There was no significant correlation between root biomass and soildischarge rate of N2O.
土壤排放N2O速率与根系生物量没有明显的相关关系。

Soil heat flux from atmosphere to soil is about 5% of net radiation on a clear and cloudy day and soildischarge energy to atmosphere on a rainy day above the same field.
在晴天和阴天大气向土壤的能量传输均维持在净辐射的5%左右，雨天时，土壤热通量为负值。

Field experiments was used to study the change of soil N2O discharge flux in the northwestern arid and semi-arid areas.
