[目的]本项目希望通过在大树移植中应用吊袋输液技术,寻找能提高大树移植成活率的营养液。[方法]在大树移植中应用吊袋输液技术,与传统大树移植技术比较,观察不同浓度的吲哚丁酸、α-萘乙酸钠组合对火力楠的新芽萌发数、枝条生长量以及移植成活率的影响情况。[结果]试验结果表明:当吲哚丁酸浓度为2.0mg/L、α-萘乙酸钠浓度为1.0mg/L时,新芽的萌发量达到最大;而枝条生长量在吲哚丁酸浓度为4.0mg/L、α-萘乙酸钠浓度为1.0mg/L时达到最大。且以上这两个浓度组合的移植成活率均可达到100%。[结论]吲哚丁酸和α-萘乙酸钠组合使用对移植大树的树势恢复生长效果显著,比单一激素使用效果较好。当吲哚丁酸浓度为2.0mg/L,α-萘乙酸钠浓度为1.0mg/L;吲哚丁酸浓度为4.0mg/L,α-萘乙酸钠浓度为1.0mg/L时对移植树木的树势恢复生长能起到良好的促进效果。
[Objective] The project hopes to find a nutrient solution that can improve the survival rate of large tree transplantation by applying the sachet infusion technology in large tree transplantation. [Method] In the transplantation of big tree, the bagging infusion technique was used to compare the germination number, branch growth and transplantation of Pyrenia naevensis with different concentrations of indole butyric acid and α-naphthalene sodium acetate. The impact of survival rate. [Result] The results showed that when the concentration of indole butyric acid was 2.0 mg / L and the concentration of α-sodium naphthaleneacetate was 1.0 mg / L, the germination of new shoots reached the maximum; while the growth of shoots was observed when the concentration of indole butyric acid was 4.0mg / L, sodium alpha-naphthalene acetate concentration reached 1.0mg / L maximum. And the combination of these two concentrations of graft survival rate can reach 100%. [Conclusion] The combination of indole butyric acid and α-naphthalene sodium acetate has significant effect on the recovery of tree vigor of transplanted large tree, which is better than that of single hormone. When the concentration of indole butyric acid was 2.0 mg / L, the concentration of α-sodium naphthaleneacetate was 1.0 mg / L, the concentration of indole butyric acid was 4.0 mg / L and the concentration of α-sodium naphthaleneacetate was 1.0 mg / L, The restoration of tree vigor can play a good promotion effect.
