DETAILED DESCRIPTION - Cold season lawn fertilizer comprises 45-55 pts. wt. livestock and poultry excrement, 25-35 pts. wt. animal waste residue, 15-20 pts. wt. mushroom residue, 14-18 pts. wt. broad bean shell, 10-15 pts. wt. melon vine, 12-16 pts. wt. soybean curd residue, 10-15 pts. wt. bone glue waste residue, 8-14 pts. wt. yellow bean, 6-12 pts. wt. amino acid residue, 10-15 pts. wt. bamboo forest soil, 5-10 pts. wt. blue-green algae, 4-8 pts. wt. egg shell powder, 5-10 pts. wt. rice water, 3-7 pts. wt. tea residue, 4-8 pts. wt. bamboo charcoal powder, 5-10 pts. wt. bronze powder, 12-16 pts. wt. modified attapulgite, 5-10 pts. wt. humic acid, 10-15 pts. wt. phosphoric acid, 7-13 pts. wt. light calcium carbonate powder, 4-6 pts. wt. potassium sulfate, 5-10 pts. wt. limestone powder, and 3-5 pts. wt. actinolite. The modified attapulgite is prepared by sieving attapulgite, then adding 1-2 mol/L copper sulfate solution and 0.5-1 mol/L silver nitrate solution, then heating to 40-80 degrees C, preserving heat for 12-24 hours, filtering and drying filtrate to obtain treated attapulgite; uniformly mixing 2-4 wt.% azalea, 1-2 wt.% larkspur, 0.5-1.5 wt.% poplar leaves, 2-3 wt.% semen pharbitidis, 1-2 wt.% Pseudolarix, and 1.5-2.5% pepper leaf, adding 2 times boiling water and extracting twice, combining extraction liquids, filtering, concentrating and freeze-drying into powder; and adding 30-40 wt.% soluble chitosan into 3-5 times 5% acetic acid solution, then adding 10% sodium hydroxide solution to adjust pH to neutral, and adding the freeze-dried powder and uniformly stirring to obtain slurry; and uniformly spraying the slurry on the treated attapulgite, drying and cooling to room temperature. An INDEPENDENT CLAIM is included for preparation of the lawn fertilizer, comprising:    (A) uniformly mixing livestock and poultry excrement, mushroom residue, broad bean shell, bone glue waste residue, and soybean curd residue, adding 100 times of 2-3% Effective Microorganisms probiotic diluting liquid, uniformly stirring, then adding water and controlling water content to 50-60%, and compost fermenting for 4-5 days at 46-52 degrees C;    (B) adding fermented material with 1-1.5 wt.% neutral cellulase and 0.5-1 wt.% neutral protease, uniformly stirring and performing secondary compost fermenting for 5-7 days at 40-45 degrees C;    (C) adding secondary fermented material with bamboo forest soil, blue-green algae, egg shell powder, rice water, and tea residue, uniformly stirring, performing third compost fermenting for 2-3 days at 58-64 degrees C; and    (D) drying third fermented material till the water content is 2-3%, crushing, sieving, adding rest raw materials, uniformly mixing, granulating, drying, and packaging to obtain the finished product.
