TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In preparing compost inoculants, step (b) comprises adding the composted sludge composting water extract solution with 1 to 5-20 of extracting ratio according to 5-10% of volume ratio, disinfecting and cooling to 45-55 degrees C, vaccinating the activated UTM02 strain, shaking culturing for 1-3 days at 65-70 degrees C, where the shaking frequency is 150-200 revolutions per minute (rpm); the composition of the medium is as follows: 3-5 g beef extract, 10 g peptone, 3-5 g sodium chloride, and 1000 ml water, and the pH value is 7.2-7.4. Step (c) comprises vaccinating the seed solution of the step (b) in the seed tanking containing with the disinfected medium according to 3-10% of volume ratio, at 65-70 degrees C, airing for 10-30 minutes every 3-6 hours, where the ventilatory capacity volume ratio is 0.5-1.5-1, stirring at 150-200 rpm, and culturing for 2-5 days. Step (d) comprises mixing the wet basis and the dry basis to 20-30 to 1 of nitrogen and carbon ratio, 0.1-0.5% of compost total weight, adding the carbon source, and keeping the moisture content at 50-65%. The organic waste wet basis in step (d) is one or more of the poultry excrement, and the municipal sludge; the organic waste dry basis is one or more of the sawdust, peanut shell powder, furfural and the sugar slag; and the carbon source is the brown sugar or the molasses. The piling fermenting method of step (d) is as follows: without airing at the first 6-24 hours of the piling, force airing, blowing for 20-40 minutes every 1-3 hours, where the ventilatory capacity is 0.03-0.06 m3/(minute-m3), monitoring the change of the temperature every day, reaching to 45-55 degrees C of the compost, 0.08-0.20 m3/(minute-m3) of ventilatory capacity, reaching to 70 degrees C of central temperature of the compost body, taking 0.1-0.5% of the piling material weight of fermented seed solution, using the corn starch and the wheat bran to absorb, uniformly spraying on the surface of the piling body, turning the pile, continuing to pile for 5-10 days, turning the pile for 1-3 times during the period, stirring for once 2-4 days before discharging, taking out the material, aging and airing, reducing to the moisture content to less than 30%, and sieving the aging material to obtain the inoculants. ACTIVITY - Fungicide.
