Tianma sexual reproduction and cultivation techniques
I. Planting season and planting method The mature period of the gastrodia seeds is the planting period, which is generally from June to July. Taking indoor planting as an example, clean the interior first and spray 5-10% of carbendazim around the floor and walls. If it is a concrete floor and the drainage is poor, a layer of 10cm thick pebbles should be laid. . Sexual reproduction usually consists of a bottle of germination bacteria per hole, a bottle of honey fungus, and 8 to 10 gastrodia fruit. Among them, Armillaria are mostly phloem bacteria, which are called fungal shoots; germinating bacteria are mostly phyllosporins, which are called bacilli. The planting hole is 50 cm long, 50 cm wide and 40 cm deep. When planting, first put the germinating bacteria into a clean pot, use scissors to cut the leaf bacterium to the size of the fingernail, squeeze the gastrodia fruit by hand, and gently sprinkle the powdery seeds in the fruit on the leaf. Scatter and turn constantly to mix the seeds and leaves. Divide the seeded leaf bacterium into two equal portions, then pour the armillaria into another clean pot and divide it into two. When planting, plant on the wall, lay a layer of 10cm sand mixed wood chips on the bottom layer, then spread a layer of 2cm thick soaked leaves on the sand, then mix the seed germination bacteria Spread evenly on the leaves. Place a piece of Armillaria spp. in parallel and put one on each side. Place as close to the cut as possible. Sprinkle the other half of the spores in the gaps of the wood, fill the gaps with sand, fill in the wood, and reseeding the second layer in the same way. After sowing, cover with 10 cm thick sand, and finally cover with a straw with a thickness of 3 cm. Use the same method and then plant the second hole, the second hole can be spaced 10 cm, filled with sand in the middle. Second, management after sowing Adjust the temperature: Appropriate germination temperature for the seeds of Gastrodia elata is 22°C～25°C. If the temperature is low at the initial stage of sowing, cover plastic film or rice straw to increase the temperature. In July-August, when the temperature is high, take a shade shed or sprinkle water around to cool down. 2. Control Humidity: Always plant the sand and keep it moist. Sprinkle water in a timely manner so that it can be sprinkled, sprinkled, and dried. In short, the growth period for sexual reproduction is one and a half years, ie, planting from June to July of that year, and harvesting at the end of the second year. Of these, 30% of the finished gastrodia can be sold directly, and the remaining generation can directly reproduce asexually. China Agricultural Network Editor
