摘　　要：湖桑是起源于杭嘉湖地区的桑树群体品种。杭嘉湖地区众多地方品种的形成始于南宋时期。湖桑适于在杭嘉湖平原低湿环境中种植,南宋时期杭嘉湖平原圩田开发过程中湖桑已得到了普遍种植。湖桑苗的育成时间长,技术环节多,南宋时期杭嘉湖地区的人们通过各种技术措施控制桑的树形与枝条的定向生长,并将具有优良变异性状的枝条进行嫁接繁殖。湖桑的形成与杭嘉湖地区长期使用的精细桑树种植技术与桑园管理技术有着密切的联系。Mulberry Husang is a population cuhivar involving several hundred landraces origi- nally planted in the Hangzhou-Jiaxing-Huzhou Plain in northern Zhejiang province as early as the Southern Song Dynasty. The landscape between the Taihu Lake and Qiantang River changed through the past one thousand years. Many swamps were turned into arable lands in the Hangzhou-Jiaxing- Huzhou Plain in the Southern Song Dynasty and mulberry Husang are growing well in the low-lying fields. Farmers might discover some directional variation when they were pruning or cultivating or picking in the mulberry garden They selected the branches which had the excellent variation and used them to graft. They were quite fond of planting the grafting mulberry since the Southern Song Dynasty and they used many technologies to control the height of tree trunk, and created a set of technologies in the process of mulberry pruning.
