Background
Pleurotus tuber-regium (Fr.) SingPleurotus tuber-regium) The fungi are edible and medicinal fungi which can form fruiting bodies and sclerotium, are mainly distributed in tropical and subtropical regions and are only found in Yunnan and Hainan in China. Different from other sclerotium edible and medicinal fungi, only the fruiting body or sclerotium can be eaten, the fruiting body and sclerotium of Pleurotus tuber-regium can be eaten, especially the sclerotium is rich in protein, mineral, essential amino acid, beta-glucan and other substances, has very low cholesterol content, has the functions of immunoregulation, anti-tumor, antivirus, anti-hyperglycemia and the like, and has very high economic value. The Pleurotus tuber-regium sclerotium can be ground into powder and added into food, can also be used for extracting active ingredients for development of functional food and preparation of biological agent, can also be dried in the sun to prepare traditional Chinese medicine, and has wide and various applications.
The extensive nutritional and medicinal values of Pleurotus tuber-regium attract the increasing attention of consumers and researchers. However, the method is limited to the imminent exhaustion of wild Pleurotus tuber-regium resources, and many researchers are continuously exploring artificial cultivation techniques. At present, the artificial cultivation of the pleurotus tuber-regium by adopting different culture material formulas is greatly developed, for example, the cultivation of the pleurotus tuber-regium and the pleurotus eryngii by adopting cottonseed hull cultivation materials, the cultivation of the sophora japonica residue and the peanut hull by Moyunhui, the cultivation of the plum culture by using the root culture material of the podocarpus root sprout, and the like, so that the cultivation of the pleurotus tuber-regium under the forest or in a greenhouse is realized. However, the current limitations of these methods are the ability to form Pleurotus tuber-regium fruiting bodies, but the inability to guarantee 100% production of sclerotia and longer production cycles.

(3) after the substitute materials are grown and the bags are filled with the fungus, outdoor earth covering cultivation is simulated in a flowerpot with the diameter of 15-27 cm, organic soil is wetted by water, 300-400 mL of water is added into every 600 g of organic soil, a layer with the thickness of two knuckles is firstly paved at the bottom of the flowerpot, then a whole or broken substitute materials for growing the fungus are placed on the organic soil, a layer of thin soil is lightly covered, a proper amount of water is sprayed, a preservative film covers the opening of the flowerpot, and the cultivation is continued in an incubator at the temperature of 32-34 ℃;
(4) spraying water to the cultivation pot twice a day in the morning and at night in the first 5 days, spraying water to the inner part of the film after the mycelia grow out of the soil layer, keeping enough moisture and humidity in the pot, enabling the pleurotus tuber-regium mycelia to climb over the whole surface of the cultivation pot after 5 days, continuously cultivating for 3-10 days, moving to the indoor, spraying water once at the temperature of 25 ℃ for 2-4 days, and moving to the indoor for 30-40 days to grow sclerotia.
Compared with the prior art, the invention has the following advantages:
1. according to the invention, by improving the formula of the pleurotus tuber-regium cultivation material, a better material ratio is obtained, so that the cost is reduced, and the mycelial germination quality of pleurotus tuber-regium mycelium is ensured.
2. The pot culture method has the advantages that the mode of outdoor soil covering cultivation of the Pleurotus tuber-regium is simulated, uncontrollable performance of outdoor cultivation environment is avoided, and the pot culture method has ornamental performance, practicability and convenience.
3.
