The application of the Internet of Things in greenhouses has been recognized by the majority of farmers. It has also been widely promoted, and today I will take you into the Beijing-Tianjin-Hebei vegetable security base and Shijiazhuang Luquan base.
Our greenhouse planting area is one and a half acres, planting two seasons a year, and now this stubble of tomatoes is in the fruit thinning period, and it can be harvested before the Spring Festival. Director Yang, the person in charge of the base, said: The appearance of this greenhouse is similar to that of a traditional vegetable greenhouse, but "high-tech" is used in many places.
Director Yang said while opening the app on his mobile phone to show us, "Through this mobile app, you can check the growth of vegetables in each greenhouse in real time, and you can also check the temperature and humidity in the greenhouse in real time." According to the data changes in the shed, you can also remotely control the greenhouse fan and other equipment online, and adjust the temperature and humidity in the shed at any time, so as to truly realize the 'cloud' planting vegetables. ”
He said that in the past, watering and fertilizing the vegetable garden were all manual and experience. In recent years, with the integration of the Internet of Things and water and fertilizer, there are not only advanced equipment, multi-building control greenhouses, but also data analysis. In the past, in winter, the outer layer of the vegetable greenhouse was usually covered with an insulated quilt, which was rolled up manually every morning and then released in the afternoon. Rolling and putting quilts is very physically demanding, and if there are five or six greenhouses at home, they can't be finished in an hour or two. Now, the vegetable greenhouses are installed with automatic roller shutters, and it can be completed in ten minutes with the push of a button. 
In the park of the Beijing-Tianjin-Hebei Vegetable Science and Technology Evaluation and Demonstration Center, the Internet of Things technology will closely connect 20 intelligent greenhouses to form a huge network system. Our 20 greenhouses can be remotely controlled by mobile phones, or we can control our greenhouses locally with one click.
The greenhouse is a relatively closed environment, and the water and nutrients needed for the growth of crops are mainly provided by artificial irrigation and fertilization. However, traditional irrigation and fertilization methods are not only inefficient, but also easy to lead to waste of water and nutrients, and may even cause some pollution to the environment. The introduction of intelligent irrigation technology with integrated water and fertilizer provides an effective solution to solve these problems.
The integrated intelligent irrigation technology of water and fertilizer combines the two processes of irrigation and fertilization, and enables crops to get the right amount of water and nutrients through precise control of water and nutrients, so as to grow better. The application of this technology in the greenhouse can be based on the growth law of crops and the characteristics of water and fertilizer requirements, and scientific irrigation and fertilization plans can be formulated to achieve precise control.
With the Internet of Things, the greenhouse can realize intelligent from planting to production, and the complete control system and efficient data analysis platform provide a guarantee for farmers' production.
