The Effect on Fermentation of Cassava Stalk Substrate Resulting from Two Microbial
The effect on fermentation of cassava stalk substrate resulting from thermophilic bacteria and fermenting bacteria for organic waste by six different kinds of treatments(cassava stalk,cassava stalk + thermophilic bacteria,cassava stalk + fermenting bacteria for organic waste,cassava stalk + chicken manure,thermophilic bacteria + cassava stalk + chicken manure,fermenting bacteria for organic waste + cassava stalk + chicken manure) was studied.When the cassava stalk substrate was composting in the ponds monitored the physic and chemical indices,including composting temperature,total carbon(TC),total nitrogen(TN),value of TC divided TN,pH,total phosphorus(TP),total potassium(TK),electrical conductivity(EC) and other physics properties.Results indicated that both thermophilic bacteria and fermenting bacteria for organic waste could accelerate the cassava stalk substrate maturing,but some differences of maturing time existed among treatments.In addition,not so many differences of maturing effect existed resulting from thermophilic bacteria and fermenting bacteria of organic waste.All results judged by the physical and chemical indices comfirmed cassava stalk fermented with thermophilic bacteria and fermenting bacteria of organic waste was an ideal substrate and worthy further studying.
