Poria cocos planting technology how to cultivate Poria cocos planting time

Presumably everyone is already familiar with Poria cocos, and they often eat Poria cocos cakes and other foods in their daily life. In fact, Poria cocos is also a common traditional Chinese medicine, which can strengthen the spleen, treat qi deficiency, and play a good role in nourishing the heart and calming the mind. However, many people are still very strange to its planting technology, let's have a look at it together.

Planting technology of Poria cocos

1. Nutrition: potato juice, pine sawdust and pine chips are commonly used as comprehensive nutrition sources in the process of pure culture of Poria cocos mycelia, or glucose, sucrose and rice bran are used as carbon sources, amino acids and peptone are used as nitrogen sources. Potassium dihydrogen phosphate, magnesium sulfate, magnesium nitrate, ammonium nitrate and cooked gypsum are used as mineral sources. In order to ensure the need of various mineral elements in Poria cocos mycelium, natural water is used instead of distilled water when preparing culture medium.

2. Temperature: the mycelium can grow at 10-35 ℃, and the optimum temperature is 23-28 ℃. When the mycelium is higher than 35 ℃, the mycelium is easy to aging, the duration is long or the temperature is too high, it will cause death. The mycelia grow slowly below 20 ℃, and the bacteria can be preserved at low temperature of 0-4 ℃.

3. Humidity: the growth and development of mycelium and sclerotia require soil water content of about 20%, and the formation of fruiting body requires an air relative humidity of 70-85%.

4. Ph value: Poria cocos growing soil PH3-7, cultivation soil PH4-6 is better.

How to cultivate Poria cocos

1. Select the cultivation site

Most of the producing areas choose the hillside with an altitude of 600-900 meters and cultivate sandy soil with sunny leeward, neutral or slightly acidic and good drainage.

2. Preparing materials

Can be carried out in the early winter of the first year, when the pine is in the dormancy stage, low water content, not easy to peel, conducive to strain growth and extension. Trees should be cut down big and small, dense and thin. Cut and shave the branches and cut 3-10 pieces of bark according to the thickness of the pine. The cutting surface is 3 cm wide and 0.5 cm deep into the xylem, making the pine wood easy to dry and flow out turpentine. The unpeeled skin is called tendon, which is convenient for silk to spread and grow. When the pine fracture stops draining grease, the sawing length is 65-85 cm. Fine wood can be longer, but the maximum length is no more than 90 centimeters. After sawing, the sawed wood is transported to the ventilated and transparent place near the cultivation site to be stacked in the shape of a "well".

3. Prepare the strain

The strain is also called introduction, and there are three kinds of mycelium, meat and wood, and now mycelium is often used. The mycelium is the mycelium of Poria cocos cultured artificially, and the mother mycelium is obtained by tissue isolation; the meat is introduced into the slices of fresh Poria cocos; the wood is the wood inoculated by meat, with yellow and white, obvious mycelium under the skin and fragrance of Poria cocos.

4. Mycelium induction inoculation

Choose a sunny day to put the wood into the cellar, each cellar 2-3 or more, thick and thin, layer by layer. During inoculation, the cultivated species were inverted and inserted at the tip of the fine wood, and the fine wood was surrounded by the thick wood, so that the hyphae could spread from the fine wood to the thick wood. Cover 3 cm of soil in time after inoculation. The cultivated species can also be taken out of the bottle and connected to the saw at the upper end of the wood, not too scattered; the strain should be close to the wood, and some wood chips and leaves can be covered to protect the strain, and then covered with soil.

Poria cocos planting time

Poria cocos are inoculated in spring and autumn. Spring planting is carried out from Qingming Festival to the Beginning of Summer. The temperature in the south, southeast and west of Guangxi rose earlier, and it was more suitable to be vaccinated before and after the Qingming Festival, while in the north and northwest of Guangxi, it was suitable to be vaccinated before and after the Beginning of Summer. There is little difference in temperature in autumn, and Poria cocos can be vaccinated before and after the Beginning of Autumn.

Poria cocos cultivation is to breed with bacteria or fresh Polyporus cocos (sclerotia) as "seeds". The strain is disinfected with small pine segments bottled (plastic), added with an appropriate amount of culture medium, connected with the original culture of Poria cocos, and the white exuberant mycelium grows in the bottle. On the other hand, the propagation of fresh Ling was made of thin skin and tender reddish brown, which was cut into pieces with skin and weight of 0.1-0.15kg with bamboo knife as the breeding material for inoculation.

How to harvest and process Poria cocos

1. Harvest

10-12 months after inoculation, cracks appeared in the soil of Poria cocos cultivation site, and the color of sclerotia epidermis could be observed by peeling off the soil to observe the color of sclerotia epidermis. When the skin of Poria cocos was yellowish brown, it could be harvested and dug immediately. After digging out, brush off the sediment, pile it indoors and arrange it layer by layer. Add a layer of straw on the bottom and the surface to make it sweat. Turn once every 3 days, and when the water vapor dries and the skin wrinkles, the skin can be peeled off, that is, Poria cocos skin.

2. Processing

Cut the peeled Poria cocos into thin and uniform slices, the pink ones are red Poria cocos, the white ones are Poria cocos slices, and the center with wood heart is Ling God. Also can not slice, water evaporation and then dry for a cocos, every 100 kilograms of fresh Poria cocos can be processed into 60 kilograms of cocos.

Poria cocos has high medicinal value and is widely used in the fields of medicine and health care. It is a longevity treasure that people always admire. Although there are many people planting Poria cocos at present, the market is still in short supply, and the market prospect is very broad.
