中微量元素肥料“泾谷”对小麦增产效果

Effects of the Secondary and Micro-Nutrient Fertilizer “Jinggu” on Wheat Yield

摘要: 本试验研究中微量元素肥料“泾谷”对小麦生长发育及产量的影响。结果表明，“泾谷”对小麦株高、穗长、有效穗数、穗粒数和千粒重等指标影响程度不同，其中在调控株高、提高千粒重和最终产量方面效果尤为明显。与对照相比，“泾谷”处理小麦产量提高11.92%，亩均增收112.71元，表现出良好的增产增效潜力。研究结果表明，在磷钾养分相对充足条件下，合理补充中微量元素有助于改善养分结构、提高肥料利用效率，具有较高的推广应用价值，可为小麦生产中科学追肥提供参考依据。

Abstract: This study evaluated the effects of the micronutrient fertilizer Jinggu on wheat growth, development, and grain yield. The results showed that Jinggu exerted varying influences on plant height, spike length, effective spike number, grains per spike, and thousand-kernel weight, with particularly pronounced effects on reducing plant height and increasing thousand-kernel weight and final yield. Compared with the control, wheat yield under the Jinggu treatment increased by 11.92%, resulting in an average income increase of 112.71 yuan per mu. The results indicate that under conditions of relatively sufficient soil phosphorus and potassium, appropriate supplementation of micronutrients can improve nutrient balance and fertilizer use efficiency. Therefore, Jinggu shows good potential for yield and economic benefits and provides a scientific basis for rational topdressing management in wheat production.
