How to use rice husk to cultivate bacteria and cultivate Gastrodia elata

Rice husk is a good "soil" ingredient for bacteria culture and Gastrodia elata cultivation in plain area. Its "soil", namely filler, has the characteristics of looseness, ventilation, good water permeability, rich nutrition and conducive to the growth of Armillaria mellea. The fungal cords on the branches and materials cultivated with it are stout and exuberant, and the cultivated Gastrodia elata grows well. The method is:

(1) Culture of rice husk bacteria.

Use 1 part of rice husk and 1 part of yellow sand (the volume ratio is 1:1) or 3 parts of rice husk and 2 parts of yellow sand, mix well with water, and the humidity is 40%, as the substrate for cultivating Armillaria mellea.

Fungus material culture: first spread 1-2 cm thick rice husk and yellow sand mixed culture material on the bottom of the bacteria file, put 2 new materials and 1 Armillaria mellea seed material, and then cover the culture material about 3 cm thick, smooth and fill the gap. In this way, you can stack 3-5 layers in one cellar, and you can also use mycelia and new materials to cultivate at intervals, such as a fixed working bed, 2-3 layers. In order to prevent the surface of the bacterial bed from washing off the rice husk and reducing water evaporation, the surface of the bed can be added with sand or sandy soil about 1.5 cm thick. After culturing, water was watered once, and then the management was strengthened to keep enough humidity in the cellar. At the temperature of 20-26 ℃, the new material could be covered with fungal cord after 25-30 days. By using this method, the bacteria can be cultured quickly, the fungal cord is strong and exuberant, and there is no miscellaneous bacteria pollution. at the same time, it is economical and convenient to use local materials.

(2) cultivation of Gastrodia elata with rice husk

In the cultivation of Gastrodia elata, the fillers used in the original culture can continue to be used, or they can be prepared separately according to the above-mentioned method. However, the water consumption should be slightly less, and it is appropriate to sew the fingers tightly to see the water. If there is too much water, it is harmful to the planted Gastrodia elata; as a result, too little water is disadvantageous to the bacteria and affects the growth of Gastrodia elata. The specific planting method is the same as other planting methods. However, the edge of the cellar and box must be filled in order to maintain humidity and prevent miscellaneous bacteria pollution. The cultivation of Gastrodia elata with rice husk can achieve the ideal effect as long as it is well managed, the fungus can grow quickly, the relationship with seed is established early, and the growth of Gastrodia elata is normal.

(3) the management measures of cultivating bacteria with rice husk and cultivating Gastrodia elata.

Because the filler made of rice husk and yellow sand is very loose and the water retention performance is poor, the watering times should be appropriately increased except that the cellar or box is covered with a layer of sand or soil when cultivating bacteria and planting flax. Especially in the vigorous growth season of Gastrodia elata, Gastrodia elata needs more water, such as the dry season, small air humidity, large evaporation, but also timely watering. When watering, it should be watered frequently to avoid heavy water, which is beneficial to the growth of Armillaria mellea and Gastrodia elata, and the yield of Gastrodia elata is also high. on the contrary, because the humidity is too low, it will affect their growth and reduce the yield of Gastrodia elata.
