【摘要】 以"津优一号"黄瓜为试材,研究了1.5、2.2、2.5dS/m的不同EC值的营养液对温室黄瓜光合速率、单株叶面积、产量和果实水分含量的影响。结果表明:营养液的电导率对温室黄瓜叶片光合速率、株高、单株叶面积、产量和果实水分含量均有较大影响;当营养液电导率为2.5dS/m和2.2dS/m时光合速率、单株叶面积、产量和果实水分含量差异不显著,但显著大于营养液的电导率为1.5dS/m和营养液电导率为0.036dS/m(CK)。更多还原

【Abstract】 Used‘Jinyou No.1’ cucumber as experiment material,the effect of different electrical conductivity(EC)nutrient solution on leaves photosynthetic rate,yield and fruit quality were studied.The results showed that electrical conductivity of nutrient solution had a great effect on photosynthesis rate,plant height,leaf area of single plant,yield and fruit water content.No significant difference was found between T3 treatment(EC=2.5dS/m)and T2treatment(EC=2.2dS/m)about photosynthesis rate,yield and fruit water content but significantly bigger than T0(EC=0.036.5dS/m)treatment T1 treatment(EC=1.5dS/m).更多还原
