Abstract:: Taking 10 kinds of common leaf vegetables as test materials，through a pillar media cultivation mode，the influence of leaf vegetables yield per unit area was explored to screen high-yield varieties on this mode preliminarily.The results showed that though 45 days naturally growth to harvest，leaf vegetables yield were differences between different levels on the same pillar，from top to bottom layered production mainly had two kinds of change rule，the first increase after reduction and step by step a downward trend.On the cultivation experiment mode，Chinese cabbage，‘Jingyan’fast vegetable，coriander，fennel，floatingheart production were better than the other varieties，Chinese cabbage and fast vegetable yield was 14.15 kg/m2 and 11.08 kg/m2 respectively，coriander and fennel increased the yield per unit area by increasing the planting density，floatingheart grew faster，leaf length was larger than others，the floatingheart fresh weight was about 38% of Chinese cabbage，corresponding to its dry weight reached 92%.Yield of lettuce was the lowest，there was no significant difference between the ‘Naisheng No.1’ and ‘Xiangsheng No.3’varieties.
