The latest technique and method tutorial for growing Polyporus umbellatus

Polyporus umbellatus, also known as Zhufuling and Zhulingzhi, is a medicinal fungus of the genus Grifola in the family Polyporaceae, order Aphyllophorales. Its young fruiting bodies are edible and delicious, and it is also a famous traditional Chinese medicine with a diuretic effect for treating edema. So how should Polyporus umbellatus be grown? Let's take a look together.

1. Site selection

The most important thing in artificial cultivation of Polyporus umbellatus is site selection, which must take into account terrain, topography, vegetation, soil and other aspects. Polyporus umbellatus is suitable for growing in areas at an altitude of 300-1500 m, preferably on semi-sunny and semi-shady slopes. For vegetation, shrub species such as oak, birch, maple, elm, willow and poplar are preferable, and for soil, sandy clay rich in humus is preferable, with the soil being slightly acidic. Saline-alkali land and peat land are not suitable for planting. After selecting the site, dig holes along the slope, with a plant-row spacing of 30×50 cm between holes, and drainage ditches are also needed. The holes are generally 1 m long, 70 cm wide and 15 cm deep.

2. Material preparation

First, choose good fungus wood. Tree species such as linden, birch and maple are suitable; these species have thick, high-quality bark, support the growing environment of Armillaria and are rich in nutrients, providing a lasting nutrient supply for the fungal inoculum and helping achieve high yields. Also prepare Polyporus umbellatus sclerotia and Armillaria inoculum. For the inoculum, choose high-quality inoculum with thick hyphae, a reticular mycorrhiza on the surface and strong hyphal sprouting ability, so as to obtain high-yielding, high-quality Polyporus umbellatus.

3. Propagation method

First spread a layer of leaves 2-3 cm thick at the bottom of the hole, break the Armillaria into small pieces and scatter them evenly on the leaves, then scatter Polyporus umbellatus growth hormone on the leaves. Finally place the fungus wood on the leaves; the fungus wood should have a certain spacing, preferably 3-5 cm, and then fill the gaps with the mixture. Break the Polyporus umbellatus sclerotia into small pieces and place them evenly on both sides of the fungus wood, cover with another layer of leaves, cover the leaves with a 10 cm thick layer of humus soil, and then cover with leaves.

4. Management

The key point in cultivating Polyporus umbellatus is temperature. At a depth of 10 cm, Polyporus umbellatus can germinate when the ground temperature is 10°C; after germination it grows fastest at 18-22°C; once the temperature exceeds 28°C growth is slow, and below 9°C or above 30°C growth stops. Therefore, the most important thing in management is temperature, and the ground temperature must be well controlled. Other management is relatively simple: no fertilization, no weeding, just let it grow naturally.
