Natural yeast fermentation process of wine based on diversity cultivation of soil organisms

Abstract

The invention relates to a natural yeast fermentation process of wine based on diversity cultivation of soil organisms. The process comprises the following steps: (1) improving soil: composting strawsand livestock excrement for 5 months, and carrying out fermentation under an aerobic condition; carrying out fertilization, wherein the physical and chemical properties of soil are good, nutrients are balanced, and the soil fertility is stably supplied; carrying out deep excavation so as to loosen the soil, and supplementing microelements such as zinc and boron required by grapes; planting leguminous crops such as oat and alfalfa in an orchard so as to assist loosening of the soil and increasing of supply of a nitrogen fertilizer; culturing soil microorganism flocks, so as to effectively absorb mineral substances and trace mineral elements; (2) planting high-quality wine-making grapes; and (3) fermenting the wine. The natural yeast fermentation process has the advantages that by plantingnitrogen-containing plants, nitrogen content in the soil is increased, and growth of grape vines is guaranteed; by carrying out composting, soil organic matters are increased, and soil microorganismsare cultured, so that the capillary roots are assisted to effectively absorbing the mineral substances; and grapes are fermented by virtue of natural yeast florae, so that oxidation of the wine is effectively prevented in the premise that sulfur dioxide is not added.

Description

technical field [0001] The invention relates to the field of wine natural yeast fermentation, in particular to a wine natural yeast fermentation process of soil biological diversity cultivation. Background technique [0002] Biodiverse environments include vegetation, organisms, animals, birds, insects. The natural ecological chain is closed, reducing human intervention and using chemical pesticides to prevent pests and diseases. [0003] A Biodiversity environment at the eastern foot of Helan Mountain [0004] (1) The main plants include 25 species of Poaceae, 20 species of Asteraceae, 18 species of Leguminosae, 7 species of Cyperaceae, and 4 species of other families. Gramineae, Compositae, and Leguminous plants are the most, especially 24 species of Artemisia in Helan Mountain. Grassland types: (a) Desert grasslands account for 50.7% of the city's total natural grassland area. The main constructing species and dominant species are Stipa breviflora, Convolvulus thorns, ...

AI Technical Summary

Problems solved by technology

[0018] The Helan Mountain in Ningxia's Million Mu Corridor is located on a high slope of 1300 meters above sea level along the mountain. The soil is mainly light lime calcium soil and aeolian sandy soil. Its characteristics: 1. It is relatively barren. Fe, Zn, and B are all deficient; 2. Organic matter and total N content are low; 3. pH value ≧ 8, which affects the absorption of certain nutrients; 4. Microbial flora is less and has a single function

If chemical fertilizers are used alone, the soil fertility will decline year by year, the compaction will be serious, and the microbial flora will be less
