Recently, the tobacco pest control innovation team of the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the tidal flat biological resource protection and utilization innovation team jointly carried out research, through the biocontrol bacillus and EM fermentation bacteria mixed compost fermentation, prepared to obtain the treatment of tobacco black shank and bacterial wilt.
Zanthoxylum bungeanum seed-based functional microbial fertilizers with good prevention and control effects have systematically analyzed the fermentation mechanism from the aspects of substance transformation, microbial community and function, and antibiotic resistance genes .
Relevant research results were published on "Bioresource Technology (Bioresource Technology)" .
Zanthoxylum bungeanum seed-based functional microbial fertilizers with good prevention and control effects have systematically analyzed the fermentation mechanism from the aspects of substance transformation, microbial community and function, and antibiotic resistance genes .
Relevant research results were published on "Bioresource Technology (Bioresource Technology)" .
Zanthoxylum bungeanum is a multi-purpose economic tree species with a long history of cultivation in China, such as edible seasonings, spices, oils, and medicinal materials.
The planting area in China is about 1.
152 million hectares and the annual output is about 459,000 tons
.
Its main utilization part is the mature husk, while the utilization rate of prickly ash seeds is low
.
The research team successfully made functional bio-organic fertilizer by adding biocontrol bacillus, fermentation bacteria and biochar co-composting to the nutrient-rich pepper seed oil meal
.
The study found that the addition of biocontrol Bacillus subtilis and fermentative bacteria significantly increased the NH4+-N, pH, bacterial abundance and fungal community diversity of the prickly ash seed oil meal compost, and at the same time reduced the relative abundance of carbon metabolism genes in the mature compost
.
The content of NH4+-N in compost is significantly related to the abundance and diversity of microorganisms, and its increase is caused by the increase of the amino acid metabolism pathway of the compost microorganism and the decrease of the amino acid biosynthesis pathway
.
This work not only improves the effective colonization of biocontrol bacteria, but also realizes the efficient use of agricultural waste prickly ash seed oil meal
