堆肥替代部分化肥对节水抗旱稻品质的影响
The Effects of Compost Replacing Part of Chemical Fertilizer on the Quality of Water-saving and Drought-resistant Rice
摘要
Abstract
Using the water-saving and drought-resistance rice variety"Wanhanliangyou 25"from the Anhui Academy of Agricultural Sciences as experimental material,the effects of copost replacing part of chemical fertilizer on rice physiological traits,soil microbial communities,soil metabolites,and grain quality were investigated through field partition trials.The results showed that the A3 treatment significantly improved rice quality,with the lowest protein content(12.73%),moderate amylose content(24.39%),and reduced total starch content(71.18%),enhancing the softness and palatability of cooked rice.Additionally,under the A3 treatment,the soil microbial community was dominated by nitrogen-fixing bacteria(Rhizobiales)and Bacillus(Bacillales),which promoted nitrogen utilization and plant growth.The slower decline in chlorophyll delayed leaf senescence,while the increased stem base width improved the lodging resistance of water-saving and drought-resist-ance rice.Metabolite analysis revealed that the A3 treatment significantly regulated amino acid,fatty acid,and carbohydrate metabolic path-ways,further validating its quality improvement effects.This study confirms that precise substitution of chemical fertilizers with compost can simultaneously achieve water-saving,drought-resistant,and high-quality goals,providing theoretical and technical support for rice cultivation in water-scarce regions.关键词
