摘要
在植物生长期,叶面喷施3‰尿素、5‰KH2PO4、5‰(NH4)2HPO4和3‰尿素+5‰KH2PO4等不同浓度及其组合的追肥,对地被月季‘恋情火焰’的生长、花径、单株开花量及分枝数等进行了研究。结果表明:生长期喷施磷、钾肥料较CK均能促使植株生长健壮,枝条粗壮,抗性增强,花繁色艳,花径大,单株开花量多且花期延长。其中,以3‰尿素+5‰KH2PO4混合追肥效果最为显著,与其他处理相比,枝蔓长、花径、单株开花量、分枝数均差异显著。
The effect of foliage spray with urea, KH2PO4 and （NH4）2 HPO4 at different concentrations and combinations on the growth, flower diameter, flower numbers per plant and branch numbers were studied. The results branch indicated ing,resistance, flower color,flower diameter, flower numbers per plant and flowering period. Among dif ferent treatments, the treatment of urea＋ KH2 PO4 was the best.
