摘 要:针对榆林市饲料木本植物种质资源匮乏问题,在榆林市榆阳区进行了优良木本饲料品种试验,结果为引种的6个饲料桑品种和1个构树品种的越冬保存率埋土均高于不埋土;所有饲料桑品种越冬保存率栽植第二年高于第一年,构树相反;所有参试品种产量一年平茬一次高于一年平茬两次;构树最抗病,饲料桑选七九二抗病性最差;树叶粗蛋白含量丰驰2号最高(18.9%),构树最低(11.4%)。选七九二、丰驰1号、丰驰2号等3个饲料桑品种适于在榆林市推广栽植,建议栽植第一年冬前埋土,一年只收获平茬一次。In light of shortage of fodder resources in Yulin,experiment with woody fodder crops were conducted by introducing 7 species into Yulin.The result showed that 6 varieties from mulberry and 1 from paper mulberry can go through winter with higher survival rate when covered with soil.The yield of mulberry varieties are higher than that in first year when going through winter,which is just contrary for paper mulberry.All the varieties by stumping once have higher yield than by stumping twice.Variety from paper mulberry has highest tolerance and variety 792 from mulberry has lowest tolerance.Variety Fengchi No.2 has highest crude protein in leaves(18.9%)whereas paper mulberry has the lowest(11.4%).Varieties 792,Fengchi No.1 and Fengchi No.2 are highly recommended for growing in Yulin.
