In the middle of the spring, in Heng County, Guangxi, the "Hometown of Jasmine in China", the outdoor jasmine field is still in the stage of spring planting. But the jasmine flowers in the "digital jasmine" planting greenhouse in the core area of the Heng County National Modern Agricultural Industrial Park are already in full bloom with fragrance and pleasure.
By opening the control cabinet installed on the wall of the greenhouse and tapping a few buttons, Ms. Nong Lili completed the cooling and sprinkler irrigation of the jasmine grown in the greenhouse.
Ms. Nong Lili is a technician in the management center of Heng County Modern Agriculture Industrial Park. Under the supervision of the agronomist Mr. Wei Yuquan, she is carrying out digital management of jasmine production in the industrial park. "For open-field cultivation, the jasmine blooming period is from April to October. Through intelligent control of greenhouse cultivation, we create an optimal growth environment for jasmine, which can realize the fragrance and bloom of jasmine in all seasons," said Ms. Nong Lili.
It is understood that in order to further improve the yield and quality of jasmine, extend the flowering period of jasmine, and promote the transformation of jasmine planting methods from extensive to fine, Heng County launched a digital jasmine production pilot project in 2019, mainly building jasmine production digital facility base, digital standard planting base, digital open-field planting monitoring base, and realizing digital precision management of jasmine growth throughout the process.
Among them, the "digital jasmine" planting greenhouse with an investment of 3.7 million RMB is installed with a full set of intelligent lighting, temperature, and humidity control systems, and monitoring and sensing equipment to simulate the different growth environments of jasmine planting. "The data collected by the sensors will be transmitted to the control cabinet in real-time, and we can obtain the jasmine growth environment data. Then by observing its growth and output, we can analyze what kind of environment is most suitable for the growth, to form the most suitable planting standards for jasmine production, so as to improve its yield and quality,” said Ms. Nong.
Nowadays, in Heng County, the flowering period of jasmine flowers planted according to the planting standards is generally extended by 1 to 1.5 months, with an increase of about 1500 kilograms per hectare, and a comprehensive increase of more than 30,000 RMB per hectare for flower growers.
In addition to the digital management of the planting greenhouse, the outdoor planting base of the pilot project is also equipped with humidity, rainfall, soil moisture, and other sensors, as well as monitoring, water and fertilizer integration, and other equipment to realize data collection, digitalization, and visualization of the production. According to Mr. Wei’s demonstration, you can see that only through a smartphone, growers can observe the flower field anytime and anywhere, understand the air temperature and humidity, soil temperature and humidity, rainfall, light intensity, and other information in the flower field, and realize fine planting and management.
It is understood that the comprehensive brand value of Heng County jasmine and jasmine tea has exceeded 20 billion RMB, making it the most valuable agricultural product brand in Guangxi. Currently, Heng County is establishing a jasmine standardized planting technology promotion mechanism under the "enterprise + base" model, allowing leading companies to lead small farmers to realize modern planting management, letting cooperatives lead scattered farmers to turn extensive management into unified control, and further to promote the construction of a standardized planting base for jasmine. Ten local jasmine processing companies have established a standardized planting base of more than 333 hectares. Through the demonstration and leadership of leading companies, new planting technologies and modern planting management systems have been further promoted throughout the county, and jasmine planting in Heng County has been promoted to be more ecological, green, and efficient, and further continue to expand the resource advantage of jasmine in Heng County.
