对比研究了聚天冬氨酸增效复合肥和不同施用量普通复合肥在小麦上的应用效果,结果表明:施用聚天冬氨酸增效复合肥和普通复合肥都能通过增加有效穗数和每穗粒数,提高作物产量和经济效益,聚天冬氨酸增效复合肥增产增效作用更加明显。提高普通复合肥用量虽使产量和经济效益有所增加,但产投比与低施肥量持平,肥料利用效率甚至更低。适当降低施肥量可提高养分利用效率,减少肥料流失。聚天冬氨酸增效复合肥具有投入成本低、经济效益高的优势,在小麦生产上推广应用潜力巨大。
The effects of polyaspartic acid-enhanced compound fertilizer and common compound fertilizer with different application rates on wheat were compared. The results showed that the application of polyaspartic acid-enhancing compound fertilizer and common compound fertilizer could increase the number of effective panicles And grain number per spike, improve crop yield and economic benefits, polyaspartic acid synergistic effect of compound fertilizer more obvious synergistic effect. Although increasing the yield and economic efficiency of ordinary compound fertilizer increased, the ratio of input-output to production was low and the fertilizer utilization efficiency was even lower. Appropriate to reduce the amount of fertilizer can improve nutrient utilization efficiency, reduce fertilizer loss. Polyaspartic acid synergistic compound fertilizer has the advantages of low input cost and high economic benefit, and has great potential for popularization and application in wheat production.
