Application effect of compound microbial agents promoting crop straw and sclerotia decomposition
摘要
Abstract
To effectively decay crop straw and rapeseed pathogen(sclerotia of Sclerotinia sclerotiorum),2 fun-gi(Aspergillus aculeatus,Trichoderma harzianum)and 1 bacteria(Bacillus subtilis)were used in pot experiments. A. aculeatus strain Asp - 3 and T. harzianum strain Tri - 5 were made into conidium suspension(compound liquid inoculants,CLI)to study their decomposing effects. T. harzianum strain Tri - 5 and B. subtilis strain Tu - 100 with decompose rapeseed meal and straw were used as compound bio - fertilizer(CBF). Results showed that compared to the matrix control,after CLI spray,rape straw decomposition rate increased 15. 07% ,and sclerotia germination rate decreased 20. 98% . After using CBF,rice straw decomposition rate increased 5. 81% ,and sclerotia germina-tion rate decreased 12. 28% . Soil acid phosphatase and urease activities increased and sclerotia germination rate decreased significantly after using CBF and CLI. Rapeseed yield was also significantly increased after using CBF with rice straw,with the yield 9. 6% higher than that of blank control.关键词
