The mother species should be cultivated early, the flower shape is normal, the mushroom cover is thick, the mushroom handle is short and fat, no pests and diseases, 7-8 cm mature mushrooms are placed in the inoculation box (sterile box) or inoculation room (the sterile room After scraping the epidermis with a razor blade, take a clean and sterile mushroom meat with about one mung bean and connect it to the above medium with an inoculation needle. The inoculated tubes were incubated in a 25-27° C. environment (incubator or incubator) and spherule-shaped white mycelium grew after 2-3 days of inoculation. (If there are green, black and other variegated bacteria or yeast-like substances in the test tube, it means that there are some bacteria, it should be eliminated.) About half a month after cultivation, the mycelium is covered with the surface of the Chinese cabbage, the mother Training will be successful. When used for isolation and inoculation, the tools used must be sterilized. The parent species is moved to a new medium and expanded cultures are generally referred to as "primary species". Used as a strain that is directly seeded into the wood, commonly known as cultivars.
2. Preparation of cultivars: At present, the strains used for artificial cultivation of mushrooms are mainly woody strains and species of wood strains.
(1) The medium formulation for the preparation of woody spore species is: 7.5 kg of various hard and dry wood chips suitable for the growth of shiitake mushrooms, 2.2 kg of rice bran or bran, 0.15 kg of sucrose, 0.15 kg of gypsum powder and 15 kg of water. According to the above proportions, mix wood chips and rice bran first, and dissolve sucrose and gypsum powder in 10 kg of water. Then pour the mixture into the above mixture and mix well. Then add the remaining 5 kg of water and mix it and mix it into the strainer bottle. Close to the bottle shoulder, slightly compacted (bottom slightly loose, slightly solid upper), and then use a pointed stick to drill a hole directly to the bottom of the bottle. Then put the cotton plug on the bottle, and use a kraft paper to tie up the cotton plug, move it to the steamer for another 4-6 hours (starting from the water, the fire should be fierce), or put it in a pressure cooker and maintain the pressure under 15 pounds. 1 hour for sterilization. After sterilization, remove and cool and use it for inoculation. The inoculation process should be performed under aseptic conditions. The inoculated needle should be used to pick up a small piece of the original stock that has been expanded and inoculated on the above-mentioned sawdust medium. After inoculation, it is placed in a 25-27°C environment for about one month. (or 20-25 °C culture 1-2 months), after the mycelium full bottle, you can inoculated to Duanmu up.
(2) Preparation of seed strains: The seed strains of shiitake mushrooms are mainly triangular wood and round wood. Triangle wood is made of wood suitable for growing shiitake mushrooms into wood strips 0.8 centimeters thick and 1 centimeter wide, and then processed into triangular wood blocks (specifications: thickness 0.8 centimeters, width 1 centimeter, height 1-1.5 centimeters). The logs were first sawed wood into 1.2 cm wood chips, and washed down with belts one by one. The processed triangular wood or logs should be dried immediately. To make a 10 kg dry seeding medium, add 2 kg wood chips, 1 kg rice bran (or bran), 0.1 kg sucrose, 0.1 kg gypsum powder, and 4.5 kg water. Soak the dry seed wood in the 1% sugar solution for 12-24 hours or in the pot and boil it for 15-20 minutes. Remove the wood and mix with three-quarters of the mixture. The bottle (or other bottle), with the remaining quarter cover, mounted to the shoulder, slightly compacted, flattened, stuffed with cotton plugs, the disinfection of bacteria and culture methods and woody species. After a period of cultivation, it becomes a triangular or roundwood species.
Inoculation and cultivation of Duanmu
1. The choice of mushroom farm should be considered from the aspects of temperature, humidity, light, ventilation, etc. It is best to choose a gentle slope or open land facing south from south to south. It is required to be close to the water source, well drained, and the ground is dry. The soil contains more acidic sand containing gravel. The soil is suitable. There should be a tall shade tree or shading shed above it. The gutter should be opened around the mushroom field. There are about 200 species of shiitake mushrooms that can grow in China. Fagaceae and birch families are ideal species. Maple, oak and birch trees can also be used as tree species. After cutting down the mushrooms to allow them to dry naturally, they are usually dried to a moderate extent when there are several short cracks in the tree heart, and then sawn into a section of wood to inoculate.
2. Artificial inoculation can be carried out from December to March of the following year. It is most suitable from January to April. Before the inoculation, mushroom twigs should be removed, the logs should be sawn into a one-meter-long section of wood, and 1% lime water should be used to disinfect the fractures.
Inoculation method:
(1) punch holes with a belt, the hole must be at least 1 cm deep wood, the general spacing of 20-30 cm, spacing 6-10 cm.
(2) Put the bacteria into the hole and press it slightly with your finger.
(3) Put the bark cover (slightly larger than the hole) prepared in advance on the hole cover, and tap it with a hammer to make it tightly plug the hole. The bacterial strain should be used on the same day as the bottle was opened on the same day. It will not be contaminated with bacteria. Mushrooms after inoculation in winter should be stacked tightly on the leeward warm place of the mushroom farm, surrounded by nylon paper, and covered with branches. The nylon paper should be tilted every three to five days to make air change. After 20 days, white hyphae grew on the edge of the inoculation hole, indicating that the hyphae had colonized successfully. The germination period lasts for about 1-1.5 months.
3, mushroom period includes spring, summer and autumn three seasons. In spring and summer, it focuses on rain and sun protection. It mainly focuses on the stacking, turning, and shading of sections of wood. It usually takes 2-3 months to turn it over once. If it is long and rainy, turn it immediately after it is clear. Throughout the culture period, the sun must not be allowed to be direct, but there must be some scattered light. Natural trees are often shaded by tall trees or covered with branches, bark, and other coverings, and can also be shaded. In autumn, the management of mushrooms and mushrooms is based on insulation, and the surface layer can be properly dried to promote the growth of mycelium to the deep layer and expand the nutritional range of the bacteria. Before and after the frost, strengthen the management of the mushrooming period. When the average temperature drops to around 15°C on that day, the mature mushrooms will be moved out of the mushroom farm in the autumn, and the trees will be re-arranged to make up the water. Mushrooms after watering, in case of low temperatures below 10°C, should be stacked in a sunny place, covered with nylon paper or straw mats, until a large number of mushroom buds grow, then scattered piles of wood.
After the mushroom is harvested, the wood is to be returned to the farm for stacking, managed according to the conventional method of cultivating bacteria, and special attention shall be paid to the control of pests and diseases, moisture, and sun protection, so that the mushroom mycelia will continue to grow, so that the normal mushroom production will occur again in the coming year.
Mushrooms usually grow to maturity in the seven or eight mushrooms, forming the edge of copper. That is timely picking. Pick mushrooms should be selected to be sunny, the entire mushroom root picking, and drying in time drying. The dried degree of commercial mushroom must reach about 18% of water content for long-term preservation. At present, firepower is used for drying, and half-baking and half-baking methods are also used.
1, the parent species culture: mushrooms "mother species" refers to the use of mushroom spores, tissue (mushroom meat) or mushrooms isolated cultured strains. Cultivation of shiitake mushroom parent, potato and seaweed culture medium. The culture medium was formulated as follows: 200 g of peeled potato (or sweet potato), 20 g of glucose (or sucrose), 20 g of agar and 1 kg of water. According to the above proportions, the peeled potatoes are washed and shredded, and then put into a pot and boiled for 20-30 minutes in proper amount. The slag is filtered with several layers of gauze, the filtrate is added with water to a sufficient amount, and then the agar and glucose are added. Heat it to melt it. Then heat the test tube and place it in a test tube. Put the cotton on the tube and bundle it into bundles. Wrap the paper in kraft paper, place it in a pressure cooker, maintain it under a pressure of 15 pounds for 30 minutes, or steam it 2-3 times in a steamer ( Once a day, one hour at a time, it can also achieve the purpose of sterilization. Place the sterilized test tubes on the table and wait until they are solidified.
