| 摘要 | [Objectives] To investigate the performance of different efficiency-enhanced Diammonium phosphate (DAP) fertilizers in Xinjiang soils and identify new low-nutrient DAP formulations that promote maize growth in the region. [Methods] Using 64% DAP (additive-free high-nutrient fertilizer) as the control, it compared with low-nutrient fertilizers: 57% DAP additive Formula A, 57% DAP additive Formula B, 57% DAP additive Formula C, 57% DAP additive Formula D, 57% DAP additive Formula E, and 57% DAP additive Formula F. By measuring maize growth morphology, physiological indicators, and biomass under different treatments, the measured parameters were evaluated using statistical methods such as regression analysis. [Results] The addition of enhancing additives can promote root development in maize plants and increase physiological indicators such as chlorophyll content and plant height. Low-nutrient DAP with additives shows a trend of being superior to high-nutrient DAP fertilizers in promoting maize growth. Different additive formulas exert varying effects on maize, with 57% DAP additive Formula A, 57% DAP additive Formula E, and 57% DAP additive Formula F demonstrating positive effects on maize promotion. [Conclusions] This study provides practical guidance for DAP selection and application in Xinjiang maize cultivation while establishing a foundation for cutting-edge research on high-utilization, low-nutrient fertilizers in arid regions. |
