非交换性钾

我国北方主要土壤非交换性钾释放速率的研究

Release rates of non-exchangeable potassium in selected soils from northern China

结果表明，土壤速效氮（AN）、土壤速效钾（AK）和非交换性钾（NEK）含量随小麦生育进程呈现有规律的变化；

The content of soil available N , available K and non-exchangeable K changed regularly with wheat growth .

山东主要土壤供钾能力和非交换性钾释放的研究

Soil Potassium Supplying Capacity and release of non exchangeable potassium in Shandong soils

不同施肥处理土壤非交换性钾的释放量与缓效钾的含量有着极显著正相关关系。

The amount of non-exchangeable K released were highly correlated with their slowly-exchangeable K contents .

结果表明，供试土壤非交换性钾释放特性和有效性与粘土矿物密切相关。

The results showed that the releasing characteristics and availability ofnonexchangeable K related remarkably to clay minerals .

同时也说明了层间钾（非交换性钾）的释放对作物钾素供应起了重要作用。

Results also showed that the release of interlayer K ( non-exchangeable K ) played an important role in potassium supply to the plants .

土壤非交换性钾和矿物钾是冬小麦吸收钾素的主要来源。

Soil non-exchangeable K ( NEK ) and mineral K ( MRK ) were the main sources from which the absorbed K was in wheat .

在不同钾水平条件下，它们吸收利用土壤中的钾大部分来自非交换性钾源，其中矿物钾差异比较显著。

For different K levels , the most part of K absorbed by wheat is obtained from non exchangeable sources , among which the difference for mineral potassium is of relatively more significant .
