| 摘 要： | 研究了不同滴灌施肥强度对温室生菜生物学性状、生理指标、品质及产量的影响。结果表明:全生育期滴灌施肥强度为1350 m3/hm2肥水混合液(浓度0.4 g/L)时,生菜的球径、开展度和叶片数显著高于其它滴灌施肥强度,叶片叶绿素含量及最大光化学效率Fv/Fm有一定提高,生菜VC含量和净菜产量均达到最高水平,分别为1.65 mg/kg鲜重和46 178 kg/hm2。

| Abstract: | Biological traits,physiological indices,quality and yield of lettuce under different fertigation intensities in greenhouse were studied.The results showed that with the application of 1 350 m3/hm2 fertilizer solution(0.4 g/L),diameter of lettuce ball,extension,number of leaves were significantly higher than other fertigation intensities.Meanwhile,chlorophyll content and maximum photochemical efficiency Fv/Fm increased to a certain extent.Vitamin C content and net yield also reached the highest under this fe... |
