Characteristics and Cultural Techniques of Hybrid Tianma "Yihongyou 1"

The "Guihongyou No. 1" Hybrid Tianma was selected as the male parent of wild red gastrodia at high elevations. It was selected as a female parent of fine red gastrodia in the artificial indoor box of Jianghan Plain. The hybrid cross-pollination is robust, and the hybrid is suitable for both indoor cultivation in low-altitude plain areas and outdoor hybrid imitation of wild cultivation of high altitude 500-1800 m in hilly areas. It fills the gaps in the cultivation of hybrids that have no sexual hybrids in the mountains, hills, and especially in the plains of China.

1. Characteristic characteristics: "Yihongyou No. 1" hybrid gastrodia has been distributed to Sichuan, Chongqing, Yunnan, Guizhou, Xinjiang, Gansu, Shaanxi, Henan, Shandong, Hebei, Tianjin, Jilin, Heilongjiang, Hainan, Fujian, Zhejiang and Jiangxi for the past 5 years. , Guangxi, Anhui, Hunan and other provinces and cities to promote cultivation and Yichang Three Gorges Tianmu base outdoor imitation wild cultivation and Hubei Jianghan Plain indoor planting 1 million boxes (bags) confirmed that its good commercial, individual round and full, generally fresh 200 ~ 500 grams, high quality. In particular, the breeding power is very strong, the propagation coefficient is large, and the yield is more than 30% higher than the irreducible conventional varieties. The optimum growth temperature is 14-28°C, the optimum temperature is 20-25°C, and the total accumulated temperature during the growth period is about 3800°C.

2. Cultivation points: In the mountainous area, the outdoor rammed cover soil is used to imitate wild cultivation, and associated with the “Yifeng No. 4” branch honey ring mushroom species, 500 g per square meter sowing can produce fresh gastrodia 10-15 kilograms; plain indoor box type Soilless sand cultivation, each box (505035 cm) broadcast hemp seeds 150 to 200 grams, can produce fresh gastrodia 4 to 5 kg; indoor bag planted (4035 cm) broadcast hemp seeds 100 to 120 grams, can produce fresh gastrodia 1.5 to 2 kg.

3. Harvesting: Outdoor winter planting (November to January), digging 10-12 months after planting, spring planting (March to May), excavation 7-8 months after sowing, indoor box (bags ) Cultivation, artificial regulation of temperature around 20 °C, 6 months can be harvested, 1 year can be cultivated 2 periods.
