桑品种“育2号”具有发芽早、发芽率高、生长芽多、生长快、发条力强等优点,利用它补植桑园缺株比“湖桑32号”生长势有显著差异。近两年试验,在“湖桑32号”幼年桑园里分别补植“育2号”和“湖桑32号”大苗,培管措施均相同,当年和第二年“育2号”株平条长分别为10.3尺、20尺,株别产叶分别为0.67斤、1.45斤;“湖桑32号”株平条长分别为6.4尺、11.8尺,株别产叶分别为0.42斤、0.83斤.两年合计,“育2号”比“湖桑把号”增产桑叶近七成·在成年桑园里均利用健壮桑株补植,“育2号”第二年株平条长31尺,株平产叶2.12斤Z“湖桑32号”株平条长15.8尺,株别产叶1.05斤,产叶量相差一倍F“育2号”明显地提高了桑田的经济效益。同时,“育2号”对桑树黄化型萎缩病有较强的抗病力,在同块
The mulberry cultivar “Yu-2” has the advantages of early germination, high germination rate, more sprouting buds, faster growth and stronger clockwork. Nearly two years of experiment, in the “mulberry 32” young mulberry were planted “Yu 2” and “Husang 32” seedlings, training measures are the same, the year and the second year “Yu 2” strain The lengths of flat strips were 10.3 and 20 feet, respectively, with 0.67 kg and 1.45 kg leaves respectively. The lengths of “Husang 32” flat were 6.4 and 11.8 respectively, 0.83 kg .Two years together, “Yu 2” than the “Lake Mulberry No.” mulberry leaf yield increased by nearly 70% in the adult mulberry are using robust Mulberry replanting, “Yu 2” the second year of flattening Long 31 feet, yield 2.12 kg Zhu-ping Z “Husang 32” strain flat 15.8-foot long, strains do not produce 1.05 kg leaves, leaf yield doubled F “Yuk 2” significantly increased the economy of Kuwata benefit. At the same time, “Yu 2” has a strong disease resistance to mulberry yellow type atrophy, in the same block
