| 摘 要： | 为了解氮磷钾配施对金盏花产量的影响,采用"3414"回归设计,对不同氮磷钾配施与鲜花产量关系进行研究。结果表明:氮、磷、钾肥配施能够显著提高金盏花的鲜花产量,各施肥处理的鲜花产量分别比不施肥处理增产4 312.02~12 471.92 kg/hm2。最优产量为48 382.98kg/hm2,其施肥量为:N 169.68 kg/hm2,P2O5111.16 kg/hm2,K2O 67.13 kg/hm2,1 hm2多增加纯收入5 282.04元。

| Abstract: | Study on the effects of different N,P,K combined application on yield of marigold,utilizing 3414 regression design,research the relationship between different N,P,K combined application and yield of fresh flowers.The results showed that N,P,K combined application would significantly increased the fresh flowers yield of marigold,the yield of each fertilizing treatment was increased 4 312.02 kg/hm2 to 12 471.92 kg/hm2 respectively.The optimal yield was 48 382.98 kg/hm2,which fertilizer rate was nitrogen ferti... |
