Problems solved by technology

The traditional germination medium with leaves as the main raw material, because the leaves are too thin, lacks nutrition itself, and after sowing, the nutrition of the leaves is quickly exhausted due to the absorption of germination bacteria, and the Gastrodia elata seeds are short of nutrition when they germinate. As a result, 80-90% of the protocorms die prematurely due to lack of nutrition, leading to a large waste of germination strains, increasing input, but the output is very limited, and the production of leaf germination bacteria is labor-intensive and time-consuming, wasting manpower , Huge physical resources

example 1

[0013] Example 1: Take 70% dry Aoki fruit by weight, 15% wheat bran, 13% sawdust, 1% sugar, and 1% starch. Stir all raw materials and dry materials evenly, then add 60 kg of water to every 100 kg of dry materials, stir again, then put them into a high-temperature and high-pressure polyethylene strain bag with a diameter of 14 cm, and sterilize at high temperature for 18-20 hours. Then take out and inoculate the original seed of the germinating bacteria Dendrobium small mushroom in the inoculation box, and after about 60 days the strain is full of bags, it can be used for sowing Gastrodia elata seeds.

[0014] When sowing, tear the germinated fungus bag, pour out the fungus, and rub it with your hands, the fungus will become granulated by itself, and you can sow it by mixing it with Gastrodia elata seeds.

example 2

[0015] Example 2: Take by weight 75% of the dried Aoki fruit, 12% of wheat bran, 10% of sawdust, 1.5% of sugar, and 1.5% of starch. Stir all raw materials and dry materials evenly, then add 65 kg of water to every 100 kg of dry materials, stir again, then put them into a high-temperature and high-pressure polyethylene strainer bag with a diameter of 14 cm, and sterilize at high temperature for 18-20 hours. Then take out and inoculate the original seed of the germinating bacteria Dendrobium small mushroom in the inoculation box, and after about 60 days the strain is full of bags, it can be used for sowing Gastrodia elata seeds.

[0016] When sowing, tear the germinated fungus bag, pour out the fungus, and rub it with your hands, the fungus will become granulated by itself, and you can sow it by mixing it with Gastrodia elata seeds.

example 3

[0017] Example 3: Take 65% of dry Aoki fruit by weight, 15% of wheat bran, 16% of sawdust, 1% of sugar, and 3% of starch. Stir all the dry raw materials evenly, then add 58 kg of water for every 100 kg of dry materials and stir again, then put them into a high-temperature and high-pressure polyethylene strainer bag with a diameter of 14 cm, and sterilize at high temperature for 18-20 hours. Then take out and inoculate the original seed of the germinating bacteria Dendrobium small mushroom in the inoculation box, and after about 60 days the strain is full of bags, it can be used for sowing Gastrodia elata seeds.

[0018] When sowing, tear the germinated fungus bag, pour out the fungus, and rub it with your hands, the fungus will become granulated by itself, and you can sow it by mixing it with Gastrodia elata seeds.

[0019] practice shows that:

[0020] Because the fruit of Qingmushu is relatively thick, rich in nutrition and uniform in grain size, there are as many as 1,250 ...

Abstract

The invention relates to a culture medium for tall gastrodia tuber germination strains. The culture medium is characterized by being prepared from the following raw materials in percentage by weight: 60 to 80 percent of dried aucuba japonica fruits, 10 to 20 percent of wheat bran, 5 to 20 percent of saw dust, 0.8 to 3 percent of sugar and 0.8 to 3 percent of starch. The aucuba japonica fruits have abundant nutrition, are large and plump and store more nutriments, and the effective support time can reach over 130 days, so tall gastrodia tuber protocorm on granular strains has vigorous vitalityand is thick and strong and strives for more time for halimasch inoculation of a large number of tall gastrodia tuber seeds; therefore, the yield of the generative propagation of tall gastrodia tuberis improved substantially. In addition, the aucuba japonica fruits are consistent in size basically and are elastic, have more porous structures and multilayer tissues and are favorable for the ingestion of ingredients and nutrition. The inoculation rate of the granular germination strains of the aucuba japonica fruits can reach 12 to 13.5 percent.

Description

1. Technical field [0001] The invention relates to a technique for artificially cultivating Gastrodia elata, in particular to a medium for germination strains of Gastrodia elata. 2. Background technology [0002] After the seeds of Gastrodia elata mature, they must use the nutrients provided by the symbiotic germination bacteria to make the seeds germinate into protocorms. After the protocorms are connected to the fungus, they absorb the nutrients provided by the fungus, and the seeds of Gastrodia elata can form rice hemp and white hemp And arrow hemp, after the protocorm germinates, the longer the survival time, the higher the probability of contacting the ring bacteria, and the higher the yield of the white hemp and rice hemp (zero generation species) formed by the higher probability, the higher the yield of the germinating bacteria It has strong vitality and provides nutrients for the protocorm of Gastrodia elata for a long time, so it is necessary to improve the medium f...
