摘要
采用了秋季、顶凌、播种期三种不同时期覆膜方式,为干旱浅山区马铃薯全膜覆盖获得高产探索最佳覆膜方式,结果表明,秋季覆膜效果最好,比顶凌覆膜每公顷增产5061.8kg,商品率提高5.2%。顶凌覆膜比播种期覆膜每公顷增产4476.8kg,商品率提高1.1%。因此建议采用秋季覆膜方式,其次采用顶凌覆膜和播种期覆膜。
Film-covering in different time at autumn, dingling and sowing date to probe optimum mode in order to get high yield of potato in dryland, the results showed effect in autumn film-covering was best, the yield was increased by 5061.8kg·ha^-1 compared with dingling,commodity rate was increased by 5.2%. the yield in dingling film-covering was higher 4476kg ·ha^-1 than that of sowing date, commodity rate was increased by 1.1%, so autumn film-covering was suggested, secondly was dingling and sowing date .
