What are the preservation techniques for shiitake mushrooms? Introduction to commonly used methods
Shiitake mushrooms have a relatively high respiration rate, and in environments with high temperatures and dryness they lose water very easily, causing the fruiting bodies to shrivel; if the ambient humidity is high, they are prone to rot. The preservation and handling methods for fresh shiitake mushrooms are introduced as follows: 1. Low-temperature preservation. When the fruiting bodies are 60% mature, stop watering for 1 day, and harvest on the next morning or before noon. When harvesting, pinch the very bottom of the base of the fruiting body and twist gently to remove it; avoid pulling the stipe so that it breaks or the cap separates from the stipe, or so that substrate is pulled off with it. After harvesting, spread the fresh mushrooms in a single layer in the workroom, light a stove

Many Methods for Propagating Goji Berry: A Full Analysis of Commonly Used Propagation Techniques
1. Seed propagation: Spring sowing should be carried out from late March to mid-May, when temperatures rise noticeably. Soak the seeds in 30°C warm water for 24 hours, then rub them, pick out the flesh and skin, take out the sunken seeds, and dry them. Mix the seeds with wet sand at 1:3, then place them indoors at about 20°C to germinate, keeping them moist. When about 30% of the seeds have cracked and shown white, germination is complete. For the nursery site, loam or sandy loam near a water source can be chosen as the seedbed. It requires flat terrain, good drainage, and ample sunlight. Apply 5000 kg of decomposed barnyard manure per mu

Several commonly used green and environmentally friendly fishery drugs in aquaculture
Quicklime, table salt, and the like are not dedicated fishery drugs, but they are highly effective for preventing and treating aquatic diseases, pose no threat to the environment, and leave no drug residue problems. Quicklime: Regularly splashing quicklime into aquaculture water bodies can not only reduce the occurrence of many diseases, but also provide the calcium element essential for cultured organisms, which is especially important for crustacean aquaculture. Method of use: Choose quicklime that has not weathered; for pond clearing and disinfection, use 150-200 kg per mu; for disease prevention and treatment, generally 5-9, use once about every 20 days

What are the commonly used drugs for fish? A detailed introduction
At present, there are many kinds of drugs commonly used in fish farming on the market. Because fish drug production is not yet standardized, some products from various manufacturers do not indicate their active ingredients, and the trade names of some similar finished drugs are not consistent with their corresponding chemical names. This is not conducive to our understanding of the active ingredients of drugs and also creates certain difficulties for scientific and rational medication. In order to popularize fish disease prevention and treatment technology, we will successively introduce knowledge about drugs commonly used in fish farming. This is expected to improve our understanding and awareness of commonly used drugs so that drugs can be used scientifically and rationally in production.
