磷锌配施对玉米棒三叶叶绿素含量及超氧化物歧化酶活性的影响

Effect of Application of Phosphor and Zinc Fertilizer on Chlorophyll Contents and SOD Activities of Maize Three-ear-leaves

采用盆栽试验,研究了磷锌配施对玉米棒三叶叶绿素含量和超氧化物歧化酶活性的影响。结果表明:适当的磷锌配施能提高玉米棒三叶叶绿素含量和超氧化物歧化酶活性,其中磷贡献最大,交互效应次之,锌作用相对较小。从经济有益角度,在不施磷(P0)和P1水平下均以施锌肥大约80mg/kg土为宜,在P2水平下,以不施锌肥为宜。

A pot experiment was carried out to study the effect of phosphor and zinc fertilizer applied on chlorophyll contents and SOD activities of maize three-ear-leaves. The result showed that the chlorophyll contents and SOD activities of maize three-ear-leaves were increased of in proper proportion of phosphor and zinc, and as far as the contribution to the result, phosphor were the biggest, interaction took the second place, and zinc were smaller. At the P0 and P1 levels, 80mg zinc fertilizer in lkg soil was economical, and at the P2 level without zinc fertilizer was economical.
