Description
Technical Field
The invention relates to the field of agricultural production, in particular to a production method of pleurotus eryngii.
Background
Pleurotus eryngii, also called Pleurotus eryngii, is a new rare edible fungus product with integration of edible, medicinal and dietetic functions, which is developed and cultivated successfully in recent years. The mushroom body has the fragrance of almond, fleshy and thick meat, fresh and tender mouthfeel, fragrant taste and rich nutrition, and dozens of delicious foods can be cooked. The pleurotus eryngii is rich in nutrition, is rich in protein, carbohydrate, vitamins and mineral substances such as calcium, magnesium, copper, zinc and the like, can improve the immunologic function of a human body, has the effects of resisting cancer, reducing blood fat, moistening intestines and stomach, beautifying the face and the like on the human body, also has the effects of reducing blood fat, reducing cholesterol, promoting gastrointestinal digestion, enhancing the immunologic capability of the organism, preventing cardiovascular diseases and the like, and is popular with people.
In the process of spawn running culture of the pleurotus eryngii, the after-ripening time is longer, the culture period is generally 35-40 days, the production period is longer, but the culture period is too short, such as 20-28 days, and the fruiting rate is low and is only about 70%.
Disclosure of Invention
The invention aims to provide a production method of pleurotus eryngii, which can reduce the production period of the pleurotus eryngii, improve the fruiting rate and solve the problem of low fruiting rate caused by short production period.
The invention is realized by the following technical scheme:
the production method of the pleurotus eryngii comprises the following steps of culture treatment: culturing Pleurotus eryngii at initial temperature of 22-24 deg.C for 10 days for field planting, increasing the temperature by 0.8-1.5 deg.C for the next 10 days, culturing for growth, and increasing the temperature by 3-5 days for 4-5 deg.C for complete maturation.
In the culture growth process, the temperature is increased in three stages: a first stable temperature raising stage is carried out for 1-2 days in the early stage of the culture growth, a temperature stabilizing stage is carried out for 4-6 days in the middle stage of the culture growth, and a second stable temperature raising stage is carried out for 1-2 days in the later stage of the culture growth, wherein the temperature is raised by 0.3-0.6 ℃ in the first stable temperature raising stage, and the temperature is raised by 0.5-0.9 ℃ in the second stable temperature raising stage.
During the complete maturation process, the temperature is raised in 2 stages: the temperature is raised by 2-3 ℃ in 1-2 days and 1-2 ℃ in 2-3 days.
Also comprises fruiting treatment: the fruiting temperature is gradually reduced according to the fruiting period, the illumination time, the humidity and the carbon dioxide concentration are adjusted according to the fruiting period in a matching mode, the whole-day illumination treatment is carried out in the first half of the fruiting period, the humidity is controlled to be 80-90% in the second half of the fruiting period, and the carbon dioxide concentration in the fruiting period is matched with the change of the fruiting temperature to carry out the treatment mode of firstly reducing and then increasing.
The fruiting time period is divided into five periods, and the time period of the five periods changes from decreasing to increasing.
The temperature reduction is carried out according to five different periods with the amplitude of 1-3 degrees, and the initial temperature is 16-17 ℃.
Ventilating every 6 hours during fruiting, and increasing the ventilation time for 1 hour.
The concentration of carbon dioxide is controlled to be 4000-5000ppm in the first stage, to be 2000-3000ppm in the second stage, to be 3500-4500ppm in the third stage, and to be 6000-8000ppm in the fourth and fifth stages.
The temperature is gradually increased to help the hyphae to grow and obtain enough growth efficiency, the hyphae are cultivated at about 28 ℃ when the pleurotus eryngii is cultivated in the prior art, after the hyphae grow fully, the pleurotus eryngii grows after being mature, and the hyphae are cultivated at a certain temperature value when the pleurotus eryngii is cultivated after being mature, so that the growth space of the pleurotus eryngii in the post-maturation period is ignored. The inventor of the invention raises the temperature and cultivates the pleurotus eryngii by stages, so that the fruiting rate of the pleurotus eryngii is increased and the cultivation period is shortened.
The inventor further finds that the temperature raising mode is different and the growth of the pleurotus eryngii is also different, the temperature is raised by a small degree firstly, the temperature is stabilized in the middle period to be used for the growth of the pleurotus eryngii, and the temperature is further raised by a large degree on the basis of the vigorous growth of the pleurotus eryngii in the later period to continue the vigorous growth of the pleurotus eryngii. Therefore, the fruiting rate of the pleurotus eryngii is ensured while the culture period is shortened.
During the complete maturation period, the temperature increase is required to be opposite to that during the culture medium period, the temperature increase amplitude is required to be greatly increased in the front section of the period so as to collect the growth tail vigor of the pleurotus eryngii, and the temperature increase amplitude is required to be reduced subsequently to prevent the self metabolism of the pleurotus eryngii. The operation can fully utilize the growth space of the pleurotus eryngii in the post-maturation stage, and the timing is grasped to enable the pleurotus eryngii to grow dominantly, so that the culture period of the pleurotus eryngii can obtain higher fruiting rate, and the culture period of the pleurotus eryngii is effectively shortened.
The fruiting management mode is also greatly different from the existing management mode: according to the method, the fruiting temperature is gradually reduced according to the fruiting period, the illumination time, the humidity and the carbon dioxide concentration are adjusted according to the fruiting period in a matching manner, the whole-day illumination treatment is carried out in the first half of the fruiting period, the humidity is controlled to be 80-85% in the second half of the fruiting period, the carbon dioxide concentration in the fruiting period is increased after being reduced in a matching manner with the change of the fruiting temperature, and four factors can be reasonably adjusted to greatly and well improve the fruiting type. The mild gradual change of the conditions can lead the pleurotus eryngii to be continuously adjusted and adapted to the current environment in the continuously changing environment, deal with the discomfort caused by the environment and lead the mushroom type of the pleurotus eryngii to be good.
Compared with the prior art, the invention has the following advantages and beneficial effects:
according to the invention, the method for cultivating the pleurotus eryngii is improved, so that the pleurotus eryngii can obtain good fruiting rate in the cultivating process, the cultivating period can be effectively shortened, and the cultivating period can be shortened to 23-25 days.
