摘要
为探寻锌肥在高寒草地对垂穗披碱草产量及品质的影响。试验试剂为ZnSO_4·7H_2O,Zn含量21%,试验牧草为垂穗披碱草(Elymus nutans Griseb),喷施浓度分别为500、600、700、800、900、1000和0 mg/kg(CK) 7个梯度锌溶液,通过对比物候期、生长速度、饲草产量、营养成分、种子产量和越冬率来筛选出适宜喷施锌溶液浓度。结果表明,在喷施800 mg/kg锌溶液浓度时,能较好的促进高寒地区垂穗披碱草的产量及品质。
In order to explore the effect of Zn fertilizer on the yield and quality of Elymus nutans Griseb in alpine meadow, the effects of dif- ferent Zn fertilizer concentration( (500, 600, 700, 800, 900, 1000 and 0 mg/kg ) on Elymus nutans Griseb in alpinee meadow were stud led. The results showed that 800 mg/kg Zn fertilizer can better promote the yield and quality of Elymus nutans Griseb in the alpine region.
