Abstract:: Taking cucumber ‘Lu cucumber No.3’ as material，which was poured root seaweed rooting agent fertilizer with different concentration (100，300，600 times) with water as control.The growth of plug-seedlings were measured in order to screen the most suitable concentration.The results showed that root grew stronger with the decrease of the seaweed rooting agent fertilizer dilution ratio.The peak appeared at 300 times treatment.Continued to reduce the dilution ratio，the increase of root growth and the root tip number were restrained，and SSI dropped significantly.The seedlings root absorption area and new roots number of 300 times treatment were above 36.58% and 133.39% respectively，compared with the control.Seedlings leaf chlorophyll content was significantly higher than the control.The treatment of pouring root seaweed rooting agent fertilizer promoted the plant height，stem diameter and leaf area.So，pouring root seaweed rooting agent fertilizer 300 times promoted seedling growth，and improved the quality of cucumber plug-seedlings.
