What production management measures should be taken for edible fungi after a rain disaster?
(1) Harvest promptly to reduce losses. Although it is now the late stage of the black fungus arrangement phase, there is still some yield and income. Wait until the weather clears, then harvest all the black fungus, remove the moldy and rotten ones, rinse the good fungus clean with water, and then sun-dry them to reduce losses. (2) Promptly turn and sun-dry the raw and auxiliary materials for edible fungi. If the raw materials and auxiliary materials used for edible fungus production this year have been soaked with water, they must be immediately turned and sun-dried after the flood to prevent the raw materials from becoming moldy. (3) Promptly clear ditches and drain water. If the black fungus arrangement field is flooded or washed by large water, promptly carry out the black fungus cultivation

What should be noted when keeping clownfish in a mixed tank?
Clownfish belong to the damselfish family (Pomacentridae), and they all have rather aggressive temperaments, especially showing hostility toward newly introduced fish of the same kind. Mixed keeping is not a problem, but the following conditions are required: 1. Several fish should be introduced into the tank at the same time, with the time interval kept as short as possible, and the smaller individuals introduced before the larger ones. 2. There should be a large number of sea anemones (carpets) in the tank; for three kinds of fish, at least three sea anemones (carpets) are needed. 3. The tank must be large enough, and the sea anemones (carpets) should be distributed evenly. The above three points only help avoid fights among them as much as possible, but they cannot

What are the precautions for stocking fish fingerlings in early spring? Farmers should keep these points in mind
1. Fingerling quality: The fingerlings to be stocked should be of the same species and same age, uniform in size, robust and uninjured, with intact scales and fin rays, strong upstream swimming ability, and after being removed from water, the gill cover should not open and the fish should keep jumping. 2. Fingerling disinfection: When disinfecting fingerlings, note: ① The medicine should be prepared and used immediately; use clean water to prepare the solution, avoid using fertilized water, and avoid direct sunlight when soaking the fingerlings in the medicine. ② The dosage must be accurate, avoiding insufficient or excessive medication. ③ The soaking time should be appropriate. If signs of poisoning appear in the fingerlings, immediately add water

Targeted measures should be taken for cotton management in the middle and late stages
This year, cotton was affected by unfavorable weather such as low temperatures, cloudy and rainy days, and insufficient sunlight in the early stage, resulting in weak growth and delayed development of plants over large areas. In addition, severe natural disaster weather such as heavy rain and typhoons has occurred frequently recently, making the cotton production situation very serious. Cotton is currently in a critical growth period, and all localities should adopt targeted technical measures, strengthen cotton field management, promote the transformation of seedling conditions, and strive to achieve a bumper cotton harvest. 1. Fertilizer management. Focus on the application of topdressing fertilizer and the mixed spraying of pesticides and fertilizers in the later stage. Generally, apply 5-7.5 kg of urea per mu to increase bolls and boll weight and prevent premature senescence. For cotton fields with late boll setting, few bolls in the middle and lower parts, or sufficient flower and boll fertilizer with late application timing, where cotton plants are still growing vigorously at the Beginning of Autumn, fertilizer should mainly be applied by spraying, with supplementary application in fertilizer-deficient areas. For cotton fields deficient in potassium and boron, promptly spray potassium fertilizer and boron fertilizer in combination with pest and disease control.

What should be noted before koi are introduced into the pond?
Transporting koi is simple: just place them in a plastic bag filled with oxygen. Juvenile or medium-sized fish can be carried by the hobbyist, but large fish are usually shipped by the dealer. New fish carry a high risk of pathogens or parasites, and if not handled properly they often infect healthy fish. Therefore, the transport water should preferably be dosed with salt and antibiotics. Anchor worms and fish lice are visible to the naked eye; if found, they must be removed immediately and the wounds disinfected. The most important thing is adjusting the water temperature. Dealer pond water is generally warmer than the hobbyist's pond water. If the temperature difference exceeds 5°C, the fish easily catch cold,

Several feed types that should not be fed to sows, or should not be fed in large amounts
1. Distillers grains. Although distillers grains are rich in crude protein and crude fat (especially dried distillers grains, whose crude protein content reaches 2%-25%), they lack carotene, vitamin D and calcium, and also contain a certain concentration of alcohol. Therefore, it is not suitable to feed large amounts to pregnant sows and lactating sows, otherwise it easily causes pregnant sows to miscarry and to give birth to stillborn or weak piglets. Even if piglets are born, they are prone to diarrhea. 2. Starch residue. Starch residue is a by-product of making starch or starch noodles from raw materials such as peas, adzuki beans or potatoes. It contains very little crude protein and starch, and is of poor quality.

What should you do if the chicken flock suffers carbon monoxide poisoning?
(1) Cause: Carbon monoxide poisoning is a toxic disease of poultry caused by inhaling carbon monoxide gas, characterized mainly by systemic tissue hypoxia resulting from the formation of a large amount of carboxyhemoglobin in the blood. Poultry houses often have a history of burning coal for warmth; cracks in the heated kang, a blocked or back-drafting chimney, tightly closed doors and windows, and poor ventilation can all prevent carbon monoxide from being discharged in time, causing poisoning. (2) Disease characteristics: Among the poisoned chickens, difficulty breathing and restlessness are commonly seen, soon progressing to standing motionless or paralysis,

How should reishi mushroom bridge worms be prevented and controlled?
The reishi mushroom bridge worm (scientific name to be determined) belongs to the order Lepidoptera, family Geometridae. This pest damages reishi mushroom fruiting bodies. Young larvae feed on the surface and edges of the cap, causing pits and notches. After the 3rd instar, they can bore directly into the interior of the fruiting body and excrete large amounts of frass, which not only contaminates the mushroom bodies but also encourages the proliferation of weeds such as green mold, harming reishi mushroom growth and reducing yield and quality. (1) Morphological characteristics. Adult: body length 12 mm, wingspan 25-28 mm, body grayish black; antennae filiform, outer margin of forewing with 8 small black spots, a larger black spot in the middle of the costal margin,

How should Neurospora disease in lingzhi (reishi) be prevented and controlled?
The scientific name of Neurospora is Neurosporasitophila Sh. et Dodge; it is also called red bread mold (Neurospora sitophila) or red bread mold, bread mold, Neurospora, and Monilia. It belongs to the subdivision Ascomycotina, order Sordariales, genus Neurospora. It is a contaminant fungus that poses a very great threat in the production of lingzhi edible mushroom spawn. It spreads relatively quickly. Symptoms: after the mother spawn is infected, flesh-red to red conidial masses form on the outside of the cotton plug, surrounding the entire bottle mouth, and at the slightest touch there is a phenomenon of powder scattering and spreading.

What are the medication precautions for dogs? Owners should keep these points in mind
There are 4 commonly used methods of administration: oral, injection, enema and topical, and each of them has several ways. (1) Oral administration 1) Mixing with feed. Mix the drug directly into an appropriate amount of feed the dog likes and stir well, letting it eat on its own. If necessary, withhold one meal beforehand. This method is suitable when the sick dog still has an appetite and the drug has no unusual taste, is non-irritating and the dose is not large. 2) Oral dosing. When the dose of tablets, pills or capsules is not large, they can be wrapped directly in soft paper, the sick dog's mouth opened, and the packet placed over the tongue
