摘要
利用扫描电镜及能量分散型荧光 X射线新技术分析小麦族 10种多年生禾草叶片的可消化性和矿物质含量。结果表明 ,供试草种叶片可消化性的高低顺次是 :老芒麦 >野大麦 >航道冰草 =加拿大披碱草 >蒙农杂种冰草>诺丹冰草 >肥披碱草≥新麦草 =披碱草 >蒙古冰草。叶片中 7种矿物元素含量变幅为 :Mg 0 .2 1%～ 0 .5 7%、Si0 .90 %～ 3.31%、P 0 .2 7%～ 0 .36 %、S 0 .36 %～ 0 .6 0 %、Cl 0 .2 1%～ 0 .5 2 %、K 1.4 4 %～ 3.0 6 %、Ca 0 .4 2 %～0 .98% 。
The leaf digestibility and mineral content of 10 grasses of Triticeae were analyzed by using scanning microscope and energy dispersive X ray technique.The order of leaf digestibility of the grasses was Elymus sibiricus>Hordeum brevisubulatum>Agropyron cristatum cv.'Fairway'= E.Canadensis>A.cristatum×A.desertorum cv.'Hycrest Mongnon'> A.desertorum cv.'Nordan'> E.excelsus≥Psathyrostachys juncea=E.dahuricus>A.mongolicum. The mineral element content range in the leaves of the tested grasses was Mg 0.21%～0.57%,Si 0.90%～3.31%,P 0.27%～0.36%,S 0.36%～0.60%,Cl 0.21%～ 0.52% ,K 1.44%～3.06%,Ca 0.42%～0.98%,and the differences among the grasses were significant.
