| A pot experiment was conducted in artificially Cd-contiminated (1.7 mg/kg) soil to investigate the effects of
different soil amendments (lime, bentonite and microbial fertilizer) on contents of nutrient elements of soil and pakchoi
contaminated with cadmium. The results indicated that contents of soil alkali -hydrogen decreased significantly in all
treatments with amendments than that in CK. In the first batch, the total phosphrous contents in all treatments adding
amendments (except T7 treatment) were significantly higher than that in CK. The available phosphrous contents in all
treatments adding amendments (except T2 treatment) were significantly higher than that in CK. The available potassium
contents in all treatments adding amendments (except T1 and T5 treatments) were significantly higher than that in CK. In
the two batches, the total nitrogen content of pakchoi shoots in T1 treatment was significantly higher and total phosphorus contents of pakchoi shoots in T2 and T6 treatments were significantly higher than that in CK. In the first batch, the total potassium contents of pakchoi shoots in T1, T4 and T5 treatments were significantly higher than that in CK. |
