Soybean contains a high content of plant protein, which is more than 36 grams per 100 grams. Sheep liver contains high content of vitamin A, carrots are rich in nutrition, and the crude fiber contained in them has excellent defecation effect, which is indispensable for nymphs. Mix 2 parts of soybean, 2 parts of carrot, 65,438+0 parts of sheep liver and 65,438+0 small bags of dry yeast and grind them into paste with a meat grinder. When feeding, cut the fresh leaves into blocks, spread the twisted feed on them and can them. You can put a few more pieces in each can, up and down, so that nymphs can eat. Because nymphs eat less, don't wrap the feed too thick to avoid wasting. Keep the food fresh every day. Feed it now, not every other day. Feed it regularly, 1 time a day, preferably twice.
Keep it in the gourd, that is, the kind of long gourd, that is, the vegetable gourd. Wash the gourd gall with a small amount of tea every day to keep it moist!
Since the Qing Dynasty, family members of officials inside and outside the palace loved to hear the crisp sound of Guo, especially in winter. Every snowy season, they will gather in one place, put their own slugs in a warm room, enjoy the snow and enjoy the sweet songs of slugs. This custom has lasted for a hundred years, and now it has become a great pleasure for ordinary people in winter.
Speaking of raising slugs in winter, Mr. Kou Jinbao is the most authentic one. Since 100 years ago, the Kou family has accumulated a lot of experience in raising slugs, which has been passed down from generation to generation until today. Mr. Kou told reporters that the slugs that can be raised in winter are generally farmed artificially. Every year from August to the end of September, Mr. Kou will go to the mountainous area to buy a large number of adult female slugs (also called donkeys, with a long ovipositor at the tail, which has no wings and can't sing) and bring them back to the breeding base. After mating, they lay eggs in the soil. 10, the newly hatched larvae need careful care most. They usually eat carrots coated with soybean flour. Environmental temperature and sunlight will affect the future color and shape of slugs. At the beginning of June 1 1, these larvae basically ended metamorphosis and entered the adult stage. Simply put, adult slugs can be divided into four varieties according to their colors and shapes: the cyan ones are called "mountain green", which looks as bright and clear as wax products when they are still; Black (or dark brown) is called "iron filings"; The color similar to hay is called "grass white"; Another kind of pure green is called "green slug". These adult slugs are basically carnivores, and breeders can feed them some "bread worms" every day or occasionally some vegetables and fruits to achieve the goal of balanced nutrition.
In winter, the most important thing is to master the environmental temperature for feeding slugs. Under normal circumstances, when the temperature is higher than 27-28 degrees Celsius, the fruit will start to sing loudly, but it is forbidden to bake the gourd used to raise the fruit on the heating. Singing for a long time will also shorten the life of the fruit. When the ambient temperature is below 20 degrees Celsius, about 16 degrees Celsius, the slug will stop singing. Of course, the temperature should not be too low, and slugs are easy to die below 0 degrees Celsius. Generally speaking, these winter slugs can live to May Day of the following year. But there are also many excellent breeders who can make them live to the next August, which lies in carefully matching their diet and controlling the temperature of their living environment.
In addition, feeding winter slugs is not only fun in itself, but also the gourd used to hold slugs is very particular. The appearance of those gourds has quite complicated patterns. These patterns are not carved, but formed during the growth of the gourd through the mold. In the Qing Dynasty, there were "official models", "civilian models" and "local models". The structure of the gourd is also very clever. Usually, a coiled copper ring is placed at the mouth of the gourd, and a porous cover is added. In this way, the sound made by grasshoppers singing in the gourd belly will be more crisp and elegant.
Nowadays, more and more people raise fruit in winter, which seems to be a great pleasure for ordinary people to live and relax. It is true that the fruits of Mr. Kou's breeding base were snapped up half a month ago. Of course, there is still a lot of experience in feeding slugs, which needs to be explored in practice. It is understood that this kind of winter slug is sold in all major markets of flowers, birds, insects and fish in Beijing.
