Problems solved by technology

But unfortunately, in the current liquid culture technology, the culture medium is all put into the culture tank, and the culture medium contains insoluble solids, which release enzymes in the liquid culture process, causing the culture liquid to have peculiar smell, and causing mycelium, insoluble solids It is difficult to separate from the culture medium; in addition, most of Ganoderma lucidum cultivation adopts the methods of wood chip cultivation and basswood cultivation, which need to consume a large amount of wood resources, which is not conducive to the protection of the ecological environment. The large-scale development of wood chip cultivation and basswood cultivation edible fungus production is subject to Forest resources are limited, so the "bacteria forest contradiction" is becoming more and more prominent

Embodiment 1

[0018] 1. Preparation method of compost

[0019] (1) Weighing: the prepared raw materials are weighed according to the proportion determined by the formula; wherein, the used tea oil tree residue is pulverized with a pulverizer.

[0020] (2) Mixing material: when preparing, tea oil tree residue and water-insoluble auxiliary materials bran, rice bran, wood chips, etc. are evenly stirred, and water-soluble substances such as sugar and starch are prepared into an aqueous solution and added. Stir evenly, and turn the pile several times to allow the compost to fully absorb water.

[0021] (3) Adjust the water content: on sunny days, the evaporation of water is large, so the water should be slightly higher, and on cloudy days, it should be lower; the mixing site has strong water absorption, so the water should be increased, and vice versa. When mixing with tea oil tree dregs culture material, grab a handful of the mixed raw materials with your hands, hold it tightly, water can seep...

Embodiment 2

[0032] Comparison of the growth speed of ganoderma lucidum with different formula nutrient bases. In the nutrient bases commonly used in this field, the conventional dosage range of sugar is 0.5-3%, and the conventional dosage range of gypsum is 1-3%. For the convenience of comparison, in the following The consumption of fixed sugar and gypsum is 1% in the embodiment.

[0033] Test conditions: cultivation base temperature: 21-25°C, humidity 82%-93%;

[0034] The formulas for planting medicinal Ganoderma lucidum are as follows (the ratio of each raw material is weight percentage), and the preparation method is referred to Example 1.

[0035] Formula 1: wood chips 75%, wheat bran 18%, corn flour 5%, sugar 1%, gypsum 1%;

[0036] Formula 2: Camellia oil tree residue 5%, sawdust 70%, wheat bran 18%, corn flour 5%, sugar 1%, gypsum 1%;

[0037] Formula 3: 20% tea oil tree residue, 55% sawdust, 18% wheat bran, 5% corn flour, 1% sugar, 1% gypsum;

[0038] Formula 4: 30% tea oil tr...

Embodiment 3

[0052] Bacteriostasis test of culture medium

[0053] The bacteriostasis effect of culture medium 1 to medium 8 in Example 2 on Escherichia coli, Staphylococcus aureus and Candida albicans was measured by disc agar diffusion method, see Table 5.

[0054] Table 3 antibacterial effect

[0055]

[0056]

[0057] Note: × indicates no antibacterial effect, √ indicates antibacterial effect.

Abstract

The invention provides a nutrient medium for planting ganoderma lucidum, the invention aims at providing a nutrient medium capable of facilitating the production of medical ganoderma lucidum with high quality and high value and protecting the forest resources so as to solve the increasingly serious fungus and forest conflict problem in the development of medical ganoderma lucidum industry; the technical scheme is as follows: the nutrient medium comprises the following raw materials in percentage by weight: 5-90% of tea tree residue, 0-70% of saw dust, 8-18% of wheat bran, 0-5% of corn flour, 1% of sugar and 1% of gypsum; and the invention belongs to the technical field of biological medium.

Description

technical field [0001] The invention relates to a nutrient base, in particular to a nutrient base for growing ganoderma lucidum, and belongs to the technical field of biological culture medium. Background technique [0002] Today, when land, food and other resources are becoming increasingly scarce, the ecological environment is deteriorating, and human health awareness is gradually increasing, fungi foods that can convert crude fiber into high-quality bacterial protein and have unique health care functions for the human body are becoming more and more popular. The edible fungus industry It has become a model of green, environmental protection, efficient and circular agriculture. [0003] So far, Ganoderma lucidum preparations mostly use fruiting bodies or solid cultured mycelia as raw materials, which have a long production cycle and are easily polluted by the environment, which of course affects their quality. The application of liquid culture technology in this field has...
