Problems solved by technology

Due to the weak ability of Flammulina velutipes to decompose lignin and cellulose, this formula with wood chips as the main nutrient source is not conducive to the nutritional requirements of Flammulina velutipes growth
The ratio of cottonseed husks in this formula reaches 30-40%. Because cottonseed husks are covered with lint, it is difficult to bottle with a mechanical stirring bottling machine, which affects the quality of bottling.
In addition, the overall formula also has an unreasonable nutrient ratio, which is not conducive to the growth of Flammulina velutipes
[0003] The preparation method of the culture medium in the prior art is to simply pulverize the raw materials, the particle size is relatively large, and then add water to mix and stir. Extended period, quality decline and other issues

Embodiment 1

[0016] Embodiment 1: raw materials were weighed according to the following weight ratios: 39 parts of corncobs, 38 parts of rice bran, 8 parts of bran, 5 parts of cottonseed hulls, 1 part of shell fossils, 4 parts of soybean hulls, and 5 parts of brewer's grains. (a) each raw material that weighs is pulverized into the particle below 4mm respectively; (b) the corncob that weighs and pulverizes, cottonseed shell particle add water and stir 20 minutes, to compost moisture content is 40%, stir again 25 minutes; (c) add the weighed and crushed rice bran, shellfish fossils, soybean hulls, and brewer's grains and stir for 30 minutes, add water until the water content of the compost is 64%, and stir for another 20 minutes; (d) culture the stirred Base mix into planter bottles.

Embodiment 2

[0017] Example 2: raw materials were weighed according to the following weight ratios: 30 parts of corn cobs, 30 parts of rice bran, 9 parts of bran, 2 parts of cottonseed hulls, 1.2 parts of shellfish fossils, 5 parts of soybean hulls, and 4 parts of brewer's grains. (a) each raw material that weighs is pulverized into the particle below 4mm respectively; (b) the corn cob that weighs and pulverizes, cottonseed hull particle add water and stir 15 minutes, to culture material moisture content is 42%, stir again 28 minutes; (c) add weighed and crushed rice bran, shellfish fossils, soybean hulls, and brewer's grains and stir for 26 minutes, add water until the water content of the compost is 63%, and stir for another 25 minutes; (d) culture the stirred Base mix into planter bottles.

Embodiment 3

[0018] Example 3: raw materials were weighed according to the following weight ratios: 40 parts of corncobs, 30 parts of rice bran, 6 parts of bran, 4 parts of cottonseed hulls, 0.8 parts of shellfish fossils, 3 parts of soybean hulls, and 6 parts of brewer's grains. (a) each raw material that weighs is pulverized into the particle below 4mm respectively; (b) the corncob that weighs and pulverizes, cottonseed shell particle add water and stir for 12 minutes, until the water content of compost is 43%, stir again for 30 minutes minutes; (c) add the weighed and crushed rice bran, shellfish fossils, soybean hulls, and brewer's grains and stir for 32 minutes, add water until the water content of the compost is 64%, and stir for another 22 minutes; (d) culture the stirred Base mix into planter bottles.

Abstract

The invention discloses a culture medium of needle mushroom, comprising the following raw materials in parts by weight: 33-45 parts of corn cob, 32-44 parts of rice bran, 6-10 parts of bran coat, 3-7 parts of cotton seed hull, 0.5-1.5 parts of shell fossil, 2-6 parts of soy hull, and 3-7 parts of bear lee. All raw materials are waster materials of agricultural production, are favorable to promoting the recycling of agricultural resources, and the culture medium has rich sources of raw materials, low price and rich nutrition; the pH value of the culture medium can be regulated with shell fossil and bear lee, thereby providing good nutrient growth environment for needle mushroom and having obvious yield increasing effect.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a culture medium and a preparation method of Flammulina velutipes. Background technique [0002] The growth and development of Flammulina velutipes requires nutrients such as carbon sources, nitrogen sources, minerals, and vitamins. In the production of Flammulina velutipes, raw materials such as cottonseed hulls, corncobs, bran, sawdust, and lime are often used in the prior art to prepare solid medium for growth of Flammulina velutipes source of nutrition. Disclosed a kind of culture medium of Flammulina velutipes as Chinese invention patent application public specification CN1879463, the formula of its raw material and weight ratio are as follows: cottonseed hull 30~40%, operation crumb 30~40%, bran 25~30%, calcium carbonate 1%. Because the ability of Flammulina velutipes to decompose lignin and cellulose is weak, this formula with sawdust as the...
