【摘要】 研究了不同水平外源氯处理对番茄(LycopersiconesculentumL.)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(6·25~100nmol·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、300mmol·L-1Cl-处理的幼苗干物质积累极显著下降。更多还原

【Abstract】 Potassium, magnesium, phosphorus uptake 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.更多还原
