Management and Catalytic Technology of Lentinus edodes in Winter and Spring

The management of Lentinus edodes in winter and spring is the management of mushroom production period, which determines the economic benefits.

The fruiting stage is a turning point from mycelial development to fruiting body development. The management work changes from the fungus room to the mushroom stage, and the mycelium must be physiologically mature. The standard of maturity: first, the hand holding fungus bag has a light trembling feeling; second, the verrucous substance production accounts for 3 ℃ of the bag surface area, and it becomes soft and elastic; third, the pigment secretion accounts for 2 times 3-1 shock 2 of the bag surface; fourth, the culture time is 60-70 days, and the effective accumulated temperature is 1200 ppm.

Before leaving the shed, we should first build a mushroom shed, which can be picked into two sheds, one to cultivate small mushrooms and the other to cultivate flower mushrooms. Out of the mushroom shed, it is appropriate to choose flat terrain, convenient drainage and irrigation, high dryness to the sun, close to pure water quality, centralized construction of the shed to facilitate the management of feed and discharge. The specifications of the mushroom period: 3.2-3.4 meters wide, 20 meters long and 2.2-2.4 meters high. You can put 2000 bags.

The optimum temperature for development of Pleurotus ostreatus is about 15 ℃. Grow vertically and horizontally, and the mushroom body is symmetrical. The suitable humidity is 85% and the light is mainly scattered light.

Management requirements for mushroom production period: early winter and early spring should be ventilated in the morning; deep winter should be ventilated from 12:00 to 4 p.m. When the temperature is high, the ventilation time is long; when the temperature is low, the time is short. To keep fresh air and humidity in the shed, grass curtains should be built on top of the small mushroom shed.

Flower mushroom is a kind of deformed mushroom produced by giving unsuitable living conditions in the production process of Lentinus edodes. The mechanism is that the growth of the cover surface becomes slow due to the stimulation of dry and low temperature, while the rapid growth inside the cover causes the cover to crack, exposing white mushroom flesh and forming flower mushrooms.

Different flower mushrooms are produced in different stages of young mushrooms, and chrysanthemum petal-shaped mushrooms are produced when the diameter of the cap reaches 2-2.5 cm. This kind of mushroom has the best quality and the highest price. When the diameter of the cap reaches 4-5 cm, the poor quality of Pleurotus ostreatus is formed.

The optimum temperature for the cultivation of Pleurotus ostreatus is 8-18 ℃, which requires a large temperature difference. The humidity is 65% 70% in the early stage and 55% 65% in the later stage. The cultivation of flower mushrooms needs strong light and humidity, otherwise it will form dry mushrooms inside and outside.

The standard for the bag of small mushroom shed to move to the flower mushroom shed is that the diameter of young mushroom cover is 2-2.5 cm. In winter, a sunny breeze is the best weather for cultivating mushrooms. In early winter and early spring, film mushrooms can be uncovered in the evening and morning. It is appropriate to uncover the film from 10:00 to 4 pm in the depths of winter. Cover the film at night.
