新疆是全国滴灌应用面积最大的地区，水肥一体化技术已成为新疆农业重大支持技术之一。变量施肥技术是根据土壤养分的空间变异，经决策生成变量施肥处方图进行施肥的一种技术，通常多应用于基肥撒施环节。目前新疆轮灌区划分区域大，现有水肥管理系统难以适应基于处方图的变量施肥需要。本课题提出一种基于边缘计算和分布式智能控制的滴灌变量施肥技术，实现土对大田施肥系统中施肥处方图的快速获取、施肥量、施肥时间的精准控制以及分布的施肥装置安全正常运行，从而更加充分的发挥滴灌水肥一体化的优势。.主要研究内容包括（1）研究适合滴灌小区与处方图相匹配的分区方法，以适应滴灌变量施肥需求。（2）基于边缘计算的滴灌施肥分布式控制模型研究（3）试验验证并进行参数优化；本研究不仅能够节约劳动力，进一步提高滴灌施肥过程中的水肥利用效率，达到减少投入，提高作物产量、品质和保护环境的作用，促进新疆生产建设兵团精准农业的发展。

Xinjiang is the largest area of drip irrigation in China, and the integrated technology of water and fertilizer has become one of the major supporting technologies for agriculture in Xinjiang. Variable-rate fertilization is a technique of fertilization based on spatial variation of soil nutrients, which generates variable-rate fertilization prescription map by decision-making. It is usually used in base fertilizer spraying. At present, Xinjiang rotation irrigation area is divided into large areas, and the existing water and fertilizer management system is difficult to meet the need of variable rate fertilization based on prescription map. In this project, a variable rate fertilization technology for drip irrigation based on edge calculation and distributed intelligent control is proposed. It can realize the rapid acquisition of fertilization prescription map, precise control of fertilization amount, fertilization time and safe normal operation of distributed fertilization device in soil-to-field fertilization system, so as to give full play to the advantages of integration of drip irrigation, water and fertilizer..The main research contents include: (1) To meet the demand of variable rate fertilization for drip irrigation, the zoning method suitable for drip irrigation plots and prescription maps is studied. (2) Distributed control model of drip irrigation fertilization based on edge computing (3) Experimental verification and parameter optimization. This study can save labor, further improve the efficiency of water and fertilizer use in the process of drip irrigation fertilization, reduce input, improve crop yield, quality and protect the environment, and promote the development of precision agriculture in Xinjiang Production and Construction Corps.
