摘　　要：近年来互助县在干旱山区大力推广全膜覆盖马铃薯栽培技术,取得了显著的经济效益和社会效益,但全膜覆盖栽培马铃薯中的施肥问题研究过少,本文依据"化肥减量增效"和"耕地质量保护"就全膜覆盖栽培马铃薯施肥问题进行方差分析和肥料利用率研究,力求扭转"土壤养分过量积累"和"养分损失"严重等问题。In recent years the Huzhu county in arid mountainous area of whole promoting the potato cultivation techniques,has obtained the remarkable economic and social benefits,but the whole film covering cultivation of potato fertilization studies,too little,in this paper,based on"reducing fertilizer efficiency"and"the cultivated land quality protection"whole film covering cultivation potato fertilization problems on research,analysis of variance and fertilizer utilization to reverse"excessive soil nutrient accumulation"and"nutrient loss"serious problems.
