Embodiment 1

[0049] Present embodiment provides a kind of Gastrodia elata rejuvenation cultivation method, comprises the steps:

[0050] Seed hemp selection: In early November, after the underground tubers of Gastrodia elata stopped growing and before the soil was frozen, select the harvested arrow hemp with good appearance, body aspect ratio less than 3:2, full hemp tail, no disease and pest spots, The terminal buds are full and well-developed, and the arrow hemp with a single weight of 150-300 grams is used as a seed;

[0051] Control the dormancy of planting hemp: choose a bamboo frame with a length of 1 meter, a width of 40 cm, and a height of 40 cm, place straw with a thickness of 2 cm around the frame as a pad, and put the first layer of humus soil with a thickness of 10 cm at the bottom of the frame as a bottom , the water content of the humus soil should be grasped into a ball, let go and drop to disperse. Place the seed buds on the first layer of humus soil individually with the m...

Embodiment 2

[0062] Present embodiment provides a kind of Gastrodia elata rejuvenation cultivation method, comprises the steps:

[0063] Selection of hemp seeds: 10 days after the frost's descent (early November), after the underground tubers of Gastrodia elata stop growing and before the soil is frozen, select arrow hemp that has a good appearance, a body with an aspect ratio of less than 3:2, and plump tails. , no disease and insect spots, full and well-developed terminal buds, and arrow hemp with a single weight of 150-300 grams is used as seed;

[0064] Controlling hemp dormancy: choose a wooden frame with a length of 1 meter, a width of 40 cm, and a height of 40 cm, place straws with a thickness of 3 cm around the frame as a pad, and put the first layer of humus soil with a thickness of 12 cm at the bottom of the frame as a mat. At the bottom, the moisture content of the humus soil should be grasped into a ball, let go and drop to disperse. Place the seed buds individually on the firs...

Abstract

The invention relates to the technical field of gastrodia elata cultivation, in particular to a method for controlling dormancy of seed stem and a method for rejuvenating and cultivating gastrodia elata. According to the method for controlling the dormancy of the seed stem, disclosed by the invention, humus soil is adopted to coat the seed stem, namely arrow hemp and the arrow hemp is putted intoa breathable environment of 3 to 8 DEG C for treatment, so that the dormancy of the seed stem is prolonged. The seed nature of the gastrodia elata can be effectively restored by adopting the method tocarry out low temperature treatment on the seed stem. According to the rejuvenation cultivation technical method of the gastrodia elata, provided by the invention, steps such as seed stem dormancy, seed stem soaking, seed cultivation, seedbed preparation, sowing, management and harvesting are controlled, and several links are matched with one another, so that the winter chilling requirement of the seed stem is met and finally the seed stem restoring seed nature is obtained; the yield and the quality of finished gastrodia elata can be effectively improved by using the seed stem restoring the seed nature to plant and produce.

Description

technical field [0001] The invention relates to the technical field of Gastrodia elata cultivation, in particular to a method for controlling seed dormancy and a gastrodia elata rejuvenation cultivation method. Background technique [0002] Gastrodia elata is a saprophytic herb of the genus Gastrodia elata in the family Orchidaceae. The plant height can reach 2 meters, the tubers are oval to nearly dumbbell-shaped, and the capsules are obovate-elliptic. They are distributed in many areas of my country.
