TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preparation (claimed): Producing efficient disease-resistant decomposable phosphorus bacterial manure for tobacco use comprises: (a) preparing the bacterial suspension: (i) choosing bacterium seed Pseudomonas choloraphis XQ902 CGMCC NO. 2324; (ii) cultivating bacterium seed on talus at 26-30 degrees C for 2-3 days; (iii) cultivating seed by shaking bottle: adding 100 ml culture medium in a 500 ml triangle bottle; sterilizing at 121 degrees C for 30-40 minutes; dipping in bacterium seed in 1-ring talus after cooling; cultivating by surging at 28-30 degrees C with shaking table turn speed of 190-210 rotations per minute (rpm) for 26-30 hours; and (iv) fermenting: adding 280 L of culture medium in a 400 L fermentation cylinder; sterilizing at 121 degrees C for 30-40 minutes; dipping in 28 L seed culture solution after cooling; cultivating by surging at 28-30 degrees C with stirring turn speed of 250-270 rpm for 48-50 hours with aeration ratio of 1:(0.5-0.8); obtaining bacterial suspension; (b) sterilizing for the adsorbent: water content of the adsorbent is 10-20%; crushing the adsorbent to 60-80 meshes; packing with 1-1.5 kg per clothes or plastic bag; sterilizing with high pressure of 0.1 MPa for 2-3 hours; bringing out and cooling for future use; and (c) inoculating and cultivating the adsorbent: placing the adsorbent in clean plastic clothes; adding 100 ml bacterial suspension in per 400-600 g adsorbent; stirring equably making water content to the extend of which forming as agglomerate when held by hand; dispersing when touched; cultivating the absorbent dipped with bacterial suspension at 20-30 degrees C for 2-7 days; making the bacterial propagate and the number of alive bacterial is no less than 100 million per/g of bacterial manure; packing and obtaining the products of efficient disease-resistant decomposable phosphorus bacterial manure. Preferred Bacterial Manure: In the efficient disease-resistant decomposable phosphorus bacterial manure above, the adsorbent is grass carbon, active carbon, vermiculite or its mixture. Preferably, the adsorbent is grass carbon; water content of the grass carbon is 10-20%; crushing the grass carbon to 60-80 meshes. About 100 ml of bacterial suspension is added into adsorbent per 400-600 g in the efficient disease-resistant decomposable phosphorus bacterial manure. The preparation method of the bacterial suspension is as follows: (a) choosing bacterium seed Pseudomonas choloraphis XQ902 CGMCC NO. 2324; (b) cultivating bacterium seed on talus at 26-30 degrees C for 2-3 days; (c) cultivating seed by shaking bottle: adding 100 ml culture medium in a 500 ml triangle bottle; sterilizing at 121 degrees C for 30-40 minutes; dipping in bacterium seed in 1-ring talus after cooling; cultivating by surging at 28-30 degrees C with shaking table turn speed of 190-210 rpm for 26-30 hours; and (d) fermenting: adding 280 L of culture medium in a 400L fermentation cylinder; sterilizing at 121 degrees C for 30-40 minutes; dipping in 28 L seed culture solution after cooling; cultivating by surging at 28-30 degrees C with stirring turn speed of 250-270 rpm for 48-50 hours with aeration ratio of 1:(0.5-0.8); obtaining bacterial suspension. The culture medium of cultivating bacterium seed on talus in (b) is as follows: 6-15 g of glucose, 80-120 ml of glycerine, 3-8 g of casein, 0.5-1.5 g of sodium bicarbonate (NaHCO3), 0.5-1.5 g of magnesium sulfate heptahydrate (MgSO4.7H2O), 2-3 g of potassium biphosphate (K2HPO4), 0.4-1 g of sodium laurylsulfate (SDS), 900-1200 ml of distilled water; the culture mediums of cultivating seed by shaking bottle in (c) and fermenting in (d) are as follows: 100-150 ml of corn hydrolysis liquid, 10-40 g of cane sugar, 2-6 g of dried silkworm chrysalis meal, 0.1-0.5 g of lecithin, 1-5 g of monopotassium phosphate (KH2PO4), 1-5 g of calcium carbonate (CaCO3), 0.1-0.5 g of magnesium sulfate (MgSO4), 1000 ml of water, 3-10 ppm of iron sulfate heptahydrate (FeSO4.7H2O), 3-10 ppm of manganese sulfate monohydrate (MnSO4.H2O), 3-10 ppm of compound vitamin.
