TECHNOLOGY FOCUS - BIOLOGY - Preferred Composition: The organic fertilizer comprises 100-120 pts. wt., preferably 100-105 pts. wt. of traditional Chinese medicine slag, 50-100 pts. wt., preferably 75-80 pts. wt. of straw, 10-40 pts. wt., preferably 17-20 pts. wt. of wheat bran, 1.6-7.8 pts. wt., preferably 3-4 pts. wt. of fungus liquid and 0.15-2.6 pts. wt., preferably 0.9-1 pts. wt. of bacteria liquid. Preferred Components: The traditional Chinese medicine slag is 8-12 pts. wt. of Angelica, 8-12 pts. wt. of radix codonopsitis, 8-12 pts. wt. of common Andrographis herb, 12-18 pts. wt. of leatherleaf Mahonia, 12-18 pts. wt. of philippline Flemingia root, 12-18 pts. wt. of cherokee rose or 12-18 pts. wt. of Spatholobus stem. The fungus liquid is Aspergillus niger, yeast or Trichoderma viride. The weight ratio of yeast and Trichoderma viride is 3:7-7:3, preferably 1:1. Preferred Method: The fungus liquid is prepared by culturing fungus seed liquid, Aspergillus niger, yeast and Trichoderma viride into a flat plate, inoculating cultured liquid into fresh potato dextrose agar (PDA) culture medium, shaking the culture at rotating speed of 120-180 revolutions per minute (rpm) and temperature of 30 degrees C for 40-60 hours to obtain fungus seed liquid, inoculating fungus seed liquid into PDA liquid culture medium at inoculum size of 0.3-0.8%, maintaining the temperature to 30 degrees C, and culturing at rotating speed of 120-180 rpm for 2-5 days. The bacteria liquid is prepared by taking slag discharging area beside of soil, inoculating bacteria seed liquid into lysogeny broth (LB) culture medium at rotating speed of 150-220 rpm and temperature of 37 degrees C for 10-30 minutes, pouring the supernatant into LB culture medium, shaking the culture at rotating speed of 150-220 rpm and temperature of 37 degrees C for 20-30 hours to obtain bacteria seed liquid, adding bacteria seed liquid is to LB liquid culture medium at inoculum size of 0.05-0.2%, maintaining the temperature to 37 degrees C, and culturing bacteria in soil at rotating speed of 150-220 rpm for 0.5-3 days.
