| 摘 要： | 以小青菜为试材,采用盆栽试验,喷施不同浓度硫酸亚铁溶液,研究铁肥对小青菜生物量及硝酸盐含量的影响。结果表明:在一定浓度范围内随着叶面喷施硫酸亚铁溶液浓度的增加,小青菜生物量显著增加,硝酸盐含量显著下降。浓度太高,小青菜生物量会显著下降,同时硝酸盐含量显著增加。

| Abstract: | Took qreenqrocery as material,by using the pot experiment,sprayed with different concentrations of ferrous sulfate to study the Fe fertilizer on greengrocery's biomass and nitrate concent.Results showed,the yield of greengrocery was increased significently and nitrate content decreased significantly with the increasing of spraying ferrous sulfate concentration.If ferrous sulfate concentration was too high the yield would be reduced and the nitrate content would be increased. |
