The purpose of this study was to investigate the influence of soil mixture (1:1, coal mine tailings:forest soil), fertilizer, and Glomus etunicatum inoculation on growth of Albizzia julibrissin DURAZZ.
The coal mine tailings and general forest soil mixture was 50%. The processing and monthly fertilizing of the forest and the solid compound fertilizer dilution was 10% concentration in water, For 8 months, the mycorrhizal was inoculated with Glomus etunicatum spores by inoculating the potted Albizzia julibrissin DURAZZ seeds were investigated.
In the 50% coal mine tailing soil mixture, the plank grew five times more than the mixture with forest soil and coal mine tailings because of trace elements in the coal mine tailings. Also, in the amended soil fertilization content, the dry weight biomass increased three times higher than the coal mine tailings. However, the coal mine tailings doesn''t affect the dry weight of the root nodule and the water potential.
The experiment group''s fertilization height is 1.4 times higher than the control group, correspondingly the aboveground and underground dry weight, R / S ratio, and light saturation point increased. It was six times higher than in the control root nodule dry weight which appears to be closely related to nodulation and nutrients.
The light saturation point, water potential, and nodulation capacity increased in the Arbuscular mycorrhizal Glomus etunicatum vaccinated seedlings of the Albizzia julibrissin DURAZZ. The height was 2.3 time higher in plants with fungus in the forest soil. However, the plants without fungus in forest soils with coal mine tailings, the effect of mycorrhizal inoculation in the soil increased by 1.5 times.
Also, the inoculation of the Albizzia julibrissin DURAZZ leaf nitrogen content in the Arbuscular Mycorrhizal Glomus etunicatum did not change. The phosphorus and zinc content doubled.
When processing coal mine tailings in Arbuscular mycorhizal and Fertilization in combination with the soil, the Albizzia julibrissin DURAZZ grew by 40%, photosynthesis increased by 11%. In forest soils, the height grew by 75% and photosynthesis increased by 9%.
In conclusion, the Albizzia julibrissin DURAZZ seedlings in the treated coal mine tailings growth was inhibited compared to forest soils. However, after the 50-50 mixture of forest soils and coal mine tailings, fertilization amendamentand soil addition by Mycorrhizal inoculation, the seedling growth increased.
