摘  要:
采用三因素五水平最优回归设计,研究了氮、磷、钾肥配施对南板蓝产量及靛玉红含量的影响。结果表明,不同的氮、磷、钾肥配施显著影响南板蓝的产量。N、P、K肥对南板蓝的增产效应为N>P>K,氮是主要的限制因子。不同的氮、磷、钾肥配施也显著影响南板蓝的靛玉红含量。施入氮肥明显地增加了南板蓝的靛玉红含量,磷、钾肥的施入在一定程度上降低了靛玉红含量。结合南板蓝的产量及靛玉红含量,确定氮、磷、钾肥适宜的用量组合区间,N为931.96~1035.55 kg/hm2,P2O5为140.80~172.80 kg/hm2,K2O为388.80~432.00kg/hm2。

摘  要:
An optimized regression design with three factors and five levels was applied to study the effect of N,P and K fertilizers application on the yield and indirubin contents of Baphicanthus Cusia Bremek.The results showed that N,P and K fertilizers effect the yield and indirubin contents obviously.The effect of increasing yield was N>P>K and N fertilizer was the main factor.The N fertilization increased the indirubin contents obviously,but the P,K fertilizers decreased the indirubin contents.The optimum combination fertilizers of N,P2O5 and K2O was shown to be 931.96~1035.55 kg/hm2,140.80~172.80 kg/hm2,388.80~432.00 kg/hm2.
