The collection and processing of fungus Chinese medicine

Harvesting

Bacteria are mostly fruit bodies and sclerotia of Ascomycetes and Basidiomycetes. The rational harvesting of fungus Chinese medicine has a great relationship with its yield and quality. The climatic conditions in different regions are different, and the growth and development of fungus Chinese herbs are also different, so the harvest period is also different. Must grasp the growth and development of fungi Chinese medicine law, do not miss the opportunity to properly harvest. There are many kinds of fungus medicines and different varieties have different harvesting seasons. The general rule is:

Sub-entities The wild mushroom medicines that are used as fruiting bodies for their medicinal purposes grow more abundantly in the rainy seasons of July-August and should be harvested in time. Some glial bacteria such as black fungus begin to grow and harvest in May-June. Artificially cultivated mushrooms should be harvested at the peak of fruiting, and the amount of picking should be determined according to the growth density of the mushroom. Generally, it is necessary to pick more when it grows densely. Ma Boyi was harvested when the fruiting body was just mature, but the spores were dispersed too late; Cordyceps sinensis was excavated when the spores unearthed from the unsealed subtila were found in the early summer.

Sclerotia have a lot of fungus medicines to use sclerotium as medicine, such as wolfberry, swine cricket, Lei pill and so on. Most of the wild sclerotia are harvested in the spring or autumn. The artificially cultivated earthworms are in the spring of the second year after inoculation; pigs can be harvested in 4 to 5 years, and autumn is preferable.

Processing

After recovery of the mushroom-based Chinese herbal medicines, the soil, impurities, rot, and moth-eaten areas should be promptly removed and processed as soon as possible. Commonly used medicines for fungi only need to be dried.

Dry the fungus Chinese herbs directly on the mat, exposure to sunlight. Under conditions, shelves can be placed on the shelves, and the collected fresh bacteria that have been processed and treated are laid on the mats without overlapping to facilitate ventilation and drying. The drying method is simple and easy, the production cost is low, and energy is saved. However, the drying process is slow, takes a long time, and is susceptible to the weather. In particular, wet and rainy weather and prolonged drying time can greatly reduce the quality of the product.

Drying uses charcoal fire, electric oven, microwave or far-infrared heat source, ventilation equipment such as electric fans and exhaust fans to dry fungus Chinese medicine in the baking room. When baking, the temperature should not be too high, the initial temperature is generally 35 ~ 45 °C, and finally reached 60 ~ 70 °C, does not exceed 80 °C. In a certain period of time, draw out moist air to speed up the drying. Practice has confirmed that the use of infrared variable temperature hygroscopic and dry advanced practical technology, high efficiency, low energy consumption, good quality, it is worth promoting.

Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
