Microorganism fertilizer for preventing and treating valsa mali of lettuce and preparation method thereof

Abstract

The invention discloses a microorganism fertilizer for preventing and treating valsa mali of lettuce and a preparation method thereof. The microorganism fertilizer for preventing and treating the valsa mali of lettuce comprises 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 microorganism, 900-1,100 parts of waste liquid precipitate, 240-380 parts of inorganic fertilizer, 45-55 parts of trace element, 25-32 parts of adhesive, 0.5-0.7 part of stabilizing agent, 0.1-0.3 part of stabilizing effect additive and 24-36 parts of insecticide. According to the method, the waste liquid precipitates produced in an amino acid production process are fully used and are fermented by yeast fungus; the prepared microorganism fertilizer for preventing and treating the valsa mali of the lettuce can greatly reduce the valsa mali morbidity of the lettuce, and the yield of gingers is increased; plants vigorously grow; the quality is also improved; the insecticide component is also added, so that the aphid disease in the growth process is also greatly reduced.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a microbial fertilizer for preventing and treating lettuce rot 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 ro...
