摘　　要：以13个当地推广种植的四季豆品种为材料,在黔西北地区L地与Y地的Cd污染耕地,采用田间小区试验研究不同品种四季豆Cd吸收富集差异,探讨品种与环境对其作用效应,并筛选出适宜黔西北地区种植的四季豆Cd低富集品种。结果表明,四季豆产量与Cd含量均受品种、环境及品种与环境互作的极显著影响。同一地点不同品种四季豆Cd含量差异显著,最高值(红皮秋紫架豆)与最低值(帮达二号)可相差10倍。L、Y两地不同品种四季豆对土壤Cd的富集系数分别为0.06%~0.50%、0.13%~0.93%,供试的13个品种四季豆Cd含量均表现为安全水平。13个四季豆品种中帮达二号产量最高,在L、Y两地分别达18513.6、19287.9 kg/hm^(2)。综上,13个四季豆品种均可作为黔西北类似Cd污染区安全生产的推荐品种,其中帮达二号因高产、低Cd含量等被优先推荐。In order to explore the differences in the absorption and enrichment of cadmium(Cd)by different kidney bean varieties and the effects of varieties and environment on them,and to screen out the Cd low-enriched kidney bean varieties suitable for planting in northwestern Guizhou,13 local kidney bean varieties were used as materials,and in the Cd-contaminated farmland of L site and Y site in northwestern Guizhou,a field plot experiment was conducted.The results showed that the variety,the environment and interaction between variety and environment had extremely significant effects on yield and Cd content of kidney bean,respectively.There was significant difference in Cd content of different kidney bean varieties in the same place.The maximum value of Cd(in Hongpiqiuzijiadou)and the minimum value of Cd(in Bangda No.2)could be 10 times different in the same place.The bioconcentration factor(BCFCd)of Cd in soils for different kidney bean varieties in L site and Y site were 0.06%—0.50%and 0.13%—0.93%,respectively.The Cd content of 13 tested kidney bean varieties showed the safe level.The yield of Bangda No.2 was the highest among the 13 varieties,reaching 18513.6 and 19287.9 kg/ha in L and Y sites,respectively.In summary,13 kidney bean varieties can be used as recommended varieties for Cd-contaminated areas in northwestern Guizhou,and Bangda No.2 was preferred because of its high yield and low Cd content.
