High yield and quality of propolis

Propolis is currently the best-selling bee product. The current status of propolis production is: First, the output is low, and the second is poor quality, which restricts the development and application of propolis. According to the experiment, Caucasian bees prefer to take propolis. In order to increase the production of peak glue, hybrids of high bee and Italian bee can be promoted, and the advantage of hybridization can be used to increase the production of propolis. The promotion of nylon gauze is the next step. The specific approach is to use nylon yarn to replace the iron yarn on the cover. After the nylon yarn is covered with propolis, it is replaced with a new nylon yarn. Propolis nylon yarn will be placed in the freezer and frozen. At present, it has been ascertained that the heavy metal contamination of propolis comes mainly from iron yarns, and it is simple and easy to use nylon yarn to cover the rubber.
