| 摘 要： | 以无限生长型番茄‘丰收’为试材,以椰糠∶珍珠岩=3∶1为基质,设置EC值为1.5、2.0、2.5、3.0、3.5、4.0 mS·cm^-1的6种营养液浓度,研究了在不同EC值营养液处理下植株的株高、茎粗、叶片数的生长变化,根系活力、可溶性糖、有机酸、可溶性蛋白质、维生素C含量、产量、干鲜质量、水分利用效率和根区液养分离子浓度等的变化。结果表明:适当提高营养液浓度可以改善番茄品质,但营养液浓度过高盐分累积严重时会导致产量和品质下降。EC值为2.5、3.0、3.5 mS·cm^-1的营养液较适合椰糠复合基质栽培,其中EC值为4.0 mS·cm^-1可作为短期内高品质栽培使用,番茄长季节高产栽培则可以选择EC值为2.0 mS·cm^-1的营养液。

| Abstract: | Six nutrient solution concentrations(1.5,2.0,2.5,3.0,3.5,4.0 mS·cm^-1)were set up according to different EC values,using tomato‘Fengshou’with indeterminate growth habit as the test materiall and coconut bran∶perlite=3∶1 as matrix.The change of plant height,stem diameter,leaf number,root activity,soluble sugar,organic acid,soluble protein,vitamin C content,yield,dry and fresh weight,water use efficiency and nutrient concentration in root zone were studied under different nutrient solution concentrations.The results showed that the quality of tomato could be improved by properly increasing the concentration of nutrient solution,but the yield and quality would decrease if the concentration of nutrient solution was too high and the salt accumulation was serious.When the EC values were 2.5,3.0,3.5 mS·cm^-1,the nutrient solution with EC value of 4.0 mS·cm^-1 could be used for short-term high-quality cultivation,while the nutrient solution with EC value of 2.0 mS·cm^-1 could be selected for long-term high-yield cultivation of tomato. |
