摘要
Abstract
Objective:To determine the optimum amount of fertilization of biennial Glycyrrhiza uralensis Fisch.in semiarid regions of Middle of Gansu province; Methods: Single-factor randomized block design was appied in the study.Results:With the increase of diammonium phosphate fertilizer rate,the yield,glycyrrhizic acid and liquritin,rose at first and dropped afterward;when diammonium phosphate was 224.89 kg·hm -2 ,licorice economic output was 3912 kg·hm -2 , glycyrrhizic acid and liquritin were 1.45% and 0.80%,respectively.The potassium chloride dosage of 149.93 kg·hm2 was optimal,its economic output,contents of glycyrrhizic acid and liquritin was 5480 kg·hm -2 , 1.40% and 0.65%, respectively.Conclusion:Fertilization can play a distinct accelerating role on yield of licorice,but the application of potassium chloride leads a reduction in chlorice quality.关键词
