Abstract

Abstract:

Considering the current situation of boron deficiency characteristics of acid soil and high risk of heavy metal pollution in South China, this paper aimed to provide data support for how to ensure the high-quality and safe planting of agricultural products on boron deficient soil and the effective utilization of agricultural waste resources. In this study, silkworm excrement was used as soil conditioner, and combined with exogenous boron addition to carry out compound regulation, so as to explore its effects on the soil physical and chemical properties and the contents of available heavy metal Cd and Pb in the compound polluted soil. The results showed that the addition of 2% and 6% silkworm excrement could significantly increase the soil pH value by 49.5% under different boron treatments. Additionally, the physical and chemical properties of soil such as soil organic matter, alkali hydrolyzable nitrogen, available phosphorus, available potassium and available boron were also significantly improved. However, the effect of different silkworm excrement addition on the soil available heavy metal concentrations was related to the types of elements. For the available Cd concentration, it was not affected significantly by the different addition of silkworm excrement fertilizer, while the available Pb concentrations could be remarkably decreased. In the compound polluted soil with 6% silkworm excrement fertilizer, the soil available Cd concentration was increased by the addition of 0.5 mg∙kg^-1 boron comparing with the treatment without boron addition, and then decreased significantly when the boron addition was 2.0 mg∙kg^-1. Under the treatments without or with 2% silkworm excrement addition, there was no significant difference in the soil available Cd concentrations between different boron addition levels. On the other hand, both of the two silkworm excrement additions could significantly reduce the soil available Pb concentrations compared with that without silkworm excrement fertilizer, and the reduction was up to 98.9%. The interaction analysis of different factors showed that the two factors of “boron+silkworm excrement fertilizer” had a certain interaction effect on the soil available Cd and Pb, and its influence was greater than that of single boron treatments, but the single silkworm excrement treatment had a greater influence on the soil available Cd and Pb concentrations than the two above-mentioned treatments. The conclusions obtained in this study would provide a scientific reference for the utilization of agricultural waste resources, reducing the bioavailability of soil heavy metals and improving the productivity of agricultural land.

摘要：

针对华南地区酸性菜地土壤缺硼特性和重金属污染风险较高的现状,为解决如何保障缺硼土壤上的农产品高品质安全种植和农业废弃物资源的有效利用等问题提供数据支撑。以蚕沙为土壤调理剂,结合外源硼添加进行复合调控,探讨其对铅镉复合污染土壤的土壤理化性质、重金属铅镉有效态含量的影响。结果表明,2%和6%的蚕沙添加量在不同硼处理下都能使土壤pH值显著提高,增加幅度达49.5%;使土壤有机质、碱解氮、有效磷、速效钾和有效态硼含量等土壤理化性质也得到明显改善。而不同蚕沙添加量对土壤重金属有效态含量的影响效果与元素类别有关,其中对有效态镉含量的影响效果并不显著;对有效态铅含量的降低效果则十分显著。在铅镉复合污染土壤上进行蚕沙复合硼的处理表现为,在6%蚕沙添加量下,0.5 mg∙kg^-1硼添加处理使土壤有效态镉含量较未添加硼时有所增加,而当硼添加量为2.0 mg∙kg^-1时,土壤有效态镉含量又显著下降;而其他蚕沙添加量处理下,土壤有效态镉含量在复合不同硼处理之间无明显差异。就土壤有效态铅含量而言,两种蚕沙添加量均使其较未加蚕沙时明显下降,降低量达98.9%。对不同因素的交互效应分析可见,“硼+蚕沙”二因素对土壤重金属有效态镉和铅含量存在一定的交互效应,且其影响作用大于单一硼处理,但单一蚕沙处理相对上述两种处理对土壤有效态镉和铅含量的影响更大。该研究结果将为解决农业废弃物资源利用、降低土壤重金属的生物有效性和提升耕地生产力提供科学的参考依据。
