摘要
为合理开发和利用莴苣有机无机复混肥,采用田间小区试验,研究了有机无机复混肥对莴苣产量、品质及其生物指标的影响.结果表明:有机无机复混肥提高了莴苣的产量,增加了莴苣茎、叶中维生素C、可溶性糖含量,减少了硝酸盐和亚硝酸盐含量,使莴苣茎叶中粗纤维含量适中.且在莴苣生长过程中,有机无机复混肥提高了莴苣功能叶中的净光合速率和叶绿素含量,增强了莴苣功能叶中硝酸还原酶活性.
Studies on the effects of organic-inorganic complex fertilizers on yields,quality,biomarker of lettuce were carried out by field plot experiments.The result showed organic-inorganic complex fertilizers could increase the yield,vitamin C,soluble sugar contents.It could also decrease coarse fiber,nitrate and inferior nitrate contents.During the lettuce growth,the organic-inorganic complex fertilizers raised activities of NR in leaves of lettuce plant,added the chlorophyll in functional leaves and strengthened net photosynthetic rate in functional leaves of lettuce plant.
