Abstract

Abstract: In this experiment, Citrus Huangguogan was used as the test material, and5 leaf area index (LAI) treatments were set. The fruit quality and production of each treatment were measured and analysed. With the decrease of LAI, single fruit weight, horizontal diameter, vertical diameter, total soluble solids, content of total sugar and sugar-acid ratio increased. Meanwhile, fruit shape index and content of Vc didn't differ significantly, and content of TA decreased significantly. The yield per mu increased first and then descend, simultaneously, the number of fruits per plant, and the yield per plant increased. T1 (2.0) was the appropriate LAI of Huangguogan, under which the yield was higher and the fruit quality was the best.
