In November 2023, the nation’s first smart glass greenhouse equipped with a negative-pressure sterilization system, built by Ruixue Global for the National Biological Breeding Industry Innovation Center, was officially put into operation.

This project is a high-throughput phenotypic characterization system smart greenhouse, divided into three functional zones to meet scientific research needs: the Plant Pathology Phenotypic Characterization Zone, the Accelerated Breeding and Precision Phenotypic Cultivation Zone, and the Equipment Operation Zone. It is the first smart glass greenhouse in China to incorporate a negative-pressure environment and sterilization system. The cultivation zone focuses on accelerated crop breeding and precise phenotypic characterization of plants.

Negative-Pressure Greenhouse

This project innovatively employs a negative-pressure sterilization system, marking the first application of such technology in a Chinese smart glass greenhouse. The integration of negative-pressure environments and high-intensity UV sterilization systems prevents experimental cross-contamination and eliminates the risk of pathogen leakage during plant disease resistance research.

Independently Controlled Isolation Compartments

The greenhouse features 27 isolated compartments in the cultivation and pathology zones. Each compartment allows independent control of temperature, lighting, water, and nutrient conditions. Separated corridors and independent buffer rooms enable simultaneous execution of diverse plant pathology experiments.

Dual Redundancy Heating Systems

The greenhouse utilizes two heating systems:

1. 1. Tichelman principle-based isothermal heating system for uniform temperature distribution.

2. 2. ground-source heat pump combined with fan coil units for heating and cooling.
   This dual-redundancy design ensures uninterrupted operation of germplasm resource experiments.

In this era of challenges and opportunities, the completion of this high-throughput phenotypic characterization smart greenhouse provides robust hardware and software support for the National Biological Breeding Industry Innovation Center. Its innovative design and advanced infrastructure enable precise environmental control, diverse cultivation conditions, and accelerated crop breeding. This breakthrough facility injects new vitality into plant phenotypic research, addresses "bottleneck" challenges in breeding, and propels future scientific endeavors onto a fast track.
