Composite substrate comprising mushroom bran waste and used for culturing watermelon and muskmelon seedlings and preparation method therefor
2015
The present invention discloses a composite substrate comprising mushroom bran waste and used for culturing watermelon and muskmelon seedlings and a preparation method therefor, and relates to a watermelon and muskmelon seedling culturing substrate and a preparation method therefor. The substrate provided by the present invention aims to solve the technical problem that the production cost of the substrate is increased as the fermentation period is long when conventional mushroom bran is used as a seedling culturing substrate. The composite substrate comprising mushroom bran waste and used for culturing watermelon and muskmelon seedlings provided by the present invention is prepared from oyster mushroom residues, shiitake mushroom residues and soil. The method comprises: 1, mixing the stacked oyster mushroom residues and the stacked shiitake mushroom residues with the soil, adding water, and constructing a stack to perform stack fermentation; and 2, carrying out secondary stacking: when a center temperature is 40-55 DEG C, performing primary turning; when the center temperature is 60-80 DEG C, maintaining the temperature for a week; and when the temperature falls, performing secondary stacking until the temperature does not rise again to obtain the seedling culturing substrate. According to the composite substrate comprising mushroom bran waste and used for culturing watermelon and muskmelon seedlings and the preparation method therefor provided by the invention, the production cost is lowered, and excessive exploitation of peat resources is reduced. The composite substrate comprising mushroom bran waste and used for culturing watermelon and muskmelon seedlings and the preparation method therefor are applied to the field for preparing the watermelon and muskmelon seedling culturing substrate.
