Effects of Applying Biogas Slurry-Based Fertilizer on Pachira macrocarpa
A pot experiment was conducted in this study to compare the effects of applying biogas slurry-based and inorganic compound fertilizer on the physiological indices,character and biomas with equivalent nutrient principles.The result showed that the optimum amount of fertilization on Pachira macrocarpa was 750 kg/hm2 under the condition of this experiment.In this case,the highest increase of chlorophyll content,total leaf area,ground diameter,diameter at breast height(DBH),plant height,fresh weight,dry weight and fresh weight of leaf biomass with applying inorganic compound fertilizer was 13.8%,65.0%,26.2%,44.8%,37.2%,51.7%,114.6%,65.0%.
