Embodiment 1

[0042] A high-quality and high-yield seed production method of Rhododendron elata, said method comprising the following steps:

[0043] S1: The mycelium of the fungus wraps the Gastrodia gastrodia sativa excavated in November-December of the first year and January of the second year;

[0044] S2: Preserve at 2-5°C, place in mid-June of the second year at 20-25°C for bolting, flowering, pollination, and result in Gastrodia elata capsules;

[0045] S3: S2 red Gastrodia elata capsules are sown and managed from late July to mid-August to allow the seeds to germinate into protocorms or rice hemp.

[0046] Preferably, the fungal mycelium in the step S1 is Trametes grandis, Osmanthus edulis, Dendrobium, Oyster mushroom, Lentinus edodes, Poria cocos, Black fungus, Pleurotus eryngii, Stropharia, Hericium erinaceus or mushroom Fungal mycelium.

[0047] Further preferably, the culture medium used in the step S1 fungal mycelium culture includes the following components in parts by weigh...

Embodiment 2

[0057] Adopt the method of embodiment 1, cultivate black-red hybrid Gastrodia elata, the contriver adopts this method to cultivate Gastrodia elata fruit in Hainan Island in October, see figure 1 ; figure 2 ; image 3 . It shows that "the growth and development cycle of Gastrodia elata from arrowhead-bolting-flowering-seed-white hemp can be regulated and fixed at any time or season. It is not only of great theoretical significance in breeding, but also more important in production practice. Innovative and practical.

Embodiment 3

[0059] Using the method of Example 1, on July 25, 2017, at an altitude of 1,700 meters (Wenjiaping, Changyang County), the seeds of Gastrodia elata were cultivated by this method, and they were excavated in November 2018. The yield per square meter reached 7.6kg , 1kg is priced at 90 yuan, much higher than the market price. Gastrodia elata in kind Figure 4 , Figure 5 . Figure 4 After sowing the small white hemp at the bottom of the cigarette butt, only 150g of arrowhead can be harvested, and after the bottom seed—big white hemp is sown, 450-500g of arrowhead can be harvested. Figure 5 Upper middle—large white hemp species; middle—middle white hemp species; lower—small white hemp species.

Abstract

The invention relates to a high-quality and high-yield seed production method of Gastrodia elata. The method is that the mycelium of the fungus wraps the Gastrodia gastrodia and arrowhead excavated in November-December of the first year and January of the second year; Preserve at 2-5°C, place in mid-June of the second year at 20-25°C for bolting, flowering, pollination, and results in red gastrodia elata capsules; red gastrodia elata capsules are sown from late July to mid-August, and the seeds are allowed to grow. Germinate into protocorms or rice hemp. The hemp seeds cultivated by the invention are all medium and large white hemp seeds, or extra-grade high-quality white hemp seeds. Using this kind of hemp to cultivate red gastrodia commercial hemp has high quality, high yield and stable yield. It makes full use of or saves limited and precious wood resources, and has remarkable ecological, economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of Gastrodia elata planting, in particular to a high-quality and high-yield seed production method of Gastrodia elata. Background technique [0002] Red gastrodia elata (G.elata.Blf.elata) and black gastrodia elata (G.elata.Bl f. glaucdS.chow) are the two "dominant varieties" with the longest cultivation history and the largest cultivation area in my country. Gastrodia elata is naturally distributed in the southwest Yunnan-Guizhou Plateau and the northeast region, and is limited to high mountains above 1500 meters in the Yangtze River Basin. Production and sales only account for 20% of the market share. More than 80% of production and sales are red gastrodia. Red gastrodia elata is widely distributed in mountainous areas at an altitude of 700-1500 meters. Compared with Gastrodia elata, it has high yield and strong meristem, but its quality is poor. One is hemp-shaped long strips, not thick. The second i...
