Abstract
We studied on the effects of slurry composting and biofiltration liquid fertilizer (SCBLF) on growth of two-year-old poplar clones planted in a reclaimed land mounding soil. The soil on the experimental site had lower concentrations of both exchangeable cations and salinity than before reclamation. However, the content of organic matter was low compared with the most soils. We applied SCBLF to the poplars six times and 5 L in each time for 80 days. Ten clones of six poplar species or hybrids were tested in this study: Populus alba P. glandulosa(Clivus, 72-30, 72-31, Bongwha1), P. deltoides P. nigra(Dorskamp), P. deltoides(Lux) P. deltoides(Harvard)(97-19), P. euramericana(Eco28, I-476), P. nigra P. maximowiczii(62-2) and P. Koreana P. nigra var. italica(Suwon). Growth performance varied more among clones than among species. Average height growth of treated plots was 18% greater than control, and clones Clivus, 97-19, Eco28 and Dorskamp were more vigorous than other clones. Diameter at breast height in treated plots was 41% greater than control, and 97-19, Dorskamp, Eco28 and Clivus were the four best clones in this respect. Mean leaf area of treated trees was 26% greater for control trees. Chlorophyll content was similar between treated and controlled trees. Total nitrogen values in leaves were much higher in treated trees 18%. SCBLF treatment on poplars planted in reclaimed land helped tree growth.
