Secondary bagging of edible fungi can effectively prevent infection
In the production of shiitake mushrooms (Lentinula edodes), lion's mane mushrooms (Hericium erinaceus), wood ear mushrooms (Auricularia heimuer) and others, the secondary bagging technique is applied (that is, when the mushroom logs come out of the sterilization chamber, an extra layer of thin film bag is put on, so that the mushroom logs inside the bag do not come into direct contact with the ambient air), which effectively solves the problem of cross-infection during the log production process and keeps the strain survival rate above 97%. The technique is described below: 1. Preparation of the outer bag The outer bag should preferably be a low-density polyethylene film bag with a circumference 2 cm larger than the inner bag, a length 5 cm longer than the inner bag, and a thickness of 0.2 silk, with one end tied and sealed for later use.

How effective is Huoxiang Zhengqi Shui (Agastache Rugosa Qi-Correcting Liquid) in treating a cow's cold?
A draft cow suffered from uninterrupted diarrhea and dysentery due to exposure to wind-cold in winter. The next day it was fed an appropriate amount of charcoal powder, which took effect at the time, but it soon relapsed. On the third day its hair stood on end and its body trembled, and it still had uninterrupted diarrhea; it was diagnosed with a gastrointestinal-type wind-cold cold. Based on an estimated cow weight of 250 kg, it was given 5 vials of Huoxiang Zhengqi Shui, mixed into warm feed water for drinking. Within a few minutes the cow's bowel movements returned to normal, and its muzzle was no longer dry. Also, because the cow had previously been harmed by doufu jiangshui (drinking too much water), and this substance is cold and cooling in nature, Fuzi Lizhong Wan was therefore given at 5 times the human dosage, used for 2 consecutive days, to

How can cold-water fish farming effectively prevent and control pathogens?
1. Establish a strict quarantine system. When introducing and exporting fish eggs and fry, all farming areas must strictly carry out quarantine to prevent and control the occurrence of diseases. Farms should set up quarantine ponds to isolate introduced fish species; only after the introduced fish are confirmed free of important diseases may they be temporarily reared. Quarantine ponds are generally located at the end of the drainage ditch. The length of quarantine time should be determined by the transport season, water temperature, and the characteristics of the disease. When the average temperature is not lower than 12°C, 20 days are required; when the water temperature is higher, it can be shortened, which is determined on the basis that the lower the temperature, the longer the incubation period. If

What to do about a high egg breakage rate? Sharing effective reduction methods
Broken eggs account for about 6-8% of total egg production, bringing considerable losses to laying hen production. Below are methods to reduce egg breakage. 1. Meet nutritional needs, especially calcium and vitamin D3 levels, while keeping phosphorus at an appropriate level and managing the calcium-to-phosphorus ratio well, generally around 3.4-4.6:1. 2.

What are the effective methods for protecting pepper seedlings from freezing in winter?
During winter pepper seedling raising, sudden cold waves often strike, the temperature drops abruptly, and the seedlings are prone to freezing damage. If the temperature drops slowly, they are less likely to freeze. If the temperature is not very low but lasts for a long time, especially when low temperature is accompanied by rain, a condition known as "wet cold", the seedlings are also very prone to freezing damage. The severity of freezing damage to the seedlings is also related to how quickly the temperature rises after the low temperature. If the temperature rises slowly, the seedlings thaw slowly and easily regain their vitality. If the warming and thawing are too
