摘　　要：为确定适宜在石林县推广种植的粮饲兼用型高产优质玉米品种,本试验选取13个玉米品种进行种植试验。玉米完熟期时测定亩产量和营养成分,并分析亩产量与部分农艺性状的相关性。结果:(1)玉米籽粒DM、CP、NEL的亩产量分别为520.08~858.94kg、54.10~76.28kg和1092.07~1793.74Mcal,秸秆DM、CP和NEL的亩产量分别为591.29~859.64kg、28.76~55.86kg和738.09~1166.44Mcal;(2)玉米籽粒CP、EE和Ash含量分别为8.28%~10.60%、3.41%~5.69%和1.03%~1.51%,其中Ca、P含量分别为0.03%~0.04%和0.20%~0.29%,NDF、ADF和ADL含量分别为6.93%~10.65%、2.73%~5.25%和0.29%~0.86%;秸秆CP、EE和Ash含量分别为4.86%~6.95%、0.79%~2.84%和6.09%~8.07%,其中Ca、P含量分别为0.46%~0.91%和0.06%~0.09%,NDF、ADF和ADL含量分别为66.67%~75.47%、39.43%~45.97%和3.30%~6.30%,方差分析显示不同品种间营养成分存在显著性差异(P<0.05);(3)亩产量与部分农艺性状间存在显著的正相关或负相关关系。结果表明,产量最高的为路单17号,但综合指标均优良的品种为TR123。In order to determine maize varieties with high yield and good quality that are suitable for cultivation in Shilin county and can be used as both food and feed, totally 13 corn varieties were selected for planting experiment. Area yield and nutrient composition were determined, followed by analysis of correlation between area yields and some agronomic characters. Results showed that： Q）area yield of DM, CP, NEL in corn grain were 520.08-858.94kg, 54.10-76.28kg and 1092.07-1793.74 Mcal, respectively; area yield of DM, CP and NEj in straw were 591.29-859.64kg, 28.76-55.86kg and 738.09-1166.44 Mcal, respectively. ②Contents of corn grain CP, EE and Ash were 8.28%-10.60%, 3.41%-5.69% and 1.03%-5.69%, with Ca, P content being 0.03%-0.04% and 0.20%-0.29%, respectively; contents of NDF, ADF and ADL were 6.93%-10.65%, 2.73%-5.25% and 0.29%-0.86%, respectively; contents of straw CP, EE and Ash were 4.86%-6.95%, 0.79%-2.84% and 6.09%-8.07%, with the Ca and P being O.46%-0.91% and 0.06%-0.09%; contents of NDF, ADF and ADL were 66.67%-75.47%, 39.43%-45.97% and 3.30%-6.30%, respectively. ③Area yield was significantly positively or negatively correlated with some agronomic characters. Variance analysis showed that different varieties nutrient existed significant difference （P〈 0.05）. These results show that the best single output comes fi＇om LuDan 17, but the variety of excellent comprehensive indexes belongs to TR 123.
