Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to edible mushroom planting substrate technical field, specifically to a kind of completely replace bran with caragana powder mushroom planting substrate and preparation method thereof. BACKGROUND
[0002] In traditional mushroom planting substrate formula, bran mainly provides nitrogen source, and accounts for about 80% of total cost of substrate, due to the high price of bran, the production cost of mushroom is relatively high.
[0003] The crude protein content of caragana is 10.74%, close to the crude protein content (about 13%) in bran, and the crushed caragana powder can theoretically replace bran as a good nitrogen source, and the addition of caragana powder can reduce the carbon-nitrogen ratio of the substrate, and the total carbon content decreases while the total nitrogen increases, which is more suitable for the reproductive growth of mycelium in the later stage.
[0004] If bran is replaced by caragana powder, the production cost of mushroom can be reduced, and the utilization of agricultural and forestry waste resources can be promoted, and economic benefits can be improved. SUMMARY
[0005] In view of the problems existing in the prior art, the present application provides a mushroom planting substrate completely replacing bran with caragana powder, which effectively solves the problem of relatively high cost in mushroom production.

[0007] The present application also provides a preferred technical scheme of a mushroom planting substrate completely replacing bran with caragana powder, which is made of the following raw materials in the following amount: apple wood chips 65-75 parts, caragana powder 23-33 parts, lime 1 part and gypsum 1 part.
[0008] The present application also provides a best technical scheme of a mushroom planting substrate completely replacing bran with caragana powder, which is made of the following raw materials in the following amount: apple wood chips 70 parts, caragana powder 28 parts, lime 1% and gypsum 1%.
[0009] The particle size of caragana powder in the mushroom planting substrate completely replacing bran with caragana powder according to the present application is between 5-20 mm.
[0010] The present application also has another object, which provides a preparation method of a mushroom planting substrate completely replacing bran with caragana powder, characterized in that it comprises the following steps:
[0011] 1) the branches of the Caragana are exposed to the sun for 7-10 days under natural conditions, completely dried and then crushed and passed through a 5-20 mesh screen;
[0012] 2) the apple wood chips, Caragana powder, lime and gypsum are mixed uniformly according to the proportions;
[0013] 3) the water content is controlled to be about 55% and sufficient stirring is performed;
[0014] 4) the uniformly stirred mixture is bagged, sterilized at 105 degrees for 24 hours and then cooled to obtain the shiitake mushroom planting substrate.
[0015] The shiitake mushroom planting substrate of the present application, which completely replaces bran with Caragana powder, has the following beneficial effects compared with the traditional shiitake mushroom planting substrate formulation:
[0016] (1) the present application uses waste Caragana branches to produce Caragana powder, which replaces the more expensive bran, greatly reduces the production cost of the shiitake mushroom substrate on the basis of maintaining the yield, and thus improves the economic benefit;
[0017] (2) the present application uses Caragana powder to replace bran, which increases the overall lignin content of the planting substrate while maintaining the nitrogen content, providing more favorable conditions for the growth of shiitake mushrooms. BRIEF DESCRIPTION OF DRAWINGS
