There are two main types of black fungus cultivation techniques, namely deep pit planting and shallow pit planting.
The pit is planted with a width and depth of one meter, and the length is determined according to the terrain and the number of ear trees. On top of the pit, you can build a shelf with sticks or pieces of bamboo, and spread branches. At the bottom of the pit, a narrow ditch is dug on both sides, and the middle is used as a managed aisle. This method is less affected by the external climate, the humidity is easy to guarantee, and the water application and harvesting are convenient. In late autumn, when the temperature drops, you can remove the shelter from the shed and cover it with a film to keep it warm. This is currently a method with higher yields.
The pit planted in the shallow pit is one meter wide and 33 cm deep, and the length is not limited. You can put a piece of wood on both sides of the bottom of the pit, put the ears and eyes vertically on the sleeper, and then continue to put the second layer, put up a shelf, and cover the film according to the weather and other factors. There is no managed passage inside the pit and the inside is too low to be accessible. When turning the wood and harvesting, it is necessary to remove the mulch on it, and after the harvest is completed, it is necessary to re-cover it, which is more troublesome. And its yield is not as good as that of deep pit cultivation.
1) There are many species of ear wood for cultivating black fungus, such as tree species of the family Shellaceae and Birch family. Ear wood should be selected at breast height with a diameter of 10 12 cm, cut down into 1 1In the 2m long section, the section is painted with new lime, and then placed in a ventilated sunny place.
2) The tools used for inoculation should be sterilized with ethanol in advance. First, use an electric drill on the ear wood to shoot a vertical depth of 1 with a hole distance of 7cm5cm holes, if sawdust strains are used, the holes should be filled, and the prefabricated bark cover should be covered after pressing tightly. After the shoot is inserted into the inoculation hole, it is hammered tightly to make it flat and porous with the surface of the segmented wood.
3) The biological characteristics of black fungus are that the hyphae can grow between 6 36, but 22 32 is the most suitable;15 and 27 can all be differentiated from entities, but 20 24 is the most appropriate. The mycelium can grow in the cultivation material and segment wood with a water content of 60 70, and the water content of the ear wood is required to be more than 70 and the relative humidity of the air is 90 95 when the fruiting body is formed. Mycelium grows normally in the dark, and the fruiting body needs a light intensity of 250 1000 lx during the growth phase. For aerobic fungi, pH5 56 is most suitable.
4) In the planting process, it is also necessary to carry out the prevention and control of pests and diseases to ensure the growth and yield of black fungus.
In short, the black fungus planting technology includes deep pit planting, shallow pit planting, and the technology of ear wood preparation, inoculation, and planting management. Mastering these techniques and paying attention to the relevant details can lead to the successful cultivation of high-quality black fungus.
