1. Project Overview
Targeting large‑scale planting scenarios, this solution builds a lightweight, practical and scalable smart‑farm system with the core principle of "remote pump management, zoned irrigation, precise water‑fertilizer application, and traceable data records". The remote pump‑house controller, single‑channel simple intelligent water‑fertilizer machine and smart irrigation valves are connected to a unified management platform. Administrators can complete daily irrigation and fertilization management via mobile phones or computers.
2. Construction Objectives
‑ Realize remote pump start‑stop, operating‑status viewing and fault alarms to reduce on‑site manual visits. ‑ Implement zoned irrigation according to field plots, corn growth stages and soil moisture conditions to avoid flood irrigation. ‑ Achieve simultaneous water and fertilizer application via the single‑channel water‑fertilizer machine, improving fertilization uniformity and fertilizer utilization efficiency. ‑ Archive irrigation, fertilization and equipment‑operation records to support subsequent planting management and large‑scale expansion.
3. Overall System Architecture
After the management platform issues tasks, the remote pump‑house controller activates the water‑source power supply; smart irrigation valves open by field zones. When top‑dressing fertilization is required, the intelligent water‑fertilizer machine injects fertilizer solution into the main pipeline at preset ratios, realizing coordinated operation of "Pump House — Pipeline Network — Valves — Field Plots".

5. Suggestions on Water‑fertilizer Management for Corn Growth Stages
| Growth Stage | Management Focus | Recommended Operation |
|---|---|---|
| Seedling Stage | Seedling preservation & root promotion; maintain proper soil moisture | Light & frequent irrigation; small‑volume supplementary fertilization subject to seedling conditions. |
| Jointing Stage | Promote stalk and leaf development | Zoned irrigation plus simultaneous water‑fertilizer operations according to top‑dressing plans. |
| Tasseling & Pollination Stage | Guarantee water supply & mitigate impacts of high‑temperature drought | Prioritize irrigation for key plots to avoid water shortage affecting pollination. |
| Grain‑filling Stage | Boost grain plumpness while restraining excessive vegetative‑growth & lodging risk | Supply moderate water subject to soil moisture; control fertilization dosage and timing. |
6. Typical Workflow
‑ Administrators select irrigation zones on the platform and set operation time, irrigation duration and fertilization parameters. ‑ The platform issues commands; the remote pump‑house controller starts pumps and corresponding smart valves open sequentially or simultaneously. ‑ If fertilization is required, the intelligent water‑fertilizer machine injects fertilizer solution into the main irrigation pipeline at preset ratios. ‑ Upon task completion, the system automatically shuts down water‑fertilizer equipment, valves and pumps, and saves execution logs. ‑ Alarms pop up on the platform for power failure, communication breakdown or equipment faults for timely disposal.
7. Agricultural‑ecological Application Benefits
