NOVELTY - Nutrition material comprises 20-30 pts. wt. straw fermenting material, 20-30 pts. wt. peat soil, 5-10 pts. wt. nitrogen-fixing bacteria, 3-5 pts. wt. organic matter decomposing bacteria, 5-10 pts. wt. fiber framework, 10-30 pts. wt. humic acid, 10-30 pts. wt. fulvic acid, and 3-5 pts. wt. green Trichoderma.    USE - The nutrition material is useful for engineering, greening and planting soil (claimed).    ADVANTAGE - The nutrition material: can greatly increase capacity of greening soil nutrition; can digest and absorb solid waste in plant growth process to obviously improve the landscape of engineering; and is suitable for greening.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the nutrition material, comprising (a) preparation of the straw fermenting material: collecting plant straw, crushing through a straw crusher into fragments of 1-2 cm, adding the straw fragments in 5% sodium hydroxide solution according to solid-liquid ratio of 1:4, soaking at room temperature for 20-40 hours, then conveying into a fermentation tank, adjusting the pH of the mixed liquid to 9, adding 2.5-4 wt.% Aspergillus niger to ferment for 4-5 days, filtering to obtain filtrate, concentrating the filtrate, and then subjecting to spray-granulation to obtain the straw fermenting material; (b) taking each enrichment culture microflora, culturing, concentrating, and centrifuging to obtain the organic matter decomposing bacteria, nitrogen-fixing bacteria and green Trichoderma; and (c) then uniformly mixing the straw fermenting material, peat soil, fiber framework, humic acid and fulvic acid, then adding the organic matter decomposition bacteria, nitrogen-fixing bacteria and green Trichoderma strain to obtain the nutrition material; and (2) use of the nutrition material in greening of engineering, comprising directly preparing the nutrition material as greening plant growth medium or as soil additives for adding the soil as greening plant growing medium.
