摘要
本研究应用逼近理想解的排序方法(DTOPSIS法)从累计干物质产量、累计粗蛋白产量和累计可消化干物质产量对13个一年生牧草禾豆混播组合进行综合评价,筛选出适宜川西平原种植的HC3(25%多花黑麦草+75%金花菜)、HJ2(50%多花黑麦草+50%箭筈豌豆)、HC2(50%多花黑麦草+50%金花菜)3个优势混播组合,比多花黑麦草单播干物质产量提高12.28%~14.43%、粗蛋白产量提高34%~45.67%、可消化干物质产量提高10.41%~18.76%。
Dynamic technique for order preference by similarity to ideal solution(DTOPSIS)method was applied to evaluate thirteen mixture combinations of annual grass-legume by cumulative dry matter yield,cumulative crude protein yield and cumulative digestible dry matter yield.The dominant mixtures included HC3(25%annual ryegrass+75%mutagenesis of burclover),HJ2(50%annual ryegrass+50%common vetch),HC2(50%annual ryegrass+50%mutagenesis of burclover)in the Western Sichuan Plain.Compared with single sowing with annual ryegrass,the dry material production,crude protein production and digestible dry material production increased by 12.28%to 14.43%,34%to 45.67%and 10.41%to 18.76%,respectively.
