Key Points and Management Methods of Polyporus umbellatus Cultivation

Polyporus umbellatus, also known as Zhu Fuling or Zhu Lingzhi, is a medicinal fungus of the genus Grifola in the family Polyporaceae of the order Polyporales. Its fruiting bodies are edible when young and have a delicious flavor. It is also a well-known traditional Chinese medicine with a diuretic effect for treating edema. So how should Polyporus umbellatus be cultivated? Let's take a look.

1. Site Selection

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

2. Material Preparation

First, select good fungus wood, preferably tree species such as basswood, birch and maple. These species have thick bark, good quality, and can support the growth environment of Armillaria mellea. They are also rich in nutrients, can provide a lasting nutrient supply for the fungal inoculum, and are conducive to high yield. Also prepare Polyporus umbellatus sclerotium Armillaria mellea inoculum. The inoculum should be selected as high-quality inoculum with thick mycelium, a reticular mycorrhiza on the surface, and strong mycelial sprouting ability, so as to obtain high-yield and high-quality Polyporus umbellatus.

3. Propagation Method

First spread a 2-3 cm thick layer of leaves at the bottom of the pit, break the Armillaria mellea into small pieces and evenly scatter them on the leaves, then scatter Polyporus umbellatus growth hormone on the leaves. Finally, place the fungus wood on the leaves, with a certain spacing between the fungus wood pieces, preferably 3-5 cm, and then fill the gaps with the mixture. Break the Polyporus umbellatus inoculum into small pieces and evenly place them on both sides of the fungus wood, then cover with a 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. Polyporus umbellatus can germinate when the ground temperature at a depth of 10 cm is 10 degrees, and after germination it grows fastest at 18-22 degrees. Once the temperature exceeds 28 degrees, growth slows down, and below 9 degrees or above 30 degrees, 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.
