Embodiment 1

[0028] An organic microbial fertilizer for lettuce, its raw materials include the following components by weight: 4-7 parts of Streptomyces aureus, 0.6-0.9 parts of Bacillus thuringiensis, 3-5 parts of enzyme bacteria, 900-1100 parts of waste liquid sediment, inorganic 240-380 parts of fertilizer, 45-55 parts of trace elements, 25-32 parts of adhesive, 0.5-0.7 parts of stabilizer, 0.1-0.3 parts of stabilizing agent, 55-60 parts of sapindus seed coat, holly hair 5-15 parts, 1-15 parts of Daphne chamaejasme, 5-10 parts of hops, 25-30 parts of pepper, 25-30 parts of ginkgo seed coat, 26-30 parts of cnidium, 17-30 parts of neem bark, 16 parts of Shi Junzi -25 parts, gallnut 1-15 parts, matrine 5-10 parts.

[0029] The waste liquid sediment comes from the production process of amino acids such as monosodium glutamate factory and lysine factory.

[0030] The inorganic fertilizer urea, ammonium dihydrogen phosphate and potassium sulfate are mixed in a weight ratio of 4-6:3-5:1-2.

Abstract

The invention discloses an organic microbial fertilizer for lettuces and a preparation method thereof. The organic microbial fertilizer for lettuces is prepared from the following components in parts by weight: 4-7 parts of streptomyces aureus, 0.6-0.9 part of bacillus thuringiensis, 3-5 parts of enzyme bacteria, 900-1100 parts of waste liquid precipitates, 240-380 parts of an inorganic fertilizer, 45-55 parts of trace elements, 25-32 parts of an adhesive, 0.5-0.7 part of a stabilizer and 0.1-0.3 part of an effect-stabilizer assistant. The organic microbial fertilizer prepared by the method is capable of increasing the yield of the lettuce, the content of vitamin C and the content of an iron element; and the content of nitrate is reduced, so that the quality of the lettuce is enhanced greatly. Compared with other fertilizers containing the same nutrients, the organic microbial fertilizer is capable of decreasing or lowering crop disease-pest damages which affect the crop quality. The using quantity of a chemical fertilizer is not decreased, and the organic microbial fertilizer is beneficial to environmental protection.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a lettuce organic microbial fertilizer and a preparation method thereof. Background technique [0002] Lettuce is a vegetable that people often eat, especially in summer, lettuce is deeply loved by people; however, there are many diseases in lettuce during the growth period, among which rot is an important factor affecting its yield and quality; lettuce rot is also known as Pseudomonas rot or bacterial leaf spot of lettuce is a bacterial disease. At the time of onset, the leaf margins are water-soaked at first, and gradually turn from light brown to dark green, part of the mesophyll tissue is dead, and the leaves are shrunken. During the bulbing stage, light brown water-soaked lesions appeared on the midrib or edge of the outer leaf, and soon after, the veins turned brown and expanded rapidly, but there was no mold layer. The inner leaves are browned and soft rotted, and the surface of...
