Xianke Giant Crucian Carp: Introduction to a Newly Bred Crucian Carp Variety
The Xianke Giant Crucian Carp is an omnivorous fish variety that feeds mainly on plant-based feed. Its survival water temperature is 0-38°C, feeding water temperature is 10-35°C, growth water temperature is 15-32°C, suitable growth environment pH is 5-8.5, and salinity is 0-7‰. The Xianke Giant Crucian Carp has strong adaptability to feed. At the juvenile stage, it mainly feeds on plankton. When its body length reaches more than 6 cm, it begins to shift to plant-based feed as the main food while also eating organic debris and commercial feed. The Xianke Giant Crucian Carp grows quickly, and after half a year to 1 year of farming it generally can grow to 0.6-1.5 kg

Introduction to the Ganoderma New Strain Satellite No. 2 Variety
"Satellite No. 2 Ganoderma" was sent into space aboard China's recoverable satellite launched as "961020" for a 15-day journey, where it was exposed to large doses of ultraviolet radiation and weightlessness in the cosmos, thereby producing genetic mutations; after screening and cultivation trials, a new high-quality, high-yield Ganoderma strain was selected. Compared with a Ganoderma strain that was not carried into space (the control strain), "Satellite No. 2" can increase fruiting body yield by 75.3%, its high-quality product rate reaches 88.9%, its average fermentation rate is 2.57%, and its cellulase activity

How to prevent and control green mold in edible mushrooms? A detailed introduction to practical methods
Green mold disease is a major enemy in edible mushroom cultivation. It is prone to occur in large amounts when raw materials are not fresh, raw material handling is improper, sterilization is incomplete, inoculation is not strict, and the spawning environment is not clean, especially combined with acidic, high-temperature, and high-humidity conditions. Its spores spread quickly through the air and reproduce rapidly. If prevention is inadequate or control is not timely, serious consequences will result. 1. Select fresh raw materials and auxiliary materials that have not been rained on and are not moldy. Raw material handling and fermentation sites must be clean and hygienic. 2. During cooked-material cultivation, sterilization standards must be met and sterilization must be thorough; during fermented cultivation
