The relationship between mineralizable soil N and crop N uptake was studied under the condition of pot and field experoments respectively.
在盆栽和田间条件下，研究了作物吸氮与土壤可矿化氮的关系。
The content of mineralizable nitrogen (MAN), total nitrogen (TN) and organic matter (OM) at different depth of soils were analysed to study the relationships between these three indices and crop uptake of nitrogen (CUN).
在具有典型半干旱气候特征的陕西永寿选取6种不同肥力水平的田块,分层采集0～100cm土样,测定各土层可矿化氮、全氮及有机质含量,研究其与作物吸氮量之间的关系。
The effects of temperature,pH,shaking speed,m(C)/m(N) and concentration of NH+4-N on denitrification of YY4 bacterium were investigated.
