摘要：

为筛选出适宜河北山前平原区Cd污染农田种植的小麦品种，通过大田微区试验，对河北省48个小麦主栽品种的产量和Cd吸收差异特征进行研究。结果表明，48个小麦品种间产量和Cd吸收积累能力存在不同程度的差异(P<0.05)。‘石麦27’产量最高，为10538.6 kg/hm2，较其他小麦品种高出6.33%~42.41%；其次是‘石麦26’，较其他小麦品种高出6.77%~38.51%。‘石麦26’、‘中信麦48’、‘马兰6号’和‘科农2011’籽粒Cd含量和富集系数均相对较低，分别在0.115~0.133 mg/kg和0.032~0.038之间。‘科农2011’、‘中信麦48’、‘石麦26’的Cd转运系数均较低，在0.273~0.291之间。通过聚类分析确定Cd低累积类型品种2个、较低累积类型品种19个；Cd低转运类型品种3个，Cd较低转运类型品种7个。综合评价小麦产量、小麦籽粒Cd含量、富集系数、转运系数等指标，初步确定‘石麦26’、‘中信麦48’和‘科农2011’可以作为Cd低累积型小麦品种用于河北山前平原区镉污染农田安全生产。研究旨在为轻中度Cd污染耕地的安全利用提供科学依据。

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.
