Visit the magical "plant factory"

Chengdu Agricultural Science and Technology Center, located on the bank of Xinglong Lake

On June 22, a magical "plant factory" was hidden in the high -rise building between the National Chengdu Agricultural Science and Technology Center, a magical "plant factory".

Although the factory is small, the "five internal organs" are all available. Open the door of the plant factory building, I saw that the room was shrouded in colorful halo, 8 -story cultivation rack, and a cluster of green plant seedlings on the shelf. Lettuce, rapeseed, rice, wheat, etc. Nutritional liquid cultivation technology is used for three -dimensional planting. The fresh air system and carbon dioxide supply system in the house can regulate the indoor temperature and gas environment, and the nutritional fluid circulation system is the moisture and mineral required for plant growth and development.

Yang Qichang, the party committee secretary and deputy director of the Institute of Agricultural Research of the Institute of Agricultural Sciences of the Chinese Academy of Agricultural Sciences, told reporters: "The environment and nutritional elements of plants can be simulated in the environment of the plant factory, and according to the plant's demand for light environment and root nutrition , Intelligent regulation from the LED light source and nutrient solution supply system. At the same time, the daily temperature, humidity, carbon dioxide and other environmental factors can also be adjusted according to plant needs. " The demand for light has become the "little sun" of small green seedlings.

In the entire environmental control, light management is a key element. Yang Qichang said, "Plants' demand for light includes light intensity, spectrals, and light cycles. According to the accurate regulation of the light environmental elements of different growing periods, it is equivalent to customizing exclusive 'light recipes' for plants."

Yang Qichang pointed to the LED light source at the top of the cultivation rack and introduced to reporters, "This is the alternative of sunlight, which can regulate the intensity and spectral distribution of the light, and provide the most suitable light environment elements during different growth periods of the plant. solid."

The magic of the plant factory is that it presses the fast -moving key for crop growth, which helps scientific researchers to achieve rapid breeding in a limited time and develop more scientific research results.

"In the field environment, it takes 120 days to 160 days from seedling, planting, and harvest. In the plant environment, it only takes about 60 days from sowing and seedling to harvest. The time and cost saving breeding workers. The taste and quality are not different from the field environment after passing the test. "Yang Qichang introduced that the plant factory is not restricted by regional and space. It can reach more than 10 floors, using space to the greatest extent to save the time cost of breeding scientists.

This is the "Smart LED Plant Factory" studied by Yang Qichang's team. It is a kind of environmental elements such as the temperature, humidity, light, carbon dioxide, nutritional nutrition and other environmental elements in the room under the conditions of completely closed factory, to achieve refined plant production of plant refined production For advanced agricultural forms, leafy vegetables, fruits and vegetables, medicinal plants, edible flowers, etc. can be planted in plant factories.

In the corner of less than one square meter in the living room, a small device is filled with the vegetables cultivated by myself. Simple operation can meet the various elements needed for plant growth. and. "Family micro -plant growth device" entered the family and created the urban agricultural form full of future sense and technology.

In the next step, they intend to provide excellent seeds for grain safety through the breakthroughs of plant breeding plus technology, followed by implanting agricultural elements into the greening of the park as part of the urban greening. "At present, rice, corn, vegetables, fruits and fruits are planted on a small area on the roof of Chengdu. In the future, they hope to promote large -scale promotion and application to allow agriculture to enter all corners of the city and allow urban residents to experience themselves to participate in agriculture. Provide a certain guarantee for the supply of food in the city, and provide effective support for the sustainable development of the city in the future. "
