Cultivation techniques of sexual Propagation of Gastrodia elata

I. planting season and planting methods

The mature period of Gastrodia elata seeds is the planting period, usually from June to July. Take indoor planting as an example, first clean the room and spray the ground and walls with 5% to 10% carbendazim. If it is a cement floor with poor drainage, lay a layer of pebbles 10 cm thick.

Sexual reproduction is generally a bottle of germinating bacteria, a bottle of Armillaria mellea, 8 to 10 Gastrodia elata fruits per hole. Among them, Armillaria mellea is mostly branch bacteria, called branches, and germinating bacteria are mostly leaf fungi, called leaves. The specification of the planting hole is 50 cm long, 50 cm wide and 40 cm deep.

When planting, first pour the germinating bacteria into a clean basin, cut the leaf fungus to the size of a fingernail with scissors, pinch open the Gastrodia elata fruit with your hands, gently sprinkle the powdery seeds in the fruit on the fungus leaves, spread them evenly as far as possible, and constantly turn them to mix the seeds and leaves evenly. Divide the leaf fungus mixed with seeds into two equal parts, then pour the branches of Armillaria mellea into another clean basin, and divide them into two parts.

When planting against the wall, you should first spread a layer of 10cm sand mixed with sawdust on the bottom layer, then spread a layer of soaked leaves 2cm thick on top of the sand, and then spread the equal portion of the germinating bacteria mixed with seeds evenly on the leaves. Put a section of Armillaria mellea in parallel, one at each end, and keep it close to the cut as close as possible. Scatter the other half of the fungus in the gap of the wood, fill the gap with sand, fill it until the wood is slightly exposed, and sow the second layer in the same way. After sowing, cover 10 cm thick sand, and finally cover 3 cm thick straw and other mulch. Use the same method to plant the second hole, which can be separated by 10 cm and filled with sand in the middle.

2. Management after sowing

1. Adjusting temperature: the suitable germination temperature of Gastrodia elata seeds is 22-25 ℃. If the initial temperature of sowing is low, plastic film or rice straw should be added to increase the ground temperature. When the temperature is high from July to August, it is necessary to build a shade shed or sprinkle water around to cool down.

two。 Control humidity: the sand planted should always be kept moist and sprinkled in time, so as to sprinkle frequently and less, and would rather be dry than waterlogged.

In short, the growth period of sexual reproduction is one and a half years, that is, it is planted from June to July of that year, and harvested at the end of the second year. 30% of the finished Gastrodia elata can be sold directly, and the rest of the next generation can be reproduced directly.
