| 摘 要： | 研究包膜磷酸二铵及其配施黄腐酸对小麦产量和土壤养分供应强度的影响,可为其科学施用提供依据。以磷酸二铵(P,150 kg hm-2(以P2O5计,下同))、磷酸二铵减磷20%(P80%,120 kg hm-2)处理为对照,通过小麦(Triticum aestivum L)盆栽试验,研究了包膜磷酸二铵(CP)及其减磷20%(CP80%)、磷酸二铵配施黄腐酸(P+FA)及其减磷20%配施黄腐酸(P80%+FA)、包膜磷酸二铵配施黄腐酸(CP+FA)及其减磷20%配施黄腐酸(CP80%+FA)处理对小麦产量及其构成、各生育期株高、叶绿素相对含量、土壤pH及速效养分的影响。结果表明,CP、P+FA、CP+FA较等磷量P处理分别提高小麦产量7.7%、5.1、24.0%(p0.05),肥料磷素当季利用率分别提高9.14、9.74、17.00个百分点,净收益增加6.3%、1.1%、22.5%;减磷20%时,CP80%、P80%+FA、CP80%+FA处理较P处理分别提高小麦产量10.6%、7.2%和4.8%(p0.05),肥料利用率分别提高19.88、18.53和11.54个百分点,CP80%、P80%+FA处理经济效益显著提高8.54%和10.42%,CP80%+FA处理收益持平。磷酸二铵包膜及配施黄腐酸均可提高小麦各生育期土壤有效磷含量,不同施磷处理对土壤中无机氮和速效钾的含量无显著影响,可满足小麦整个生育期对氮素和钾素的需求。本研究条件下,包膜磷酸二铵配施黄腐酸有效增加了小麦产量和经济效益、提高了磷肥利用率和土壤养分供应强度,减磷20%依然增产或稳产。
