Planting and cultivation techniques of Polyporus umbellatus

1. Land selection and preparation. In the original broad-leaved forest, mixed forest or secondary forest cultivation, such as birch, oak, maple, tussah, willow and other forests, do not plant in the coniferous forest. It is better to choose the elevation of 1000-2000 meters, the terrain of shady slope or semi-sunny slope, the slope of 15-45 degrees, the humus soil layer of more than 20 cm, and the slightly acidic soil water content of about 40%. Saline-alkali land and peat land are not suitable for cultivation. After selecting the land, the length of the pit (also known as the cellar) is 70 cm, the width is 60 cm, the depth of the nest is 18-20 cm, and the distance is 50 cm.

2. Materials per square metre. 3 bottles of Polyporus umbellatus, 3 bottles of Armillaria mellea and a certain amount of wood sticks (5cm in diameter and 50cm in length), mixture of Polyporus umbellatus auxin, broad-leaved leaves, leaves and humus soil.

3. Lay leaves at the bottom of the nest. Spread the leaves with a thickness of 2 cm to 3 cm, break the Armillaria mellea into small pieces of 1 cm and 2 cm and spread it evenly on the leaves, then sprinkle Polyporus umbellata auxin evenly on the leaves, put the fungus (wooden stick) on the leaves that have been sprinkled with Armillaria mellea, the distance between the fungus is about 3 cm, fill the spacing with the mixture, break the Polyporus into blocks of about 2 cm, and evenly place on both sides and ends of the fungus. Then cover about 3 cm of leaves, cover the leaves with about 10 cm of humus soil, and then cover the top of the nest with leaves.

The key to the cultivation of Polyporus umbellatus lies in the quality of Polyporus umbellatus. The hyphae of high quality Polyporus umbellatus were stout, with reticulated mycorrhiza on the surface, strong germination ability and high success rate. The hyphae were planted for 5 days when the ground temperature was above 15 ℃, and the hyphae extended to the soil for 20-30 days.

4. Temperature. Polyporus umbellatus can germinate at a depth of 10 cm at an average ground temperature of 9.5 ℃. It grows fastest at 18-22 ℃, grows slowly over 28 ℃, stops growing below 9 ℃ and stops growing over 30 ℃.

5. Harvest and processing. The mature period of sowing with pure Polyporus umbellatus seed is about 3 years (5 ~ 6 years in the old method). When the color of Polyporus umbellata is hard (called old kernel), it can be harvested in April ~ May in spring or July ~ September in autumn.

Remove impurities from the sclerotia of Polyporus umbellatus harvested, rinse clean and dry in the sun, that is, commercial medicinal materials. Put it in sacks or bamboo baskets and store it in a dry and ventilated place for sale. Polyporus umbellatus skin is jet-black luster, weight, solid, section white or yellow is the superior product.
