Abstract:

This study investigated the ecological adaptability of different efficiency-enhanced DAP fertilizers in soil of Xinjiang, aiming to identify novel DAP fertilizers with lower nutrient content that promote the growth of maize in Xinjiang. The research provided a reference for the selection and application of DAP fertilizers for maize in Xinjiang, while also offered a basis for cutting-edge research on low-nutrient, high-efficiency fertilizers in the region. Using 64% DAP without additives (high-nutrient fertilizer) as the control, comparisons were made with low-nutrient fertilizers, including 57% DAP with additive (formula A), 57% DAP with additive (formula B), 57% DAP with additive (formula C), 57% DAP with additive (formula D), 57% DAP with additive (formula E), and 57% DAP with additive (formula F). The growth morphology, physiological indicators and biomass of maize under different treatments were measured, and statistical methods such as regression analysis were applied to evaluate the results. The results showed that the addition of efficiency-enhancing additives promoted root development in maize plants and improved physiological indicators such as chlorophyll content and plant height. Low-nutrient DAP fertilizers with additives showed a tendency to outperform high-nutrient DAP fertilizers in promoting maize growth. The effects varied among different additive formulations, with formula A, formula E, and formula F demonstrating the most significant promotion effects on maize growth.
