摘要
针对阜阳地区玉米新老品种良莠不齐 ,良种良法不配套的现状 ,研究筛选出适合该地区种植的玉米良种及农大 10 8的配套栽培技术。结果表明 :适合该地区种植的良种有 :农大 10 8、9988、豫玉 2 2等 ;农大 10 8的配套栽培技术是 :6月中旬播种 ,密度为65 685株 /hm2 ,每公顷施氮量 3 15kg ,分 2次施 ,苗期施 60 %,喇叭口期施 40 %。最高产量潜力为 93 5 8.45kg/hm2 。
The adaptability of several new varieties and their cultural practices, such as Nongda 108, in Yingzhou of Fuyang city were studied. Results showed that varieties suitable for planting in this area were: Nongda 108, 9988, Yuyu 22, Zhongdan 321, Yedan 19and Wan 46×Huangzao 4 etc. The appropriate planting model of 'Nongda 108' was: sowing date in mid-June, planting density of 65,685 plants/hm 2, Nitrogen fertilizer of 315kg/ hm 2 applied for twice(60% in seedling stage and 40% in trumpet mouth). And the highest potential of yield was 9, 358.45kg /hm 2.
