摘要
为探明地黄栽培需要的最佳复合肥种类和施用方法,采用L18(6×36)混合正交试验,研究复合肥种类、施肥量、施肥次数对地黄产量和品质的影响,并采用多指标综合加权评分法优选最佳的施肥方式。结果表明,在所选择的6种复合肥中,阿波罗复合肥的施用效果优于其他5种复合肥,全生育期施肥3次效果最好,在所选择的水平范围内,不同施肥量产生的差异无统计学意义。最佳的施肥方式为:施用阿波罗复合肥,全生育期施肥3次,每次施肥量为599.7kg/hm2。
Mixed orthogonal design L18 (6× 36) was used to study the effects of compound fertili- zer types(six levels), fertilizer quantity(three levels) and fertilization times(three levels) on yield and quality of Rehmannia glutinosa. The results showed that the optimum compound fertilizer was Apollo, the optimum fertilization times was three, and the optimum fertilizer quantity of each time was 599.7 kg/hm2
