摘要(Abstract)：

沙地因缺水少肥导致牧草存活率底，生长缓慢。高吸水性竹纤维结合枯草芽孢杆菌对沙化地植被的恢复效果，结果如下：（1）与对照组相比试验组月均土壤湿度高38.06%，月均土温低2.89%,0～10cm处土层细菌、真菌数量比对照组高126.69%和50.25%,(2)试验组牧草全氮、全磷、全钾和产量比对照组增加114.49%、35.74%、44.47%和75.76%，试验组土壤铵态氮、有效磷、速效钾、有机质均高于对照组，但不显著；（3）试验组披碱草存活显著高于对照组，单位面积内植株数量超过对照组345.04%，结果表明高吸水性竹纤维结合枯草芽孢杆菌够有效的提升沙地土壤水分、养分含量，提高沙地上植株存活率。
Due to lack of water and fertilizer in sandy land, the grass survival rate is low and the growth is slow. In this paper, the effect of super absorbent bamboo fiber combined with Bacillus subtilis on vegetation restoration of sandy land was explored. The results were as follows:(1) Compared with the control group, the average monthly soil humidity in the experimental group was 38.06% higher, and the average monthly soil temperature was 2.89% lower. The number of bacteria and fungi in the 0-10cm soil layer was 126.69% and 50.25% higher than that in the control group;(2) The total nitrogen, total phosphorus, total potassium and yield of forage in the experimental group increased by 114.49%,35.74%, 44.47% and 52.63% compared with the control group. The soil ammonium nitrogen, available phosphorus,available potassium and organic matter in the experimental group were higher than those in the control group, but not significantly;(3) The survival rate of Elymus dahuricus in the experimental group was significantly higher than that in the control group, and the number of plants per unit area was 345.04% higher than that in the control group. The results showed that the super absorbent bamboo fiber combined with Bacillus subtilis could effectively improve the soil moisture and nutrient content in sandy land, and improve the plant survival rate in sandy land.
