Effects of Humic Acid and PASP Compound Fertilizer Application on Growth, Quality and Yield of Broccoli.

腐植酸、聚天冬氨酸复配复合肥对西兰花生长、产量及品质的影响.

[Objective] This study was conducted to analyze the effects of humic acid and PASP on the growth of broccoli to provide a basis for fertilizer application. [Method] A field experiment was carried out to investigate broccoli growth, yield and quality by using humic acids and PASP as fertilizer synergists in the mixture with compound fertilizer. [Results] The treatment of 5‰ humic acid + 3‰ PASP + com-pound fertilizer exhibited the plant height, stem diameter and yield increased by 8.3%, 13.3% and 10.3%, respectively, and thus was the best; and the treatment showed a single curd weight of 478 g and a commodity rate of 89.4%, and had lower economic cost than treatment of 10‰ humic acid + 6‰ PASP + compound fertilizer. [Conclusion] In summary, 5‰ humic acid + 3‰ PASP + compound fertilizer is suitable for wide application in broccoli culture. [ABSTRACT FROM AUTHOR]

[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。 [ABSTRACT FROM AUTHOR]
