入冬后,树木开始冬眠,树液基本处于凝滞状态,枝干贮藏的营养物质比较丰富,树干中所含的水分相对减少,皮层和木质部结合紧密,砍伐后皮层不易脱落,有利于木耳的生长发育。实践证明,“九天”砍伐的耳木接种后菌种定植早,出耳快,杂种少,耳片朵大,肉肥,色深黑。“九天”砍伐耳木,要在“二、三九”天进行,一定在“四九”前砍完。耳木砍伐后,要进行剔枝,就是将3厘米以下没有利用价值的枝丫剔掉。剔枝时要保留1厘米左右的枝桩,不要砍伤耳木皮层,以防给杂菌入侵创造伤口。在剔枝的同时,要把耳木集中在高燥通风的地方,使其水分失散。 After winter, the trees begin to hibernate, the sap is almost stagnant, and the nutrients stored in branches and stems are relatively abundant. The water contained in the trunk is relatively reduced, and the cortex and xylem are closely integrated. development. Practice has proved that “nine days” cuttings of ear wood species colonized early, fast ears, less hybrids, large ears, meat fat, dark color. “Nine days” cut earmuffs, to be carried out in the “two or three nine” days, must be cut off before the “49”. Ear cut after logging, to carry out the branch, is less than 3 cm no value of the branches picked out. When picking branches to retain about 1 cm branches, do not cut ear wood cortex, to prevent the invasion of bacteria to create wounds. At the same time in the branch, the ear wood should be concentrated in high dry and ventilated place, make its water dispersed.
