摘要:

研究不同增效型的DAP肥料在新疆土壤中的生态适应性,旨在筛选出对新疆玉米生长具有促进作用且低养分的新型DAP肥料,为新疆玉米DAP肥料的选择与施用提供参考,同时为新疆地区低养分高利用率肥料的前沿研究奠定基础。以64% DAP无助剂高养分肥料为对照,将其与低养分肥料57% DAP助剂方案A、57% DAP助剂方案B、57% DAP助剂方案C、57% DAP助剂方案D、57% DAP助剂方案E、57% DAP助剂方案F对比。通过测定不同处理玉米生长形态、生理指标和生物量,并运用回归分析等统计方法评价测定指标。结果显示,增效助剂的添加能够促进玉米植株根部发育,提高玉米叶绿素含量、株高等生理指标。增加助剂的低养分DAP对玉米生长的促进效果有优于高养分DAP肥料的趋势,不同助剂方案对玉米的影响效果不同,其中57% DAP助剂方案A、57% DAP助剂方案E、57% DAP助剂方案F对玉米的促进效果。

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.
