摘要
Abstract
Aiming at the issue of soil acidification in single-cropping rice fields along the river,a field positioning experiment was conducted to investigate the effects of four soil amendments,namely biochar,acidic soil conditioner,lime,and fused calcium-magnesium phosphate fertilizer,on rice yield and soil physicochemical properties.The results showed that all four soil amendments could increase soil pH,reduce soil bulk density,enhance soil porosity,and improve rice yield and nutrient uptake.Compared with the control treatment without any soil amendment,the soil pH under the lime treatment increased by 0.46.The biochar treatment showed a relatively large increase in rice grain yield(by 12.84%)and the comprehensive soil fertility index(by 7.09%).The treatment of fused calcium-magnesium phosphate fertilizer reduced soil bulk density by 10.34%and increased soil total porosity by 5.06%,demonstrating the best effect on improving soil structure.The comprehensive soil fertility index among different treatments followed the order of biochar>lime>soil conditioner=fused calcium-magnesium phosphate fertilizer>no soil amendment.Overall,the improvement effects of soil amendments on soil were closely related to their types.Appropriate amendments should be selected according to the local farmland quality improvement goals.关键词
