摘要
为满足淮河流域日益增长的优质牧草需求与丰富淮河流域农业生产模式,通过田间试验,采用熵权法对箭筈豌豆、毛苕子、金花菜在淮河流域的草产量、品质与土壤养分进行分析。结果表明,箭筈豌豆的草产量较高,兰箭333A干草产量最高,为1041.59g/m^(2);淮扬金花菜在参试品种(系)中品质最好,粗蛋白含量达27.81%,相对饲用价值为176.24;箭筈豌豆、毛苕子、金花菜对土壤碱解氮、速效磷、速效钾、有机质含量均有提升作用,金花菜提升作用最为显著,土壤碱解氮、速效磷、速效钾、有机质含量平均增加了56.25%、51.96%、25.60%、57.20%;熵权分析结果表明,兰箭333A与淮扬金花菜的加权关联度分别达0.8107、0.7974,综合评价结果最好。
In order to meet the growing demand of high quality forage and enrich the mode of the agricultural production in Huai river basin,field experiments were conducted to analyze the forage yield,quality and soil nutrients of common vetch,hairy vetch and burr medic in the Huai river basin by using entropy weight method.The results revealed that the forage yield of common vetch was higher,and Lanjian 333 A common vetch had the highest hay yield,1041.59 g/m^(2).Among the tested varieties(lines),Huaiyang burr medic had the best forage quality with crude protein content of 27.81%and related forage value(RFV)of 176.24.Common vetch,hairy vetch and burr medic could increased the content of alkali-hydrolyzed nitrogen,available phosphorus,available potassium and organic matter in soil,while Burr medic had the most effect significant effect,increasing the contents of soil alkali hydrolysable nitrogen,available phosphorus,available potassium and organic matter by 56.25%,51.96%,25.60%and 57.20%,respectively.The results of entropy weight analysis showed that the weighted correlation degress of Lanjian 333 A common vetch and Huaiyang burr medic was 0.8107 and 0.7974 respectively,and the comprehensive evaluation result was the best.
