Content of Nutritional Elements in Sudangrass and Ryegrass Determined by ICP-AES

Abstract：The sudangrass (Sorghum sudanense) and ryegrass (Lolium multiflorum L.) rotation is a new type of cropping system,which has developed rapidly in recent years in the south of China.The contents of nutritional elements for forage grass in the sudangrass and ryegrass rotation system were determined by ICPAES.The results showed that there were abundant and essential nutritional elements for animals in sudangrass and ryegrass.The contents of P,K,Ca,Mg,S,Fe,B,Cu,Zn and Mn for sudangrass were 0.20％ ～0.29％,1.94％～2.57％,0.62％ ～0.97％,0.39％ ～0.69％,0.12％ ～0.18％,108.35～ 180.12,3.04～5.96,6.17～10.02,20.37～31.36 and 46.80～101.29 mg · kg-1,respectively.The contents of P,K,Ca,Mg,S,Fe,B,Cu,Zn,Mn for ryegrass were 0.39％～0.70％,3.77％～5.07％,0.61％～0.84％,0.28％～0.47％,0.32％～0.41％,291.65 ～ 632.20,2.13～3.23,13.29～15.19,30.73 ～ 42.98 and 92.08～156.04 mg · kg-1,respectively,and there were differences between various periods in nutritional elements in the two forage grasses.The application of ICP-AES could reflect fast and efficiently the content of nutritional elements for forage grass as animals feed. 作者： Author： LI Wen-xi[1]  LU Jian-wei[2]  Saman P Seneweera[3]  WU Ji[4]  CHEN Fang[5]  LU Jun-ming[1]  LI Xiao-kun 作者單位： College of Resources and Environment, Huazhong Agricultural University, Wuhan 430070, ChinaSchool of Agriculture and Food Systems, Faculty of Land and Food, the University of Melbourne, Horsham, Victoria 3401, AustraliaCollege of Resources and Environment, Huazhong Agricultural University, Wuhan 430070, China Institution of Soil and Fertilizer, Anhui Academy of Agricultural Sciences, Hefei 230031, ChinaInternational Plant Nutrition Institute, China Program, Wuhan 430074, ChinaAgricultural and Technical Center, Datonghu Administration District of Honghu City, Honghu 434300, China 期 刊： 光譜學(xué)與光譜分析   ISTICEISCIPKU Journal： Spectroscopy and Spectral Analysis 年，卷(期)： 2011, 31(9) 分類號(hào)： O657.3 Keywords： ICP-AES    Sudangrass    Ryegrass    Nutritional elements    機(jī)標(biāo)分類號(hào)： S31 S15 機(jī)標(biāo)關(guān)鍵詞： ICP-AES    elements    cropping system    differences    application    grass    essential    type of    results    fast    two    new 基金項(xiàng)目： International Plant Nutrition Institute，the National Key Technologies R&D Program of China，National Department Public Benefit Research Foundation
