Organic water-soluble fertilizer and preparation method and application thereof

Abstract

The invention discloses organic water-soluble fertilizer and a preparation method and application thereof. The preparation method includes the steps of 1, preparation, wherein various pure natural food materials including bean pulp, milk powder, cinnamon, crustacea bone meal, magnesium oxide, milt, humic acid and molasses are blended with a biological fermentation agent and water according to a proportion to form a nutrient solution; 2, stirring, wherein intermitted air stirring is performed for 15 min every 1-5 h, then the mixture is put into a fermentation vat and subjected to standing and storing in a sealed mode for 7-35 d to be fermented, and then the organic water-soluble fertilizer is obtained; 3, application, wherein the application amount is 3-4 kg / mu if a flushing application mode is adopted, the application amount is 2-4 kg / mu if a sprinkling and dropping irrigation mode is adopted, the fertilizer should be diluted by 500 folds and applied according to the application amount of 1-3 kg / mu every time if a root irrigation mode is adopted, the fertilizer should be diluted by 800-1500 folds and applied according to the application amount of 0.5 kg / mu every time if a foliar spraying application mode is adopted, and meanwhile the fertilizer is applied one time every 10-15 d according to the growing period of crops.

Description

technical field [0001] The invention belongs to the field of production, manufacture and application of organic fertilizers, and in particular relates to an organic water-soluble fertilizer and its preparation method and application. Background technique [0002] Over the past 60 years, with the development of agriculture, a large amount of chemical fertilizers and pesticides have been invested in crop planting in pursuit of quick success, labor saving, low cost, and high profit. Chemical fertilizers are used in large quantities by farmers because they are cheap, readily available and easily absorbed by crops. However, in the process of use, due to the continuous application of chemical fertilizers, the organic matter content of the farmland soil has decreased, the soil structure has been severely damaged, soil compaction has increased, the aeration has been poor, water and fertilizer retention capacity has decreased, and soil productivity has decreased significantly; moreov...

Problems solved by technology

However, due to the insufficient development and utilization of organic fertilizer sources at present, the number of them is limited. At the same time, the application methods of organic fertilizers need to be continuously improved, and the technical level and resource utilization rate should be improved.
