摘要
[目的]筛选肥料增效剂聚天门冬氨酸对玉米生长的最适宜添加量。[方法]以玉米先科11号为供试材料,通过盆栽试验,研究不同浓度的聚天门冬氨酸添加到液体肥料后对玉米生长、肥料利用效率的影响。[结果]液体肥料中添加不同浓度的聚天门冬氨酸对玉米株高、生物量以及氮磷钾养分积累量等都具有明显的影响,有利于玉米的生长发育,同时提高肥料利用效率。[结论]在液体肥料中添加1%的聚天门冬氨酸处理效果最为显著。
[Objective] The experiment was aimed to select the most suitable levels of polyaspartic acid as synergist on maize growth. [Method]Taking maize variety Xianke 11 as test material,a pot experiment was conducted to investigate the effects of different levels of polyaspartic acid with liquid fertilizer on maize growth and fertilizer use efficiency. [Result]Different concentration levels of polyaspartic acid with liquid fertilizer had positive effects on the maize height,biomass and N,P and K accumulation. They were advantageous to increase maize growth. Meanwhile,they could improve fertilizer use efficiency of maize. [Conclusion]The treatment applying 1% polyaspartic acid with liquid fertilizer showed the best performance.
