| 摘 要： | 试验在施肥水平、管理方式、播种密度一致的条件下,对7个饲用玉米Zea mays品种产草量等生产性能进行了比较,结果表明:鄂玉10号产量最高,其干物质产量21 060.75 kg/hm2;青饲02号产量最低,其干物质产量仅15 448.95 kg/hm2;从总体上来看,各个品种之间产量差异显著(P<0.05)。不同青贮饲用玉米品种经济效益不同,鄂玉10号的经济效益最高,比经济效益最低的青饲02号高145.8%。

| Abstract: | Plot test was used to compare production performances of 7 silage corn varieties under the same fertilization level,management,and seeding rate.The result indicated that Eyu No.10 was the best with 21 060.75 kg/hm2 dry matter yield.Qingsi No.2 was the lowest with only 15 448.95 kg/hm2 dry matter yield.Significant differences were observed among the varieties (P<0.05).Different variety had different economic profit;Eyu No.10 was the highest,145.8% higher than that of Qingsi No.2. |
