摘要: 研究了不同配方及相同配方不同剂量营养液对新几内亚凤仙生长发育的影响。结果表明:处理7有利于新几内亚凤仙的营养生长;处理2有利于新几内亚凤仙的生殖生长;在12‰~24‰营养液浓度之间存在着造成新几内亚凤仙出现盐害的临界值,在此值之下,鲜重增量、株高、侧枝数、侧枝总长四项指标都随盐分浓度的增加而增大。

Abstract: The effects of different nutrient solutions and concentrations on the growth and development of Impatients hawkerri were discussed in this paper.The results indicated that treatment 7 had the best influence on the growth of I.hawkeri, treatment 2 was suit for the development of I.hawkeri and the critical value of salt that caused injury to I.hawkeri was between 1.2‰- 2.4‰. Under this critical value,the fresh weight,height of plant,number of branches and total length of branches raised with the increasing of nutriet solution concentration.

Key words: Nutrient solution, Impatiens hawkeri, Growth, Development
