The grower can plant the taste of the tomato that consumers want to eat. This scene took place in the Smart Agriculture Industrial Park in Tianqu New Area, Dezhou City, Shandong Province. During the Spring Festival, the news of "tomato can be customized with new taste" in the park was on the hot search. What is a "customizable new taste" tomato? How is it produced? Fu Wenqi, the technical engineer of Dezhou Caijin Intelligent Agricultural Technology Co., Ltd., told the reporter of Science and Technology Daily that we can improve the taste of tomatoes with technology and increase the yield. In the plant factory, which covers an area of 33.6 hectares and is equivalent to 47 football fields, Fu Wenqi combed the growth journey of a "customizable taste" tomato to the reporter. "Five sweet and one sour are the best sugar-acid ratio of tomato taste." Fu Wenqi said that in order to achieve this taste, it is necessary to combine seeds with sunshine and rain. In the park, technicians planted a seed. When the humidity was about 90% and the accumulated temperature reached 88 ℃, the seedlings germinated. The 8-hour "sunshine bath" every day makes it grow vigorously - the vine climbs 2.5 cm every day, and the fruit is bred. The key to the formation of sugar is water, fertilizer and light. Every morning, when the sun rises, the irradiation sensor will start to track. When the accumulated light reaches 100 joules per square centimeter, the irrigation system will be triggered, and the goal of watering 100 ml of nutrient solution for all plants will be completed in about three minutes. The concentration of carbon dioxide is related to the yield of plants. When the breeze comes, the sensor senses the wind force and direction, the changing angle of the canopy skylight, and the internal and external air are integrated in time and quantity. Temperature changes affect the fruit growth process. When the temperature rises and the humidity drops, the weather box sensor receives the signal, the controller sends the command, the sunshade closes, and the high-pressure spray sprays dew. When night falls, the water and fertilizer machine will be used for regular and quantitative irrigation, and the geothermal air duct machine will be started to resist the severe cold with warm current. In addition, the application of soilless cultivation technology, bumblebee pollination technology and green prevention and control technology makes the fruit safer and fresher. And this intelligent and digital planting mode has made tomato fruit more than 20 ears, and the yield is 3 to 4 times that of ordinary greenhouse. So, how is the above planting environment realized? The reporter noticed that there are nearly 700 sensors of all kinds in the plant factory, and more than 1700 controllers can generate more than 20 million data every day. The automation took over the green factory. Hou Lixia, a researcher at the Vegetable Research Institute of the Shandong Academy of Agricultural Sciences, who has dealt with tomatoes for nearly 30 years, told the reporter: "From the perspective of taste, it can be divided into two categories, namely, tomatoes with more sweet taste or tomatoes with more sour taste." Hou Lixia said that to achieve the goal of sweet and sour tomatoes, variety selection and planting are very important. The reporter learned that the new variety of "Jiahong 100" developed by Hou Lixia and her colleagues has been transferred to the enterprise with a technical service fee of 1.5 million yuan in the past two years, and won the gold prize of "Zhejiang Excellent Tomato Selection" in 2021. Its sweet and sour taste is widely popular in the market. (Outlook New Era)
