摘　　要：以神府—东胜煤矿采煤沉陷区为试验地,通过正交试验,分析了覆盖材料、保水剂施用量、肥料配比的保水效果及对成活率的影响。结果表明,覆盖材料、保水剂施用量、肥料配比对长梗扁桃成活率、土壤含水量的影响极显著,其影响程度为:覆盖材料>保水剂施用量>肥料配比。在地膜覆盖—保水剂(60g)—当地土∶肥料(4∶1)的保水措施下,土壤含水量最高达到17.11%,长柄扁桃成活率最高,为80.5%。无任何保水措施的处理土壤含水量为8.59%,成活率仅为30.13%。栽植长柄扁桃的多因素保水技术措施最佳组合为:地膜覆盖—保水剂60g—当地土∶肥料(4∶1)。Selecting the subsidence area of Shenfu—Dongsheng Mining area as the experimental samples,using the orthogonal test,the authors analyzed the effect of water content and survival rate of covering materials,water-retaining agent application amount and fertilizer ratio were analyzed.The results showed that：the influences of covering materials,water-retaining agent application amount and fertilizer ratio on survival rate and soil moisture content of Amygdalus pedunculata Pall.were significant different,and the order of influence degree was：covering materialwater-retaining agent application amountfertilizer ratio.Under water retention measures which including plastic film mulching,water-retaining agent（60g）,ration of local soil and fertilizer（4∶1）,soil moisture content was up to 17.11%,and A.Pedunculata Pall.reached the highest survival rate of 80.5%.Soil moisture content of no water measures was 8.59%,and survival rate was just only 30.13%.The best water retention technique measures combination for A.Pedunculata Pall.was：plastic film mulching with water-retaining agent（60g）and fertilizer ratio（4∶1）.
