　　Where does spring come from, and the water will surprise the plum blossoms.

　　"twenty-four solar term" said: "In the first month, water comes from heaven, and it belongs to wood at the beginning of spring. However, those who grow wood must also have water, so beginning of spring has succeeded in rain. And if the east wind thaws, it will disperse into rain. "

　　Rain is the second of the 24 solar terms. Every year around February 18-20 in Gregorian calendar, when the sun reaches 330 degrees, we have a rainy solar term. Since then, the temperature has risen, the rainfall has gradually increased, and everything on the earth has awakened in the rain.

　　If we say that beginning of spring is more of a prelude to spring in meteorology, everything begins to sprout in the rain and solar terms, and spring has quietly arrived.

　　【 Rain, Three Stages 】

　　In ancient times, rainwater was divided into three stages: "One stage was for rex to sacrifice fish; Second, wait for Hongyan to come; Three waiting for the grass to sprout. "

　　It means that when the solar term comes, the ice on the water surface melts and the otters start fishing. Otters like to drag the fish to the shore in turn after they are killed, which is like a sacrifice, so they have the saying of "Rex offering sacrifices to fish".

　　Five days after the rain, the geese began to fly back to the north from the south. In five days, with the rising of the earth’s sun be the spirit, vegetation will begin to sprout.

　　In this way, nature goes to the depths of spring step by step.

　　[Spring breeze wakes up the earth]

　　In Yunnan, Yunnan-Guizhou Plateau, the warm and humid spring breeze has already awakened the earth. Pink peach blossoms and begonia flowers are in full bloom on the streets of Kunming. The willows along the boathouse quietly show their buds, and the tulips open by Dianchi Lake attract many tourists to enjoy flowers and take photos.

　　In the misty spring rain, the white walls and tiles, small bridges and flowing water, bluestone roads and pedestrians in the south of the Yangtze River are all as beautiful as an ink painting.

　　But at this time, the chill of spring can not be ignored. During the rainy season, the direct point of the sun gradually approaches the equator from the southern hemisphere. At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, and the temperature rises rapidly. The warm and humid air from the ocean becomes active and gradually advances northward to meet the cold air, forming rainfall. At this time, the weather is changeable, which is one of the most frequent cold wave processes in the whole year, with cold and hot, warm and cold at first. "Spring covers autumn and freezing" is the wisdom of our ancestors for thousands of years.

　　[Spring ploughing is busy with farming at that time]

　　A year’s plan lies in spring, and busy farming is always the topic of spring. At this time, farmers from all over the country seize the farming season to carry out farming activities such as spring sowing farmland, fertilization in wheat fields, and greenhouse management and protection, and cultivate hope in the fields.

　　In Man hong cun, Menghai County, Yunnan Province, villagers are busy transplanting rice seedlings, and the sparkling paddy fields are quickly covered with rows of seedlings. Villager Lao Wu planted more than 10 acres of fields this year. In order not to delay the farming season, he chose mechanical transplanting. "It’s really convenient. It will be inserted in two hours, saving time and effort."

　　Look from south to north. In Yanjin County, Xinxiang City, Henan Province, which is known as "the first wheat in China", the wheat seedlings have not passed their ankles, and millions of acres of wheat in the county are entering the green period. From a distance, full of green. Farmers here have begun to shovel soil and cover ridges in the fields to prepare for watering the green water.

　　During the autumn sowing last year, affected by floods, some areas such as Yanjin County suffered from late sowing of wheat, and the proportion of weak seedlings was high. But Li Yuanzhi, a big grain grower, is still full of confidence. "Near the rain solar terms, the weather forecast says there will be a new round of precipitation in Henan. ‘ Spring rain is as expensive as oil ’ Precipitation is conducive to wheat turning green. " He said that although the current situation of seedlings is not as good as last year, as long as it is done well during the spring tube period, through careful watering and fertilization, it can promote the "weak seedlings to become strong."

　　China, with its vast territory, has great differences between the north and the south. While spring is sprouting in the south, it is still snowing in some areas in the north, but this does not affect people’s expectation of spring.

　　In Heilongjiang, the northernmost province, many vast black lands are covered with snow, and hardworking farmers have begun to prepare for spring ploughing. These days, members of modern agricultural machinery Farmers’ Professional Cooperative in Dongxing, Helen City are overhauling agricultural machinery and replacing worn and damaged parts. "Spring ploughing is about to begin, and we want all agricultural machinery to be ready for ploughing at any time." Liu Chunsheng, chairman of the cooperative, said that more than 7,000 mu of soybeans were planted last year, and more varieties will be prepared this year.

　　[The seeds of dreams sprout in the spring rain]

　　On rainy days, spring is already in people’s hearts. The seeds of dreams are waiting for a timely rain.

　　On February 16th, at the opening ceremony of Coral Experimental Primary School in Nan ‘an District, Chongqing, "Twenty-four solar terms of the lunar calendar" and "Winter Olympics" became high-frequency words. Tan Jin, the headmaster, popularized the symbolic meaning of the ice pier for the children, and also sent a blessing for the new semester — —

　　"In a few days, we will welcome ‘ Rainwater ’ Solar terms This solar term indicates that the geese will return, the plants will sprout and the crops will have a good opportunity to grow. I hope that our coral students will face the spring breeze and spring rain, thrive in the new semester, and constantly surpass themselves like Olympic athletes.

Artificial intelligence technology in glass greenhouse can help growers realize more efficient and automatic planting and management methods. The following is a more detailed application:

The change of environmental factors in greenhouse will affect the growth of plants. Automatic control system can automatically control the environmental parameters of greenhouse by monitoring environmental factors such as temperature, humidity, carbon dioxide concentration and illumination, so as to ensure the best growth conditions. For example, install sensors and controllers in the greenhouse, and when the temperature is too high, the controller will automatically turn on the fan to reduce the temperature; When the light is insufficient, the controller will automatically turn on the artificial light source to increase the light intensity to ensure the normal growth of plants.

Sprinkler irrigation is an important task in greenhouse, but manual operation often requires a lot of time and labor, and it is easy to waste water resources. By installing sensors in the greenhouse, soil moisture and plant growth can be automatically monitored, and the sprinkler irrigation system can be automatically controlled to achieve the best irrigation effect. For example, when the soil is dry, the system will automatically start the sprinkler irrigation system and water it regularly, and when the soil humidity reaches a certain level, the system will automatically stop the sprinkler irrigation to avoid over-watering.

The growth of plants needs light, but plants at different stages have different requirements for light. Intelligent lighting system can automatically adjust the light intensity and color temperature in greenhouse by installing sensors and controllers to achieve the best plant growth effect. For example, when plants are in the growing period and need more light, the system will automatically increase the light intensity and color temperature to promote plant growth.

Through computer vision technology, plants in greenhouses can be identified and classified by images, so as to realize automatic plant management and quality inspection. For example, a camera can be used to take photos of plants, and an image recognition algorithm can be used to detect plant information such as plant diseases and insect pests and leaf area, and to classify plants. These data can be used in decision support system to help growers make better decisions, such as adjusting fertilizer and irrigation, managing pests and diseases, etc.

Automatic harvesting and packaging technology can realize automatic harvesting and packaging process through machine vision and robot technology. By installing cameras and robots in the greenhouse, the growth status and maturity of plants can be automatically monitored and recognized, and automatic harvesting and packaging can be carried out. This can not only improve production efficiency, but also reduce labor costs and human errors.

Through the data analysis and decision support system, the data of environmental parameters and plant growth status in greenhouse can be analyzed and monitored to provide more accurate decision support for growers. For example, data analysis algorithm can be used to determine the best irrigation amount, fertilizer amount, etc. to optimize production efficiency and quality.

Artificial intelligence technology in glass greenhouse can realize automatic planting and management, improve production efficiency and quality, reduce labor cost and human error, and also reduce environmental impact and resource waste. With the continuous progress and development of technology, these applications will become more universal and intelligent. Plant image recognition strategy, such as adjusting fertilizer and irrigation amount, managing pests and diseases, etc.
