Snail farming technology

First, the site selection 1, field cultivation: fertile soil should be selected, loose field cultivation, green vegetation, planting vegetables, while the choice of rattan high pole protection class for three-dimensional cultivation, to create a snail suitable for the "Eco House", temperature Restock above 18°C. 2, indoor breeding: Indoors are conducive to insulation, moisturizing the room. The size of the space depends on the size of the building. There are ventilation facilities. The walls are best covered with plastic foam boards to facilitate insulation. Moisturizing facilities can be used wooden boxes, foam boxes, stratified aquaculture with cement boards, height do not exceed 30 cm, the specific method should be based on the scale of farming. Breeding soil, choose fertile garden soil or fermented soil, both moisturizing and not caking. Second, the choice of snail species 1, white jade snails individual large, fast growth, but in the winter to maintain a suitable temperature of 20 °C or more. 2. Light snails and snails are hardy and do not need to warm in winter. Natural winter in the room, but summer temperatures are high to sleep. White jade snail snail specifications to 30-50 grams, bright snail 15-30 g / only, bulk snail 8-18 g / only appropriate. According to the local climate, first-time adopters should adapt their measures to local conditions and should not be introduced blindly. Only after understanding the specification requirements of each species can the scale of breeding be considered. Third, the preparation of feed Snails are omnivorous animals, commonly used feed: green feed, also known as basic materials, it contains a large number of chlorophyll, and a variety of proteins, minerals and vitamins. Fresh, easy to digest, including a variety of vegetables, some leaves, niche plants, etc., snails most like to eat lettuce leaves, dandelion, as well as a variety of melon and bean leaves, juicy feed pumpkin, East melon, watermelon rind , gourd, sweet potato, cucumber and so on. Mink feeds include cereal seeds and their processed by-products. It is rich in starch, phosphorus, sulfur and vitamin E, aromatic in taste and good in palatability. Such as wheat, rice bran, corn flour, beans, millet and so on. Animal feed has a high protein content, rich in calcium, phosphorus and vitamin B, and essential amino acids such as fish meal, bone meal, silkworm cocoon powder, alfalfa meal, eggshell powder, shell powder, and shrimp shell powder. Feed mix: 80-90% of green material, 10-20% of concentrated feed, specific ratio adjusted at any time according to different periods of snail growth, can not be used for a long time with the same formula, otherwise there will be stiff screw, reduce production. Fourth, feeding and management of feed modulation and feeding 1, preparation of a good feed, concentrate feed and protein feed must be crushed, melon and fruit and tuber slices or drawing, the advantage of doing so is that the material incense, easy to digest, the water will turn over Paste into a paste, adhere to feed on the green feed, feeding time to time, usually from 5-6 in the afternoon is better, once a day or two days once, the number of feeding should be mastered in the next feeding basically finished It is appropriate. 2, the temperature control: The appropriate temperature is the prerequisite for the normal growth of snails, room temperature at 16-33 °C, the best is 26-30 °C, the temperature dropped to 15 °C should be insulation, so there will be no hibernation and It grows well. However, attention should be paid to the fact that there is less air in the greenhouse at the time of insulation, and the temperature must not exceed 30°C within 20-25°C. In the hot summer days, ventilation is required, and the number of water sprays in the room is increased to meet the requirement of lowering the temperature. Bright snails and snails are best to spend the summer in shelters. 3. Control of humidity: The level of humidity directly affects the growth and reproduction of snails. When the surface soil temperature and air humidity are moderate, activities are normal and growth is rapid. When encountering a dry environment, the snail is inactive. If the environment is too dry for a long time, it is easy for snails to die. How to solve such conflicts? The soil must contain organic garden soil and fermented soil. This kind of soil can easily maintain the original water content. In the winter heat preservation, attention should be paid to the sealing of the box so that the water in the soil in the box does not escape. When each feeding is performed, the amount of water sprayed should be determined according to the actual situation, so that the water can be damp without water accumulation. 4. Management of species snails: Strong snails should pay attention to the ratio of green fodder to concentrate fodder, increase the content of high protein content, such as fish meal, silkworm cocoon 20%, bone meal, lime, concentrates, the total proportion of 20%, but Look at the food situation and adjust the proportions. The snail environment is clean and the soil is loose. The feed soil should be changed in time. The smelly soil will affect the breeding and hatching rate. The species is weak in postpartum constitution, and it is necessary to pay attention to feeding antibiotics during spawning, which is usually twice a week, with a ratio of 0.7% to 1%, which promotes postpartum recovery and mainly prevention. The hatching method adopts natural hatching. Putting the eggs in the hatchery box is basically the same as the original ecology. A layer of wet fine soil is covered on the top of the hatching box. Take care not to break the egg pieces to prevent premature drying or destruction of the mucous layer of the egg surface and maintain a certain temperature. , Humidity, after a week the snail naturally hatches, maintains the humidity with a spray, the amount of water depends on the humidity. 5. Management of young snails: young snails are fed three days after hatching, and a small amount of young leaves or tender flowers are placed. Feeding time should not be too early. Feed it once every two days. After eating as a standard, the humidity of the young snail is relatively higher than that of the snail and the growing screw. When the heat is kept, the flue can be placed near the flue. Water spray. The juvenile snails do not have to feed the concentrate within 2 weeks. Afterwards, they can add concentrate but should be fine, add lime, yeast powder 5%, and timely adjust their formula according to the growth conditions. V. Transport methods The species screw must not be sprinkled with water before it is transported, and feed and water can not be fed on the way. After long-distance transportation, the snail itself loses more water, but it does not rely on water spray to solve the problem. It should be fed with fruits and fruits. Succulent feed, put potted water in the box to allow it to naturally feed to supplement the water, create a suitable environment before the introduction, the snail will not have "love nest" phenomenon, can reduce unnecessary losses.

Theory of the hifu for wrinkle removal system

High Intensity Focused Ultrasound (HIFU) directly delivers heat energy to skin and subcutaneous tissue that can stimulate and renew the skin's collagen and thus consequently improving the texture and reducing sagging of the skin. It literally achieves the results of a facelift or a body lifts without any invasive surgery or injections, moreover, an added bonus of this procedure is that there is no downtime. and also, it works equally well for people of all skin colours, in contrast to that of lasers and the intense pulse lights.


Application range

1. Suitable for people over 30, the skin just started to enter the aging, a single therapy can help accelerate the active cells, the treatment effect is more significant and long-lasting.
