摘要
通过开展田间试验研究不同有机肥替代化肥施肥模式对柑橘品质及土壤性质的影响,通过设置空白不施肥、常规施肥、化肥优化、15%有机替代和30%有机替代5个处理进行对照试验。结果表明,相比空白不施肥及化肥优化,各有机肥替代化肥处理的土壤理化性质和果实品质均有不同程度的提高和改善,其中15%有机替代化肥土壤pH值最高,土壤有机质和碱解氮含量随着有机肥替代比例的上升而增加。15%有机替代处理果汁率最高,可溶性固形物含量较常规施肥降低;同时15%有机替代处理总酸含量最低。从土壤质量提升和柑橘品质改良角度出发,可以采取15%有机肥替代化肥模式。
Field experiments were conducted to study the effects of different organic fertilizer substitution modes on the quality and soil properties of citrus.A control experiment was conducted by setting up five treatments:no fertilization,conventional fertilization,chemical fertilizer optimization,15%organic fertilizer substitution,and 30%organic fertilizer substitution.The results showed that the soil physical and chemical properties and fruit quality of each organic fertilizer substitution treatment were improved to varying degrees compared with the blank non-fertilization and chemical fertilizer optimization.Among them,the soil pH value of 15%organic fertilizer substitution treatment was the highest,and the soil organic matter and alkali-hydrolyzable nitrogen content increased with organic fertilizer substitution ratio.The juice rate of 15%organic fertilizer substitution treatment was the highest,and the content of soluble solids was lower than that of conventional fertilization.At the same time,15%organic fertilizer substitution treatment has the lowest total acid content.From the perspective of soil quality improvement and citrus quality improvement,15%fertilizer organic fertilizer can be used instead of chemical fertilizer.
