Embodiment 1

[0027] A method for sexual reproduction of Gastrodia elata, comprising the following steps:

[0028] 1. Seed selection: select plump arrow hemp with a spindle shape, no pests, no mechanical damage, and a thick parrot beak;

[0029] 2. Pregermination: Take a 50cm×50cm×20cm wooden incubator soaked in a fungicide solution, spread 10-mesh fine sand with a thickness of 3-5cm on the bottom, and place 9 arrows in each box, keeping an interval of 10cm , the thickness of flat laying is 3cm fine sand, watering is uninterrupted during the germination period, the surface moisture content is maintained at 53%, and the germination temperature is controlled at 16°C;

[0030] 3. Artificial pollination: artificial self-pollination of arrowroot after germination, bolting and flowering;

[0031]4. The preparation of bacteria material: a, the preparation of Armillaria armillaria bacteria material: every year in the first ten days of March, the miscellaneous wood is cut into 25cm small sections, ...

Embodiment 2

[0042] A method for sexual reproduction of Gastrodia elata, characterized in that it comprises the following steps:

[0043] 1. Seed selection: select plump arrow hemp with a spindle shape, no pests, no mechanical damage, and a thick parrot beak;

[0044] 2. Pregermination: Take a 60cm×60cm×25cm wooden incubator soaked in a fungicide solution, spread mosses with a thickness of 3-5cm and a fineness of 20 mesh at the bottom, place 10 arrows in each box, and keep an interval of 13cm. Spread moss with a thickness of 3-5cm, sprinkle water continuously during germination, maintain the surface moisture content at 55%, and control the temperature at 20°C;

[0045] 3. Artificial pollination: artificially pollinate cross-pollination after sprouting and flowering of arrowroot;

[0046] 4. Preparation of bacterial material: a, preparation of Armillaria mellea bacterial material: Cut miscellaneous wood into 30cm segments in the first ten days of March every year, and each segment is divid...

Embodiment 3

[0057] 1. Seed selection: select plump arrow hemp with a spindle shape, no pests, no mechanical damage, and a thick parrot beak;

[0058] 2. Pregermination: Take a 70cm×70cm×30cm plastic incubator soaked in a fungicide solution, lay the bottom of the incubator with a fineness of 10 mesh and a thickness of 5cm sawdust, place 12 arrows in each box, keep an interval of 10cm, and spread finely. The density is 10 mesh wood chips, the thickness is 3-5cm thick, watering is uninterrupted during the germination period, the surface moisture content is maintained at 63%, and the temperature is controlled at 25°C;

[0059] 3. Artificial pollination: artificially pollinate and self-pollinate the arrowroot after germination, bolting and flowering;

[0060] 4. Preparation of bacterial materials: a, Armillaria bacterial material preparation: in the first ten days of March every year, miscellaneous trees are cut into small sections of 35 cm, and each section is divided into three sides and obl...

Abstract

The invention belongs to the technical field of agriculture, relates to a sexual reproduction technology of plants, and particularly relates to a sexual reproduction method of gastrodia elata. The method sequentially comprises the nine steps of seed selection, germination accelerating, artificial pollination, fungus material preparation, seed dressing, sowing, transplantation of fungus materials for culture, cultivation and harvesting. By means of the sexual reproduction method of the gastrodia elata, the problems that in the existing gastrodia elata planting process, genetic depression occurs, the germination rate is low, seeds are prone to microbial contamination, the zero-generation quality is low, and the product yield is low are solved. In the cultivation process of the gastrodia elata, the microbial contamination rate is low, the growth vigor of target fungi is good, the germination rate is high, the zero-generation quality is good, high and stable yield is achieved, and the product quality is good.

Description

technical field [0001] The invention belongs to the technical field of agriculture, relates to the technology of sexual reproduction of plants, in particular to a method for sexual reproduction of Gastrodia elata. Background technique [0002] Gastrodia elata (Gastrodiaelata B1.), also known as Chijian, is a perennial herbaceous plant belonging to Orchidaceae and Gastrodia elata. It is distributed in most parts of my country and is a commonly used precious Chinese medicinal material. Before the 1970s, commercial Gastrodia elata mainly relied on wild, With people's understanding of the nutritional value of Gastrodia elata, the market demand for Gastrodia elata is also increasing, and simply relying on wild resources can no longer meet people's needs. After the 1970s, through the efforts of scientists, the transformation of wild Gastrodia elata into home species was successful, and home-grown Gastrodia elata became the main commodity source. [0003] During the cultivation pro...
