有机肥供钾效果与土壤缓效钾关系较密切。
The effect on K supplying of organic fertilizer was more clearly related to soil slowly available K.
缓效钾的协同克立格法的插值精度高于普通克立格法。
The overall estimation of slow-release K quality by cokriging was superior to that by ordinary kriging.
雨强比坡度对土壤、缓效钾和速效钾的流失影响更大。
Rain intensity has more effect on the loss of soil, slowly available K, and rapidly available K than slope gradient.
坡度比雨量对土壤、缓效钾和速效钾的流失影响更大。
Slope gradient has more effect on the loss of soil, slowly available K, and rapidly available K than amount of rainfall.
单施氮肥的土壤，速效钾、缓效钾含量均降低，全钾含量变化不明显。
Available potassium and slow-released potassium contents were decreased, and total potassium content was changed insignificantly in the soil of mono-application of nitrogen fertilizer.
雨强（冲刷强度）增大，溶解态钾浓度，溶解态钾、缓效钾和速效钾流失量明显增加。
The concentration of dissolved K and amount of dissolved K, rapidly available K, and slowly available K lost in the runoff increase obviously with the increase of rain intensity.
结果表明：供试土壤施钾后不仅提高耕层土壤速效钾含量，而且也很快向缓效钾方向转化，转化量随钾肥用量的提高而增大。
The results showed that the application of potash could raise both the contents of the fast available K and the slowly-released K in soil.
