通过抗旱造林粉在民勤干旱沙区沙丘“双眉式”麦草方格沙障和丘间低地上分别进行梭梭、沙拐枣裸根苗浸根法应用试验,结果表明:应用抗旱造林粉在民勤干旱沙区造林能够稳定提高造林成活率,也可以提高植物体自身抗性,控制水分丧失,维持植物体水分平衡,延缓植物生命周期,抑制林木生长状态,延长生长期,降低造林成本,促进梭梭、沙拐枣等苗木生长发育。抗旱造林粉是干旱、半干旱沙区提高造林成活率、降低造林成本的一条有效途径。
Through drought-resistant forestation powder in the sand dune “double eyebrow ” wheat straw grid barriers and mound lowland in Minqin arid sandy area, respectively, Haloxylon ammodendron bare root seedling soaking root application test results show that: the application of drought afforestation The planting of silt in Minqin arid sandy area can increase the afforestation survival rate steadily, improve plant self-resistance, control water loss, maintain plant water balance, delay plant life cycle, restrain tree growth, prolong growth period and reduce afforestation Cost, promote Haloxylon, Calligonum and other seedlings growth and development. Drought-resistant forestation powder is an effective way to increase the survival rate of afforestation and reduce the cost of afforestation in arid and semi-arid sandy areas.
