Recently, in the plant factory of Weihai Hualing Optoelectronics Co., Ltd., batches of leafy vegetables such as lettuce and spinach that rely entirely on "drinking water" for growth and do not use any pesticides have ushered in the day of harvesting. Thanks to the application of the automatic circulation system, this 960 square meter indoor planting area does not require any additional manpower for fertilization, weeding, or pest control.
Huang Xiaomei, an engineer at Weihai Hualing Optoelectronics Co., Ltd., introduced that the company has built a "Technology Agriculture Planting Greenhouse" and an "Indoor Plant Factory" in its factory area, which respectively carry out fruit and vegetable hydroponic cultivation using sunlight and leafy vegetable hydroponic cultivation using LED artificial light. Through intelligent regulation and the use of nutrient solutions, scientific management of planting is carried out, and the liquid temperature, room temperature, pH value of nutrient solutions, light and ventilation of plants are scientifically controlled throughout the entire growth cycle.
Huang Xiaomei said, "The company has a self-developed hydroponic equipment that can perform automatic detection and feedback, and then make automatic adjustments to ensure that it is in the most suitable state for crop growth, thereby planting vegetables with higher yield and better quality.
As an enterprise mainly engaged in the design and production of sensors and semiconductor products, the light source used by Hualing Optoelectronics Plant Factory is independently designed and manufactured by Hualing Optoelectronics. It is an extension of Hualing Optoelectronics' light source technology and can design and manufacture suitable LED light sources for different types of plants.
All cultivation methods in the greenhouse adopt deep liquid flow soilless cultivation, which can ensure that crops fully absorb nutrients and continue to grow in the event of power failure and inability to circulate.
After one year of growth, tomato trees can reach a leaf crown area of over 100 square meters and harvest more than 8000 fruits. Without the use of hormones, the fruits naturally ripen and have balanced nutrition, with full fruit juice and flesh. A bite of them is full of rich fruit juice, "said Huang Xiaomei.
Compared to ordinary soil cultivation, hydroponic vegetables are not constrained by natural environmental conditions. From seedling cultivation to harvesting, lettuce generally only takes 35 to 40 days, greatly shortening the growth cycle. Plants can be stacked on "shelves" like commodities, without space limitations, and yields are generally 10 to 20 times higher than traditional planting. There is no heavy metal pollution in the soil, no pest infestation, and it can be directly eaten after being picked.
In addition to hydroponic cultivation, the base also innovatively uses substrate cultivation methods to experiment with planting Chinese herbal medicines. The so-called substrate cultivation refers to using coconut coir, perlite, husks, and other materials instead of soil. These substrates are softer than soil and can help the crop roots better lock in water and breathe.
At present, Hualing Optoelectronics has established a research and study base for hydroponic cultivation, combining science and technology agriculture with practical labor education. Many schools and people from all walks of life in Weihai have introduced science and technology agriculture into schools and families to experience the development of science and technology agriculture up close.
