Introduction to the methods of germination and sowing of Gastrodia mushroom spawn
1. Types of germination fungi The germination fungi of Gastrodia seeds reported so far all belong to 4 species of fungi in the Tricholomataceae family, Mycena genus. Their names are: first, Mycena osmarioides; second, Mycena orchidicola; third, Mycena dendrobii; fourth, Mycena anoectochila. In 1999, we isolated and cultured another type of fungus for Gastrodia seed germination, which is Trametes lactinea of the Polyporaceae family. This fungus is superior to the above four fungi in production and application during the higher temperature season. 2. Production technology of germination fungi Isolation and culture of the mother spawn of germination fungi: in Gastrodia cultivation sites

What are the excellent tea plant varieties? Introduction to common varieties
Breeding and promoting excellent tea plant varieties is a fundamental measure for improving tea quality and yield and increasing the economic benefits of tea growing. A large amount of production practice and scientific research results prove that selecting excellent tea plant varieties has multiple effects in tea production: First, it can increase yield. Tea yield is determined by comprehensive factors such as the number and weight of buds and leaves per unit area, the growth speed of buds and leaves during the annual growth period (cyclicity), and the length of the vegetative growth period. Under the same conditions, different varieties have different yield factors, so yield

How to treat pica in pigs? Introduction to symptomatic treatment methods
Once pica occurs in pigs, they grow slowly, gradually become emaciated, and have rough skin and messy hair. If not treated in time, it will affect the growth and development of the pigs, and young pigs that have not yet grown may become stunted pigs and stop growing. When such a situation is encountered, the pigs' feed should be adjusted in time and symptomatic treatment should be given. 1. If pigs eat coal cinders and soil, various trace elements such as iron, manganese, zinc, and magnesium should be supplemented. 2. If pigs eat pig manure, vitamin B12 should be given orally or by intramuscular injection, once a day, 500-1500 milliliters each time, for 3

Detailed Introduction to the Correct Mixing Method for Chicken Feed
When using feed, it is required that every portion of the feed consumed by the chickens contains balanced and identical nutrients; otherwise, the flock will suffer from malnutrition, deficiency diseases, or poisoning. Even if your diet formula is very scientific and the feeding conditions are very good, you still cannot achieve satisfactory feeding results. Therefore, the feed must be mixed evenly to meet the nutritional needs of the chickens. There are two methods of feed mixing: mechanical mixing and manual mixing. As long as they are used properly, both can achieve satisfactory results. Mechanical mixing: use a mixer. Commonly used mixers

Introduction to the Biological Characteristics of the Topmouth Culter (Culter alburnus) from the Yangtze River
The topmouth culter, commonly known in Guangdong as "Yangtze Heshun," in the middle reaches of the Yangtze as "qiaobai" or "white fish," and in the lower reaches of the Yangtze as "Taihu white fish." In recent years, many people in our province have passed off the bigeye culter, i.e. the "Pearl River Heshun," as "Yangtze Heshun" to sell to farmers, with the result that even after four years of intensive culture they could not reach the market size of 8 liang to 1 jin. Since last year, Hainan culter and qingshao culter have been passed off as "Yangtze Heshun"; although they grow somewhat faster than the bigeye culter, they are slower than the genuine topmouth culter, and it is very difficult to raise them to a market size of over 1 kg
