NOVELTY - Preparation of organic acid soil conditioner involves 1) evaporating, concentrating and filtering fermented white spirit yellow water, 2) adding glucose to yellow water, followed by adding ammonium sulfate, potassium dihydrogen phosphate, magnesium sulfate heptahydrate, manganese sulfate, water, sodium chloride and calcium carbonate; mixing and dissolving at high temperature sterilizing, 3) sterilizing yeast liquid mixed bacteria fermentation liquid, fermenting for 24-48 hours, where the mixed bacteria fermentation liquid includes e.g. swamp red Pseudomonas.    USE - For preparation of organic acid soil conditioner (claimed) used as microbial organic fertilizer.    ADVANTAGE - The organic acid soil conditioner has rich in organic acid, can effectively neutralize and relieves soil alkaline, can promote root growth, the crop seedlings orderly, seedling, and the plant can grow and increase wide on the land. The plant mucus, mineral blank and organic colloid combined together, can improve the soil granule structure, provides enhanced physical performance of the soil and reduces the loss of the soil particles. Administering the microorganism fertilizer can improve soil physical property, which is good for improving the soil fertility. The product can replace chemical fertilizer and pesticide, or can reduce agricultural pollution, but also can improve the quality of the agricultural commodity. The product can promote the soil mass, improves soil structure, improves soil fertility, promotes the growth of crops. By microorganism nitrogen fixation function, which can improve nitrogen synergist for fertilizing straw soil level, which can effectively improve the soil in some organic components of metabolic activity, sulfide and ammonia nitrogen, and promotes harmful pollutant such as conversion of farm chemical. At the same time promotes proliferation of beneficial microorganism to make it together in substance circulation of soil ecology. The conditioner can reduce the production cost of farmers, improves crop yield, and increases the income of the farmer. The conditioner not only can balance, growth and stimulate root growth of crops, improve soil, increasing crop yield and soil fertility, improving crop quality, but also can increase immunity of crops, improve disease resistance, drought, water, cold resistance. At the same time also reduces the discharge of the waste water, wine making by-product can be effectively recycle and utilize the waste, which is changed into treasure, reduces environmental pollution, and has good ecological benefit, economic benefit and development prospect.    DETAILED DESCRIPTION - Preparation of organic acid soil conditioner involves 1) evaporating, concentrating and filtering fermented white spirit yellow water, 2) adding glucose to yellow water, followed by adding ammonium sulfate (NH4)2SO4, potassium dihydrogen phosphate (KH2PO4), magnesium Sulfate heptahydrate (MgSO4-7H20), manganese sulfate (MnSO4), water (H2O), sodium chloride (NaCl) and calcium carbonate (CaCO3); mixing and dissolving at high temperature sterilizing, 3) sterilizing yeast liquid mixed bacteria fermentation liquid, fermenting for 24-48 hours, which is carried out in a bottle by sterile filling machine. The mixed bacteria fermentation liquid includes swamp red Pseudomonas, Pseudomonas fluorescens, brown spherical solid nitrogen bacteria for methane, Bacillus megatherium and Bacillus mucilaginosus. The weight percentage of Rhodopseudomonas palustris Pseudomonas, Pseudomonas fluorescens, brown spherical nitrogen fixing bacteria, inoculum concentration of Bacillus megatherium and Bacillus mucilaginosus is 2-5%, 2-5%, 2-5%, 5-10% and 5-10% of the yeast liquid weight.
