河北山前平原区不同小麦品种镉吸收差异研究
Characteristics of Cadmium Uptake in Different Wheat Varieties in Hebei Piedmont Plain
摘要
Abstract
To screen the wheat varieties suitable for planting in the Cd-contaminated farmland of Hebei Piedmont Plain,the field experiment was conducted to study the yield and differential characteristics of cadmium absorption of 48 local main wheat varieties.The results showed that there were significant differences in the yield and the ability to absorb and accumulate Cd among 48 wheat varieties(P<0.05).The yield of'Shimai 27'was the highest(10538.6 kg/hm2),which was 6.33%-42.41%higher than that of other wheat varieties.The yield of'Shimai 26'was the second highest,which was 6.77%-38.51%higher than that of other wheat varieties.The grain Cd contents and enrichment coefficients of'Shimai 26','Zhongxinmai 48','Malan 6'and'Kenong 2011'were relatively low,ranging from 0.115 to 0.133 mg/kg and from 0.032 to 0.038,respectively.The Cd transport coefficients of'Kenong 2011','Zhongxinmai 48'and'Shimai 26'were relatively low,ranging from 0.273 to 0.291.The results of cluster analysis showed that there were 2 varieties of low Cd accumulation,19 varieties with relatively low Cd accumulation,3 varieties with low Cd translocation,and 7 varieties with relatively low Cd translocation.By comprehensive evaluation of wheat yield,grain Cd content,enrichment coefficient and transport coefficient,'Shimai 26','Zhongxinmai 48'and'Kenong 2011'were identified as Cd low accumulation type wheat varieties for safe production in the Cd-contaminated farmland.关键词
