What mushroom production strains are used in China? Introduction to the main varieties
Since China began developing mushroom production, about several dozen strains have been used for cultivation, among which some were introduced from abroad and some were bred domestically. In the past, more strains were introduced, but as China's mushroom breeding work has deepened, the number of introduced strains has gradually decreased. At present, the most widely used strain in China is Ag2796, bred by the Fujian Provincial Institute of Light Industry, as well as As3003; introduced strains include S130, F56, and others.

Introduction to Xianghongmi, a New Semi-Dwarf Pear Strain
Xianghongmi was bred by the Chinese Academy of Fruit Tree Research from a cross between Aixiang as the female parent and Hexincun as the male parent. In Xingcheng, Liaoning, the fruit ripens in mid-to-late August, with a development period of i00d (days). The fruit is round, with an average single-fruit weight of 175g and a maximum of 240g. The background color of the fruit is yellow-green, with a purplish-red blush on the sunny side. The flesh is milky white and fine-textured; after ripening, the flesh softens, is juicy, and has a fragrant aroma. The flavor is sweet and sour and palatable, containing 15%-17% soluble solids and 0.37% acid, of superior quality. The fruit does not store well and can be kept at room temperature for about 20

Characteristics and Key Cultivation Techniques of the Han Xing No. 1 Strain
Han Xing No. 1 was introduced from South Korea by the author. Cultivation trials over several years have shown that this strain has a club-shaped stipe of fairly uniform thickness (see photo), and firm, crisp, tender fruiting bodies with an excellent taste. It is an outstanding variety among king oyster mushrooms. The main characteristics and key cultivation techniques of this strain are described below: 1 Biological characteristics 1.1 Nutrition Han Xing No. 1 requires relatively abundant nitrogen and carbon sources; the richer the nitrogen source, the better the mycelial growth and the higher the yield. It is generally believed that when the carbon-to-nitrogen ratio of the substrate is around 20:1,

What are the methods for selecting Gastrodia elata fungus strains and Gastrodia elata seeds?
1. Armillaria mellea: Some Armillaria mellea varieties are high-yielding and high-quality, while some varieties instead harm and feed on Gastrodia elata, so farmers must be cautious when introducing strains. Our company promotes the Armillaria mellea a-9 variety, selected by the Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences, from numerous varieties at home and abroad. Large-scale application and promotion have shown that this variety has strong vitality, dense branching, a high colonization rate, high yield, and high quality, making it the preferred superior variety for cultivating Gastrodia elata. 2. Germination fungus: The germination of Gastrodia elata seeds must rely on the infection of the embryo by fungal hyphae of a Mycena species to provide
