Detailed explanation of cultivation techniques of Ganoderma lucidum in 2019!

Ganoderma lucidum is a typical representative of "homology of medicine and food". At present, it can be cultivated artificially, and the cultivation techniques of Ganoderma lucidum have become more and more perfect. For those who want to try to grow Ganoderma lucidum in 2019, do not miss the following cultivation techniques of Ganoderma lucidum!

Ganoderma lucidum cultivation is basically divided into solid and liquid cultivation methods, and then we will learn more about how to operate.

1. Solid cultivation techniques of Ganoderma lucidum

In the solid culture and cultivation of Ganoderma lucidum, Ganoderma lucidum is mainly cultivated by Linden.

1. Brief introduction of the method

To imitate wild cultivation of Linden, the mother strains of Ganoderma lucidum with pure quality and strong vitality must be separated and selected, then inoculated on the hardwood sawed into 15-20cm long and diameter 6-15cm, and then cultivated on the hotbed.

2. Cultivation cycle

Linden cultivated Ganoderma lucidum takes about 9 months to 1 year from breeding to harvesting. When it matures, the umbrella piece will be reddish brown, and the bottom of the cap will be beige. This is the period with the most active ingredients, and should be harvested immediately. Otherwise, after the spore powder is ejected and the umbrella piece is lignified (for example, wild Ganoderma lucidum has this phenomenon), the active ingredients will be lost.

3. Cultivation characteristics

Linden cultivated Ganoderma lucidum after drying, the texture of Ganoderma lucidum is thick, hard, nutritious and effective ingredients are complete. This cultivation method is better than using sawdust or liquid culture, easy to control the quality, not easy to be contaminated. The quality of cultivated Ganoderma lucidum is the best, and its cost is relatively high.

2. Liquid cultivation techniques of Ganoderma lucidum

1. Brief introduction of the method

The basic process of submerged fermentation culture of Ganoderma lucidum fungi is as follows:

Production of → spores to prepare → seeds to prepare → fermentation → fermentation products (extraction, purification) → products.

In the process of liquid submerged fermentation, there are three main factors that affect the production cycle, production level and production cost.

(1) producing strain

(2) composition of culture medium

(3) fermentation process parameters.

2. Factor analysis.

The composition of deep culture medium and its ratio not only affect the growth, morphology and structure of Ganoderma lucidum mycelium to a great extent, but also have a great influence on the production and subsequent extraction of metabolites. Therefore, it is very important to choose a suitable medium.

Ganoderma lucidum submerged fermentation selected glucose and corn meal as comprehensive carbon source, yeast extract and soybean powder as comprehensive nitrogen source, and added a certain amount of VB1.

On the one hand, corn meal can reduce the cost, on the other hand, it can increase the viscosity of the culture medium to increase the fungus point. Soybean powder can also reduce the production cost, and as a compound organic nitrogen source, it is more conducive to the use of bacteria.

Generally speaking, Linden cultivation of Ganoderma lucidum has a long growth cycle (more than 2 Mel 3 months), which is greatly affected by the environment, low yield, unstable quality and high production cost, while liquid cultivation of Ganoderma lucidum can reduce the cultivation cycle, but it is more technical.
