摘要
[目的]探讨富源花魔芋的最佳N、P、K施用量.[方法]采用大棚盆栽和"3414"试验方案共设计14个N、P、K施用量处理,研究不同处理对富源花魔芋产量的影响.[结果]基础肥力处理①的产量(收获时单株大芋重量)为184.53 g,是处理⑥的37.99%;处理?的产量最高为696.20 g,生长系数为6.94,比处理①增产277.28%;处理④的产量最低为295.00 g,生长系数为2.90,比处理①增产59.87%.N、P、K肥料对魔芋产量的影响大小依次为P、K、N,缺P对产量影响最大.NP联合、NK联合施用有较好的协同作用,能增加富源花魔芋的产量.[结论]单株富源花魔芋的N、P、K适宜施用量分别为3、1、3g.在大田生产中,可根据土壤实际状况和花魔芋N、P、K需要量及时补充养分,保证花魔芋良好生长.
Abstract
[Objective]To search the optimum fertilization of nitrogen, phosphorus and potassium for Amorphophallus konjac Fuyuan.[Method] 14 different fertilizer treatments were conducted.The effects of different treatments on the yield were researched by using potted plants and"3414" program.[Result]The yield (the largest taro weight at the time of harvest) of basal fertility treatment ① was 184.53 g, and the relative yield was only 37.99%compared with the treatment ⑥.The yield of treatment ? was the highest up to 696.20 g, and the growth coefficient was 6.94, which was 277.28% higher than that of treatment ①.The yield of treatment ④ was the lowest down to 295.00 g.and the growth coeffi-cient was 2.90, which was 59.87% higher than that of treatment ①.The effect of N, P and K fertilizers on the yield of A.konjac Fuyuan was P>K>N, and the effect of lack of phosphorus on the yield was the most obvious.There was a good interactive effect when nitrogen and phos-phorus as well as nitrogen and potassium were be collaborative applied, which could increase the yield of A.konjac Fuyuan.[Conclusion]The optimum application amount of nitrogen, phosphorus and potassium were 3 , 1 , 3 g per plant.In the field production, the nutrients will be add-ed opportunely to ensure A.konjac Fuyuan according to the actual situation of soil and the requirements of A.konjac Fuyuan on nitrogen,phos-phorus and potassium.
