摘要
为探明甘薯品种龙紫9号在烟地的高效栽培条件,利用正交试验L9(34)研究套种时间、栽插方式和肥料对龙紫9号鲜薯产量、大薯率、淀粉和可溶性糖含量的影响.结果表明,各因素对龙紫9号鲜薯产量的影响依次是栽期(A)＞肥料(C)＞栽期与肥料互作(A×C)＞栽插方式(B),组合A2B1C2在6月1日栽种、两烟株之间垄两边对角栽插两株薯苗、施用腐殖酸肥15kg/hm2配合复合肥225kg/hm2的处理鲜薯产量最高.各处理对龙紫9号大薯率的影响因素主要是栽期,组合A1B1C1在5月20日栽种、两烟株之间垄两边对角栽插两株薯苗、施用复合肥450 kg/hm2的处理大薯率最高.各处理对龙紫9号淀粉含量的影响依次是肥料(C)＞栽期(A)＞栽期与肥料互作(A×C)＞栽插方式(B),组合A1B3C3在5月20日栽种、两烟株之间垂直于垄栽插两株薯苗、施用海藻酸肥16 L/hm2配合复合肥225 kg/hm2的处理淀粉含量最高.各处理对龙紫9号可溶性糖含量的影响不明显.
Abstract
In order to explore the highly efficient cultivation conditions of Longzi 9 on tobacco field,the yield of fresh storage roots,large tuber rate,starch and soluble sugar contents were studied by the orthogonal test.The orthogonal test L9(34)was demonstrated that the best combination of fresh storage root yield was found by planting on June 1st,placing two sweet potato plants on opposite sides between two tobacco plants,applying humic acid fertilizer(15 kg/ha)and compound fertilizer 225 kg/ha,and the interaction between interplanting time(A)＞fertilizer(C)＞planting time and fertilizer(AxC)＞planting methods(B),the best combination of yield of fresh storage roots was A2B1C2,obtained by planting on June 1th,planting two sweet potato plants on opposite sides between two tobacco plants,applying humic acid fertilizer 15 kg/ha and compound fertilizer 225 kg/ha.The main factors affecting the percentage of large storage roots of Longzi 9 was planting time.The highest large storage root rate was combination A1B1C1,when it was planted on May 20th,two sweet potato plants were planted on opposite sides between two tobacco plants,and 450 kg/ha compound fertilizer was applied.The effects on starch content were as follows:fertilizer(C)＞interplanting time(A)＞interaction between planting time and fertilizer(A×C)＞planting methods(B).The highest starch content was combination A1B3C3,obtained by planting on May 20th,two sweet potato plants planted perpendicular to the ridge surface,fertilizer 16 L/ha and compound fertilizer 225 kg/ha was applied.The effects of different treatments on the soluble sugar contents of Longzi 9 were not obvious.
