采用微型盆栽和大田试验，研究了赤城产Ｃａ－Ｋ型斜发沸石对盐化土壤有效钾的影响，以及斜发沸石在盐化土壤中的供钾能力和后效。结果表明：土壤速效钾含量随沸石施用量的增加而增加；土壤中施入铵态氮肥能促进沸石中钾的释出；将佛石一次施入盐化潮土中，在４ａ内土壤速效钾可增加５％～２５％。显然，Ｃａ－Ｋ型斜发沸石对土壤钾的供应具有调控作用。
The effects of Akagi-made Ca-K clinoptilolite on available potassium in salinized soil and the potassium supply and after-treatment of clinoptilolite in salinized soils were studied by using mini-pot experiments and field experiments. The results showed that the content of available potassium in soil increased with the increase of zeolite dosage. The application of ammonium nitrogen fertilizer in soil could promote the release of potassium in zeolite. Once applied to salinized alluvial soil, Can increase 5% ~ 25%. Obviously, Ca-K clinoptilolite has a regulatory effect on the supply of soil potassium.
