Abstract
To study effect of humic acid liquid fertilizer(HALF)on the yield and quality of lettuces(Lactuca sativa),the treatment of chosing HALF as basal and topdressing fertilizers compared with the treatment of chosing compound fertilizer(CF)as basal fertilizer and urea as topdressing(control),through the random blocks field experiments design.The results indicated that compared with control and combining application of HALF and microelements as topdressing(T1),treatment of CF as basal fertilizer and HALF as topdressing(T1),the treatment of HALF as basal fertilizer and topdressing(T2),treatment of HALF as basal fertilizer had soluble sugar contents increasing by 20.8%,51.5% and 88.6%,and soluble protein contents by 13.9%,14.1%,38.7%,respectively.Under the same nutrient supplies,HALF increased soluble sugar and soluble protein contents,improved the quality of lettuces.Among all of the treatments,T3 was best.
