Rice husk is a good "soil" ingredient for cultivation of bacteria and cultivation of gastrodia in plain areas. The “soil†that it composes is the filler, which has the characteristics of looseness, ventilation, good water permeability, and rich nutrition, which is beneficial to the growth of Armillaria mellea. The mycelium on the mycorrhizal and mycelium cultivated with it is thick and strong, and the cultivated gastrodia grows well. The method is as follows: (1) Rice husk and yellow sand of rice hull culture are each 1 part (volume ratio is 1:1) or 3 parts of rice hull and 2 parts of yellow sand, and add water and mix well, and the humidity is 40%. As a culture medium for culturing Armillaria mellea. Culture of bacterial culture: Spread 1-2 cm thick rice husk and yellow sand mixed culture material at the bottom of the fungus file, put 2 new wood materials and 1 honey fungus seed material on top, cover each other side by side, then cover 3 cm The left and right thick culture materials are spread out and fill the gaps. In this way, one cellar can be stacked in layers of 3-5 layers, and it is also possible to use cell cultures and new materials. If you engage in a fixed bed, you can use 2-3 layers. In order to prevent the surface of the bacteria bed from washing out the rice husks and reducing the evaporation of water when it is watering, an additional 1.5 cm of sand or sand may be added to the bed surface. After the cultivation, pour one permeable water, and then strengthen the management to maintain sufficient humidity in the pit. At the temperature of 20-26°C, after 25-30 days, the new material can be covered with fungus. Using this method to cultivate bacteria, fast bacteria, thick and strong fungus, and no contamination with bacteria, and local materials, economic convenience. (2) Cultivation of Gastrodia Elata with Rice Hull When growing gastrodia elata, the filler used for the cultivar can continue to be used, or it can be separately compounded as described above. However, the amount of water used should be slightly less. It is advisable to use a finger joint to hold the water. If too much water, harmful to the planted gastrodia; the result of too little water, adverse bacteria, and affect the growth of Gastrodia. The specific cultivation method is the same as other cultivation methods. However, the cellar and the box must be filled in order to maintain moisture and prevent contamination with germs. The use of rice husks to cultivate gastrodia, as long as the management is well, the bacterial growth of bacteria, and the establishment of the relationship between seedlings early, normal growth of Gastrodia, can also achieve the desired effect. (3) Management measures with rice husk culture and cultivated gastrodia as the fillers in the rice husk and yellow sand are loose and have poor water retention performance. In addition to the cultivation of bacteria, the cellar or box surface is covered with a layer of sand. Or outside the soil, the number of watering should be increased appropriately. Especially in the vigorous growth season of Tianma, Tianma needs more water. In the dry season, if the air humidity is low and the amount of evaporation is large, watering must be performed in time. When watering, it should be poured lightly to avoid pouring of water, which is beneficial to the growth of Armillaria mellea and Gastrodia. Gastrodia elata production and management are also high. On the contrary, due to the humidity is too small, it will affect the growth of both and reduce the production of Gastrodia. . China Agricultural Network Editor
