Commonly known as cockroach, it is a kind of economic animal with extremely medicinal value. The white slurry of the glandular parturition of the post-early ear is called "sugar crisp" and is an important Chinese medicinal material. It can treat heart failure, stomatitis, pharyngitis, sore throat, and skin cancer. At present, the prices of glutinous rice cakes in the drug market have reached more than 2,000 yuan per kilogram and have continued to rise. There are three reasons for this: First, chemical pollution has reduced the number of wild apes; second, the survival rate of wild aphids has been extremely low; third, the range of application of the aphids has been increasing, and the demand of domestic and foreign manufacturers for amaranth has been increasing. Therefore, artificial breeding and breeding of eels are a good way to become rich. The methods of artificial feeding of lychee are introduced as follows: 1. The establishment of farms is to be amphibians, so farms should be built near ponds, ditches, and weeds and water sources. There are fences around the farm to prevent run-in and livestock and poultry entry. Second, the collection of seed pods and egg masses can first catch wild large, robust, disease-free, non-injury crickets to make crickets. The ratio of male to female is 3:1; eggs and eggs can also be collected in ponds and rivers, and the eggs can be placed in the water with a water temperature of 10 - 30 degrees Celsius. After 3 - 4 days, the eggs can be hatched. Third, the feeding and management of cockroaches Newly hatched cockroaches live within the egg membrane within 2 days of residual nutrients. After 3 days, feeding was started. The rice bran, wheat bran, kitchen waste, cockroach, fly maggot, etc. can be placed in the artificial rearing. The water temperature is maintained at 16--28 degrees Celsius, the water quality should be fresh, and the water depth should be 0.2--0.4 meters.
