为考察复合肥料中添加不同肥料增效剂(A、B、C)对玉米苗期生长指标及生物量的影响,开展了盆栽试验,测定了不同施肥处理的玉米株高、茎粗、叶片叶绿素相对含量(SPAD值)及生物量。结果表明:复合肥料中添加增效剂C处理的苗期玉米株高、茎粗及地上部、地下部鲜质量和干质量均优于其他施肥处理的;不同施肥处理的SPAD值无显著性差异。增效剂C可以促进玉米的生长发育,增加生物量。
A pot experiment is conducted to investigate the effects of adding different fertilizer synergists (A, B, C) to compound fertilizer on the growth indicators and biomass of maize at the seedling stage. Plant height, stem diameter, chlorophyll relative content (SPAD value) in leaves, and biomass under different fertilization treatments are measured. The results show that the treatment with synergist C added to the compound fertilizer have superior plant height, stem diameter, and fresh and dry weights of both above-ground and below-ground parts comparing with other fertilization treatments. No significant differences in SPAD values are observed among the different fertilization treatments. Synergist C can promote the growth and development of maize and increase its biomass.
