Study on maize straw and pig manure compost in packing bags

To study the best technical parameters of maize straw and pig manure compost in packing bags, orthogonal test was designed with different C/N , fermenting inoculum and moisture content of maize straw and pig manure. The formula, which was C/N 25~35：1 , fermenting inoculum Bio and moisture content 40%~55% , was the optimum formula of maize straw and pig manure composting in packing bags. The organic matter decreased slightly, but the total phosphorus and potassium were increased at the end of the compost. The toxicity tests showed that each test reached maturity. Packaged composting gave a good way to comprehensive utilization of little agricultural wastes .
