Description
Technical field
The present invention relates to a kind of cultivating method for edible fungi, particularly relate to the cultivation method of a kind of southern area woodear.
Background technology
Woodear is the edible mushroom that a kind of China widely cultivates, and the section of mainly containing wood is cultivated and the foster two kinds of cultivation methods of bag cultivating at present.Traditional producing region of woodear northeastward and the Northwest, but along with black fungus bag plants the maturation of technology, the southern black fungus cultivation scales such as Zhejiang expand rapidly, its seed stage is summer, going out the ear phase is autumn and winter and spring, planting type is based on open country, intermittent spraying cultivation, and this kind of planting type convenient management, output is high, Functionality, quality and appealing design.
Southern area cultivating black fungus inoculation makes the rod time generally in annual mid or late August, at this period temperature more than 30 DEG C.Woodear belongs to cold-resistant To Be Protected from Heat type mushroom, too high temperature is unfavorable for the growth of woodear, the 2h when high temperature 40 DEG C is all dead for woodear mycelia, and the condition of southern high-temperature high humidity, more be conducive to spore germination and the growth and breeding of the multiple moulds such as Trichoderma viride, breed the fastest under 30 ~ 40 DEG C of conditions, slow down with the reduction of temperature, the harm of woodear is also alleviated thereupon.
For solving the problem, after having inoculated, bacterium rod being deposited in indoor, when temperature is higher than 33 DEG C, forced ventilation need being carried out to culturing room, and the loose heap of turning in time.Whole culture period, need to make regular check on and send out bacterium situation, remove contaminated bacteria rod in time, workload is large.As (Lu Yun etc. such as Lu Yun, southern area booth in winter cultivating Auricularia auricula-judae in bags technical essential, " edible mushroom ", 6th phase in 2003,27 pages) method of a kind of southern area cultivating black fungus is disclosed, comprising: between bacteria developing period, culturing room's temperature should control at 22 ~ 25 DEG C, do not reach this temperature just to heat, but be no more than 28 DEG C.Vegetative stage, the light of culturing room close to dark, will open door and window ventilation every day.
If woodear seed stage is postponed till September, not only winter ear (high-quality ear) yields poorly, and on the occasion of Used in Rainy Seasons of Southern Cities during spring ear, is difficult to the system of gathering and does, per unit area yield and benefit all effected, even occur loss.
Summary of the invention
The invention provides the cultivation method of a kind of southern area woodear, to solve the high problem causing the woodear underproduction of existing cultivation method bacterium rod pollution rate.
A cultivation method for southern area woodear, comprising:
