that with the increase of drought stress，plant height，stem diameter，root coefficient and root weight of T2 were significantly higher than those of CK，after 20 days of treatment，which were 26.23%，17.79%,26.67% and 13.93% higher than those of CK.The morphological indexes of blue potted flowers under T1 and T3 treatments were not significant with CK.Under T4 treatment,the plant height，stem diameter，root coefficient and root weight of blue potted flowers were significantly lower than those of CK.At the same time，biochar treatment of soil increased the abundance of soil fungi under drought stress.With the increase of biochar content，in the classification of soil，the Ascomycota,Basidiomycota，Zygomycota，Chytridiomycotaand Glomeromycota，as well as the classification of the genus Ascomycete,unclassified or unidentified,Chaetomiaceae,Microascaceae,Lasiosphaeriaceae，Nectriaceae,Herpotrichiellaceae,Pleosporaceae,Agaricaceae,Mortierellaceae and Sporormiaceae,the proportion of the community of the genus Basidaceae，which have a parabolic change.Under drought stress，the role of Ascomycetes，Capreolaceae，Trichosanthes，and Mycobacterium sphaeroides in promoting the growth of blue potted flowers was significant.The effect of drought stress on the growth of blue potted peanut was most alleviated by applying 20 g?kg-1 biochar in soil.
