Method for preparing organic fertilizer for planting tomatoes

Abstract

The invention discloses a method for preparing an organic fertilizer for planting tomatoes. The method comprises the following steps: (1) powdering, namely drying organic raw materials till the water content is 10-14%, performing powdering treatment for 2-3 times repeatedly by using a powder machine, and performing high-temperature sterilization treatment; (2) performing ammoniation treatment, namely performing ammoniation treatment under a pressure condition of 0.3-0.4MPa; (3) performing magnetic fermentation, namely putting a mineral solution into a fermentation tank, and performing magnetic fermentation under conditions of vacuum degrees of 80%, 85% and 100% respectively; (4) performing enzymolysis, namely putting water into organic fermentation materials, adding mixed enzymes, and performing enzymolysis; (5) performing secondary fermentation, namely putting the mineral solution into the enzymolysis organic materials, adding fertilizer fermentation agents, and performing composting fermentation. Compared with a control group, the organic fertilizer prepared by using the method is capable of increasing the content of vitamin A in tomatoes by 32.6ug / 100g, increasing the ash content by 1.53%, and reducing the insect and disease rate by 1.79%.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer processing, and in particular relates to a method for preparing organic fertilizer for tomato planting. Background technique [0002] Tomato, Solanaceae Tomato is an annual or perennial herbaceous plant. Tomatoes are fleshy and juicy, with yellow seeds, rich nutrition and special flavor. Tomatoes are native to South America and are widely planted in southern and northern my country. Vegetables that are indispensable in daily life. Tomatoes are rich in lycopene, malic acid, citric acid and other ingredients, which have the functions of bactericidal and antibacterial, and promote digestion. They are also rich in nutrients such as vitamins, minerals, sugars, and cellulose, which can adjust gastrointestinal function, Lower cholesterol, with high nutritional and health value. However, the soil has been planted with tomatoes for a long time. Tomatoes with high nutrient content consume a lot ...

Problems solved by technology

[0003] The present invention is aimed at the existing problems: in terms of soil nutrition, the soil has been planted with tomatoes for a long time, and tomatoes with high nutrient content consume a lot of nutrients in the soil, and using chemical fertilizers to supplement nutrients will cause the soil to gradually harden and salinize. Tomato production has declined to a large extent, and the taste has declined
