摘要
为研究微量元素对青贮玉米产量的影响,以确定青贮玉米产量的最优微肥组合方案,试验采用二次回归正交组合设计,研究了五种微肥Zn、Mn、Cu、B、Mo配合施用对青贮玉米产量的影响。通过主因素、单因素效应分析,结果表明:对青贮玉米产量有显著影响的因子是锌、硼和钼肥,有显著影响的交互项为锌肥与铜肥、锌肥与钼肥、锰肥与钼肥。定量地评价了五种微肥用量与青贮玉米产量的关系,提出了目标产量的最优微肥组合方案。从青贮玉米最大产量考虑得到其最优组合为:硫酸锌施用量28.75 kg/hm2,硫酸锰量10 kg/hm2,硫酸铜量30 kg/hm2,硼砂量5 kg/hm2,钼酸量0.93 kg/hm2。
The orthogonal combination design of quadratic regression was adopted in this experi- ment. Effects of interaction among Zn, Mn, Cu, B, Mo coordinating on the organism yield of silage maize were studied by field experiment. Effect of Zn, Mn, Cu, B, Mo on the organism yield of si- lage maize were studied quantitatively based on main and single factors effect analysis. The results show that the factors which have a significant impact on yield of silage corn are Zn, B and Mo, the interactions which have a significant impact on yield of silage corn are Zn and Cu; Zn and Mo; B and Mo. The range of Zn, Mn, Cu, B, Mo optimal composite scheme was 28.75 kg/hm^2 , 10 kg/ hm^2 ,30 kg/hm^2, 5 kg/hm^2, 0.93 kg/hm^2, respectively. This result provided an optimal composite scheme of Zn, Mn, Cu, B, Mo for the expected yield.
