Abstract

Abstract:

To investigate the effects of different improvement measures on soil fertility and crop yield in reclaimed Lei bamboo forest, a rotation experiment was conducted with three treatments: control (CK), conventional fertilization (CF), and comprehensive measures (CM). Results showed that soil physicochemical properties were influenced not only by the different treatments but also by the crop season and their interactions. By the harvest of the third crop season, no significant differences were observed among the treatments in terms of soil alkali-hydrolyzable nitrogen, available phosphorus, available potassium, organic matter content and pH value. Both CF and CM treatments increased the relative abundance of Acidobacteria and Chloroflexi while reducing the relative abundance of Proteobacteria and Bacteroidetes. Over the three crop seasons, both CF and CM treatments enhanced crop yield. This study provides effective strategies and a theoretical basis for improving reclaimed farmland.

Key words: soil improvement, crop rotation, Lei bamboo forest, reclaimed farmland, biochar
