Lightweight container seedling culture medium containing needle mushroom bran

Abstract

The invention relates to a lightweight container seedling culture medium containing needle mushroom bran. The lightweight container seedling culture medium consists of the needle mushroom bran, grass carbon and rice hulls in a volume ratio of (2-4):(3-5):(2-4) and azophoska of 1.5-2.5kg/m<3>. The lightweight container seedling culture medium provided by the invention has the beneficial effects that (1) the needle mushroom bran is a waste material generated during the production of needle mushrooms, and is prepared into a seedling substrate after being fermented and decomposed, so that the problem of environmental pollution caused by stacking of the needle mushroom bran can be solved, natural resources are well utilized, a good culture medium is provided for the seedling industry, and meanwhile the industry chain of edible fungi is expanded; and (2) while the quality of container seedlings is ensured, the needle mushroom bran is used for replacing part of the grass carbon to ensure that the usage amount of the grass carbon is reduced to 36-42% from the traditional 60%. The reduction of the usage amount of the grass carbon reduces the production cost of the container seedlings, and a production process and an operation method of the container seedlings are not needed to be changed.

Description

(1) Technical field [0001] The invention relates to a light-duty container seedling cultivation substrate containing flammulina velutipes chaff. (2) Background technology [0002] Container seedling cultivation, especially light substrate container seedling cultivation technology, has been widely accepted and applied by foreign forestry developed countries because of its advantages such as small seeding amount, short seedling cultivation cycle, easy industrialization, effective extension of afforestation time, and significant improvement of afforestation results. The key to container seedling cultivation is the substrate. At present, most of the substrates used in container seedling cultivation use peat as the main raw material, and the usage amount is very large, reaching about 60%. Peat is mainly produced in the Northeast of my country. It is a non-renewable resource subject to geographical restrictions. Exploitation will definitely cause the exhaustion of this resource a...

Problems solved by technology

Shiitake mushrooms and black fungus chaff are used as seedling matrix raw materials. Although previous work has been done, shiitake mushrooms and black fungus use broad-leaved wood chips as the main cultivation materials, and at present they can only be cultivated by hand in one household. The chaff has a collection radius The problem is that fungus chaff is collected from each household, which is costly and not conducive to industrialization
