Mushroom culture medium and preparation method thereof

Abstract

The invention discloses a mushroom culture medium and a preparation method thereof. The mushroom culture medium comprises the following raw materials in parts by weight: 8 to 12 parts of mineral powder, 20 to 30 parts of agricultural residue, 15 to 25 parts of saw dust, 1 to 3 parts of quick lime, 6 to 10 parts of compound cake fertilizer, 2 to 3 parts of nutritional element additive, 5 to 7 partsof cottonseed hull, 4 to 6 parts of wheat bran, 4 to 6 parts of insecticidal additive, 10 to 16 parts of water, 7 to 9 parts of humus soil, 3 to 5 parts of pond sludge, 4 to 6 parts of agricultural straw and 3 to 5 parts of industrial flour. According to the mushroom culture medium, the nutritional components are rich and balanced, the materials are loose and air-permeable, the generation rate ofthe mushroom is greatly increased, the quality of the mushroom is improved due to use of the insecticidal additive, and the mushroom has a certain health-care effect; meanwhile, in the preparation method of the mushroom culture medium, the raw materials are easily available, the process is simple, the production cost is greatly reduced, the environment is protected, the environmental pollution isreduced, and high practical value and good application prospect are achieved.

Description

technical field [0001] The invention relates to the technical field of edible mushroom cultivation, in particular to a mushroom cultivation substrate and a preparation method thereof. Background technique [0002] Shiitake mushrooms are not only delicious, but also rich in nutrition. They contain a lot of amino acids, vitamins and a variety of physiologically active mineral elements. They are often called healthy food. At present, cottonseed husks are generally used as raw materials to cultivate edible fungi. The content of cottonseed husks in such edible fungi cultivation materials accounts for 50% to 90% of the entire edible fungi cultivation materials. The nutrients contained in cottonseed husks are more suitable for consumption. However, in recent years, due to the decline in cotton prices, the planting area has decreased year by year, resulting in a large increase in the price of cotton seed husks and high cost of edible fungi cultivation. However, although the edible ...

Problems solved by technology

At present, people generally use cottonseed husks as raw materials to cultivate edible fungi. The content of cottonseed husks in this kind of edible fungi cultivation materials accounts for 50% to 90% of the entire edible fungi cultivation materials. The nutrition contained in cottonseed husks is more suitable for consumption. However, due to the decline in cotton prices in recent years, the planting area has decreased year by year, resulting in a large increase in the price of cottonseed shells, and the high cost of edible fungus cultivation

However, although edible fungi cultivated with cottonseed hulls as the main material can be harvested 2 to 3 times, the sum of the second and third yields is far less than the first yield, and the yield of edible fungi is unstable.

In addition, cottonseed husks contain a small amount of gossypol, and the special gossypol smell in cottonseed husks reduces the crude fiber content in edible fungi, and the produced edible fungi have certain defects in color, taste and flavor. low quality

[0003] In addition, vinegar residues, cassava residues, and straws of crops such as corn, rape, rice, and wheat are leftovers from industry and agriculture. , most farmers return it to the field as fertilizer or as fuel, without giving full play to its use value, and some farmers directly burn it in the farmland, causing serious pollution to the environment and becoming a social problem that governments at all levels have been banning for a long time
