Two greenhouse experiments were focused on the application of arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) in planting of high-biomass crops on reclaimed spoil banks. In the first experiment, we tested the effects of different organic amendments on growth of alfalfa and on the introduced microorganisms. While growth of plants was supported in substrate with compost amendment, mycorrhizal colonization was suppressed. Lignocellulose papermill waste had no negative effects on AMF, but did not positively affect growth of plants. The mixture of these two amendments was found to be optimal in both respects, plant growth and mycorrhizal development. Decreasing doses of this mixture amendment were used in the second experiment, where the effects of microbial inoculation (assumed to compensate for reduced doses of organic matter) on growth of two high-biomass crops, hemp and reed canarygrass, were studied. Plant growth response to microbial inoculation was either positive or negative, depending on the dose of the applied amendment and plant species.
两项温室试验聚焦于丛枝菌根真菌（AMF）和促植物生长根际细菌（PGPR）在复垦弃土堆上种植高生物量作物中的应用。在第一个试验中，我们测试了不同有机改良剂对苜蓿生长以及引入微生物的影响。虽然添加堆肥的基质能促进植物生长，但菌根定殖受到抑制。木质纤维素造纸厂废料对AMF没有负面影响，但对植物生长没有积极影响。发现这两种改良剂的混合物在植物生长和菌根发育两方面都是最优的。在第二个试验中使用了剂量递减的这种混合改良剂，研究了微生物接种（假定用于补偿减少的有机物质剂量）对两种高生物量作物大麻和芦苇状金丝雀草生长的影响。植物对微生物接种的生长反应取决于所施用改良剂的剂量和植物种类，可能是积极的，也可能是消极的。
