| 摘 要： | 芝麻土壤施镉的小区试验结果表明,土壤中镉低于1.2ppm有增产作用,高于2.0ppm则产生危害,土壤镉含量与芝麻籽粒产量和生物学产量符合一元二次方程。芝麻减产15％的土壤镉临界浓度为16ppm,籽粒镉含量达到食品卫生标准的土壤镉临界值为0.6ppm。植株镉累积系数为:根(1.13)>茎(0.84)>叶(0.45)>籽实(0.23)。大田植株镉累积系数为:根(1.35)>茎(0.61)>叶(0.39)>籽实(0.28)。芝麻年吸镉率为土壤镉的0.157％。

| Abstract: | Field cultural experiments showed that low content of cadmium(<1.2ppm)could increase sesame yield while high content decreased growth and yield.There were two interrelated square equations between content of cadmium in soil and yield of sesame seed and biomass output of sesame.A content of cadmium in soil of 16ppm could reduce sesame yield by 15%,and when the content in sesame seed came up to the standard of food sanitation,the corresponding soil content was 0.6ppm.Field cultural experiements showed that cadmium accumulation coefficient in sesame in root,stem,leaf and seed were 1.13,0.84,0.45,0.23 respectively |
