冬小麦田N_(2)O通量研究

N_(2)O Flux in Winter Wheat Field

采用箱式法在冬小麦田研究土壤植株N_(2)O通量的变化、季节变化,并且讨论土壤温度、水分对土壤N_(2)O通量排放或吸收的影响。在冬小麦田中各设计了2种不同的处理,分别使用小暗箱测量土壤N_(2)O通量,用明箱测量土壤—植物系统的N_(2)O通量。

The box method was used to study the variation and seasonal variation of nitrous oxide flux in soil plants in winter wheat field,and the effects of soil temperature and moisture on the emission or absorption of N_(2)O flux in soil were discussed.Two different treatments were designed in the winter wheat field.A small black box was used to measure the nitrous oxide flux in the soil,and an open box was used to measure the nitrous oxide flux in the soil-plant system.
