NOVELTY - Multivariant compound microbial fertilizer is processed by preparing powder mixture of rice husk, wheat husk, vinasse, fungi slag, chitosan, peat, bagasse, plant ash, and saw dust; absorbing fermented algae liquid in powder mixture; mixing absorbed single algae agent; selecting at least one of peat and lignite as third sample; absorbing fermented fungi liquid in third sample; mixing absorbed single fungi agent; and taking (wt.%) absorbed single algae agent (10-55), absorbed single fungi agent (35-90), and animal product excrement (0-8) to prepare final product.    USE - Multivariant compound microbial fertilizer.    ADVANTAGE - The multivariant compound microbial fertilizer has easily obtained material source, low production cost, stable performance, lasting fertilizer effect, and high biology validity. It fastens decomposing of crop straw, increases supply of available nutrient, improves physical and chemical properties of soil, promotes plant growth, improves crop yield, and improves quality of farm product.    DETAILED DESCRIPTION - Multivariant compound microbial fertilizer is processed by selecting at least one powder of rice husk, wheat husk, vinasse, fungi slag, chitosan, peat, bagasse, plant ash, and saw dust; mixing uniformly; filtering by 0.1-2 cm sieve to prepare first sample; fermenting Chroococcus Gardner, Chlamydomonas sajao Lewin, Eunotia lunaris, Chlorella vulgaris and Anabaena azotica, absorbing fermented algae liquid in 3-12 fold of first sample; mixing five absorbed single algae agent at ratio of 5-55:0-35:0-30:10-50:0-35 to prepare second sample; selecting at least one of peat, lignite, zeolite, calcium carbonate, montmorillonite, kieselguhr, vermiculite, pulverized fuel ash, and bentonite; mixing uniformly and filtering by 0.1-2 cm sieve to obtain third sample; fermenting Bacillus subtilis, Rhodopseudanonas palustris, Bacillus megaterium, Streptomyces jingyangensis, and Bacillus mucilaginosus; absorbing fermented fungi liquid in 2-10 fold of third sample; and mixing single fungi agent at ratio of 10-55:0-30:10-50:0-25:0-35 to prepare fourth sample; and taking (wt.%) second sample (10-55), fourth sample (35-90), and animal product excrement (0-8) to prepare final product.
