Discussion on the experience of cultivating Lentinus edodes in Duanmu

Among Lentinus edodes, Duanmu Lentinus edodes is very popular among consumers. The author has been engaged in the cultivation of Lentinus edodes for decades, and the practical experience is introduced as follows.

1. In addition to pine, fir, cypress and other oily and aromatic tree species, more than 200 kinds of trees such as white oak, sesame oak, Cyclobalanopsis glauca, maple, flower tree, chestnut, wild walnut and so on are suitable.

two。 Cutting and setting up the Winter Solstice can cut down trees, especially "nine days", which should not exceed Qingming Festival at the latest. Because the tree is dormant during this period, the cortex and xylem are closely integrated, the nutrition is rich, there are few miscellaneous bacteria, and the cut is conducive to the germination of new shoots of tree stubble.

3. The section should be sawed off, and the length should be flexibly controlled according to the size of the tree, and it is suitable to move conveniently, generally 1.0-1.2 meters.

4. Inoculation tools are generally made of a belt with a diameter of 10 to 12 millimeters, and holes can also be drilled with an electric drill, and the seeder should also prepare a small hammer.

5. Hole generally 1 meter long section of wood (small head left 12 cm) can be hit 4 lines, 9 in each row, the hole depth should be more than 1 cm into the xylem after breaking the skin, in case of broken skin, scar, section scar can add 1 more cave.

6. Vaccination should be paid attention to while drilling holes, do not make holes in the morning, inoculation in the afternoon, not overnight, nor in rainy days or hot sun vaccination. Require vaccinators to wash their hands first, then put some bacteria powder into the hole, and then put small wood bacteria and hammer to knock tight, the amount of inoculation should be large, do not save species.

7. The upper pile of bacteria can be stacked in the form of "mountain", firewood, upright, etc., especially in the upright type (requiring small head landing). In case of low temperature or rainy days, you can cover the film, but pay attention to ventilation, pile and cover weeds and branches to prevent the sun and rain. The sterilization time is about 50 days, pay attention to "dark germ", the site should be clean and dry, and it is more ideal if you can inoculate, infect and raise bacteria on the mountain.

8. After about 50 days of inoculation, you should turn over the pile to check the survival of the strain, pull out the small cork of the strain, take white as good, dry in yellow, and black as dead (if the strain has turned white in appearance, there is no need to pull out the seed to check). It is found that the dead seed can be replenished to recover the loss. Then use the "#" shape or "imbricate" stacking, pay attention to maintain a certain distance between the mushroom wood and the mushroom wood, in order to facilitate ventilation. Enter the bactericidal stage, still need to cover with branches and weeds, keep the dark sun exposure, it is best to turn the pile every 1-2 months. Due to high temperature and drought in summer, mushroom farms with conditions should spray water to cool down (do not spray at noon), keep the pile "dry and wet", and pay attention to pest control. The whole culture period is about 8 months to one year.

9. Management of mushroom production from spring, summer and autumn to late autumn and early winter, when the average temperature drops to about 15 ℃, "news mushrooms" will grow when there is a certain amount of rainfall. At this time, the mushroom farm should be "six wet and four dry", the air relative humidity should be about 85% and 90%, and the light should be kept "six yin and four yang".

10. In order to facilitate the growth and picking of Lentinus edodes fruiting body, select the appropriate time to frame wood to produce mushrooms. According to the actual situation to adopt "herringbone", "imbricate" different forms of frame wood. When setting up wood, the mushroom wood hits the ground with a small head and a big head upward, which can prolong the life of part of the bark and increase the mushroom yield. It is necessary to prevent mushroom wood from emerging from shelf wood before it reaches physiological maturity.

11. Lentinus edodes can be picked when the mushroom grows from seven to medium well, and the edge of the cover is still in the shape of a "gong edge". Harvest is best carried out on a sunny day, pinch the base of the mushroom stalk with your hands, gently unscrew it, and you must pick clean mushroom feet.

twelve。 Dry "Lentinus edodes incense from baking". After harvest, put the shiitake mushrooms into the baking sieve one by one, face up to the handle, and bake on the same day. The baking temperature is low first and then high. Do not exceed 40 ℃ at the beginning, increase 5 ℃ every 3 to 4 hours, and do not exceed 65 ℃ at most. After the handle is hard, it can be packed for sale.
