Abstract

Precision soil fertilization is an important aspect of smart precision agriculture development, and the fertilization prescription map is a prerequisite for precision fertilization. Taking grapevine soil information as an example, this study explores the impact of different sampling densities on the accuracy of soil nutrient distribution. Experimental trials were conducted using sampling densities of 1m x 1m, 3m x 3m, 6m x 6m, 9m x 9m, and 12m x 12m, with the optimal sampling density determined to be 6m x 6m. Nutrient distribution maps were created using Bigemap and ArcGIS software, and based on nutrient balance calculations using ArcGIS software, fertilization prescription maps were developed. Furthermore, precise fertilization schemes for nitrogen, phosphorus, and potassium fertilizers were formulated based on the prescription maps. This study provides methodological and data support for research on precision soil fertilization.

Abstract in Chinese

土壤精准施肥是智慧精准农业发展的重要方面,施肥处方图是精准施肥的前提。本文以葡萄园土壤信息为例,探索了不同采样密度对土壤养分分布准确度的影响,以1m x 1m, 3m x 3m, 6m x 6m, 9m x 9m, and 12m x 12m,为例进行了试验,确定了最佳采样密度为6m x 6m,使用Bigemap和ArcGIS软件绘制了养分分布图,根据养分平衡法运用ArcGIS软件得出相应的施肥处方图,并基于处方图给出了氮、磷、钾三种肥料的精准施肥方案,为土壤精准施肥研究提供了方法支持和数据支持。
