High-yield planting techniques of Polyporus umbellatus

Polyporus umbellatus, also known as wild boar dung, turnip peach, powder Polyporus umbellatus, etc., is the sclerotia of Polyporus umbellatus, which is beneficial to urination and wetting. In recent years, it has been found to have anticancer effect, which is widely distributed in our country. Hebei, Shanxi, Henan, Liaoning, Jilin, Hubei, Sichuan, Yunnan, Guizhou, Shaanxi, Gansu and other provinces are produced, let's take a look at Polyporus umbellate high-yield planting technology!

Growth characteristics

Polyporus umbellatus likes fertile, moist, humus-rich and well-drained sprouting slopes to grow at 5 cm below the ground temperature of 8: 9 ℃, and the best growth is at 15-20 ℃. The hyphae stop growing at 25-30 ℃, go into short-term dormancy or grow fruiting bodies, and pass through the adverse environment to reproduce spores. In late autumn and early winter, 5 cm below the ground, the temperature is below 8 ℃ and then enter the winter dormancy period. April to June and September to October are the active growth periods of Polyporus umbellatus mycelium.

Preparation of cultivation materials

Polyporus umbellatus planting selected oak, birch, maple, maple, red poplar, mulberry, willow and other hard broad-leaved trees forged, about 10 cm in diameter, sawed into a length of 60 cm, drying for 15 days, so that the water content of about 70%, and then every 3 to 5 cm, according to the shape of three rows of holes, the Polyporus umbellate strain filled the hole.

Land selection and preparation

Polyporus umbellatus should choose sandy loam with moist, good permeability and slightly acidic soil water content of 30% to 50%. The slope direction is the Eryang slope in the southwest or northwest direction, and the slope is between 20 and 30 degrees. After the ground is selected, the cellar is cultivated along the slope, with a depth of 50 cm, length and width of 70 cm each.

Cultivation time

The best cultivation time of Polyporus umbellatus is from March to April in spring or from July to August in autumn, when Polyporus umbellatus is going through the dormant period and entering the growth period, Armillaria mellea is also in the growth period, and the two can establish a good symbiotic relationship with each other.

Cellar cultivation

Dig the bottom of the pit 7 cm 10 cm, put it into the humus soil of 1 hammer 3, flatten it, spread a layer of soaked dry tussah leaves, and place the Polyporus umbellata rod on the leaves with a spacing of 6 cm 10 cm. Put some Armillaria mellea branches between the sticks, and then sprinkle the cultivated species of Armillaria mellea on the leaf branches. no, no, no. Stick Polyporus umbellatus next to the stick of Armillaria mellea. Then fill the humus, gently press it, leaving no space, moderate tightness, do not press too hard. Finally, cover the fine soil 10cm and 15cm, cover the dead branches and leaves on the top of the cellar, slightly above the ground, so that the back of the tortoise, in order to facilitate drainage.

Post-planting management

Polyporus umbellatus is cultivated without fertilization or weeding to keep it wild, but it is necessary to keep the pit soil moist properly to prevent human and animal trampling and rodent damage. Do not look at it arbitrarily, so as not to destroy the symbiotic relationship between the two.

Harvest and processing

Polyporus umbellatus perennial habit, the yield is not high in one or two years, three or four years of cultivation is the vigorous period of reproduction. During the harvest, we should pay attention to the sclerotia in the surface soil layer, which can be harvested all the year round, especially in summer and autumn. The hard color of the substantia nigra is called the old nucleus, which is the commercial Polyporus umbellatus, that is, the first generation and the second generation. The sclerotia of Polyporus umbellatus should be washed and cleaned during harvest, and then dried in the sun. After drying, it can be shipped and sold, packed in sacks or bamboo seeds, and stored in a dry place.
