摘要

氮肥在当今对产量要求极高的农业中发挥着至关重要的作用。使用包膜肥料是减少施肥次数、降低施肥剂量和限制环境损失风险的一种可能选择。本研究评估了传统硝酸铵钙(CAN)与油基聚合物包膜硝酸铵钙(CAN)(按肥料重量计,厚度为 4 (cCAN4) 或 6% (cCAN6))以 1:1 或 1:2 的混合比例一次性施用对冬小麦和油菜产量和质量的影响。无论是在生长季节(GS)还是在试验地点,冬小麦的平均产量都没有受到所研究肥料的显著影响。相反,与对照组(分次施氮)相比,平均质量参数值较低,这可能是由于早春单一施氮造成的。所研究的处理方法对两个 GS 和两个实验点的油菜籽产量都有显著影响。平均而言,以 1:2 的比例处理 cCAN4 的种子产量最高(2.8 吨/公顷)。与对照(2.2 吨/公顷)相比,显著增加了 24.8%。与冬小麦类似,油菜的质量指标(含油量)在使用包衣 CAN 混合物后也有所降低。在油菜施肥时,一次性施用无涂层和有涂层的混合加气铵是一种有效的替代方法,可替代在植被生长期间重复施用的常用分次氮剂量。

The Effect of Oil-based Polymer Coated CAN Fertilizer on the Yield and Quality of Triticum aestivum L. and Brassica napus L.

The Effect of Oil-based Polymer Coated CAN Fertilizer on the Yield and Quality of Triticum aestivum L. and Brassica napus L.

The fertilization with nitrogen plays a crucial role in today’s agriculture characteristic with a high demand for production. The utilization of coated fertilizers represents a possible option to lower the number of applications, lower the dose and limit the risk of environmental losses. The effect of conventional calcium ammonium nitrate (CAN) applied in a single application in blend (1:1 or 1:2) with oil-based polymer coated CAN in thicknesses of 4 (cCAN4) or 6% (cCAN6) by weight of the fertilizer on the yield and quality of winter wheat and oilseed rape was evaluate. The average yields of winter wheat were not significantly influenced by the examined fertilization in either the growing season (GS) or the experimental site. On the contrary, the qualitative parameters on average resulted in lower values in comparison with the control (split N fertilization), possibly due to the single application of nitrogen in early spring. The examined treatments significantly influenced the seed yield of oilseed rape in both GS and both experimental sites. On average, the highest yield of seed (2.8 t/ha) was observed on treatment cCAN4 in a 1:2 ratio. This represents a significant increase by 24.8% compared to the control (2.2 t/ha). Similarly, to winter wheat, the qualitative parameter of oilseed rape (oil content) was lower after the examined blends with coated CAN. The fertilization of oilseed rape with blends of uncoated and coated CAN applied in the single application is a validate alternative to commonly used split nitrogen doses applied repeatedly during vegetation.

期刊介绍: The Journal of Soil Science and Plant Nutrition is an international, peer reviewed journal devoted to publishing original research findings in the areas of soil science, plant nutrition, agriculture and environmental science. Soil sciences submissions may cover physics, chemistry, biology, microbiology, mineralogy, ecology, pedology, soil classification and amelioration. Plant nutrition and agriculture submissions may include plant production, physiology and metabolism of plants, plant ecology, diversity and sustainability of agricultural systems, organic and inorganic fertilization in relation to their impact on yields, quality of plants and ecological systems, and agroecosystems studies. Submissions covering soil degradation, environmental pollution, nature conservation, and environmental protection are also welcome. The journal considers for publication original research articles, technical notes, short communication, and reviews (both voluntary and by invitation), and letters to the editor.
