What are the cultivation techniques of Lentinus edodes? Analysis of Linden cultivation techniques of Lentinus edodes

The common cultivation of Lentinus edodes are section wood cultivation and substitute cultivation. Substitute cultivation can be divided into many ways, such as brick culture, bag cultivation of Lentinus edodes, soil-covered cultivation of Lentinus edodes and so on. Next, let's take a look at the Linden cultivation technology of Lentinus edodes.

The production method of Lentinus edodes in many parts of our country is often used in the cultivation of Lentinus edodes, that is, after the trees are cut down and properly dried, the cultivated pure bacteria are connected to the section wood, so that the hyphae are planted in the section wood, and the fruit body of Lentinus edodes is grown and developed.

The cultivation and production steps of Lentinus edodes are as follows:

1. If you choose the wood of the mushroom farm to cultivate Lentinus edodes, you can choose the site near where the mushroom wood is cut, generally in the sunny part of the middle of the mountain, near the water source, or build a shade shed on the open land as a mushroom farm. The two-field system is generally adopted, that is, the "fungus field" and the "mushroom field" are separated. The germicidal stage takes a long time, so the management can be relaxed, so the site chooses east and south, while in the northwest, the sunshine is insufficient and it is vulnerable to cold wind. According to the biological malignancy of Lentinus edodes, the selection of mushroom field should create environmental conditions suitable for the growth and development of Lentinus edodes, and control measures such as temperature, humidity, light and so on.

two。 Betula platyphylla, poplar and willow are the best trees for wood cultivation. Pine, cypress and other trees contain phenols and emit a pungent smell, usually not used. When selecting section wood, we generally choose wood with more nodules, more bark cracks, solid wood, more sapwood, less heartwood, thicker bark and less easy to fall off. This kind of tree has good nutrition storage. The diameter should be about 10-15CM.

3. The inoculation period is better early than late, because the temperature is low, the activity of miscellaneous bacteria is poor, it is not easy to invade the wood, and the mycelium grows in the tree for a long time, which is beneficial to fully decompose the wood, absorb nutrients, mature ahead of time and produce mushrooms earlier. The fungus wood used for inoculation must be fresh, strong vitality, and the interior must be thoroughly developed; sawdust bacteria should be fresh, non-aging, no miscellaneous bacteria and appropriate age.

Common tools for Lentinus edodes:

The main results are as follows: (1) the tools of drilling machine usually use electric drill or punch, and the diameter of drill bit is about 1.2-1.3CM. It is difficult to inoculate with small hole, less seed, slow growth and easy to crack bark when the hole is large. The use is laborious and inefficient.

(2) the sealing material can be bark, paraffin, gypsum or yellow mud without organic matter.

(3) other tools, such as brackets for drilling, scrapers, inoculation tweezers, etc., which are pre-soaked with 0.1% potassium permanganate.

The water content of the section wood should be determined before inoculation, and it can be inoculated when the water content is about 50%. The steps of inoculation are as follows: ① drilling: first use an electric drill to drill holes on the section wood, generally with a hole depth of more than 2CM, at least deep into the xylem 1CM, and crisscross the finished zigzag holes around the section wood, with a vertical spacing of 7-9CM and a horizontal spacing of 5-7CM. ② inoculation: after drilling a small piece of bacteria into the hole, the volume should not be too much, in order to fill the hole, do not tamp it with sticks and other things. ③ cover: after the bacteria are installed, cover the bark on the hole immediately and gently beat it firmly with a hammer to make the bark better and the surface of the wood Xiangping. In actual operation, another perforator with less caliber is often used to remove the cover in order to make the cover firm. The hole is neither protruding nor sunken, the depression is prone to stagnant water rot, protruding is easy to be touched off, so that the strain is dry or eaten by insects. In order to ensure the firmness of the wood cover, paraffin can also be used to seal the seal. The formula of paraffin sealing material is: paraffin 75%, rosin 20%, lard 5%, heated and melted, after cooling, apply to the lid with a brush, and stick firmly after cooling.

When inoculating, try to make drilling, inoculation and sealing work smoothly, and punch a hole after inoculation, so as not to affect the bacteria caused by dryness or pollution of the hole wall. Then carry on the fungus base mushroom production management.
