摘要
两年田间试验表明，覆膜栽培马铃薯具有明显的增产效应。覆盖处理的马铃薯出苗早；株高、叶面积、干物质积累、封行日期等群体质量指标明显优于对照；
The field experiment in several different plastic film mulching treatments was conducted from 1995 to 1996 The results showed that the treatments had considerable effects on increasing tuber yield of potato The quality indeces of potato population, such as plant height, leaf area index, dry-matter accumulation, interrow closed date in mulching treatments were clearly better than that of the control The percentage of large tuber and middle tuber in mulching treatments was higher than that of the control
