摘　　要：以岩棉为栽培基质，研究了不同单位浓度营养液对番茄营养生长的影响。结果表明，在营养生长时期，１．０单位标准浓度营养液（ＥＣ２．５０ｍＳ／ｃｍ）较０．５单位标准浓度营养液（ＥＣ１．４０ｍＳ／ｃｍ）有利于番茄营养生长和地上部与根部干物质积累。营养液处理２８天后，浇以０．５单位标准浓度营养液的番茄植株根系发生褐变，逐步坏死。试验还表明，岩棉培番茄地上部与根部生长高度相关。The experimental results showed that the vegetative growth and the dry matter accumulation of roots,and shoots in the tomato plant were increased by the 1 0 unit concentrated solution.Four weeks after treatment,the roots of the tomato plant watered in 0 5 unit solution were brown in color when compared with the roots of tomato plants grown in 1 0 unit solution.The experimental results also showed that there was a significant growth relationship between the root and the shoot.
