A decomposing substrate using xylose residues as a raw material is obtained by fermenting the following raw materials: 0.5-2 wt% of fermented composite bacteria, 75-85 wt% of xylose residues, 5-10 wt%of straws, 0.5-2 wt% of potassium nitrate, 1-10 wt% of plant ash and 1-5 wt% of a waste sugar solution. The decomposing substrate can be used as an organic fertilizer or an ingredient for preparing amicrobial fertilizer and a seedling growing substrate. The decomposing substrate using xylose residues as the raw material has the advantages of richness in various beneficial microorganisms, easilyavailable raw materials, low cost, no harmful substances and short decomposing time. The decomposing substrate has high content of the beneficial microorganisms, and has lignin and cellulose degradingand phosphorus dissolving effects. The seedling growing substrate prepared from the decomposing substrate has the advantages of high content of organic matters, richness in various beneficial microorganisms, reduction of the seedling growing cost, and improvement of the emergence rate and the regularity.

The invention provides a preparation method of a microbial fertilizer for preventing and controlling sugar orange anthracnose. The fertilizer is mainly prepared from mushroom dreg compost, vermiculite, a nitrogen-phosphorus-potassium fertilizer and water. When the vermiculite is added into the fertilizer, various nutrient elements in the fertilizer, particularly trace elements can be released slowly, and nutrition can be supplied to sugar orange in a whole growth period; at the composting stage of mushroom dreg, a specially-made mixed strain is adopted, so that a good composting effect is achieved; compared with the conventional method, the preparation method has the advantages that over a half of time is shortened, the cost is lower, and a better effect is achieved; in a formula of the microbial fertilizer, other raw materials such as trace elements other than the mushroom dreg compost, the vermiculite, the conventional nitrogen-phosphorus-potassium fertilizer and water do not need to be added, so that the microbial fertilizer is low in cost. In conclusion, the fertilizer provided by the invention has the advantages of low cost, high mushroom dreg utilization rate, and remarkable prevention and control effects on the sugar orange anthracnose.
