| 摘 要： | 从分布于吉林省西部科尔沁沙地的蒙桑资源中 ,选择出具有叶大、质优的桑树品种向海桑 1号 ,进行人工繁殖并与其它桑树栽培品种作对比试验。向海桑 1号不仅具有较强的抗干寒特性 (年降水量 30 0mm ,极端温度 -4 0℃ ) ,而且产叶量高 ,单株产量达 6 30 86g ,迟硬化率 86 2 % ,养蚕成绩与其它桑树栽培品种相似。测定表明 ,向海桑 1号的叶片中粗蛋白含量 16 87%、粗脂肪含量 4 34%、灰份含量 8 78%、干物质含量 38% ,除粗蛋白含量外 ,其它营养成分均相当于或高于对照桑品种秋雨。该品种适于在北方干旱、寒冷地区栽植。

| Abstract: | Morus mongolia Schneid is one of mulberry species with most high cold and drought tolerance.In this research,a species called Xianghaisang No.1 with big leaf and good quality was selected during the species surveying,and the comparative trials among Xianghaisang No.1 and other mulberry varieties have been carried out.The results showed that there had significant differences among the Xianghaisang No.1 and other mulberry varieties in cold tolerance ,whereas there were no significant differences among the Xianghaisang No.1 and other mulberry varieties in foliage yield and performance of raising silkworm.Xianghaisang No.1 has 630.86 g foliage yield per plant,86.2% hardening delayed rate,16.87% rough protein content,8.78% ash value and 38% dry matter.Every characters are similar compared with CK variety except the content of rough protein.Xianghaisang No.1 can be extended in the cold-drying area of the north China. |
