中文摘要	采用二次通用旋转组合设计,在辽西半干旱区褐土上进行了长期田间试验,研究不同的灌水、施氮、施磷和施秸秆水平对土壤钾含量的影响.结果表明,土壤全钾含量随着氮、磷和秸秆施用量的增加而增加,随着灌水量的增加而降低,其中,施磷对土壤全钾含量的增加效果最明显,其次是施秸秆量.土壤速效钾含量随着灌水和氮、磷施用量的增加而降低,随着秸秆施用量的增加而增加,其中,施秸秆对土壤的速效钾含量影响最明显,其次是施用磷肥的影响.另外,施肥和灌水在提高土壤全钾含量的同时可能使速效钾含量降低,两者的变化表现为一定的负相关.
英文摘要	With quadratic regression general rotation design, a long-term field experiment was carried out in semi-arid area of western Liaoning, to study the effects of irrigation and fertilization on soil potassium content. The results showed that soil total K content increased with the increasing nitrogen, straw and phosphorus application, but decreased with the increasing quantum of water. The application of phosphorus had the most notable effect and the effect of straw was in the next place. Soil available K content decreased with the increasing water, nitrogen and phosphorus application, but increased with the increasing straw application. The application of straw had the most notable effect and the effect of phosphorus was in the next place. In addition, application of nitrogen and phosphorus may increase the content of soil total K but decrease the content of soil available K. The change of the two represented negative correlations.
