At present, with the continuous improvement of people's living standards and the pursuit of beauty, the competition in the flower and green plant market has gradually intensified. How to continuously improve the yield and quality of flowers through a more mature planting system is the source problem that needs to be solved.
Chengdu Miao Duoduo Agricultural Technology Co., Ltd., located in Youai Town, Pidu District, is practicing this new road, where it is no longer "germinating and growing by the sky" but through plant tissue culture technology to make "one leaf into a forest" a reality.
No more "sprouting from the sky"
Flower varieties are selected and bred by tissue culture
Plant tissue culture technology is known as the "cloning technology" of the plant world, which is a technology that uses appropriate media to culture plant organs, tissues, cells and protoplasts in vitro to regenerate cells or complete plants under aseptic and artificially controlled environmental conditions. This technology plays an important role in the protection of endangered plants, the expansion of planting scale, breeding, etc.
Walking into Miao Duoduo Technology, rows of greenhouses come into view, and plants such as alpine rhododendrons and apple rootstocks are growing strongly. Under the leadership of Zhong Wei, general manager of Miaoduoduo Technology, Xiaobian went deep into the secret base of plants "one leaf into a forest" - tissue culture laboratory. Here, rows of steel shelves are filled with palm-sized transparent bottles, through which clusters of newborn seedlings can be seen. If you look closely, you can see the sprouts clustered together, and you can feel the joy of rebirth through the bottle.
How many seedlings can a leaf be "cloned"?
Zhong Wei said: "Plants are amazing, theoretically speaking, any part can grow into a complete plant. Even if you only get the buds, roots, stems, leaves, and petals, as long as you put them on a medium containing nutrients such as sugar, nitrogen, phosphorus, and potassium, you can quickly grow a complete plant. Regarding the number of "cloning", Zhong Wei said, "Looking specifically at the test needs, we are now mainly multiplying a small number of experiments, and some materials can achieve geometric multiplication." ”
Zhong Wei told the editor that the differentiation from plant tissues into seedlings requires careful care. A sterile environment, about 12 hours of light a day, and keeping the room temperature at about 25 degrees Celsius are the basic requirements for tissue culture. After growing into adult seedlings, the tissue culture seedlings are "domesticated" through greenhouse planting, and the tissue culture seedlings can be sent to the farmers' fields for planting.
Focus on the research and development of new varieties of rhododendrons
Let the world see the beauty of Chinese rhododendrons
At present, Miaoduoduo Technology has more than 200 varieties of rhododendrons, which can cultivate tens of millions of seedlings a year. Among them, the selection of wild original species in Guizhou, Yunnan and other places, the use of European flower production and breeding technology to successfully develop the alpine rhododendron, through tissue culture technology to achieve large-scale production, a wide variety, rich flower color, perennial to all parts of the country for stable supply.
Zhong Wei introduced: "The company mainly develops and produces new varieties such as rhododendron, woody hydrangea, and vermilion, among which rhododendron is the majority. ”
The reason why Zhong Wei focuses on the research and development of rhododendron varieties is because he was born in Pidu and grew up in Pidu's "Juan City" feelings.
"I want to create our own business card in Pidu, so I will vigorously develop rhododendron varieties, and at the same time, I want to develop more marketable and competitive varieties to increase the income of local farmers. Zhong Wei revealed that this year, the company has received orders from all over the country, and the current orders have been scheduled until 2025.
For the 2024 Chengdu World Horticultural Expo, Zhong Wei said that he is very much looking forward to it and has made full preparations for the arrival of the Chengdu World Horticultural Expo.
Zhong Wei said: "In fact, I was engaged in seedling sales and seedling engineering at the earliest, and it was also because I participated in an international exhibition and was inspired to transform into seedling research and development. ”
The Chengdu Horticultural Expo is a good opportunity for us entrepreneurs in the flower industry, others can learn about the characteristics of our local varieties in Chengdu, and at the same time, we can also discuss the cultivation technology and development direction of flowers with international researchers, which is a good opportunity for us.
This agricultural technology company, which has only been established for 5 years and focuses on the research and development of new varieties of rhododendrons, has become a comprehensive garden enterprise covering the whole industry chain of greening and enjoying a national reputation. Zhong Wei said that the process of collecting rhododendron varieties is very long, and R&D and production are also a process that needs to endure loneliness, and he will continue to collect more varieties and develop more new products.
"The new varieties we have developed will also be exported abroad, so that the world can see the beauty of our Chinese rhododendrons. Zhong Wei is full of confidence.
