The objective of this study was to compare the growth using an organic fertilizer culture comprising wheat straw, mushroom residue or sawdust and dry dung, or plant growth-promoting microbes (PGPM) on the growth conditions and nutritional status of Elymus dahuricus to provide a set of feasible plans for the treatment and restoration of abandoned land exhibiting lower organic matter, calcification, and alkaline soil of the Qilianshan coal mine. Pot experiments were conducted on four groups to study the effect of the characteristics of nutrient absorption of E. dahuricus : (1) original soil with or without the addition of soil bacteria and compound bacteria (nitrobacteria and Pleurotus ), (2) different ratios of original soil mixed with different proportions of organic fertilizer, (3) different proportions of original soil mixed with different proportions of organic fertilizer and soil bacteria, and (4) different proportions of original soil mixed with different proportions of organic fertilizer and compound bacteria. Results showed that original soil supplemented with different PGPM, organic fertilizer treatment, and the organic fertilizer combined with different PGPMs was an obvious increase in the growth of E. dahuricus . In particular, 40% of organic fertilizers mixed with the compound bacteria (nitrobacteria and lateral bacteria) exhibited the best growth trend, significantly improving the soil nutrients, the growth of E. dahuricus , and the nutritional status, and providing a reliable scientific foundation for the treatment and restoration of the abandoned land of the Qilianshan coal mine.

微生物与有机肥配合使用对极乐草的影响

这项研究的目的是比较使用有机肥料培养物（包括小麦秸秆，蘑菇残留物或木屑和干粪）或植物促生微生物（PGPM）的生长情况，以研究野豌豆的生长条件和营养状况，从而提供一套祁连山煤矿有机质低，钙化和碱土含量低的废弃土地的处理和恢复的可行性计划 对四组进行了盆栽试验，以研究水hur的养分吸收特性的影响：（1）添加或不添加土壤细菌和复合细菌（硝化细菌和侧耳属）的原始土壤，（2）不同比例的原始土壤中掺有不同比例的有机肥，（3）不同比例的原始土壤中混有不同比例的有机肥和土壤细菌，（4）不同比例的原始土壤中混有不同比例的有机肥和复合细菌。结果表明，不同PGPM，有机肥处理，有机肥与不同PGPMs配合使用的原始土壤，对E. dahuricus的生长有明显的促进作用。特别是40％的有机肥料与复合细菌（硝化细菌和侧生细菌）混合，表现出最佳的生长趋势，显着改善了土壤养分，黄E的生长以及营养状况，并为有机肥料提供了可靠的科学依据。祁连山煤矿废弃土地的处理与恢复。
