Description

The batch production bag is planted the bacterium fruiting technology of disturbing of Asparagus

Technical field

The invention belongs to field of edible fungus culture, specifically, the present invention relates to a kind of bag of cultivation Asparagus and disturb bacterium fruiting technology.

Background technology

Industrialized cultivation for needle mushroom originates from Japan, pass to subsequently Taiwan and Korea S, along with both sides of the Straits are open, Taiwan investment Asparagus enterprise introduced the bottle formula cultivation of technology-intensive type domestic in 1991, be introduced at that time economic relatively advanced Guangzhou, meanwhile, in Jinjiang in Fujian, Zhangzhou Area is on the basis of the seasonal cultivating flammulina velutipes of tradition, also begin to carry out the trial of anniversary batch production pocket type cultivation Asparagus, achieve success.Subsequently, closely about ten years, bottle is planted and two kinds of golden mushroom plantation patterns of bag cultivation are rapidly developed in China.

In recent years, along with the development of edible mushroom industry, spring bamboo emerges in large numbers in various places behind the anniversary factory culture elephanta, industry competition pressure constantly increases, and edible mushroom enterprise is faced with and updates technique, promotes quality and per unit area yield, raise labour efficiency the problem that reduces production costs.Also exist huge pressure in the same Asparagus production: bag is planted to produce and is born directly that mushroom yields poorly, poor quality, and the regeneration fruiting cycle is long, moreover bag cultivation production labor is many; Along with labor cost constantly increases, the higher bottle cultivation pattern of pattern steering mechanical degree is constantly planted by the more bag of recruitment by edible mushroom enterprise, but bottle plant to be produced and also to be existed the problem such as have high input, cost is high, technology is difficult, have a big risk, and makes a lot of medium-sized and small enterprises hang back.

Summary of the invention

For these reasons, the invention provides a kind of bag of cultivation Asparagus and disturb bacterium fruiting technology, this technology between bag plant and bottle cultivation technology between, both solved bag plant produce in long, the inferior problem of growth cycle, expensive, the technical difficulty in avoiding again bottle to plant producing and excessive risk.The main feature of present technique is for disturbing the bacterium technology: after bacterium sent out full by the bacterium bag, the temperature of progressively regulating storehouse to 12-14 ℃, humidity is that 90-100%, gas concentration lwevel are the regulation and control factors such as 3000-5000ppm, illumination 500-700LX, slice off sack apart from charge level 0.5cm place, then disturb bacterium, the old mycoderma of charge level is removed, carry out immediately mycelia recovery, existing former base, until the former base differentiation of regenerating; Progressively reduce temperature to 4-7 ℃ etc. after the former base differentiation, humidity is controlled at 80-90%, gas concentration lwevel is 5000-10000ppm, when growing to 3-4cm Deng the mushroom flower bud, the mushroom cap carries out bagging when the 0.15-0.25cm size processes, make the neat vertically growth of Asparagus, then carry out cold light lamp and intermittently suppress to process 2-3 hour/day; Treat mushroom cap uniformity and size at 0.35-0.45cm mushroom handle during in the 7cm left and right sides, adjusting temperature is 6-8 ℃, and humidity is at 75-85%, gas concentration lwevel is 10000-15000ppm, dark culturing is to the mushroom cap 1cm, and height is gathered when reaching physiological ripening when 15-18cm.

Embodiment

Embodiment provided by the invention all carries out according to routine operation or the condition of manufacturer's suggestion.

Bag is planted the production technology that Asparagus is disturbed the bacterium fruiting, mainly comprises following step:
