In the past 10 years, with the increase in the trading price of animal medicines in the herbal medicine market, the market prices for glutinous glutinous rice cake, dried oysters and dried oysters have also been increasing, mainly due to the rapid decline in the survival of wild quail due to changes in the ecological environment. In many parts of the world, people have been eating oyster meat for a long time. The meal in restaurants is hot and expensive. Therefore, wolfberry medicinal products are on the verge of depletion, and it is very difficult for some areas to catch oysters used for authentic Chinese medicinal materials.
Therefore, artificial breeding of earthworms has emerged in some places and the technology has matured. The key to artificial breeding is to keep the winter off. The beak is a variable temperature amphibious reptile that enters hibernation before the onset of winter each year. In the natural world, most crickets climb into the water for winter, such as rivers, lakes, ponds, puddles overwintering, and a few drill into the soil for winter. Most of the people who breed fish live in ponds over winter. This method of overwintering is chemical, large and expensive, and it is not easy to do in water-scarce regions and mountains. Jiang Zhanglin, director of the leading museum of amphibians and reptiles in Haining, Zhejiang Province, after many years of experiments, found that crickets can completely overwinter on dry land. As long as the conditions are met, they can safely survive the winter and can even reach 100% survival. This method is simple and easy. The line is as follows:
In front of the house can be closed to miscellaneous land, wasteland, slopes and other places, the best choice for the sun, the land plowing, the depth of about 20 cm, the northern region deeper. In the land after turning, open several vertical drains vertically and horizontally.
In order to prevent the escape of the cockroaches after they are put into the room and wake up after winter hibernation, the overwintering site should be surrounded by a thick plastic film. A plastic film with a width of 80 cm can be used to enclose the land after it has been turned, depending on the perimeter of the length of the ground. The plastic film is buried under the soil at a depth of about 20 cm, and about 60 cm is left on the ground. Then the upper part of the ground is replaced with a bamboo stick. The plastic film is supported and forms a wall to prevent escape. Because the plastic film is relatively smooth, it will not jump high and cannot climb out. Plastic film joints with a sticky tape, generally available for 3 years -5 years.
In the enclosed land, about 10 stockings are kept per square metre, allowing them to drill into the loose soil and overwinter. In the 2 days to 3 days after entering, the earthworms drilled into the soil one after another, and then some straw, hay or stalks were covered on the top to prevent the sun from drying or drying after the long-term solarization or drought. When dead, it can also prevent heavy soil from causing soil compaction. It is safe to keep the soil slightly moist. Normally it will be no problem if it is dry for a month. If it is too dry, it can be sprinkled with some water. In case of long-term rain, we must prevent water accumulation, so as not to cause suffocation in soil.
