A kind of sludge mushroom slag cultivation substrate suitable for Chinese pine growth and its method

Abstract

The invention discloses a sludge lentinus edodes residue growing media suitable for the growth of a Chinese pine and a preparation method of the sludge lentinus edodes residue growing media. The sludge lentinus edodes residue growing media is prepared from lentinus edodes residues and sludge, wherein the lentinus edodes residues are a mixture containing sawdust, wheat bran and starch accounting for 90 percent of the mixture and are sieved into particles with the particle size respectively of 0.5-2mm and 2-5mm, and the particles are compounded according to the ratio of 1:1; and the sludge is a powder with the particle size smaller than 0.5mm; and the sludge with the mass percentage of 20.0% is mixed with the lentinus edodes residues. The preparation method comprises the following steps: removing impurities, sieving compounding, sieving out the sludge powder, weighing and mixing according to the ratio and packaging. By adopting the sludge lentinus edodes residue growing media, nutritional ingredients such as moisture, mineral substances and the like needed in the seedling growing process of the Chinese pine are strengthened, and the function of water retention is fulfilled; and as the sludge and the lentinus edodes residues are effectively combined and utilized, the waste materials can be utilized to create economic benefit, the media problem of the Chinese pine in the seedling growing and production process can also be solved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of the growth and cultivation substrate of Chinese pine, and in particular relates to a sludge mushroom dregs cultivation substrate suitable for the growth of Chinese pine and a method thereof. Background technique [0002] As agricultural production waste, shiitake mushroom residue not only wastes resources but also takes up a lot of space due to slow natural degradation. Using shiitake mushroom residue as a cultivation substrate can not only make full use of resources, but also create certain economic value. However, the direct use of shiitake mushroom dregs will require frequent watering due to poor water retention, and nutrients need to be supplemented during plant growth, which will bring corresponding troubles to cultivation and production. Due to the high content of organic matter and colloid, the sludge cannot be used directly as a substrate. By mixing the two and finding the content of mushroom resi...
