Agaricus bisporus covering soil

Abstract

The invention discloses agaricus bisporus covering soil. The agaricus bisporus covering soil is prepared from the following raw materials in parts by weight: 50-65 parts of turfy soil, 1.5-3 parts of lime powder, 0.5-1 part of a soil water-retaining agent, 20-30 parts of rapeseed dregs, 10-30 parts of edible mushroom bran, and 10-20 parts of a culture medium after spawn running, wherein the rapeseed dregs contain 10-12 percent of crude protein, 3-5 percent of crude fat, 40-45 percent of saccharides, 10-14 percent of saponin, 2-3 percent of tannin and 0.1-0.9 percent of caffeine; the culture medium after the spawn running is obtained by inoculating agaricus bisporus strains to a culture medium material, uniformly mixing and then performing spawn running culture for 14-21 days under closed conditions. The yield of agaricus bisporus in the covering soil is obviously higher than that in other soil input equivalently, the yield of the agaricus bisporus in the covering soil per square meter is high than that of the other soils by 1-2kg, the tide-turning period is short, the weight of mushroom monomers is large, a mushroom body is white in color and clean, and a mushroom surface is large in diameter.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a bisporus mushroom covered with soil. Background technique [0002] Covering soil is a necessary condition for Agaricus bisporus to change from vegetative growth to reproductive growth. So far, the world's most advanced Agaricus bisporus production technology still needs to use soil covering technology. Different soil materials directly affect the yield of Agaricus bisporus. [0003] At present, peat soil is mostly used in domestic industrial planting mode, and most of the industrialized natural mushroom sheds are local soil, and the disinfection method is to use chemical pesticides and bactericidal drugs to pile up for a period of time. This method of covering soil preparation is easy to produce Pesticide residues, residual pesticides are easily absorbed by Agaricus bisporus in the production of Agaricus bisporus, affecting the quality and taste of Agaricus ...

Problems solved by technology

[0003] At present, peat soil is mostly used in domestic industrial planting mode, and most of the industrialized natural mushroom sheds are local soil, and the disinfection method is to use chemical pesticides and bactericidal drugs to pile up for a period of time. This method of covering soil preparation is easy to produce Pesticide residues, residual pesticides are easily absorbed by Agaricus bisporus in the production of Agaricus bisporus, affecting the quality and taste of Agaricus bisporus, and then affecting the sales of Agaricus bisporus. In addition, it is too single and can only play the following two roles: 1. Provide a protective layer , so that the temperature change of the fungus bed and the evaporation of water are small, and the mycelia will not dry up due to dehydration, or shrink due to direct contact with water; 2. Gravity oppresses and stimulates the mycelium, and the mycelium originally grows in a rich nutrient environment In the middle, the nutrient environment became "thin" obviously after covering the soil, and the carbon dioxide concentration in the covering soil layer increased sharply, which forced the mycelium to become thicker and kink into the fruiting body primordium
