石灰性土壤条件下灌溉水中HCO3和不同HCO3水平对菜豆的生长及吸收利用土壤有效养分的影响进行了盆栽和水培试验。结果表明，在该土壤条件下以HCO3-含量较高的水进行灌溉明显降低菜豆对土壤养分的吸收利用能力，抑制养分向叶和果荚的分配;HCO3-含量越高，影响也就越明显。钙可在一定程度上减轻HCO3-前不利影响。
The effects of HCO3 and HCO3 levels in irrigation water on the growth and absorption and utilization of soil available nutrients under calcareous soil conditions were studied in pot and hydroponic culture. The results showed that irrigating water with high content of HCO3- under this soil condition significantly reduced the absorption and utilization of soil nutrient and inhibited the distribution of nutrients to leaves and pods. The higher the content of HCO3-, the more obvious the effect was . Calcium can reduce the adverse effect of HCO3-before to a certain extent.
