摘要

[目的] 研究黄土高原区域油松造林中施用BGB微生物菌剂对油松造林成活率、树高、地径生长的影响

以及土壤养分与水分的变化

为BGB微生物菌剂在黄土丘陵地区的植被恢复应用提供理论依据和技术支持。[方法] 在不同坡面处施用3种量的BGB微生物菌剂

观察不同量的处理对油松及土壤养分的影响。[结果] BGB微生物菌剂能够显著提高苗木的成活率

促进苗木树高、地径的增长;可以显著地提高土壤中各养分的含量

增加土壤含水量

且影响随着土壤深度的增加而减小

随坡度的降低而变大。其中对土壤中速效磷和有机质的影响最显著;BGB微生物菌剂能够明显改善土壤的含水量

并且在土壤20-40 cm处作用较明显。[结论] BGB微生物菌剂对油松造林成活率、生长量与土壤养分有显著的影响。

Abstract

[Objective] We aimed to study the effects of BGB microbial agents on the survival rate of Pinus tabulaeformis afforest

height of tree and growth of ground diamete

and investigate the changes in soil nutrient and water content with the utilization of BGB microbial agents

in order to provide theoretical basis and technical support for vegetation restoration in Loess Plateau.[Methods] We applied three different amounts of BGB microbial agents at different slopes to observe its influence on P. tabulaeformis and soil nutrient.[Results] The BGB microbial agents not only significantly increased the survival rate of plant and promoted the height of tree and the growth of ground diameter

but also dramatically increased soil nutrient content and water content. And this effect decreased as the soil was deeper and the slope was steeper. Moreover

BGB microbial agents influenced soil available phosphorus and organic matters significantly

and improved soil water content dramatically

especially at the depth of 20-40 cm.[Conclusion] BGB microorganism bacterium agent has a significant effect on the survival rate and amount of growth of P. tabulaeformis afforest and soil nutrient.
