摘要
以早熟玉米新品种边单3号为试验材料,在12个不同施肥水平条件下,研究了氮、磷对边单3号玉米产量和主要农艺性状的影响。结果表明:边单3号玉米品种的产量随着氮肥和磷肥用量的增加先增后减,产量在N180 kg.hm-2、P90 kg.hm-2用量时达到最高,为10 568.44 kg.hm-2;株高、穗位高、百粒重、单穗粒重随着施肥量的增加先高后低,秃尖是先短后长,成熟期绿叶片数则呈逐步增加的趋势。
Taking new varieties of early maturing maize Biandan No.3 as experimental material,in 12 different fertilization conditions,the effect of nitrogen and phosphorus on maize yield and agronomic traits was studied.The results showed that：the Biandan No.3 maize yield was first increased and then decreased with the increasing of nitrogen and phosphate fertilizer,the amount of yield in the N 180 kg·hm-2、P 90 kg·hm-2 reached the highest level,for 10 568.44 kg·hm-2;plant height,ear height,100-kernel weight and kernel weight per ear increased as the increasing of fertilizer first high to low,the length of bald was the first short in length,number of mature green leaf slices increased with the gradual increase of fertilizer application.
