Problems solved by technology

my country's farmers have also had the habit of eating corn smut tender tumors (commonly known as corn black rice, cob bag, corn black mold) for many years, but they have not seen it in my country's market. The main reason is that (1) there is no large-scale The production of corn mushrooms is limited to the sporadic corn mushrooms that are naturally morbid in the field, and the number is extremely small, and its utilization value is negligible; (2) the harvest quality of corn mushrooms has an important impact on sales, processing, and consumption
In most cases, corn mushrooms suitable for processing and eating cannot be harvested, which greatly affects the market acceptance of corn mushrooms

Embodiment 1

[0028] In this experiment, the isolation and cultivation of smut fungus was carried out in the headquarters of Jiangsu Academy of Agricultural Sciences, and the field inoculation was carried out in Liuhe Animal Science Base, including the following steps:

[0029] (1) Collection and cultivation of corn mushroom strains: Corn smut fungus was collected from Nanjing, Jiangsu, and a small amount of juice from the heart of the mycelium was picked up with a sterile needle under aseptic conditions and spread on PDA medium for 28 Cultivate for 5 days at ℃, transfer all the grown colonies to a 2 ml sterile centrifuge tube, add appropriate amount of sterile water to fully shake the suspended cells, and finally add glycerol to the suspension to make the concentration of glycerol 15%. Store in -80°C refrigerator for long-term storage.

[0030] PDA medium preparation method: 200 no potatoes, peeled and cut into small pieces, boiled in sterile water for 30 minutes, added 20 grams of sucrose...

Abstract

The present invention relates to a maize mushroom production method, and belongs to the technical field of mushroom cultivation. The method comprises: culturing ustilago maydis to prepare an inoculum solution with suitable concentration; after the susceptible maize hybrid tasseled, injecting the inoculum solution with suitable concentration through the filament passage into the top of corn cobs; and harvesting the maize mushroom in an adaptive period after inoculation. According to the maize mushroom produced by using the method provided by the present invention, the method has the advantages that the operation is simple, the yield is high, the appearance quality is good, and the batch production can be realized, and the method is a good method worth being promoted and applied.

Description

technical field [0001] The invention relates to a production method and products of corn mushrooms, which belong to the technical field of mushroom cultivation. Background technique [0002] Before the present invention is not disclosed, there has not been a method for artificial inoculation of large batches and high-yield production of corn mushrooms. [0003] Corn smut (Ustilago maydis) is the pathogenic bacterium of corn smut and belongs to the Basidiomycotina subphylum. The mycelium produced by heterothalism can infect all organs in the aboveground part of corn and produce tumor-like protrusions. The tumors formed after corn smut infect corn ears are shaped like mushrooms before they mature, which are called corn mushrooms. Corn mushrooms harvested at the right time taste sweet when eaten raw, and more flavorful when fried. Regular consumption of corn mushrooms can prevent and treat gastrointestinal ulcers and liver system diseases, and help digestion and laxative. Res...
