| Abstract: | 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 fertiliz-er is suitable for wide application in broccoli culture. |
