How to prevent and treat bluetongue in cattle and sheep in summer? All the methods are here
Bluetongue is a viral infectious disease, and its main transmission vectors are Aedes mosquitoes and Culex mosquitoes. Cattle and sheep are susceptible to infection after being bitten. Clinical symptoms: in the early stage, the sick sheep's body temperature rises to 42°C, with listlessness, reduced appetite, lagging behind the flock, runny nose and drooling, edema of the upper lip, and the swelling can spread to the entire face and ears, with congestion and cyanosis of the oral mucosa. After fever, the epithelium of the oral mucosa, especially the lips, cheeks, and tongue, becomes eroded and ulcers develop. Blood seeps from the ulcer surface, and secondary infection causes necrosis of the mucosal epithelium, oral fetor,

How to control cotton aphids in summer? These methods you need to master
Control of cotton aphids in summer. 1. Rotate the use of pesticides. Rotate the use of conventional field pesticides such as acetamiprid, imidacloprid and chlorpyrifos to reduce the likelihood of aphids developing resistance. Once aphids develop resistance to a certain chemical pesticide, even if you increase the number of applications and raise the pesticide concentration, you will not achieve the desired control effect. 2. Spray the affected parts evenly and thoroughly. Cotton is now in full bloom and the plants are tall, so when spraying you must be careful and thorough, focusing on spraying the undersides of the leaves in the middle and lower parts of the cotton plant, strictly preventing missed spraying and missed coverage, and truly

Cultivation of oyster mushrooms (Pleurotus pulmonarius) during the summer idle period can utilize shiitake mushroom sheds in high-altitude mountainous areas
Pleurotus pulmonarius is a medium-temperature variety, with a fruiting range of 15-28°C and an optimum of 18-22°C, and can fruit naturally in spring and autumn. Because Pleurotus pulmonarius has the characteristic of fruiting under variable temperature, under environmental conditions above the fruiting temperature range, proper low-temperature differential stimulation (temperature difference above 10°C) can promote fruiting body formation. In current production, during the summer high-temperature season when temperatures exceed 28°C, the method of placing physiologically mature spawn bags in a 2-4°C cold storage for cold stimulation for 10-12h, then moving them to the mushroom house for fruiting, is adopted for off-season

Pollution-free Cultivation Techniques for Pleurotus pulmonarius at High Altitudes in Summer
Pleurotus pulmonarius, also known as yellow-white oyster mushroom, lung-shaped oyster mushroom, pocket mushroom, Ji pinggu, small pinggu, etc., taxonomically belongs to the phylum Fungi, subphylum Basidiomycotina, class Hymenomycetes, order Agaricales, family Pleurotaceae, genus Pleurotus, and is named for its elegant appearance and delicious taste. Pleurotus pulmonarius is rich in protein, sugars, vitamins, and trace elements such as iron and calcium; in particular, its protein content is higher than that of button mushrooms, shiitake mushrooms, straw mushrooms, and other edible fungi, hence it is also called the "finest of mushrooms." Pleurotus pulmonarius can be stir-fried, cooked in soup, or used for hot pot, and is deeply favored by consumers; its market sales and

How to care for bonsai in summer? Five taboos of summer care and management
1. Avoid fertilizing. In the high heat of midsummer, leaves lose water relatively quickly. Fertilizing at this time will make the solute concentration of the trunk's cells lower than that of the external environment, causing water in the plant cells to flow backward into the soil, and the trunk will die from dehydration caused by fertilizer damage. 2. Avoid drought. Watering when you remember and not watering when you forget, sometimes leaving it unattended for several days in a row, and only quickly replenishing water once the leaves are found to be wilting, after which the leaves return to normal - this is a response of the trunk to adapt to the environment, but if this continues over the long term, excessively strong transpiration will ultimately make the trunk difficult to recover from serious illness and cause it to die of dehydration.

Xingguang Fuqiu Eggplant is an eggplant variety suitable for cultivation in summer and autumn
Xingguang Fuqiu Eggplant was developed by the Jiangsu Nanjing Xingguang Vegetable Research Institute. It is a mid-early maturing variety with long, thick club-shaped fruit and ink-black skin, generally about 30 cm long and about 8 cm thick, with a single fruit weight reaching up to more than 500 g. It has good market quality, strong disease resistance and adaptability, and is especially tolerant of heat, moisture, aging, and storage and transport. Because its benefits are extremely notable during the off-season for summer and autumn vegetable supply, it was named Xingguang Fuqiu Eggplant. Sow at the proper time and stagger the harvest for market. In the Yangtze River basin region, Xingguang Fuqiu Eggplant can be sown from mid-to-late September of the previous year to July of the current year

Raising Pigs in Summer: Never Pour Cold Water on Pigs
In summer, when the temperature is high, pigs often pant heavily from the heat. Some farmers, worried that the pigs will fall ill from the heat, pour cold water over them, hoping to cool them down and make them more comfortable, not realizing that this does more harm than good. Pigs pant from the heat because they do not sweat efficiently, so the heat in their bodies cannot be released for the time being. If cold water is poured on a pig at this point, the intense cold stimulation causes the sweat pores all over the pig's body to contract sharply, blocking the release of body heat, and the body temperature instead rises abruptly. In mild cases this causes high fever and lung inflammation; in severe cases it can lead to the pig's death. Therefore, in the height of summer, never

How to Prevent Heatstroke and Cool Down Pigs in Summer? A Detailed Guide to Practical Methods
Pigs are afraid of heat. In the hot summer, if heatstroke prevention and cooling methods are improper, pigs will suffer heatstroke and in severe cases die, causing unnecessary losses. The heatstroke prevention and cooling methods are as follows: 1. Suitable temperature: Because pigs vary in body weight, their growth and development requirements for suitable temperature differ. For a pig weighing about 20 kg, the suitable ambient temperature is 24°C; for 50 kg, 23°C; for 100 kg, 20°C. In general, the temperature suitable for pig growth is 15-28°C, and the optimal temperature is 22°C. If the temperature reaches 35°C and cooling work cannot keep up, pigs weighing 45 kg

Feeding and Management Methods for Keeping Caged Rabbits Safe Through the Summer
Heat dissipation and temperature control: Plant some vine-type plants such as melons, beans, grapes, and pumpkins around the rabbit hutch to prevent direct sunlight, and you can also apply a layer of lime slurry to the inner and outer walls of the rabbit hutch so that direct sunlight does not reach the rabbit cages; open-air rabbit hutches should have a shade canopy set up, with doors and windows opened to allow air convection; for wool rabbits, the wool should be cut short along with the hair on the head and face, and the rabbit cages should not be too crowded; when the room temperature exceeds 30°C, sprinkle some cool water every 2-3 hours, or use a new brick, soak it in cool water for several minutes, and once it has absorbed enough water (no longer bubbling), place it in the rabbit cage,

Special attention must be paid to preventing coccidiosis when raising rabbits in summer
Rabbit coccidiosis is one of the most common and most harmful diseases of domestic rabbits. Rabbit coccidia are single-celled protozoa that parasitize the liver, bile duct epithelial cells, and intestinal epithelial cells of rabbits. When coccidia parasitize the body, the rabbit becomes emaciated, anemic, has rough fur, and its development stalls, ultimately leading to death. This disease has no obvious seasonality and can infect and cause illness throughout the year, but it occurs more frequently in the hot and humid seasons of summer and autumn, and its distribution and prevalence are extremely widespread. To prevent coccidiosis: 1. Maintain the sanitation of the rabbit hutch, frequently disinfect the cages and
