滴灌施用相变液配方肥对青菜产量和品质的影响
Effects of drip-fertigation with aerobic bio-digestion liquid fertilizer on yield and quality of pakchoi
摘要
Abstract
To achieve the objectives of harmless treatment,reduction,and resource utilization of food waste,this study used kitchen waste as raw material,which was processed through phase-change treatment integrated with enzymatic hydrolysis and microbial fermentation.The resulting liquid product was formulated into an aerobic bio-digestion liquid fertilizer by supplementing macronutrients and humic acid.The effect of this fertilizer on crop yield and quality was investigated using integrated drip-fertigation technology.The experiment was conducted with pakchoi as the test crop,with drip irrigation using clear water set as the control,and treatments including aerobic bio-digestion liquid fertilizer and conventional fertilization.The results showed that drip-fertigation with aerobic bio-digestion liquid fertilizer effectively promoted the growth of pakchoi,increased yield,and improved agronomic traits such as plant height and fresh weight per plant.Under this treatment,nitrate content was significantly reduced at the Yangdu experimental site,while no significant effect was observed at the Tonglu experimental site,and there was no significant influence on crude fiber content.In conclusion,drip application of aerobic bio-digestion liquid fertilizer demonstrated favorable ecological and economic benefits in pakchoi production.关键词
