High-yielding Cultivation Technique of Agrocybe aegerita

The champignon mushroom body is thick, the stipe is crisp and delicious, and it is rich in nutrients. It contains eight kinds of amino acids necessary for the human body, including high levels of lysine, arginine, and glutamic acid, and also has a certain medicinal value. High-yield cultivation should master the following key technologies.

The seedlings of the fine strains of fine strains were selected to be white, thick, thick, vigorous and uniform. Where bacteria, yellow, green, black, orange, and other colors are found in the bacterial infection, such bacteria should be banned.

Choose the optimum cultivation period Agrocybe aegerita fruiting temperature is 16 °C ~ 30 °C, generally inoculated in March, all over the country can also choose according to local climatic conditions suitable time cultivation.

The formulation of raw materials for production of Agrocybe aegerita cultivars is: 50% cottonseed husk, 26% wood chips, 15% bran, 5% corn flour, 2% gypsum, 1% phosphate fertilizer, 1% lime, can also be added to the formula 1 ~3% of tea seed cake or tea seed shell, this can improve the aroma of Agrocybe. After selecting the formula, the following three points should be noted when making the ingredients: First, the cottonseed husk, bran, etc. should be fresh, such as moldy or agglomerate can not be used. Sawdust is more than half a year old, loose texture of broad-leaved wood chips is better. The second is to mix the ingredients evenly, to achieve "three uniforms" (that is, uniform material, uniform water, uniform pH). The third is to mix the good material, should check the moisture content of the culture material, so that it reaches 60% to 65%;

Bag planting requirements generally use 15 cm 30 cm or 17 cm 33 cm polypropylene plastic bag cultivation, each bag of dry material 0.3 ~ 0.35 kg. Put the material into the bag and put it on the collar and cover it with a sponge cover.

Sterilization of thoroughly sterilized cultivating materials is classified into normal pressure sterilization and tube pressure sterilization. Atmospheric sterilization is maintained at 100°C for 14 hours; autoclaving is maintained at 1.5 kg/cm2 for 2 hours. Disinfection and sterilization must be thorough, otherwise serious contamination of bacteria, will result in reduced production or even no income.

After sterilizing the inoculum culture cultivating material, the temperature of the material can be vaccinated to about 30°C. Inoculation should be carried out in the inoculation box. When inoculating, the following points should be made: First, after the cultivation materials are placed in the inoculation box, formaldehyde and potassium permanganate are used for fumigation to disinfect the space. The dosage is 10 ml of formaldehyde and 7 g of potassium permanganate per cubic meter of space. The mixture was inoculated after 30 minutes of mixing and fumigation. Second, the vaccinator's hands and inoculation tools must be wiped with 75% alcohol. The inoculation should be performed above the flame of the alcohol lamp and the action should be quick. The third is to increase the amount of inoculation when inoculated, is conducive to the germination of mycelium. The cultivation is carried out indoors. The arrangement of cultivation materials includes single-layer upright discharge and wall discharge. After the row is finished, it is best to sprinkle some lime powder on the lid to reduce the pollution. The culture room should be ventilated, keep the temperature at 23 °C ~ 28 °C, and it is best to shading. After 50 to 60 days of cultivation, the hyphae can grow to the bottom of the bag.

Mushroom management When the mycelium is full of bags, the collar can be removed, the mouth of the bag can be straightened, and the old bacteria can be excavated. The sheds can be shaded either indoors or outdoors. Fungus bags can also be wall-stacked or single-storey erected at fruiting plants. After a good row of scattered light to maintain a certain, spray water 1 to 2 times a day, so that the air humidity of 86% to 95%, spray water depending on the weather may be, sunny and more spray, cloudy days spray, rain can not spray. At the same time pay attention to ventilation, so as not to produce abnormal mushroom.

Timely harvesting is managed by 15 to 20 days, and fruit body growth can be harvested when it reaches 80% maturity. When harvesting, it is best to harvest once in the morning and in the afternoon in order to make the mushroom shape and quality of the mushroom. After harvesting, the fungus bag should be stopped for 5 to 10 days, and then continue to spray water management. Later, a second batch of mushrooms will be produced. Generally 3 to 4 batches of mushrooms can be harvested.

Fish Snacks are ready to eat in a bag. They are delicious. In life, they are a kind of snacks that people often eat. They are diverse and rich in nutrients.Yellow croaker snacks are made from yellow croaker fish. There are two kinds of yellow croaker. One is rhubarb croaker. The meat is thick, but the bone spurs are more, while the smaller ones are small yellow croaker. The meat is tender and the bone spurs are small. Two kinds of yellow croaker can be made into yellow fish snacks, but relatively speaking, small yellow croaker snacks have a good taste, soft and easy to chew, even those with bad mouth can eat, of course, everyone's taste is not the same, Choose what you like. The croaker meat is rich in protein, vitamins and trace element selenium. It is also beneficial to the body to eat yellow croaker snacks.
