通过随机区组设计试验研究了不同叶龄水果玉米移栽对其缓苗期、成活率、生育期、农艺性状及产量性状的影响。结果表明:水果玉米移栽叶龄越小,成活率越大,缓苗期越短;不同叶龄移栽后水果玉米生育期均延长,并且移栽叶龄越大,生育期越长,收获期越提前;不同叶龄移栽的水果玉米,株高、茎粗、地上节根层和穗位高度均大于直播,而叶片数、穗苞叶数差别不大;不同叶龄移栽的水果玉米,穗重、穗粗、穗长、穗粒重和产量均大于直播,而穗行数差别不大。新疆(南疆)阿拉尔垦区水果玉米育苗移栽以幼苗二叶一心期至三叶一心期较为适宜。
Randomized block design experiments were conducted to study the effects of transplanting corn with different leaf age on its seedling stage, survival rate, growth period, agronomic traits and yield traits. The results showed that the smaller the leaf transplanting age was, the larger the survival rate was and the shorter the rearing period was. The maize growth stages were longer after transplanting, and the longer the transplanting leaf age, the longer the growing period, The earlier the period, the higher the transplanting rate was, the higher the plant height, the stem diameter, the root stratum and the height of spikelet were, but the number of leaves and the number of ear bracts were not different. Fruits transplanted with different leaf ages Maize, panicle weight, panicle diameter, panicle length, panicle weight and yield were all larger than those of direct seeding, but the difference of panicle number was not significant. Xinjiang (southern Xinjiang) Alar reclamation area corn seedling transplanting seedling leaves from one heart to three leaves one heart phase more appropriate.
