Solution Details

The Precision Drip Irrigation Intelligent Control System for Cotton & Wheat by Ecolor Technology is a comprehensive solution designed to optimize water and fertilizer use in large-scale agriculture. It integrates real-time soil moisture and weather data with precise control hardware to enable variable-rate irrigation, significantly reducing water waste compared to traditional flood methods.

Addressing Major Agricultural Water Challenges

In Xinjiang, China's largest cotton region with over 35 million mu using sub-film drip irrigation, and the North China Plain with over 150 million mu of wheat adopting modern irrigation, water efficiency is critical. Traditional flood irrigation can waste 400-600 cubic meters per mu.

This intelligent irrigation control system directly tackles this issue, enabling precision application that can reduce water usage to 200-300 cubic meters per mu, conserving a vital resource while maintaining crop health.

Core System Components & Advantages

Intelligent Decision-Making

Uses real-time soil moisture sensors and weather station data as the primary inputs for automated irrigation scheduling.

Precise Water Measurement

Features LGF electromagnetic flowmeters for accurate per-unit water metering, providing reliable data for management and billing.

Variable-Rate Control

Smart field water devices control electromagnetic valves to deliver different amounts of water to specific zones as needed.

Integrated Fertigation and Reliable Communication

The system goes beyond water management with an integrated fertigation platform. This allows for the precise delivery of liquid fertilizers through the irrigation system, synchronizing nutrition with crop demand.

At the heart of data acquisition and control is the robust Hero V9 RTU. Powered by solar energy and equipped with 4G/BeiDou dual-mode communication, it ensures stable operation and remote access even in remote agricultural fields.

Dual Crop Mode Support for Cotton and Wheat

A key feature of this precision irrigation control system is its flexibility to support the dominant irrigation methods for two major crops. It is expertly configured for cotton sub-film drip irrigation, common in Xinjiang.

Simultaneously, the system fully supports center-pivot sprinkler irrigation and subsurface drip irrigation modes increasingly used for wheat cultivation on the North China Plain. This makes it a versatile investment for diverse farming operations.
