[Results] The treatment of 5‰ humic acid ＋ 3‰ PASP ＋ compound fertilizer exhibited the plant height, stem diameter and yield increased by8.3%, 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.展开更多
