DETAILED DESCRIPTION - Material comprises 50-55 pts. wt. of cotton seed hull, 20-25 pts. wt. of bagasse, 18-22 pts. wt. of straw, 19-20 pts. wt. of soybean meal, 10-12 pts. wt. of rice bran, 18-19 pts. wt. of pine needle powder, 10-12 pts. wt. of maggot powder, 11-13 pts. wt. of fresh soybean curb residue, 8-9 pts. wt. of bentonite, 4-5 pts. wt. of notoginseng, 3-4 pts. wt. of kudzu leaf, 5-6 pts. wt. of medlar, 7-8 pts. wt. of Cassia root, 2-3 pts. wt. of white Perilla leaf root, 0.1-0.2 pts. wt. Cinnamon oil, 3-4 pts. wt. of royal jelly, 2-3 pts. wt. of lime powder, 1-2 pts. wt. of brown sugar, 2-3 pts. wt. of salt and 5-6 pts. wt. of nutrient additive. The nutrient additive comprises 0.1-0.2 pts. wt. of Magnolia flower oil, 1-2 pts. wt. of jade, 2-2.5 pts. wt. of bracken, 0.9-1.2 pts. wt. of rock broom (Genista), 10-11 pts. wt. of diatomite, 0.1-0.15 pt. wt. of ammonium polyphosphate, 0.09-0.1 pts. wt. of zinc chloride and 5-6 pts. wt. of biogas slurry. The nutrient additive is prepared by adding the jade, bracken, rock broom and diatomite into biogas slurry, drying and crushing into a crusher, and then mixing with the residual materials. An INDEPENDENT CLAIM is included for preparing the material comprising (1) adding the brown sugar and salt with 5-6 times of water, heating and stirring until it is completely dissolve and cooling, and then adding royal jelly and lime powder, (2) adding the straw, kudzu leaf, medlar, Cassia root, white Perilla leaf into the crusher for crushing, then stirring for 20-25 minutes by stirrer, mixing bagasse, cotton seed hull and rice bran, adding water to wet for 2-3 hours and controlling the moisture content to 55-60%, (3) mixing obtained material with remaining raw materials, until the moisture content is 60-65%, (4) placing the obtained material into a bag and sterilizing the material at 100 degrees C under normal pressure.
