摘要
研究了珠江三角洲水稻田内六六六残留量和土壤氧化还原电位、pH值、阳离子交换容量、土壤容重、含水量、有机质含量之间的相关关系,并进行了通径系数分析,此外还对土壤中和糙米内六六六的残留量作了相关分析。结果表明土壤中六六六残留量对糙米中六六六β异构体的残留量有直接影响,但土壤中六六六的残留总量及其α、γ异构体的残留量受土壤理化性状的制约。
Study on the relations between the BHC content remained in the paddy soils of Zhujiang River delta and soil oxidation-reduction potential, soil pH, cation exchange capacity, volume weight, soil water content, soil organic materials and the corresponding BHC content remained in unpolished rice, was made by using the methods of correlation and path-coefficient analysis, The results showed that the remained content of BHC β-isomer in rice is only directly related to those remained in soils; but the total contet of BHC in soils and its α-, γ-isomer are restricted by the physical and chemical nature of the soils.
