通过试验证明;火炬树(Rhus typhina)在太行山区的阳坡,干旱土层薄的土壤上具有强大的抗旱能力。它比油松(Pinus tabulaeformis)成活率提高62.0％,比侧柏(Biota Qrientalis)刺槐(Robinia pseudoacacia)也提高56.0％,而比臭椿(Ailanthus altissima)也提高了20.％。在中厚土壤上通过方差分析,火炬树与臭椿和刺槐之间差异不显著,而与北京杨(Populus Peking)的差异显著。在土层厚的土壤上刺槐则此火炬树成活率提高33.3％。
It is proved through experiments that Rhus typhina has strong drought resistance in the sunny slope of Taihang Mountain and in the thin soil of arid soil. It was 62.0% higher than that of Pinus tabulaeformis, 56.0% more than that of Biota Qrientalis Robinia pseudoacacia, and 20% more than that of Ailanthus altissima. There was no significant difference between Rhus typhina and Ailanthus altissima and Robinia pseudoacacia in the medium and thick soil, but significant difference with Populus Peking. Robinia pseudoacacia on soil thick soil increased the survival rate of this Rhus typhina 33.3%.
