| 摘 要： | 为了筛选出适宜青海旱地推广种植的青贮玉米(Zea mays)品种,引种了3个品种在海拔2 040m的青海旱地进行比较试验。结果表明,豫玉22号综合性状表现突出,株高314.80cm,单株鲜重1 148.67g,单株干重257.96g,单株绿叶数13.60片,鲜草产量121 066.95kg·hm-2,较金穗3号和金凯3号分别增产44.70%和6.74%,干草产量分别增产11.42%和11.09%。干草中粗蛋白含量达6.94%,粗脂肪含量达13.87g·kg-1,钙含量达3.82g·kg-1。以上结果说明,豫玉22号可在青海旱地推广种植。

| Abstract: | In order to select the suitable silage Zea mays varieties for popularisation in the dry land of Qinghai,we introduced three varieties and conducted comparative experiments at an altitude of 2 040 m in the dry land of Qinghai.The results showed that the comprehensive characters of Yuyu 22 were outstanding,with a plant height of 314.80 cm,single plant fresh weight of 1 148.67 g,single plant dry weight of 257.96 g,green leaf number of 13.60,and fresh yield of 121 066.95 kg · ha-1.The fresh yield increased by 44.70％ than that of Jinsui 3,and by 6.74％ than that of Jinkai 3,and the hay yield increased by 11.42％ and 11.09％ than that of Jinsui 3 and Jinkai 3,respectively.The crude protein content of hay was 6.94％,the crude fat content was 13.87 g · kg-1,and the calcium content was 3.82 g · kg-1.Yuyu 22 can promote cultivation at the dry land of Qinghai. |
