摘　　要：为筛选适于机械化收获的优质桑品种,2020年杭州市从浙江省农科院引进了“试1号”“试2号”“试3号”“试4号”4个杂交桑新品种在淳安进行比较试验。经2年试验调查,4个杂交桑新品种平均年产片叶产量,“试1号”为47589 kg/hm^(2),“试2号”48981 kg/hm^(2),“试3号”53197 kg/hm^(2),“试4号”49561 kg/hm^(2),分别比对照品种“农桑14号”高38.49%、42.54%、54.8%、44.22%。养蚕比较试验结果,4个新品种平均万蚕茧层量,分别为4027.34 g、4068.76 g、3964.66 g、3951.08 g,略优于对照。杂交桑机械收获效率是“农桑14号”人工采摘的16.3倍。推广杂交桑品种省力高效,对稳定杭州蚕桑产业意义重大,但其叶片较薄,容易失水、尚需育出更加优良的杂交桑品种。In order to select high quality mulberry varieties suitable for mechanized harvest,in 2020,4 new hybrid mulberry varieties(Trial No.1,Trial No.2,Trial No.3 and Trial No.4)introduced from Zhejiang Academy of Agricultural Sciences were tested in Chun'an County.Through two years'experiment and investigation,the average annual leaf yield of 4 new hybrid mulberry varieties was 47,589 kg/hm^(2)(Trial No.1),48,981 kg/hm^(2)(Trial No.2),53,197 kg/hm^(2)(Trial No.3)and 49,561 kg/hm^(2)(Trial No.4),respectively 38.49%,42.54%,54.8%and 44.22%higher than that of the control(Nong mulberry No.14).The results showed that the average cocoon shell weight of 10000 silkworms fed 4 new hybrid mulberry varieties was 4027.34 g,4068.76 g,3964.66 g and 3951.08 g respectively,which was slightly better than that of the control.The mechanical harvesting efficiency of hybrid mulberry was 16.3 times higher than that of artificial harvesting of Nong mulberry No.14.It is very important to popularize hybrid mulberry varieties for stabilizing sericulture industry in Hangzhou,but its leaves are thin and easy to lose water,so it is necessary to breed better hybrid mulberry varieties.
