The black fungus sticks that have developed and matured completely need to be mulched, and the technical points are as follows:
 
Selection of mulching material
 
The material used for mulching should be selected from the soil below the cultivation layer of vegetable garden, and the original soil should be spread out and fully exposed to the sun first.
 
Mulch material processing
 
The mulch material will be crushed into 1~3 cm soil particles with soil crusher after exposure, then add lime powder according to 0.5%~1%, then spray with carbendazim and formaldehyde solution, mix well, until the soil particles are coated with liquid, smothering pile for about a week can be used.

Digging the border and setting the stick
 
The length of the border depends on the width of the greenhouse, the border width is 1~1.2m, and the depth of the border is 5~8cm higher than the height of the sticks. After digging the borders, spray carbendazim or lime water supernatant around and at the bottom of the borders to sterilize. Place the sticks vertically in the border, according to the plum pile method, the bags are spaced 1 fist distance apart, the horizontal view is a row, the vertical view is a row, and the oblique view is also a row.
 
Mulch management
 
After the sticks are placed, the treated mulch material will be mulched, the mulch thickness should be 3~5cm, not too thin, and not too thick. After mulching, then spray carbendazim or lime water to sterilize. After mulching, water thoroughly with big water at one time, and then water twice with big water about 7~8 days apart, so that the sticks can absorb enough water and the mycelium can regain vitality and be ready for mushroom production.
