| 摘 要： | 采用８种不同的营养液对生菜进行砂培试验，结果表明，不同的营养液配方对生菜的生长发育、产量及品质的影响差异很大．其中以Ⅰ号配方的产量最高，叶面积最大，叶片数最多，而硝酸盐含量及重金属离子含量较低，故Ⅰ号配方较好．试验还表明，生菜中Ｎ，Ｐ，Ｋ的含量与配方中的Ｎ，Ｐ，Ｋ含量呈正相关。Ⅰ号配方的不同浓度试验结果，以Ｃ处理产量最高，Ａ处理次之，但最适浓度尚有待进一步研究确定．

| Abstract: | By pot experiments on sand culture of lettuce,using eight kinds of nutrient so-lutions, it shows that different nutrient solutions'formula has different effects on lettucegrowth, yield and quality. Among them,treatment I formula is the best, has the highestyield for it,the biggest leaf area and the great number of leaves,what's more,the contents ofnitrate and trace metals are extremely lower. The results also show that the N,P,K contentsof lettuce are positive correlation with that of nutrient solutions.The experiments on the nu-trient solutions concent rations of treatment I also show that the treatment C has the high- est yield of lettuce,then treatment A.Anyway,the most suitable concentration of nutrientsolutions will be further studied. |
