| 摘 要： | 干旱是威胁宁南山区胡麻生产持续发展的首要限制因子.采用地膜覆盖穴播种植技术,探索了旱地胡麻覆膜穴播种植的增产机理及其增产效应.结果表明,覆膜穴播可以提高土壤地温,保持土壤水分,促进土壤速效养分的充分释放和有效利用.又因穴播种植,胡麻籽粒顶土合力增强,出苗率高达79.4%～96.2%,籽粒产量提高37.9%～46.2%.与此同时,作者于胡麻覆膜穴播种植后,在胡麻的关键生育期枞形后期-现蕾初期,进行了膜上节水补灌试验.结果表明,节水补灌300～450 m3/hm2可提高籽粒产量30%～44%,水分生产效率达0.30～0.32 kg/(hm2.mm),水分生产效率提高8%～14.9%.这一新的种植方式,效益显著,应在干旱半干旱地区的胡麻产地大面积推广应用.
