The key points for the development of Huang Huan are "Choose a good seed", "Water should be adjusted well", "Plant planting is good", "Bait feeding is just", and "Prevention of disease is good." Prepare the seedlings of Astragalus: The main source of Astragalus seedlings is the artificial propagation of Astragalus seedlings, but the number is currently relatively small. The key is the cultivation of aphids and the selective maturation of the inbreds. Then the injectable oxytocicants are artificially inseminated to hatch the same fish. Incubation method; semi-artificial method, without artificial insemination, letting the natural spawning after injecting oxytocin and then incubating with the family fish; collecting natural seedlings, and in the May-September period in rice fields, ditches, lakes, shallows weeds or In order to obtain foam accumulation, Chengyu aquaculture ponds were hatched and hatched and then incubated in water at 25°C-30°C. Cultivate seedlings: The seedlings should be cultivated in a small cement pool, with a depth of 30px-1000px. The bottom of the pool should be filled with about 125px of soil. It can be disinfected with “Qinboqiang Chloride†or quicklime clear pond; 0.5kg/m 2 -1kg/ Square meters of organic fertilizer or application of "amino acid fertilizer water paste", "fermented spider treasure" and other culture water quality; transplant silkworms, water hyacinth or water peanuts and other aquatic plants; open mouth bait best silkworm can also be fed to zooplankton Such as "Red worm" or fish, egg yolk, etc., or use "soybean milk feeding method"; cultivation density 1000 / square meter - 2000 / square meters, later to reduce the density, pay attention to the timely separation of the size, so as not to kill each other. One species preference: The artificially cultivated alfalfa species can be optimized during the cultivation process, but most of them are currently purchased in the wild, so it is necessary to pay attention to the optimization. Injuries to the body surface, electrical trapping (with congestion), hook catching, abnormal posture and body color, and significantly less mucus can not be purchased. Common species include: dark yellow large brindle pupa, dark yellow body color, irregularly distributed brown large spots throughout the body, this kind of fast growth, strong adaptability, large individuals, is the best species of culture; , body color red, full of spotted, good adaptability, fast growth, large individuals, is a high-quality breeding object; pale yellowish brown spot, body color is light yellow, smaller and smaller spots, no spotted lines, rapid growth , Adaptability is better, because the source is widely cultivated species; other, such as body color blue, light black, light white and other slow growth rate, especially the blue tincture is almost no growth, and poor adaptability. Domestication: In the artificial cultivation of earthworms, we must consider the cost and the source of the feed. Therefore, we must eat it in time, start feeding for 3 days, and then feed the earthworms, yellow mealworms, snail meat and fly maggots, and gradually mix them with other ingredients. feed. After 7 days, the fixed proportion feed can be stably added. The tame time begins in the evening or at night. If necessary, it can be fed during the day and then slowly lead the time to the daytime. However, the yellow pheasant raises Chengdu to feed in the evening so as to facilitate the food intake in the evening. Before disinfestation, it should be disinfected: Use 3%-5% saline or "bacterial net", "Povidone iodine solution" to bath for 10 minutes. And pay attention to temperature difference <2 °C to prevent colds.
Press Lock Wire Seals are combined by a piece of wire and a plastic locking body. The locking body has some anchors to provide locking mechanism. So they are also called anchor seals. The anchor seal body is always made with polycarbonate material.
The anchor seals are originally designed as a replacement for lead seals. The application of the anchor seals include: Hospital Equipment, EMS Equipment, ATM Cassettes, Zipper Bags, Coin Boxes, Storage Units, Fibre Drums etc.
