1 Bed frame setting: The bed frame is the same as the one used for growing mushrooms. The frame is generally 1.2 meters wide, 2.5 to 3 meters high and 5.5 meters long. The bottom layer can be cultivated on the ground, using a pit type double-leafing method. Each frame of the bed frame is 60 cm apart and can be planted with 5 to 6 layers. Use iron frame or wood poles can be used, as long as it is sturdy and durable. The bottom of each shelf is made of wood, board (preferably not pine pine boards, if you can not find hardwood broad-leaved trees, pine pine boards can also be used instead), wide strips, etc. can be. If there are no planks, it is also possible to use a bamboo raft as a bed base, but it must be laid densely or a layer of plastic film (with some holes) be placed on the raft to prevent leakage of the culture material. Surrounded by planks or straw curtains, the groove is 30 cm high. Sulfur dioxide sterilized by sulphur burning in the room before hemp. Close doors and windows in advance, and use 1 to 1.5 kg of sulphur per 100 cubic meters; or 100 to 150 grams of sulphur, 50 milliliters of dichlorvos and formalin (also known as formaldehyde), blend with appropriate amount of sawdust; or use Formalar. 500 ml forest, then add 20% potassium permanganate fumigation, smoke 24 hours and then release the residual gas; 2 Planting time: The cultivation of gastrodin on the bed frame can start from October to November, but the room must have heating equipment. It is better to use coal gangue as fuel, use closed furnace to heat, add coal once every 24 hours or 36 hours. It is labor-saving and low-cost, and it can maintain the indoor temperature; it can also be cultivated in the second year of February, but the cultivation yield is high from October to November. After indoor poisoning, it should be immediately planted. The bottom of the underground pit digging. A plastic film is punched in the slot in the bed frame. The length of the bacteria stick is 1.1 meters, or it can be connected with two 55-cm long rods. The specific planting method can refer to the outdoor flat stubble planting method or the box planting double layer stubble method. 3 temperature and humidity management: cultivation of Gastrodia in autumn and winter, the beginning of the indoor temperature is low, maintained at 1 ~ 5 °C for 50 days. Allow Tianma to sleep. After the dormancy period has passed, the temperature in the room should be gradually increased. When the temperature in the culture material rises to 8°C, Armillariella begins to grow. At a temperature of 12°C, Gastrodia begins to germinate, and at the same time Gastrodia elata is easily attached to Gastrodia elata. When the temperature rises to 15 to 20°C, the humidity should reach 55% to 60%; when the temperature rises to 20 to 25°C, the humidity should increase to 65%. The temperature is between 20 and 25°C and it is the growth of Gastrodia and Armillaria. The longer the temperature is constant at 20 to 25°C, the easier it is to obtain high yields. However, the temperature must not exceed 25°C and the humidity must not exceed 70%. The room temperature should be constant, do not flicker, in order to prevent causing burnt. After September, Gastrodia elata grows slowly as the temperature decreases, and the humidity should also decrease. Watering can no longer be done. By the beginning of October, the moisture content of the culture materials should be reduced to 30% to 40%. (Excessive humidity can easily cause numbing), and from the middle of October to the beginning of November, it can be used as a hemp. Indoors should be kept clean and hygienic to prevent the spread of bacteria, but also to prevent and control the harm of rats.
