马铃薯增产六法

   去尾芽 经试验观察证明马铃薯的尾芽成株后,产量仅是顶芽或侧芽成株苗的1/3,为此在切种薯时应对尾芽弃置不用。
  高垄栽培 高垄栽培两边培土,能增加活土层根茎部位土壤疏松,提高地温,满足早期根茎发育所需温度。
  去花蕾 马铃薯可利用的部分是地下的块茎,它根本不需要开花授粉获得。要想获得高产,必须见蕾就要掐去,以节省养分促进块茎的生长。
  少铲多直趟 马铃薯能结块茎的肉质根在土壤里水平生长,往往由于深铲切断了肉质延生根,人为造成减产,所以铲完头遍后只趟不铲,能有效地提高产量。
  补镁促产 专家研究证明,在马铃薯的生长过程中,尤其是薯块膨大期,如镁肥充足,不仅产量高,而且淀粉积累多,品质好,因此在植株45厘米高时,每株要以50~100克硫酸镁对水溶化后追入。
  叶面喷肥 在施足底肥的情况下,从展叶起,每10天叶喷一次0.1%的硫酸镁、0.3%的磷酸二氢钾、1000倍的三十烷醇混合液,连喷3~5次,能显著提高产量。
