NOVELTY - Composition packed in bag comprises loess, peat, dairy manure, Viburnum utile, fructus cnidii, ammonium bicarbonate, vermiculite, hemlock, sweet potato powder, emblic leafflower fruit, sawdust powder, compound fertilizer, lily flower, konjac powder, lotus seed, calcium carbonate, broad bean shell, orange peel, pine sawdust, corn cob and organic manure fermentation agent.    USE - The composition packed in bag is useful for cultivating poplar sapling (claimed).    ADVANTAGE - The composition packed in bag utilizes waste as raw material, has good ventilation property and improves sapling survival rate.    DETAILED DESCRIPTION - Composition packed in bag comprises 40-45 pts. wt. loess, 10-30 pts. wt. peat, 5-7 pts. wt. dairy manure, 1-2 pts. wt. Viburnum utile, 0.2-0.4 pts. wt. fructus cnidii, 1-2 pts. wt. ammonium bicarbonate, 3-5 pts. wt. vermiculite, 1-2 pts. wt. hemlock, 3-6 pts. wt. sweet potato powder, 1-2 pts. wt. emblic leafflower fruit, 4-8 pts. wt. sawdust powder, 6-8 pts. wt. compound fertilizer, 1-2 pts. wt. lily flower, 1-2 pts. wt. konjac powder, 5-8 pts. wt. lotus seed, 0.3-0.5 pts. wt. calcium carbonate, 20-30 pts. wt. broad bean shell, 3-4 pts. wt. orange peel, 10-12 pts. wt. pine sawdust, 4-5 pts. wt. corn cob and 0.3-0.5 pts. wt. organic manure fermentation agent. The compound fertilizer comprises 3-6 pts. wt. urea, 1-2 pts. wt. lysine, 20-40 pts. wt. peanut cake powder, 0.5-1 pt. wt. zinc sulfate, 0.5-1 pt. wt. methyl methacrylate, 1-2 pts. wt. sodium nitrophenolate, 1-2 pts. wt. sodium molybdate dihydrate, 2-4 pts. wt. attapulgite, 1-2 pts. wt. rice hull powder, 3-5 pts. wt. cooking oil, 1-2 pts. wt. organic manure fermentation agent, 3-5 pts. wt. bamboo, 3-5 pts. wt. leftover biscuit, 3-5 pts. wt. mushroom residue, 1-2 pts. wt. broom cypress fruit, 2-3 pts. wt. clove, and 2-3 pts. wt. gypsum powder. The compound fertilizer is prepared by (a) uniformly mixing the components of fertilizer composition except cooking oil, attapulgite and gypsum powder, regulating water content of mixture to 42-45%, adjusting pH of the mixture to 5-6, and fermenting the mixture at 50-60 degrees C for 4-6 days, and (b) adding the cooking oil, attapulgite and gypsum powder to fermented product obtained in step (a), and granulating obtained product. An INDEPENDENT CLAIM is included for method for preparing composition packed in bag, which involves crushing the vermiculite and passing through sieve having 100-120 mesh, uniformly mixing V.utile, fructus cnidii and hemlock, immersing in white wine for 9-10 hours, taking out, draining, drying, grinding to obtain compound powder, uniformly mixing the lily flower, lotus seed, broad bean shell, orange peel and pine sawdust, crushing, adding loess, peat, dairy manure and organic manure fermentation agent, fermenting at 45-52 degrees C for 7-9 hours to obtain fermentation mixture, and mixing the fermentation mixture, compound powder, and the remaining raw material to obtain product.
