滨海沙地马铃薯种植和高产研究

Study on the Cultivation and High Yield of Potatoes in Coastal Sandy Soil

滨海沙地土壤贫瘠，种植马铃薯采用高Ｋ处理，产量达３．８２５ｋｇ／ｍ２．产量的高低与Ｎｉ、Ｚｎ、Ｋ、Ｍｎ含量密切相关．在６～７叶期追肥有利于大中块茎的形成．福建滨海风沙地资源丰富，在此类沙地种植马铃薯是扩大生产的一条新途径．

The potato treated with high K had hightest quanlity and yield (3 825kg/m 2).The yield of potato was driectly related to the content of N,Zn,K,Mn,elenents in the soil.Applying fertilizer at 6～7 leaves stage was heneficial to form of big or medium tubers.The meteorological factories of coastal zone in Fujian province of China is fit to culture of potatoes.
