以两个生菜品种（弘农和绿领）为材料，研究了4种单株灌水定额处理（100mL ，75mL ，50mL 和25mL ）对生菜品质和矿质元素含量的影响。结果表明：随着灌水量的减少，生菜可溶性糖、可溶性蛋白、维生素C含量呈增加趋势。地上、地下部矿质元素含量呈降低趋势，其中N、K、Mg三种元素降低趋势明显，各处理之间差异显著。品种绿领地上部Ca元素含量在75mL灌水处理条件下显著降低，在50、25mL处理条件下又缓慢升高；品种弘农地下部Ca元素含量呈先增高后降低趋势。综合考虑，单株灌水量75mL可以保证生菜N、K、Ca、M g元素的代谢受到较轻的影响而又能兼顾保证较高的品质的最适灌水量。

This article investigeate the effects of different irrigation quantity (100mL ,75mL ,50mL and 25mL per plant)on the quality and mineral element content of two lettuce cultivars (cv .Hongnong and Loling ) .The results show that :soluble sugar ,soluble protein and vitamin C contents of lettuce tend to increase with the decrease of irrigation amount ;mineral element contents of upside part and underground part decrease ,of which three kinds of elements N ,K ,Mg decrease significantly ,and the differences are significant in each treatment ;Ca content of cv .L · ling decreases significantly in the 75mL irrigation conditions and decreases slowly under the treatment of 25mL and 50mL ;Ca content of cv . Hongnong underground firstly increases and then decreases . With a comprehensive consideration ,the metabolism of N , K , Ca and Mg of the lettuce will get lighter effects and also can give consideration to ensure a high quality of optimum irrigation at 75mL Irrigation per plant .
