Lentinus edodes section wood cultivation

After cutting down the trees suitable for the growth of Lentinus edodes, cut the branches and stems into segments, then inoculate them artificially, and then concentrate on artificial scientific management in the sites suitable for the growth of Lentinus edodes. This method is called the cultivation of Lentinus edodes.

First, the preparation of mushroom wood

1. The choice of mushroom wood is suitable for the growth and development of Lentinus edodes, including chestnut, oak, mistletoe, birch, Juglans mandshurica, elm, raw red poplar and so on.

As the trees needed for the production of Lentinus edodes, 15-30-year-old trees are the most suitable. The diameter of mushroom wood is 5-20 cm in diameter.

2. The selected trees should be cut down in time, and the felling period is better in late autumn and winter. At this time, the tree is rich in nutrition, the sap flow is slow or stopped, and the bark is not easy to peel off. because the cells of the felled trees will not die immediately, they should not be inoculated immediately. They should be left in place for several days, and only after the trees have lost some water can they be shaved and transported to the mushroom farm. In the process of felling and handling, the bark must be kept intact. The hyphae without bark are difficult to colonize and to form primordia and mushroom buds.

3. The logs transported to the mushroom farm should be naturally air-dried for a period of time, and the length of air-drying time should be determined according to the water content of different tree species. When the water content of mushroom wood is 35%-45%, it is most suitable for mycelium growth and development. The water content can be judged according to the cracks in the cross section of the mushroom wood. Generally, when the fine crack reaches 2 to 3 of the diameter of the mushroom wood, it reaches the water content suitable for inoculation. At this time, the mushroom wood can be cut into a wood section of about 1 meter, and the mushroom wood should be of the same length, which is convenient for stacking and erection operation.

Second, the choice of mushroom farm

Mushroom farms should choose places with rich tree resources, convenient transportation management, sunny ventilation and good drainage. The mushroom farm is best located under a sparse broad-leaved forest or under an artificial shade, requiring four suns and six shades, and flowers refract where the sun can penetrate. There should be streams and other water sources near the mushroom farm to facilitate water management. The average annual air relative humidity is about 70%, and the best soil quality of the mushroom farm is the sandy soil with many gravel, which can make the environment of the mushroom farm clean, and the mushroom wood is not easy to get sick and give birth to insects.

III. Vaccination

The main results are as follows: 1. The best time for inoculation is when the temperature is about 15 ℃. Although the bacteria are slow when the temperature is low, the chance of contamination by miscellaneous bacteria is less.

2. The cultivated species of Lentinus edodes prepared by inoculation methods include sawdust bacteria and cork bacteria, so there are two inoculation methods.

The main results are as follows: (1) before the sawdust inoculation method, drill or punch holes in the mushroom wood with a depth of 1.5-2 cm, an aperture of 1.5 cm, a row spacing of 6-7 cm, a hole spacing of 10 cm and a zigzag arrangement. When inoculating, take a handful of sawdust and fill it into the inoculation hole, then cover the pre-prepared bark on the inoculation hole and gently knock it flat with a hammer. Corncob can also be used as a cover, first knock the corncob into the inoculation hole one by one with a hammer.

(2) Cork strain inoculation method this method generally uses round table-shaped cork bacteria, but also round cork strains, and the seeds should be prepared according to the size of the inoculation hole. Punch a hole in the mushroom wood before inoculation, then plug a cultured cork into the hole and knock it flat with a hammer.

Fourth, the upper pile of bacteria

The process of bacteria generation is to stack the inoculated mushroom wood together according to a certain format, make the mycelium colonize quickly, and spread to the mushroom wood under suitable temperature and humidity conditions. When the fungus is infected, the stacking methods of mushroom wood are as follows:

The main results are as follows: 1. The well shape is suitable for the conditions of flat terrain, high site humidity and sufficient water content of mushroom wood. First of all, put a sleeper on the ground, stack the inoculated mushroom wood into a small pile 1 meter high, and cover the top and sides of the pile with branches or thatch to protect against the sun, keep warm and moisturize.

2. Horizontal stacking mushroom farm has moderate humidity and ventilation, so horizontal stacking can be used. Pile the sleepers horizontally, and then stack them in the same direction. The heap is about 1 meter high, and the upper or sunny side is covered with thatch.

3. The tile type is suitable for the drier mushroom field. First, a thick sleeper is placed horizontally on the ground, then 4-6 mushroom trees are placed obliquely, and so on.

In addition to the above three placement methods, there are archway, standing wood and triangle placement methods, a mushroom farm can be flexibly selected according to the actual situation.
