摘要:

为探究不同改良措施对雷竹林复耕土壤肥力和作物产量的影响,设置对照(CK)、常规施肥(CF)与综合措施(CM)共3个处理,开展轮作试验。结果显示,土壤理化性质不仅受不同处理的影响,还受作物栽培季节及其交互作用的共同影响。至第三季作物收获时,各处理间的土壤碱解氮、有效磷、速效钾、有机质含量及pH值均无显著差异。CF与CM处理提高了土壤中酸杆菌门和绿弯菌门的相对丰度,同时降低了变形菌门和拟杆菌门的相对丰度。在三季作物中,CF和CM处理均能提高作物产量。本研究为复耕土壤的改良提供了有效途径与理论依据。

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.
