摘　　要：在风积沙地采用沙棘、波斯菊、紫花苜蓿和披碱草构建人工植被固沙,选取滴灌型肥、大量元素肥和尿素3种肥料,每种肥料设置3个浓度梯度进行施肥实验,以确定最适肥料种类及浓度。通过株高和干物质增加量可以看出,施加浓度为1.25‰的滴灌型肥植物株高增加最多,植物干物质量增幅最大,可确定进行风积沙地施肥时优先选择滴灌型肥料。Seabuckthorn,cosmos,alfalfa and Elymus dahuricus were selected to construct artificial vegetation in aeolian sandy land for sand fixation.Drip irrigation fertilizer,large amount of element fertilizer and urea were selected,each fertilizer set 3 different concentrations for determining the optimal fertilizer type and concentration.According to the increase of plant height and dry matter,it can be seen that the increase of plant height is the highest and the increase of plant dry matter quality is the largest when the concentration of drip irrigation fertilizer is 1.25‰,which means the drip fertilizer should be given priority option when applying fertilizers in eolian sandy land.
