粮饲兼用玉米(Zea mays)是指既可在成熟期收获籽粒,还可用秸秆作青饲料或青贮饲料的玉米[1]。试验采用了3个优质玉米杂交品种,以当地推广品种新玉9号为对照,进行丰产性和适应性的对比试验。试验结果表明,新玉29号综合性状表现良好,产量最高,为14 342 kg/hm2,较对照品种增产19.05%,居第一位;新玉13号、新玉35号产量分别为14 138.02 kg/hm2和12 959.13 kg/hm2,居第二、三位,均高于对照品种新玉9号。
Zea mays is corn that can be harvested both at maturity and straw as a green or silage. Three high quality maize hybrids were used in the experiment, and the local popularization variety Xinyu 9 was used as a control to carry out comparative experiments of high yield and adaptability. The results showed that the comprehensive performance of Xinyu 29 was good, with the highest yield of 14 342 kg / hm2, up 19.05% over the control. The yield of Xinyu 13 and Xinyu 35 was 14 138.02 kg / hm2 and 12 959.13 kg / hm2, ranking second and third, both higher than the control variety Xinyu 9.
