margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;"> 切块:切块时间在播种前1个月进行,切块前捡出烂薯、病薯等不宜作种子的薯块。切刀用酒精消毒,50克左右小薯一刀纵破,75~100克大薯可切4块,但每块至少有中、上部的一个健壮芽,刀紧贴主芽一侧切,一般每千克切50块。切块太小,苗子弱小,太大造成种子浪费成本高。种薯切块后晾晒1~2天,使刀口愈合,然后进行催芽。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;"> 催芽:在向阳的地方,建个塑料小拱棚,将切好晾晒的薯块一层薯块一层土,可放5层,最上层盖5厘米厚的土,把棚膜压严,晚上盖好保温物,如草席、麦秸等,芽长达到2~3厘米最好,种植前几天扒出炼芽,芽以见光发绿最好。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;"> 适时播种:当10厘米地温稳定在7℃时即可播种。棉薯套种地膜覆盖2月底3月初播种,播种时按芽大小将薯块分开播种,有利于同行同时放苗。按种植模式在垄上开沟,沟深10~12厘米,覆土8~10厘米。盖地膜前,在垄上喷施除草剂拉索,可有效抑制杂草。</span></p><p style="max-inline-size: 100%;
