How to prevent and control frost damage to young and newly planted tea trees? These seven methods must be mastered
1. Apply winter manure. Young and newly planted tea trees have relatively weak cold resistance, so before overwintering, a heavy application of winter manure should be combined with earthing up and mounding around the base. The fertilizer should mainly be farmyard manure, stable manure and biogas residue, which have a certain heat-preserving effect, along with a certain amount of cake fertilizer, superphosphate and potassium sulfate fertilizer. Winter manure can not only preserve heat and prevent freezing and enhance the tea trees' freeze resistance, but also lay a good foundation for the tea trees' growth the following year. 2. Earth up and mound around the base. Preventing the root crown from freezing is a key measure for protecting young and newly planted tea trees from frost. Therefore, before young and newly planted tea trees overwinter, they should

How to treat swine asthma? Sharing effective remedies and new methods
Swine asthma is a chronic disease characterized mainly by coughing and wheezing, accelerated breathing, audible wheezing sounds, a dog-sitting posture, foamy discharge from the mouth and nose, and reduced appetite, and it mostly occurs in cold, damp weather or when the climate changes abruptly. Affected by feeding management and sanitary conditions, the mortality rate is relatively high when secondary infection occurs. The following combination of drugs can cure it in a very short time, with good results. The method is: inject 1 ml of Houttuynia cordata injection and 10 ml of ciprofloxacin hydrochloride injection per kilogram of pig body weight, and inject 5-10 ml of methylene blue injection and 0.01-0.03 ml of atropine sulfate injection per pig, all by intramuscular injection, twice a day, with 4 days as one course of treatment, and two courses for severely ill pigs.

How to prevent and treat Newcastle disease in chickens? These methods you need to master
Newcastle disease in chickens, also called Asian fowl pest, commonly known as fowl plague, is a highly contagious, acute, and virulent infectious disease of chickens caused by Newcastle disease virus. It often presents as septicemia, with the main features being difficulty breathing, diarrhea, nervous system disorders, and hemorrhage of mucous membranes and serous membranes. I. Epidemiological characteristics: chickens of all breeds and ages can be infected, with young chickens and growing chickens being more susceptible, and older chickens over two years of age having reduced susceptibility. The main sources of infection for this disease are sick chickens and virus-carrying chickens; their secretions, feces, as well as contaminated feed, drinking water, non-susceptible wild birds, external parasites, humans and livestock can all transmit the pathogen. The main routes of transmission are the digestive tract and respiratory tract, and it can also invade the body through damaged skin and mucous membranes. It can occur in all four seasons. In non-immune areas or in flocks with low immunity, once a velogenic strain invades, it can spread rapidly, causing a devastating epidemic, with morbidity and mortality reaching over 90%. At present, in large and medium-sized @#@230@#@ farms, where flocks have a certain level of immunity, Newcastle disease mainly appears in an atypical form, which should be given attention.

How Should Garlic Be Stored? Five New Methods to Teach You
There are many methods for storing garlic. Depending on the storage purpose and conditions, methods such as hanging storage, heap storage, burial storage, radiation storage, and chemical treatment storage can be used. They are specifically introduced as follows. 1. Hanging storage method: When harvesting garlic, the garlic intended for hanging storage should be strictly selected, removing those heads that are too small, have rotten stems and leaves, are damaged, or have been affected by moisture. Then spread them on the ground to dry in the sun until the stems and leaves become soft and yellow, and the outer skin of the garlic is dry. Finally, select 50 to 100 garlic heads of uniform size, braid them, and hang them under a cool, ventilated, rain-sheltered eave so they are air-dried and stored.

New Rapid Propagation Technology for Hybrid Gastrodia: Detailed Explanation of Two Methods
I. Potted Breeding Method for Gastrodia Arrow Bud Mother Corms (Using Yidu Red Gastrodia as an Example) 1. Potted Seedling Cultivation: Around Qingming Festival, when room temperature stabilizes above 15°C, select fresh, robust, plump-budded, undamaged high-mountain wild red gastrodia arrow bud mother corms weighing 100-150 g (labeled Wild Red) and plains-cultivated red gastrodia arrow bud mother corms (labeled Domestic Red). Plant them separately in river sand in plastic washbasins or enamel basins, evenly placing 4 arrow bud mother corms (plants) per basin, with arrow buds (parrot-beak tips) facing upward and 3-5 cm from the basin edge, covering with 5-

Detailed Explanation of New Lily Propagation Techniques and Methods
Lilies not only have dignified, vivid flowers, but their fleshy tender stems are also rich in nutrients and have special medicinal and health-care effects, making them a best-selling health food on the market. Several bulb propagation methods for lilies are as follows: 1. Seed propagation. Sowing mature lily seeds can quickly produce large numbers of lily bulblets for bulb production and cut flower cultivation. Lily species suitable for seed propagation include: Lilium brownii, Lilium longiflorum, diploid Lilium lancifolium, Lilium concolor, Lilium regale, Lilium formosanum, Lilium davidii, Lilium dauricum, Lilium tsingtauense, Lilium henryi, Lilium speciosum

Several New Methods for Reducing the Contamination Rate of Edible Mushroom Spawn
1. Bottled fermented substrate (1cm). The improved method is: above the culture medium, about 4cm from the bottle mouth, fill in 1-2cm of fermented substrate, then sterilize. Because the fermented substrate itself is sterile, after inoculating the spawn, the mycelium quickly covers the upper part of the whole bottle, and the mycelium feeds on the substrate at the same time. The advantage of this method is that contaminant microorganisms can hardly infect the culture medium, and the spawn age is uniform. The contamination rate can be reduced to below 3%. 2. Wheat grain germination method. The improved method is: let the wheat grains germinate before bottling and sterilizing. The storage substances of wheat grains are mainly starch, fat and protein,

How to Keep Edible Mushrooms Fresh? These 4 New Methods Are Worth Trying
Edible mushroom fruiting bodies are prone to browning and rotting and are difficult to store, which affects their commercial value. Here is a brief introduction to several new methods for keeping edible mushrooms fresh. 1. A new chemical preservation method for oyster mushrooms: Remove impurities from fresh oyster mushrooms and spread them flat on a clean plastic film. Prepare a chemical compound preservative solution of a certain concentration (calcium propionate at 0.3% concentration, potassium sorbate at 0.1% concentration, sodium sulfite at 0.25% concentration), use a sprayer to evenly spray both sides of the oyster mushrooms, then place them in fully sealed plastic bags and store them in a clean and hygienic place.
