| 摘 要： | 为了探讨马铃薯原种在小垄栽培(垄距70 cm)条件下的适宜种植密度,利用马铃薯品种荷兰15号脱毒原原种为试验材料,种植并生产原种一代。采用单因素随机区组设计,设株距10 cm、15 cm、20 cm、25 cm和30 cm共5个处理,采用通径分析探讨了植株性状对产量的影响,运用方差分析探讨了密度与植株性状(株高、主茎数和茎粗)、产量性状(单株结薯数、平均薯块重、单株产量、产种量、繁殖系数、公顷产量)和经济参数(产投比和经济效益)的关系。研究结果表明:株距在10~30 cm之间时,如果株高越高、主茎数越多,那么产量就越高;随着株距的增大,单株结薯数逐渐增多,单株产量逐渐增高,繁殖系数和产投比逐渐增大,主茎数和产种量无显著变化;垄株距为70×30 cm的处理产量最高,繁殖系数最大,产投比最高和经济效益最好,是小垄稀植栽培的适宜密度。

| Abstract: | Minitubers of the c ultivar Favorita were grown in randomized complete block design with the narrow row of 70 cm wide at 10,15,20,25,and 30 cm apart between hills to study the optimal density for Elite seed potato production.Path analysis was used to study the influence of plant character on yield,while analysis of variance was used to investigate the relationship of plant density with plant character(plant height,main stem number,and stem diameter),yield character(tuber number per hill,mean tuber weight,tu... |
