去年我们进行了春马铃薯单株高产栽培试验,试验材料共二十株,平均单株薯重八斤以上,最大单株薯重达十四斤。薯重十四斤的单株在收获时的长相是:地上部开展度二百厘米,主茎六个,分枝七十三个,叶色嫩绿,茎叶重十七点三斤;地下部结薯五十四个,三两以上大薯占百分之五十七,最大薯块重一点零五斤。采用抱窝办法,整薯播种。品种为克新3号。室内催芽,催芽时间比大田提前二十天,待芽长到三至五厘米时,使室温降低到摄氏六度左右,锻炼薯芽适应露地十厘米土层的地温,以便播种。
Last year we carried out spring potatoes per plant high yield cultivation test, a total of 20 test materials, the average single potato weight more than eight pounds, the largest single potato weighing fourteen pounds.
