Embodiment 1

[0019] (1) Cover soil improvement and sterilization: The cover soil composed of peat soil dug from the pond has been cultivated for a round of Agaricus bisporus (harvesting 2 crops of mushrooms). Use high-pressure steam to sterilize and heat to 56°C, keep warm for 8 hours, open the fresh air damper to 10%, and cool to 20°C. Spray 3L / m 2 γ-PGA water immersion solution, mix well, pour 1.5L / m again after 1.5h 2 Water, mix well, pour the second time 1.5L / m after 1h 2 Water; the moisture content of the covering soil is 63%. Use lime to mix into the covering soil according to the ratio of 5% (mass ratio, the same below) of the covering soil, so as to increase and stabilize the pH at 7.5.

[0020] (2) Feeding and covering soil: sow the bacteria of Agaricus bisporus to the compost (compost), cultivate at 25°C for 18 days, and the mycelium will be covered with the compost; the temperature will rise at this stage, and the temperature can be controlled by adjusting the wind speed of t...

Embodiment 2

[0026] (1) Cover soil improvement and sterilization: The cover soil composed of peat soil dug from the pond has been cultivated for a round of Agaricus bisporus (harvesting 2 crops of mushrooms). Use high-pressure steam to sterilize and heat to 56°C, keep warm for 8 hours, open the fresh air damper to 10%, and cool to 20°C. Spray 2.5L / m 2 γ-PGA water immersion solution, mix well, pour 2L / m again after 1.5h 2 Water, mix well, pour the second time 1.5L / m after 1h 2 Water; the moisture content of the covering soil is 63%. Use lime to mix into the covering soil according to the ratio of 5% (mass ratio, the same below) of the covering soil, so as to increase and stabilize the pH at 7.5.

[0027] (2) Feeding and covering soil: sow the bacteria of Agaricus bisporus to the compost (compost), cultivate at 25°C for 18 days, and the mycelium will be covered with the compost; the temperature will rise at this stage, and the temperature can be controlled by adjusting the wind speed of t...

Embodiment 3

[0033] (1) Cover soil improvement and sterilization: The cover soil composed of peat soil dug from the pond has been cultivated for a round of Agaricus bisporus (harvesting 2 crops of mushrooms). Use formaldehyde fumigation to sterilize the covering soil, then cover it with a film for 6 days, uncover the film, and let the formaldehyde disperse before use. Spray 3L / m 2 γ-PGA water immersion solution, mix well, pour 2L / m again after 1.5h 2 Water, mix well, pour the second time 2L / m after 2h 2Water; the moisture content of the covering soil is 65%. Use lime to mix into the covering soil according to the ratio of 6% (mass ratio, the same below) of the covering soil, so as to increase and stabilize the pH at 7.2.

[0034] (2) Feeding and covering soil: sow the bacteria of Agaricus bisporus to the compost (compost), cultivate at 25°C for 18 days, and the mycelium will be covered with the compost; the temperature will rise at this stage, and the temperature can be controlled by ad...

Abstract

The invention discloses a covering soil improvement method after culture of agaricus bisporus, including the steps of (1), rejecting and removing covering soil from the compost after reaping all agaricus bisporus and clearing residual bodies of agaricus bisporus, and transferring the separated covering soil to a cleaning area; (2), sterilizing the covering soil; (3) adding gamma-PGA to the covering soil, to be specific, watering the covering soil with 1.5-3 L / m<2> of gamma-PGA extraction solution and then uniformly mixing fully, watering the covering soil with 1.5-2 L / m<2> of water after 1-2 hours and then mixing uniformly fully, watering the covering soil with 1.5-2L / m<2> of water again after 1-2 hours, until reaching the initial water absorption capacity of the covering soil, while ensuring all moisture is absorbed by the covering soil completely, without any puddles or pondings formed. Without influence to quality and yield of agaricus bisporus, the method can prolong service cycleof the covering soil; the covering soil is added with the gamma-PGA extraction solution, and accordingly can be continued to be used for the next culture periods.

Description

technical field [0001] The invention relates to an improvement method for covering soil of Agaricus bisporus after cultivation, which prolongs the service period of covering soil without affecting the quality and yield of Agaricus bisporus. Background technique [0002] Agaricus bisporus, also known as white mushroom, mushroom, and sea mushroom, is the most widely cultivated, largest-scale, and most productive global edible fungus in the world. my country is a big producer of Agaricus bisporus, and Agaricus bisporus is one of the main varieties of edible fungi produced in my country, and its export volume ranks first in the world. [0003] Covering soil is a substance covering the mycelium of mushrooms, which can play the role of transferring nutrients and water between the cultivation material and mushrooms. The covering soil has the function of buffering water, which can quickly absorb water and release it slowly; secondly, due to its unique structure, the covering soil a...
