How do Gastrodia elata cultivation methods affect Gastrodia elata yield?

Choosing good planting methods for the tubers is also one of the important measures for increasing Gastrodia elata yield. Box cultivation and pit cultivation of Gastrodia elata overwintered in double-layer plastic sheds can significantly increase yield. Because the double-layer plastic shed uses sunlight as its energy source, it greatly increases Gastrodia elata yield. According to trials by the Institute of Special Animal and Plant Sciences of the Chinese Academy of Agricultural Sciences, using a double-layer plastic shed to overwinter box-cultivated Gastrodia elata inside the shed, Shaanxi seed stock increased in weight by 27.4 times, and local Jilin seed stock increased in weight by 99.8 times.

If there is heating equipment indoors, using wide-mouth bottles and plastic bags to cultivate Gastrodia elata and placing them on bed frames can greatly increase yield. Each bottle can produce 60-100 grams of fresh Gastrodia elata, and each sq m can produce 15-25 kg of fresh tubers. The yield from plastic bag cultivation is even higher than that from bottle cultivation.

Propagating Gastrodia elata by sexual reproduction is the most important measure for increasing Gastrodia elata yield, because the number of seeds in a capsule is extremely large, reaching 40,000-60,000 seeds in one capsule, and sexual reproduction is tens of thousands of times or even several tens of thousands of times greater than asexual reproduction.
