冬种马铃薯覆盖黑膜栽培试验

Cultivating experiment of winter potato by covering black plastic film

于2005年、2010年进行冬种马铃薯覆盖黑膜栽培试验,结果表明:黑膜栽培比传统的露地栽培马铃薯出苗时间提早了11 d,出苗到齐苗的时间缩短4 d;极显著提高了马铃薯茎叶生物量,显著提高块茎产量;提高大薯率,降低裂薯率。

Cultivating experiments of winter potato covering with the black plastic film were studied in 2005 and 2010.The results showed that,to compare with the control,the sprout time of winter potato covered black plastic film decrease by 11d;the time from sprout to complete emergence reduced by 4d;biomass of leaf and stem significantly increased;tuber yield significantly increased;rate of large tuber increased,and rate of cracked tuber decreased.
