西兰花花球对土壤汞的吸收富集规律方程数据

实验中，当西兰花种植地区土壤中重金属汞含量出现超标时，通过该吸收富集规律方程可以预测西兰花花球中重金属汞的含量，从而初步判断西兰花花球是否存在汞超标情况，指导农户更好开展西兰花种植，护航西兰花产品质量安全。将西兰花花球中汞含量记为b，通过检测实验中土壤中汞含量a, 获得公式：b = 0.003* a*a+ 0.0005a + 0.0048，最终可得出土壤中不同汞含量情况下西兰花花球中的汞含量。In experiments, when the heavy metal mercury concentration in the soil of broccoli cultivation areas exceeds the regulatory limit, the established absorption enrichment equation can be employed to predict the mercury concentration in broccoli florets. This allows for preliminary assessment of whether the mercury level in broccoli florets exceeds standards, enabling farmers to better conduct broccoli cultivation and safeguard the quality and safety of broccoli products. Let the mercury concentration in broccoli florets be denoted as b. By detecting the mercury concentration a in the soil during the experiment, the following formula is derived: b = 0.003*a² + 0.0005a + 0.0048. Ultimately, the mercury concentration in broccoli florets corresponding to different soil mercury levels can be obtained.
