How can the efficacy of fishery drugs be improved? These five methods must be mastered
Improve the binder The binder must be highly sticky, otherwise the drug is easily lost in the water. Standard wheat flour is a good binder material. For swallowing fish, it is best to make pelleted medicated bait or ball-shaped medicated bait for feeding. Add a feeding attractant Fish have a keen sense of smell; even if 1 gram of alanine is dissolved in 1 million liters of water, fish can still detect it. For example, if strongly aromatic Chinese herbal medicines such as star anise and Angelica dahurica are ground into fine powder as a feeding attractant, and mixed into fishery drugs at a ratio of 10%-20%, or added to roasted soybean powder, wheat flour, etc., all have obvious attractant

Why is the golden-headed turtle called a masterpiece among turtles?
The golden-headed turtle, also known as the snake-eating turtle, is a specialty of China and originally lived in mountain streams south of the Yangtze River basin; it is now on the verge of extinction. The golden-headed turtle has a smooth, scale-free head, a short snout that does not protrude beyond the edge of the beak, an upper beak with a distinct notch, large eyes, a round and clearly visible tympanum, and a broad golden-yellow arc-shaped stripe behind the eye, hence the name "golden-headed turtle." The golden-headed turtle is a treasure among turtles; its meat is delicious and tastier than that of the golden coin turtle, rich in protein, vitamins and essential amino acids for the human body, and is a premium tonic. The plastron of the golden-headed turtle can be processed into many kinds of traditional Chinese patent medicines

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.

The amount of farmyard manure should be 2 to 3 times the fruit yield, changing the past practice of 1 kg of fertilizer per 1 kg of fruit, and it should be applied in early autumn after harvest. Control the amount of nitrogen fertilizer, increase the proportion of phosphorus and potassium fertilizers, and maintain the application ratio of nitrogen, phosphorus and potassium fertilizers at 1:0.6:1. While fertilizing, pay attention to watering during early spring and autumn droughts, and tree-disk mulching and whole-orchard mulching can also be used to prevent

How to save garlic seed? Mastering these tips is key
Garlic loses vigor because it is propagated vegetatively by replanting cloves year after year, resulting in weak, stunted plants, poor disease resistance, smaller bulbs and lower yields. In concentrated garlic-producing areas, seed selection, seed saving and purification and rejuvenation should be carried out properly. Selecting bulbs and cloves Before harvest, select plants in the field, mark those that match the variety's characteristics, grow vigorously and are free of pests and diseases, and pick them out as seed at harvest. At harvest, also choose bulbs that are large and round, free of deformed cloves, undamaged, uniform in size, and with skin color, flesh color and clove division matching the variety's characteristics; dry, braid and store them separately; select again when planting, remove rotten, damaged, soft and yellowed cloves caused by heat, freeze injury or bruising, and plant large cloves; bulb and clove selection must be done every year, which can improve the seed stock's quality.

How to harvest garlic? Master these technical key points
1. Harvesting garlic scapes. Garlic scape harvesting is highly time-sensitive; once they have grown, they must be harvested promptly. Timely harvesting of garlic scapes can ease the competition for nutrients between the scapes and the garlic bulbs, makes the scapes tender in texture, and also promotes rapid bulb swelling. From differentiation to harvest, garlic scapes generally need 40-45 days, and from emergence to harvest about 15 days; the best harvest time for garlic scapes is when the spathe turns white. The morphological signs of mature garlic scapes are: when the scape bends into an arch, the portion of the scape axis above the point where it contacts the second-to-last leaf turns light yellow by 4-5 cm

There's an art to winter pond fish harvesting, and mastering the method is key
Winter is a favorable time for harvesting and marketing pond fish, but winter harvesting is also a potential trigger for fish diseases the following year. Therefore, extra care must be taken during winter harvesting to avoid injuring the fish as much as possible, so as to reduce the occurrence of fish diseases and improve the economic returns of the pond. 1. Clear debris from the pond before harvesting. Wooden stakes set up in the pond for theft prevention, uncleared large rocks, and aquatic plants on the water surface such as water hyacinth and alligator weed can all interfere with normal seining. To carry out winter harvesting smoothly and safely, these must be cleared before harvesting
