生物有机肥对工程扰动土地玉米的光合特性及产量的影响——以乌蒙山区云南省曲靖市马龙县试验地为例
Effects of Bio-organic Fertilizer on Photosynthetic Characteristics and Yield of Maize in Engineering Disturbed Land——A Case of Malong County Experiment Land in Qujing City, Yunnan Province, Wumeng Mountainous Area
摘要
Abstract
[Objective] To research the effects of bio-organic fertilizer on photosynthetic characteristics and yield of maize in engineering disturbed land.[Method] With one-year engineering disturbed land and maize as the research objects and materials,we researched the effects of different fertilization treatments on the photosynthetic characteristics and yield of maize.[Result] Compared with the non-fertilizer treatment,the maize yield of bio-organic fertilizer was obviously improved.Intercellular CO2 concentration also enhanced.Except the treatment of cow dung and bacteria agent a,maize yield in treatment of applying bio-organic fertilizer enhanced significantly.And the treatment of cow dung and bacteria agent b was the most significant.Compared with single application of fertilizer,treatment of cow dung and bacteria agent b reached the maximum values in maize yield,photosynthetic rate,stomatal conductance,intercellular CO2 concentration and transpiration rate.Except intercellular CO2 concentration,treatment of cow dung and bacteria agent b reached significant differences in maize photosynthetic rate,stomatal conductance and transpiration rate compared with single application of fertilizer.Bacteria agent b was superior to bacteria agent a in enhancing maize photosynthetic rate and intercellular CO2 concentration,and cow dung was superior to refined organic fertilizer.In bio-organic fertilizer treatment,cow dung was superior to refined organic fertilizer in affecting the maize transpiration rate.[Conclusion] This research provided scientific basis and practice guidance for rational fertilizer application,rapid fertilization of engineering disturbed land,and enhancing crop quality.关键词
