施钼对花生氮代谢关键酶活性、氮素利用及产量的影响
Effects of molybdenum application on key enzyme activities of nitrogen metabolism,nitrogen utilization and yield in peanut
摘要
Abstract
To clarify the effect of molybdenum application on nitrogen metabolism enzyme activities and nitro-gen utilization in peanut,both pot and field experiments were carried out to investigate peanut enzyme activities of nitrogen metabolism,nitrogen accumulation,nitrogen use efficiency and yield in the key periods were investigated.Two molybdenum levels were used including control(0,no molybdenum)and molybdenum application(0.2 mg·kg-1).Results of both pot and field experiments revealed that,compared with control,molybdenum application signif-icantly improved activities of nitrate reductase,nitrite reductase,glutamine synthetase,and glutamate synthetase in root and leaves at pod setting and maturing stage of peanut.The molybdenum application significantly increased ni-trogen accumulation in root,shoots and pods,nitrogen uptake and use efficiency and pod yield.The nitrogen uptake efficiency in 2 growth periods of pod and field experiments was increased on average by 47.79%and 21.65%,and nitrogen use efficiency was increased on average by 10.58%and 13.56%,respectively.The peanut pod yield in-creased by 38.20%and 25.81%,respectively,under the increased molybdenum application compared with control.Consequently,molybdenum fertilizer could significantly improve enzyme activities related to nitrogen metabolism in peanut roots and leaves,and thus significantly improve the nitrogen accumulation,nitrogen uptake and utilization ef-ficiency and yield of peanut.Application molybdenum fertilizer might be an effective measure to improve peanut yield and nitrogen use efficiency.关键词
