Abstract：In order to explore the application effect of balanced fertilization technology on the continuous crop barrier of facility vegetables,this paper took lettuce as the experimental material,set up 7 different fertilization treatments,took conventional fertilization as control 1,drenching disinfection+no basal fertilizer as control 2,and researched the influence of different fertilizer treatments on the botanical characters and the yield of lettuce.The results showed that increased application of soil improved fertilizer substrate and bactericide could promote the increase of plant height,stem thickness and plant mass,and the yield of lettuce,was significantly higher than that of control 1 and control 2,with increases of 25.81%and 46.02%,respectively.Taken together,the effect of applying of 32 kg formulated fertilizer,10 kg compound mic-fertilizer,200 kg soil improved fertilizer substrate,5 kg bactericide had the best effect on the botanical characters and the yield of lettuce,it provided reference for the scientific production of lettuce ingreenhouses.
