Abstract:
Taking Yong’an red lettuce as test material, effect of foliar spraying different concentrations of chlormequat on plant characters and growth of red lettuce were studied in the 3 growth stages. The results showed that in the processing level test set with chlormequat 600 times liquid spraying in early rosette inhibited lettuce stems elongation, increased the most obvious effect of stem diameter, so that each part of the thickened stem was uniform, plant squat real, which could improve the appearance quality of lettuce.The interaction effect of concentration and application time on plant height was not obvious, but the effect on stem diameter and yield per plant was significant, and timely spraying chlormequat affected perimeter lettuce stem mainly,yield was affected by the increasing of stem perimeter.It’s an important measure to get high yield of lettuce by spraying chlormequat timely.
