摘　　要：研究不同覆盖物对冬种马铃薯产量及商品性状的影响,结果表明:3种覆盖物均可提早冬种马铃薯的出苗期、缩短生育期及提高出苗率,其中白膜效果最大;3种覆盖物均可增加马铃薯株高、茎粗,显著提高马铃薯的单株结薯数、商品薯率及块茎产量,其中黑膜效果最好;黑膜、白膜、稻草包芯的经济效益均显著高于对照。Effects of different mulching materials on yield and commodity value of winter-planting potato were studied. The results showed that, all three mulching materials could move up the emerging period of winter potato seedling, shorten the growth period and improve the germination rate; among which, the best effect was the white plastic mulching. All three mulching materials could obviously improve the plant height, stem diameter, tuber number per plant, commodity rate and to- tal tuber yield; among which, the best effect was black plastic mulching. Economic benefits of three mulching treatments were significantly higher than the control.
