不同用量的营养液对生菜阳台基质栽培的影响摘要：本研究以常见的阳台蔬菜种类—生菜作为研究对象，考察不同用量的日本园试营养液对生菜阳台基质栽培的影响，考察指标包括株高、茎粗、叶绿素和 Vc 含量。研究结果表明，在 1/2 ~1/6 稀释浓度范围内，营养液稀释浓度的提高有助于生菜的生长，株高、茎粗、叶绿素和 Vc 含量均随营养液稀释浓度的增加而增加，且 1/2 稀释浓度处理的生菜长势最好、叶绿素和 Vc 含量最高。关键词：生菜；阳台；基质栽培；营养液Effect of nutrient solution of different dosage on substrate culture of lettuce balconyAbstract:In this study, the common balcony vegetable species - lettuce was studied to investigate the effect of different doses of Japanese garden nutrient solution on the substrate of lettuce terrace. The indexes included plant height, stem diameter, chlorophyll and Vc content. The results showed that the growth of lettuce was promoted by the increase of the concentration of nutrient solution in the concentration range of 1/2 to 1/6, and the plant height, stem diameter, chlorophyll and Vc contents increased with the increase of nutrient solution concentration , And the lettuce treated with 1/2 dilution had the highest growth potential with the highest content of chlorophyll and Vc.Key words: lettuce; balcony;substrate;nutrient solution目录1 材料与方法......................................................................................................11.1 试验材料和地点.....................................................................................11.2 试验方法.................................................................................................11.2.1 无土基质选择与配制....................................................................11.2.2 营养液选择与配制........................................................................11.2.3 种子处理与播种..................................................................
