以莱阳孤芋为材料研究了4种栽培方式对芋头生长和产量的影响。结果表明，出苗天数3种覆膜栽培法均显著少于露地开沟栽培法，3种覆膜栽培法之间无显著差异。打孔覆膜栽培法的出苗率最高。生长前期3种覆膜栽培法的叶面积指数均显著大于露地栽培法，生长中后期起垄覆膜栽培法和打孔覆膜栽培法的叶面积指数显著大于另外2种栽培法。3种覆膜栽培法球茎产量均显著高于露地栽培法，打孔覆膜栽培法球茎的产量最高。

Effect of different culture way (furrow in the field, furrow withplastic mulch, hole with plastic mulch and ridge with plastic mulch) on growth and yield of Clocasia escalenta Schott was studied with cultivar "Laiyang Guyu ". The results showed that the germinate time of the three culture ways with plastic mulch were significantly short than furrow in the field. It was no significantly among the three culture ways with plastic mulch. The rate of germinate of hole with plastic mulch was the highest. In earlier stage of growth, the leef area index of the three culture ways with plastic mulch were significantly high compered with furrow in the field. The leef area index of hole with plastic mulch and ridge with plastic mulch were higher in middle and later stage. The tuber yield of the three culture ways with plastic mulch were significantly higher compered with furrow in the field, The tuber yield of hole with plastic mulch was the highest.
