Problems solved by technology

[0004] Loam soil is used as a covering soil material, although it has the advantages of easy availability of materials and low cost, but for the cultivation of Agaricus bisporus, it has low water holding capacity, too compact aggregate structure, poor air permeability, and the microbial growth required for the growth of Agaricus bisporus. The unfavorable factors of the low number of groups lead to the failure of the mycelia of Agaricus bisporus to grow well, and the yield and quality of Agaricus bisporus are insufficient
[0005] Peat soil is used as a covering soil material, although its water holding capacity is better than that of loam soil, but its water holding capacity is still low, and the yield and quality of Agaricus bisporus are not the best

example 1

[0021] The Edible Fungi Research Office of China Agricultural University carried out a test on the cultivation of Agaricus bisporus covered with earthworm manure in the autumn of 2007. The specific steps include:

[0022] 1) Prepare vermicompost: select the vermicompost produced after cow dung is fully digested and absorbed by earthworms as the covering soil material;

[0023] 2) mixing vermicompost with loam or peat soil: after mixing, vermicompost accounts for 30% or 20% of the total weight respectively;

[0024] 3) After spreading the dung grass fermentation culture material (thickness is 15-18cm) on the Agaricus bisporus cultivation bed frame, mixed sowing and inoculation;

[0025] 4) 20 days after sowing, when the hyphae of Agaricus bisporus (purchased from the China Agricultural Microorganism Culture Collection Management Center or cultivated in your own laboratory) "feed" to about 2 / 3 of the depth (8-12cm), it can be covered with soil. If the material surface is relati...

example 2

[0031] Vermicompost is mixed with loam or peat soil: after mixing, the vermicompost accounts for 34% or 23% of the total weight respectively; other implementation method steps are the same as Example 1.

[0032] The Edible Fungus Research Office of China Agricultural University carried out a test on the cultivation of Agaricus bisporus covered with earthworm manure in the spring of 2008. The yield per unit area of ​​conventional cultivation (without adding earthworm manure) was 7.7kg / m 2 , the yield per unit area cultivated with earthworm dung is 9.9kg / m 2 , and the yield increase rate reached 29% compared with the conventional cultivation control. The number of water sprays in the whole cycle of conventional cultivation is 68 times, and the number of water sprays in the whole cycle of earthworm dung-covered cultivation is 46 times, and the number of water sprays reduced is 22 times.

example 3

[0034] After the vermicompost is evenly mixed with loam or peat soil, the vermicompost accounts for 26% or 17% of the total weight respectively; the steps of other implementation methods are the same as those in Example 1.

[0035] The Edible Fungus Research Office of China Agricultural University carried out a test on the cultivation of Agaricus bisporus covered with earthworm manure in the autumn of 2008. The output per unit area of ​​conventional cultivation (without adding earthworm manure) was 8.0kg / m 2 , the yield per unit area cultivated with earthworm dung is 9.9kg / m 2 , and the yield increase rate reached 24% compared with the conventional cultivation control. The number of water sprays in the whole cycle of conventional cultivation is 60 times, and the number of water sprays in the whole cycle of earthworm manure-covered cultivation is 43 times, and the number of water sprays in the whole cycle is reduced to 17 times.

Abstract

The invention discloses a method for cultivating the edible fungus by taking worm-cast as soil-covering material, which belongs to the technical field of edible fungus cultivation in the agricultural technology. The method comprises the following steps: firstly, the daily manure is selected and is fully digested and absorbed by earthworms to generate worm-cast as the soil-covering material, the worm-cast is evenly mixed with loam and soddy soil, the soil covering is performed when the filler absorption of the mycelium of the agaricus bisporus reaches 8 to 12 cm, water is prayed to keep the soil covering layer humid, finally, when the mycelium climbs to the surface of the soil covering layer, the ventilation is carried out, and the fruiting water is spouted to promote the formation of the anlage of the agaricus bisporus. The invention takes account of the granular structure, the air permeability and the microorganisms of the soil-covering material from the aspect of the water-retaining capacity of the soil-covering material as well as the cost of the soil-covering material, solves the problem that the soil-covering material of the current agaricus bisporus is inappropriate and promotes the positive development of the agaricus bisporus industry.

Description

technical field [0001] The invention relates to a method for cultivating edible fungi using vermicompost as a soil covering material, and belongs to the technical field of edible fungus cultivation in agricultural technology. Background technique [0002] The cultivation of Agaricus bisporus in my country generally uses loam as the covering soil material, and the maximum water holding capacity of the loam soil is only 0.36kg water / kg loam soil; a small number of industrialized cultivation of Agaricus bisporus in China uses peat soil as the covering soil material, and its maximum water holding capacity is 0.84kg water / kg kg of peat soil; the peat bog mixture used in the factory cultivation of Agaricus bisporus abroad is the covering soil material, and its maximum water holding capacity is 2.31kg of water / kg of peat bog mixture. The soil covering material of Agaricus bisporus is one of the keys related to the high-quality cultivation of Agaricus bisporus, whether the water hold...
