摘　　要：为探讨苯磺隆胁迫下生物质炭对谷子籽粒产量和营养品质的影响,以张杂谷10号和晋谷21号为研究对象,采用二因素完全随机区组设计,设置不同生物质炭浓度(0、2%)和苯磺隆施用量(113、225、450 g/hm2),以不施苯磺隆为对照,共8个处理,分析苯磺隆胁迫下添加生物质炭对谷子籽粒产量和营养品质的影响。结果表明,与不添加生物质炭相比,添加生物质炭后2个谷子品种籽粒产量分别显著增加了10.50%、20.26%,且张杂谷10号的产量显著高于晋谷21号;张杂谷10号与晋谷21号籽粒中钾含量、维生素C含量以及可溶性总糖含量在添加生物质炭后显著上升,与不添加生物质炭相比,分别提高了18.68%、1.38%,6.92%、13.08%,22.29%、3.31%;张杂谷10号籽粒磷含量均在苯磺隆施用量为113 g/hm2时达到最大值,晋谷21号添加生物质炭后,籽粒磷含量与粗脂肪含量均表现出下降趋势。添加生物质炭后,喷施苯磺隆与不施苯磺隆相比,2个谷子品种籽粒氮含量分别显著提高了3.79%、4.62%。因此,施用生物质炭可在一定程度上缓解苯磺隆胁迫对谷子产量和营养品质的影响,试验的最佳处理组合为2%生物质炭配施113 g/hm2苯磺隆。To investigate the effect of biochar on yield and nutrient quality of millet grain under tribenuron-methyl stress,in this study,Zhangzagu 10 and Jingu 21 were used as the study subjects,using a two-factor completely randomized block design with different biochar concentrations(0,2%) and the amounts of tribenuron-methyl(113,225,450 g/ha),taking no tribenuronmethyl as a control,a total of 8 treatments were set to analyze the effect of addition of biochar on yield and nutrient quality of millet grain under tribenuron-methyl stress.The results showed that after the addition of biochar,the grain yield of two millet varieties significantly increased by 10.50%and 20.26%compared with that without adding biochar,and the yield of Zhangzagu10 was significantly higher than that of Jingu 21.The content of potassium,vitamin C,and soluble sugar in the grains of Zhangzagu 10 and Jingu 21 increased significantly after adding biochar,which increased by 18.68%and 1.38%,6.92%and13.08%,22.29%and 3.31%;The phosphorus content in the grais of Zhangzagu 10 reached the maximum when the spray concentration of tribenuron-methyl was 113 g/ha.After the addition of biochar in Jingu 21,the phosphorus content and crude fat content in the grains showed a decreased trend.After the addition of biochar,in the treatments of spraying tribenuron-methyl,the nitrogen content in the grains of the two millet varieties significantly increased by 3.79%and 4.62%compared with that in the treantment of no spraying tribenuron-methyl.Therefore,the application of biochar could alleviate the impact of tribenuronmethyl stress on millet yield and nutritional quality to a certain extent.The best treatment combination for this test was 2%of biochar with 113 g/ha of tribenuron-methyl.
