摘　　要：为研究不同结球莴苣品种的养分吸收规律以及产量、品质差异,对7个结球莴苣品种的产量、养分吸收、营养品质、矿质元素含量和硝酸盐含量5类指标进行了测定评价。结果表明,不同结球莴苣品种养分吸收存在较大差异,产量和品质也有所不同。养分吸收对产量及品质有一定的影响,养分吸收较好的品种,其产量与品质也相对较好。7个品种中,亚特兰大和裕生2号的养分吸收量较好,其产量和品质也相对优于其他品种,综合表现佳;而养分吸收较差的飞翔,其产量及品质表现也比较差。In order to study the law of nutrient absorption by different head lettuce varieties and differences in their yield and quality,this paper measured and evaluated 5 indexes of 7 head lettuce varieties,including yield,nutrient absorption,nutrient quality,mineral substance content and nitrate content.The results indicated that there were bigger differences in nutrient absorption,yield and quality among different head lettuce varieties.Nutrient absorption has certain effect on yield and quality.Varieties with better nutrient absorption relatively had better yield and quality.Among these 7 varieties,‘Atlanta’and‘Yusheng No.2’had better nutrient absorption,and their yield and quality were relatively superior than that of the other varieties.Their comprehensive performance were also pretty good.Variety‘Feixiang’with poorer nutrient absorption had poor yield and quality performance.
