Full Analysis of the Key Points of Stropharia rugosoannulata Cultivation Techniques

Stropharia rugosoannulata is a wild edible mushroom that lives symbiotically with tree roots. Because of its delicious flavor, it is deeply loved by people, so what exactly are the Stropharia rugosoannulata cultivation techniques?

1. Basic Introduction to Stropharia rugosoannulata

Stropharia rugosoannulata is a wild edible mushroom of the family Tricholomataceae and the genus Tricholoma, with the scientific name Stropharia rugosoannulata. In recent years, artificial cultivation has succeeded and begun to be promoted and applied. This mushroom is a new mushroom species recommended by the Food and Agriculture Organization of the United Nations to developing countries, and is also one of the top ten varieties on the international mushroom trading market.

The artificially cultivated Stropharia rugosoannulata is rich in nutrients and has a strong aroma that lingers on the lips and teeth, comparable to wild matsutake. It is rich in a variety of essential amino acids and vitamins for the human body, containing all the amino acids essential to the human body plus other amino acids, 17 kinds in total.

2. Stropharia rugosoannulata Cultivation Techniques

1. Preparing the culture medium

Select rice straw, rice husks, sawdust, etc., mix and ferment them to make a culture medium, and use it for cultivation after it has cooled.

The culture medium formulas are:

(1) 90% rice straw, 10% rice husks;

(2) 80% rice straw, 20% sawdust;

(3) 40% rice straw, 40% corn stalks, 10% rice husks.

Before sowing, the rice straw and stalks need to be soaked in water for 2 days, or thoroughly watered after the beds are laid out. In hot weather, the raw materials should undergo 2 to 3 days of pre-stack fermentation, and after turning the pile to release heat, they can be used for cultivation. The moisture content of the culture material should reach 70% to 75%.

2. Sowing

Choose a suitable planting site, carry out land preparation and disinfection before planting, and then sow at a certain spacing.

The site should preferably be chosen close to a water source, with convenient drainage, sheltered from wind, facing the sun, and with partial shade. It is best to plant on fertile loam soil that contains humus and is loose, which is conducive to early fruiting and increased yield.

Dig drainage ditches around the cultivation site to prevent water accumulation after rain. After clearing weeds from the plot, use a root tiller to till the roots to facilitate bed making. The bed width is 45-50 cm and the row width is 60-80 cm.

Use winter fallow fields for open-field cultivation or plastic greenhouses for facility cultivation. To create a semi-shaded ecological environment for the mushroom, a layer of plastic shade netting can be added on top, or climbing plants can be grown for appropriate shading, or straw curtains can be added to create a semi-shaded, moisture-retaining, and heat-preserving environment. Carry out ventilation management according to climate changes and fruiting conditions.

After land preparation is completed, splash 1% tea seed cake water or phoxim to kill insects and prevent pest damage. If a mountain area is chosen as the mushroom yard, ant-killing agents such as mirex and termite powder must be spread to eliminate ants.

Then spread a layer of soaked and treated stalks 20 cm thick in the bed, no more than 30 cm thick and no less than 20 cm, forming a turtle-back-shaped bed, with an 80 cm walking ditch left between beds. Press the stalks flat and firm, then spread a layer of pre-moistened rice husks 5 cm thick on the stalks, break the spawn into pieces the size of eggs and place them on the rice husks for sowing, using plum-blossom-shaped or triangular dibbling, at a spacing of 10-12 cm.

Use 10-15 kg of stalks per square meter, and 0.6-0.7 kg of spawn.

3. Other management

During the growth period of Stropharia rugosoannulata, temperature and humidity management also need to be done well, and after maturity it should be harvested and processed in a timely manner.

When the material temperature rises above 30°C, uncover the film for ventilation, and spray cold water on the bed surface to lower the temperature. When the bed surface is dry, water should also be sprayed to retain moisture. The requirement is to use mist water so that the casing soil layer is moistened while the water does not enter the material. When the temperature is below 10°C and on rainy days, the film should be covered.
