Effects of Different Concentrations of Biogas Slurry Fertilization on Growth and Economic Characters of Camellia oleifera
摘要
Abstract
To explore the application of biogas slurry in forest, efficient waste resource recycling, and green ecological management of Camellia oleifera, different diluted concentrations (20%, 40%, 60%, 80%, 100%) of biogas slurry were applied. Plant height, ground diameter, crown, yield and fruit quality index were measured to examine effects of biogas slurry concentrations on C. oleifera growth and fruit economic characters. Positive effects were observed by application of biogas slurry on C. oleifera plant height, ground diameter, crown breadth, yield, and single fruit weight, seed yield, kernel water content. In addition, significant differences among blocks, interac-tions between block and biogas slurry concentration were also observed. With the increase of concentration of biogas slurry dilution, C. oleifera height, ground diameter and dry kernel, seeds yield efficiency, dry seed yield efficiency and fresh fruit yield efficiency are increased. Meanwhile, A-2 reached maximum value. The crown growth was also significantly increased by biogas slurry concentrations, A-4 treatment achieved maximum value. Biogas slurry con-centrations significantly impacted fruit weight, fresh dry out of the seed yield and seed rate. The fresh seed water content decreased and increased with treatment levels. In terms of production, A-2 and A-3 treatments could obtain the maximum value. Using growth and fruit economic indicators for principal component analysis, the results showed that the most advantageous biogas slurry concentration treatment is A-2, followed by A-3. To obtain the best fertili-zation management, application of biogas slurry concentration of 40% could be considered in practice.关键词
