[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(13)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、3 g。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。
[Objective] The research aimed to discuss the best N, P, K application rate of Fuyuan konjac. [Method] A total of 14 treatments of N, P and K were designed by greenhouse pot experiment and “3414” experiment scheme to study the effects of different treatments on the yield of konjac originated from Fuyuan. [Result] The yield of basic fertility treatment (1) was 184.53 g, which was 37.99% of that of treatment (6). The highest yield of treatment (13) was 696.20 g and the growth coefficient was 6.94 Treatment (1) increased yield by 277.28%. Treatment (4) had the lowest yield of 295.00 g and growth coefficient of 2.90, which was 59.87% higher than that of treatment (1). The effects of N, P, K fertilizers on yield of konjac were P, K, N, and the effects of P deficiency on yield were greatest. NP combination, NK combination has a good synergistic effect, can increase the yield of Fuyuan konjac. [Conclusion] The suitable application rates of N, P and K for the single Fuyu flower were 3,1 and 3 g respectively. In the field of production, according to the actual soil conditions and konjac N, P, K needs timely replenishment of nutrients to ensure the good growth of konjac.
