  • 摘要: 南方水稻镉（Cd）污染是我国当前面临的主要环境问题之一。以中稻丰两优1号为材料，采用大田小区实验，研究了根区施加钙镁磷肥（P1：1 800 kg·hm-2、P2：3 000 kg·hm-2）、叶面喷施硅/硒（LS：2.0 mmol·L-1 Na2SiO3、LX：25 μmol·L-1 Na2SeO3、LSX：1.0 mmol·L-1 Na2SiO3+12.5 μmol·L-1 Na2SeO3）以及根区与叶面联合处理（P1LS、P1LX、P1LSX、P2LS、P2LX、P2LSX）下水稻对Cd的吸收。结果表明：1）根施钙镁磷肥显著降低了土壤有效态Cd含量（p1、P2较对照分别降低16.1%和29.5%；单独的根施钙镁磷肥或叶喷硅/硒处理后，稻米Cd含量较对照均显著降低（p1 40.8%、P2 57.2%、LS 42.3%、LX 35.0%、LSX 39.2%；根施钙镁磷肥与叶喷硅/硒联合调控对降低稻米Cd含量表现出显著的协同效应（p值显著性），其中P1LS、P1LX和P1LSX较单独的P1分别降低了61.2%、59.5%和68.2%，P2LS、P2LX和P2LSX较单独的P2分别降低了75.0%、54.2%和75.7%。2）Cd从秸秆向籽粒转运系数（SS）大于从根向秸秆转运系数（RS），根区与叶面联合处理明显降低RS和SS，并有显著的协同效应（p1与Si/Se联合，RS和SS平均降低了7.4%和22.0%，P2与Si/Se联合，RS和SS平均降低了16.0%和19.6%。3）从食品安全来说，单独的根施钙镁磷肥或叶喷硅/硒，大米Cd含量多数超标（国标0.2 mg·kg-1），而根区与叶面联合处理几乎都能实现Cd含量不超标，其中降幅最大的为P2LS 和P2LSX，稻米Cd含量不到0.09 mg·kg-1。因此，根施钙镁磷肥与叶喷硅/硒联合处理可显著降低水稻Cd吸收、保障稻米质量安全。
    Abstract: Contamination of rice with cadmium (Cd) in Southern China is a major environmental problem. A field experiment was conducted to investigate how Cd uptake by paddy rice (Fengliangyou 1) was influenced by the soil application of calcium magnesium phosphate (CMP), leaf spraying with Si/Se, or a combination of the two. The CMP treatments were P1 (1 800 kg·hm-2) and P2 (3 000 kg·hm-2). The leaf spraying treatments were LS (2.0 mmol·L-1 Na2SiO3), LX (25 μmol·L-1 Na2SeO3), and LSX (1.0 mmol·L-1 Na2SiO3 mixed with 12.5 μmol·L-1 Na2SeO3). The results indicated that CMP led to a soil exchangeable Cd that was lower by 16.1% and 29.5% under the P1 and P2 treatments, respectively, than that of the control (CK). Soil application of CMP or leaf spraying with Si/Se treatments alone led to Cd concentration in paddy rice that were lower by 40.8%, 57.2%, 42.3%, 35.0%, and 39.2% than that of the CK under treatments P1, P2, LS, LX, or LSX, respectively. The combined CMP/leaf spraying treatment had a significant synergistic effect. The Cd concentrations after the P1LS, P1LX, and P1LSX treatments were 61.2%, 59.5%, and 68.2%, respectively, higher than those after P1 treatment alone. In contrast, the Cd concentrations after the P2LS, P2LX, and P2LSX treatments were 75.0%, 54.2%, and 75.7% lower, respectively, than those after treatment with P1 alone. The Cd root-to-straw transport coefficient (RS) was larger than the straw-to-seed ratio (SS). The combined treatments exerted significant synergistic effects on the decrease in RS and SS (p1 and the leaf spraying (Si/Se) treatment was combined, RS and SS were reduced by 7.4% and 22.0% on average, while the P2 and leaf spraying (Si/Se) combination led to average declines in RS and SS of 16.0% and 19.6%, respectively. From a food safety viewpoint, the soil application of CMP or leaf spraying with Si/Se single treatments resulted in Cd concentrations in paddy rice that generally exceeded the national standard (0.2 mg·kg-1), but the combined treatments reduced the Cd concentration in almost all the paddy rice to below the standard. Of all the treatments, P2LS and P2LSX produced the largest reductions because the Cd concentration in paddy rice was less than 0.09 mg·kg-1. These results demonstrated that the combined root zone (CMP) and leaf blade (Si/Se) treatments could effectively reduce grain Cd concentration and ensure the safety of agricultural products.

摘要: 南方水稻镉（Cd）污染是我国当前面临的主要环境问题之一。以中稻丰两优1号为材料，采用大田小区实验，研究了根区施加钙镁磷肥（P1：1 800 kg·hm-2、P2：3 000 kg·hm-2）、叶面喷施硅/硒（LS：2.0 mmol·L-1 Na2SiO3、LX：25 μmol·L-1 Na2SeO3、LSX：1.0 mmol·L-1 Na2SiO3+12.5 μmol·L-1 Na2SeO3）以及根区与叶面联合处理（P1LS、P1LX、P1LSX、P2LS、P2LX、P2LSX）下水稻对Cd的吸收。结果表明：1）根施钙镁磷肥显著降低了土壤有效态Cd含量（p1、P2较对照分别降低16.1%和29.5%；单独的根施钙镁磷肥或叶喷硅/硒处理后，稻米Cd含量较对照均显著降低（p1 40.8%、P2 57.2%、LS 42.3%、LX 35.0%、LSX 39.2%；根施钙镁磷肥与叶喷硅/硒联合调控对降低稻米Cd含量表现出显著的协同效应（p值显著性），其中P1LS、P1LX和P1LSX较单独的P1分别降低了61.2%、59.5%和68.2%，P2LS、P2LX和P2LSX较单独的P2分别降低了75.0%、54.2%和75.7%。2）Cd从秸秆向籽粒转运系数（SS）大于从根向秸秆转运系数（RS），根区与叶面联合处理明显降低RS和SS，并有显著的协同效应（p1与Si/Se联合，RS和SS平均降低了7.4%和22.0%，P2与Si/Se联合，RS和SS平均降低了16.0%和19.6%。3）从食品安全来说，单独的根施钙镁磷肥或叶喷硅/硒，大米Cd含量多数超标（国标0.2 mg·kg-1），而根区与叶面联合处理几乎都能实现Cd含量不超标，其中降幅最大的为P2LS 和P2LSX，稻米Cd含量不到0.09 mg·kg-1。因此，根施钙镁磷肥与叶喷硅/硒联合处理可显著降低水稻Cd吸收、保障稻米质量安全。
