[目的]分析研究腐植酸、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]结果表明:5‰腐植酸+3‰聚天冬氨酸+复合肥复配处理较其它处理最好,可使西兰花株高、茎粗及产量分别增加8.3%、13.3%和10.3%,花球单重和商品率分别达到478 g和89.4%,并且较10‰腐植酸+6‰聚天冬氨酸+复合肥复配处理经济成本低。[结论]综上所述,5‰腐植酸+3‰聚天冬氨酸+复合肥复配施肥适宜西兰花种植推广。
[Objective] The research aimed to analyze the effects of humic acid and polyaspartic acid on the growth of broccoli and provide the basis for its fertilization application. [Method] The field experiment was conducted to study the effects of different concentrations of humic acid, polyaspartic acid and compound fertilizer on the growth, yield and quality of broccoli. [Result] The results showed that the treatment of 5 ‰ humic acid + 3 ‰ polyaspartic acid + compound fertilizer was the best than other treatments, which could increase the plant height, stem diameter and yield of broccoli by 8.3%, 13.3% and 10.3% %, Flower bulbs weight and commodity rate reached 478 g and 89.4% respectively, and the economic cost was lower than that of 10% humic acid + 6 ‰ polyaspartic acid + compound fertilizer. [Conclusion] In summary, 5 ‰ humic acid + 3 ‰ polyaspartic acid + compound fertilizer was suitable for the promotion of planting broccoli.
