| 摘 要： | 为筛选出比较适合东北温室水培莴苣生长发育的营养液浓度,采用浮板式水培的方法,以美国大速生菜为材料,试验设3个处理、1个对照、3次重复,研究在莴苣生长发育过程中,不同浓度营养液对莴苣的株高、根重、叶重和干重的影响。结果表明:EC值为2.6mS.cm-1的营养液浓度比较适合莴苣生长。

| Abstract: | In order to select more suitable concentration of nutrient solution for greenhouse hydroponic lettuce growth,the floating plate hydroponic method was used,the United States big speed lettuce was taken as test material,the test of 3treatments,1control repeated,3times,was conducted.The effect of different concentrations of nutrient solution on stem length,root weigh,leaf weight and dry weight during growth period was studied.The results showed that the EC value of 2.6mS.cm-1 in nutrient solution concentration was more suitable for the growth. |
