Abstract

The invention provides a method for increasing the seed germination rate in a sexual-propagation breeding process of rhizoma gastrodiae. The method comprises the following steps: culturing an armillaria mellea material through a conventional method in July last year; culturing sawdust medium germination fungus plastic bag strains through the conventional method in November last year; selecting rhizoma gastrodiae without diseases and insect pests in November last year and preserving the rhizoma gastrodiae under the natural air temperature condition; germinating and artificially pollinating thepreserved rhizoma gastrodiae through the conventional method in the first ten days of January of next year, and picking rhizoma gastrodiae capsules in the last ten days of March; breaking the plasticbag strains into small blocks with size of 2cm by hands; breaking the rhizoma gastrodiae capsules and taking seeds, and mixing the seeds with the small blocks; putting the small blocks in breeding bags, sealing the breeding bags by reserving ventilation small holes in the breeding bags, and culturing for 4-7 days; opening the bags with the cultured germination fungus blocks, mixing the cultured germination fungus blocks with fine sand, then filling the germination fungus blocks in the breeding bags, culturing for 20 days by keeping the breeding bags in open state, and planting the germinationfungus blocks in fields when dark brown fungus films are formed on the surfaces of the germination fungus blocks. The cultured germination fungus small blocks mixed with the rhizoma gastrodiae seeds have the effects of resisting drought and resisting moisture; the loss caused by blight and rot of the strains can be reduced; the seed germination rate can be increased.

Description

technical field [0001] The invention relates to a method for sexual reproduction and breeding of gastrodia elata, in particular to a method for increasing the germination rate of seeds in the process of sexual reproduction and breeding of gastrodia elata. Background technique [0002] The seeds of Gastrodia elata are extremely small, like powder, without endosperm and other nutrients, and cannot germinate by themselves. They need to provide nutrients for Gastrodia elata seeds to germinate after being infected by germination bacteria. Because the Gastrodia elata seeds are extremely small and are not resistant to storage, the planting method that the Gastrodia elata seeds are picked, mixed with germination bacteria and then dropped into the field is adopted at present. This planting method has the phenomenon that the germination bacteria mixed with the gastrodia elata seeds are easy to wither and rot, resulting in a low germination rate of the gastrodia elata seeds.
