摘要: 研究了不同水平外源氯处理对番茄(Lycopersicon esculentum L. ) 干物质积累、叶绿素含量、Cl- 、NO3- 、氮、磷、钾、钙和镁含量的影响。结果表明: 一定范围( 6.25~100 nmol·L - 1 ) 的外源氯处理, 不降低番茄生物量甚至促进生物量, 并可明显提高番茄幼苗对钾、镁、磷的吸收和氮素利用效率, 而200、300 mmol·L - 1 Cl- 处理的幼苗干物质积累极显著下降。

Abstract: Potassium, magnesium, phosphorus up take and nitrogen utilization efficiency of tomato seedlings was promoted while that biomass of plant was changeless or increased under supplemental Cl- treatments (6.25 - 100 mmol·L - 1 ). Dry matter accumulation of seedings treated with 200 and 300 mmol·L - 1 Cl-
was obvious less than that of the control.
