Mushroom culture medium taking trimmed orange branches as main raw material and preparation method thereof

Abstract

The invention relates to a mushroom culture medium taking trimmed orange branches as a main raw material and a preparation method thereof, and belongs to the technical field of edible mushroom culture. The method is characterized by comprising the following steps of: after the trimmed orange branches are crushed, adding saw dust, bran, gypsum, glucose, urea and calcium superphosphate into the crushed orange branches, stirring the mixture uniformly, adding a proper amount of water into the mixture, adjusting the pH value of the culture medium to between 5.0 and 7.0, compacting and bagging the stirred raw materials to form mushroom sticks, and sterilizing the mushroom sticks to obtain the mushroom culture medium, wherein the raw materials comprise the following components in percentage by mass: 45 to 60 percent of trimmed orange branch granules, 20 to 30 percent of saw dust, 15 to 20 percent of bran, 1 to 3 percent of gypsum, 1 to 3 percent of glucose, 0.2 to 1 percent of urea and 0.2 to 1 percent of calcium superphosphate; and the water accounts for 50 to 65 percent of the total mass of the dry materials.

Description

technical field [0001] The invention relates to a shiitake mushroom culture medium with pruned citrus branches as the main raw material and a preparation method thereof, belonging to the technical field of edible fungus cultivation. Background technique [0002] Shiitake mushroom is the second largest edible fungus in the world and one of the special products in my country. It is known as "mountain delicacy" among the people. Lentinus edodes is rich in nutrients, known as the "Queen of Plants", rich in vitamin B group, iron, potassium, provitamin D, in addition, it also contains anti-tumor ingredients such as lentinan and lentinan that lowers blood lipids. Human metabolism, enhancing the body's humoral immune function, and improving the body's adaptability have a great effect, and it is a rare health food. [0003] Lentinus edodes is a wood-rot fungus, and its ideal cultivation raw material is hard broad-leaved tree segment wood and sawdust as the main material. With the d...

Problems solved by technology

[0004] China is a big citrus producing country. In 2007, the planting area reached 1.91 million hectares, and the planting area and output both ranked first in the world. Through the pruning of citrus trees, a huge amount of branches will be produced every year. These branches are generally used as firewood. Or throw it away at will, which not only wastes the lignin and nutrients rich in branches, but also causes a certain degree of pollution to the environment.
