China: Yunnan greenhouses double number of top-grade roses

Anning Northward Flower Industry, a subsidiary of Yunnan Jinyuan Flower Industry, has been planting roses in an energy-saving and low-carbon way in recent years. The company has introduced smart flower greenhouse systems, changing traditional planting methods to create a modern and industrialized demonstration base integrating exhibitions, research and development, production of fresh-cut flowers, and post-harvest processing.

Different planting methods
There is a difference between traditional ways of cultivating roses and the way the flowers are grown in the Yunnan greenhouses. Here, they use an automated fertilizer and water irrigation system. Through AI, the system automatically irrigates and fertilizes the flowers, distributes fertilizer, and monitors and adjusts environmental conditions such as temperature, light, water, humidity, and air. All the water and fertilizer are optimally used so as to be as sustainable as possible. In the same vein, pests in the greenhouses are fought with biological solutions, so no pesticides are used.

Flower quality improvement
It is worth noting that about 30% to 40% of roses grown by traditional farmers are top-grade flowers. In the smart greenhouses, however, this rate can be increased to up to 60%. Because of that, the annual output has increased from 900 thousand flowers per hectare to 2.25 to 2.4 million.

The company has launched a project to 'upgrade' the flower planting garden in 2020, and the construction of the project is progressing in an orderly manner. When the greenhouse is completed, it will be the largest single flower greenhouse in Asia, covering an area of ‚Äč‚Äčover 10 hectares. It is expected to produce more than 30 million flowers per year, and the annual output value can exceed more than 40 million RMB.
