应用营养液培养的方法研究了P和HCO-3对水稻Zn吸收速率和Zn含量的影响。结果表明，P浓度在32－13μM范围内，P对水稻Zn吸收速率和Zn含量有轻微的促进作用，但超过130μM，P会降低水稻Zn吸收速率和Zn含量。一定的P水平下，增加Zn浓度可提高水稻Zn吸收速率。20和40mM的HCO-3严重抑制水稻根对Zn的吸收速率，与对照相比，水稻根的Zn吸收速率分别降低80％-90％和93％－99％。高浓度P和HCO-3共同抑制Zn的吸收，降低Zn的吸收速率。
The effects of P and HCO-3 on the Zn uptake rate and Zn content in rice were studied by nutrient solution culture. The results showed that the P concentration in the range of 32-13μM, P on the Zn absorption rate and Zn content of rice had a slight role, but more than 130μM, P will reduce the Zn absorption rate and Zn content of rice. Under a certain level of P, Zn concentration increased the Zn uptake rate of rice. HCO-3 at 20 and 40 mM significantly inhibited the Zn uptake rate in rice roots, which decreased by 80% -90% and 93% -99%, respectively, compared with the control. High concentrations of P and HCO-3 jointly inhibit the absorption of Zn, reducing the absorption rate of Zn.
