摘　　要：[目的]研究腐植酸、聚天冬氨酸对西兰花生长的影响,为其施肥应用提供依据。[方法]采用田间试验,研究不同浓度的腐植酸、聚天冬氨酸与复合肥混施及两者复配与复合肥混施对西兰花生长、产量及品质的影响。[结果]0.5%腐植酸+0.3%聚天冬氨酸+复合肥复配处理较其他处理最好,可分别使西兰花株高、茎粗及产量增加8.3%、13.3%和10.3%,花球单重达478 g,商品率达89.4%,并且较1.0%腐植酸+0.6%聚天冬氨酸+复合肥复配处理经济成本低。[结论]0.5%腐植酸+0.3%聚天冬氨酸+复合肥复配施肥适宜西兰花种植推广。[ Objective ] To analyze the affects of humic acid and PASP on the growth of broccoli and provide the basis for fertilizer application. [ Method] Field experiments were conducted to study broccoli growth ,yield and quality ,when humic acids and PASP were used as fertilizer syner- gist for mixed with fertilizer. [ Result] The results showed that ：the treatment of 0.5% humic acid ＋ 0.3% PASP ＋ compound fertilizer is the best treatment,which can make broccoli plant height,stem diameter and yield increased by 8.3% ,13.3% and 10.3% ,respectively. The flowers single ball and commodity rate of 478 g and 89.4% ,and compared with the treatment of 1.0% humic acid ＋ 0.6% polyaspartate ＋ compound fertilizer low economic cost. [ Conclusion] 0.5% humic acid ＋ 0.3% polyaspartate ＋ compound fertilizer is suitable for planting broccoli pro- motion.
