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。

Abstract: 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.

Key words: Tomato, Nutrient solution, Vegetative growth, Rockwool Culture
