| 摘 要： | 研究从氮、磷、钾不同水平对灯盏花生长发育和光合色素含量的影响,探讨灯盏花的营养特点。结果表明：氮、磷、钾对灯盏花的生长发育的影响是不同的,其中氮对营养生长的影响最大,磷对植株的花期有较大影响,钾可明显促进根的生长。适宜的氮、磷、钾水平有利于灯盏花植株的旺盛生长和生物量的增加,过高过低都会影响其正常生长。合适的供氮水平可提高光合色素的含量,促进植株生长。

| Abstract: | The effects of different nitrogen, phosphorus and potassium levels on the growth development and photosynthetic pigment contents of Erigeron Breviscapus were studied. The results showed that N, P, K had different effects on the growth and development of Erigeron Breviscapus. N had the most important influence on the growth, P had the major effect on the flowering period and K promoted the root growth obviously. Only adequate N, P and K levels were suitable for the prosperous growth and the increase of biomass of Erigeron Breviscapus. Also moderate N supply could increase the photosynthetic pigment contents and promote the plant growth. |
