Problems solved by technology

In addition, Pleurotus ostreatus has high requirements on water during cultivation, and the water needed for its growth mainly comes from the medium, and the water content in the medium has a great influence on the growth of mycelium and the increase of fruiting body yield , once the water is short of water or the water supply is not timely, the growth of mycelium or fruiting body will slow down or even stop, and the yield will be greatly reduced

Abstract

The invention discloses a pleurotus ostreatus culture medium and a preparation method thereof, and relates to the technical field of edible fungus cultivation. The culture medium is prepared from, byweight, 60-70 parts of corn straw, 10-20 parts of bagasse, 5-10 parts of corn flour, 2-5 parts of chicken manure, 1-2 parts of shell powder, 0.3-0.7 part of potassium dihydrogen phosphate, 0.2-0.6 part of magnesium sulfate, 0.1-0.4 part of ferrous sulfate, 1-2 parts of lime, 0.7-1.4 parts of sucrose and 0.2-0.8 part of cottonseed peel-based water retention agent. By means of the culture medium, sufficient carbon and nitrogen sources can be provided for the growth of pleurotus ostreatus, continuous water can be provided for pleurotus ostreatus in the process of planting pleurotus ostreatus, theproblems of water loss and water supply of the culture medium in the cultivation process of pleurotus ostreatus are solved accordingly, the labor amount is reduced, the pleurotus ostreatus culture medium is used for planting pleurotus ostreatus, the yield of pleurotus ostreatus can be significantly increased, the quality of pleurotus ostreatus can be significantly improved, the bagging time and fruiting time of mycelia are shortened, and the culture medium has high application and popularization value.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a culture medium for oyster mushrooms and a preparation method thereof. Background technique [0002] Pleurotus ostreatus, the scientific name of Pleurotus ostreatus, the edible taste of oyster mushroom is fresh and tender, smooth, rich in taste, and compact in texture. It is widely promoted and planted as the main edible fungus in daily life. Pleurotus ostreatus is rich in nutrients such as protein, carbohydrates, and reducing sugars. Its protein content is 2.6 times that of eggs, which can supplement the amino acids and nutrients needed by the human body. Oyster mushrooms also have anti-aging, anti-oxidation, anti-cancer and anti-inflammatory properties Cancer, antibacterial and anti-inflammatory effects, has a high edible health value. [0003] In the cultivation of Pleurotus ostreatus, a good medium is the basis for its high yield. In addition, Pleurotus o...
