摘 要：
以牛厩肥、猪厩肥、麦秸和钾化肥为供钾源进行土培和生物试验,结果表明,麦秸对土壤的供钾能力及对作物的有效性均高于钾化肥,两种厩肥的供钾能力及钾素效果略低于钾化肥。随着厩肥和麦秸施用量的增加,土壤速效钾和缓效钾基本是成比例地增加,钾素有效转化率并未因施用量提高而明显降低。随着施用量的增加,玉米幼苗吸钾量呈增加趋势。

摘 要：
The soil cultural and biological experiments of different potassium sources (ox manure, pig manure, wheat straw and potassium fertilizer)were conducted. The results showed that the potassium supplying capability of K fertilizer was lower than that of wheat straw, but slightly higher than that of manures. Along with the increase of the application rate of manures and wheat straw, both the rapidly and slowly available K were increased , but the transformation rate of potassium did not decreased apparently. With the increase of K application rate, K absorption rate of corn seedlings was also increased.
