TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The organic fertilizer component comprises soybean meal, rapeseed, and flue-cured tobacco powder compost. The mass ratio of soybean meal, rapeseed, and flue-cured tobacco powder compost is 6:3:1. The microbial component comprises Bacillus subtilis, Bacillus megaterium, Trichoderma harzianum and Streptomyces hygroscopicus. A mass ratio of Bacillus subtilis, Bacillus megaterium, Trichoderma harzianum and Streptomyces hygroscopicus is 4:2:1:10. Preferred Process: The composite microbial component is prepared by: culturing Bacillus subtilis and Bacillus megaterium in an inclined plane culture medium, then fermenting to obtain a fermentation liquid, and then concentrating and drying to obtain Bacillus spore powder; culturing Trichoderma harzianum in an inclined plane culture medium, then fermenting to obtain a fermentation liquid, and then concentrating and drying to obtain Trichoderma harzianum spore powder; culturing Streptomyces hygroscopicus in an inclined plane culture medium, then fermenting to obtain a fermentation liquid, and then concentrating and drying to obtain Streptomyces hygroscopicus spore powder; and mixing the Bacillus spore powder, the Trichoderma harzianum spore powder, the Streptomyces hygroscopicus spore powder, and water-absorbing powder in a ratio of 4:2:1:1 to obtain the composite microbial component. The organic fertilizer component is prepared by: uniformly mixing the soybean meal, the rapeseed and flue-cured tobacco powder, regulating the water content to 60%, then fermenting for 40-60 days in a fermentation stack, where the fermentation stack center temperature is more than 50 degrees C, removing the film when the fermentation stack center temperature is more than 65 degrees C, properly adding water to ferment for 20 days, and repeating the operations until the fermentation stack temperature is reduced to 40 degrees C to obtain organic fertilizer component with grey brown color and without any odor.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The inorganic fertilizer component comprises 46 wt.% of urea, 45 wt.% of potassium sulfate and 53 wt.% of calcium superphosphate. A mass ratio of urea, potassium sulfate and calcium superphosphate is 18.8-29.7:8.1-17:8.2-15.7. ACTIVITY - Fertilizer; Antibacterial; Fungicide.
