Guangxi is the largest raw cocoon base and silk processing base in China and even in the world.As a characteristic and advantageous industry,sericulture industry has played a major role in promoting farmers’ income and laid a solid foundation for rural revitalization.The efficient promotion of new silkworm varieties fits the way of high-quality development,it can realize the renewal of silkworm varieties,improve production efficiency and benefit.However,with the development of the market economy and changes in policies,the traditional government led promotion model gradually highlights issues such as insufficient grassroots technical personnel,reduced government investment,and low efficiency in one-way promotion.Therefore,it is of great significance to explore and study the extension model of Guangxi new silkworm varieties under the new situation.Through literature research,expert interviews,field research and analytical comparison methods.Firstly summarize the main body,path,and effectiveness of the traditional promotion model of new silkworm varieties led by the government,and analyze its advantages and existing problems.Further research on the promotion model of new silkworm varieties "Guican No.8" led by enterprises.By comparing it with the traditional promotion model of new silkworm varieties,it is concluded that the promotion model of Guican No.8has the following four characteristics.First is the growers have a income of 5million yuan through achievements transformation;the second is enterprise has the exclusive breeding rights;the third is has more promotion subjects,paths,and funding sources;the fourth is the bidirectional promotion transmission mechanism.The promotion mode of Guican No.8 has the advantages of improving promotion efficiency,helping to maintain seed quality,increasing silkworm farmers’ satisfaction,and shortening promotion time.The promotion model of Guican No.8 has problems such as insufficient funds,lack of professional talents,poor risk resistance,and challenges such as large fluctuations in cocoon prices,chaotic supervision of the silkworm seed market,low profits and comparative benefits.Aiming at the problems and challenges,it proposes to raise funds through multiple channels to improve the hardware strength of the enterprise;attach importance to enterprise talent cultivation and popularize professional and technical training;integrate resources to create a brand and reduce risks through group development;take multiple measures to stabilize cocoon prices and identify the confidence of farmers;strengthen the supervision of all parties to achieve excellent cocoon quality and price;implement digital management to improve production efficiency and efficiency;improve the protection mechanism and protect the intellectual property rights of achievements. |
