摘　　要：为探索福建本地木薯主栽品种的适宜栽培方法,采用L_(9)(3^(4))正交设计,开展了木薯品种(A)、扦插方式(B)和追肥方式(C)三因素三水平的栽培技术试验。结果表明:平放、斜插、竖插的出苗率不存在显著差异,株高、茎径、株型等生长趋势一致;不同扦插方式和施肥方式对株高、茎径影响不大,但同一品种不同生长时期差异大,且品种是影响木薯地上部性状的主要因素;不同扦插方式对块根分布影响较大,平放、斜插块根水平分布,竖插块根垂直分布,其薯径表现差异小,而薯长表现差异大;各处理产量表现差异较大,为40.40~50.70t/hm^(2)。综合生产实际,‘GR911’‘NZ199’产量表现较好,‘SC205’产量表现较差,优先选择组合‘GR911’平放种植、追肥条施及‘NZ199’斜插种植、追肥穴施,其次为‘GR911’斜插种植、追肥撒施。In order to explore the suitable cultivation methods of local major cassava varieties in Fujian,this study used L_(9)(3^(4))orthogonal design to carry out three-level cultivation experiment with three factors:cassava varieties(A),cutting methods(B)and topdressing methods(C).The results showed that there was no significant difference in germination rate among horizontal,inclined and vertical planting,and the growth trends of plant height,stem diameter and plant type were consistent.The plant height and stem diameter have been little effected by different cutting and fertilization methods,but the same variety had significant difference in different growth periods,and the variety was the main factor affecting the shoot characters of cassava.The root tuber distribution have been significant influenced by significant different cutting methods.The root tubers were horizontal distribution with horizontal and inclined planting,and vertical distribution with vertical planting.The different cutting methods also had little difference in tuber diameter,but significant difference in tuber length.The yield of each treatment varied widely from 40.40 to 50.70 t/hm^(2).With'GR911'and'NZ199'showing better yield and'SC205'showing poor yield performance in the actual production situation,the optimal planting methods were'GR911'+horizontal planting+row fertilization and NZ199'+inclined planting+hole fertilization,while'GR911'+inclined planting+broadcast fertilization was in the second place.
