/ Morning News/December 06, 2022 Guangzhou -- On October 28, more than 400 greenhouses in the Plateau modern Agriculture Industrial Park in Luhuo County, Ganzi Prefecture, looked like rows of "transparent factories". Tomatoes were scattered in red and yellow on the branches, and workers were surrounded by a "tomato forest" composed of green vines. Busy picking tomatoes that are rosy and ripe.
"The tomatoes here are guaranteed to taste good." Zheng Xiaoheng, a member of the sixth pairing support team in Luhuo County, Jinjiang District of Chengdu, said the industrial park was developed with the support and help of Jinjiang District. Why does the tomato taste here not disappoint? In a smart greenhouse in Section B of the Industrial Park, discover the secret of giving tomatoes the "taste of childhood".
Why do tomatoes on the plateau not freeze?
Luhuo County is located in the western Sichuan Plateau, with an average elevation of 3,800 meters above sea level. The average annual sunlight is more than 2,600 hours, and the temperature difference between day and night is large. In late autumn, the highest daytime temperature in Luhuo County is only 12 or 13 degrees Celsius. Supposedly, such climate conditions are very "unfriendly" to tomatoes.
It's warm like spring here. The temperature in the greenhouse is about 20 degrees Celsius, and fruits and vegetables such as plateau small tomatoes and Hall Big tomatoes are produced continuously throughout the year.
"We have created the right conditions for tomatoes to grow, so that they can be supplied all year round and the quality is guaranteed." Pointing to the greenhouse, which is 60 meters long, 12 meters wide and 4.5 meters high, Ye Qiyin, manager of Sichuan Shengkangyuan Ecological Agriculture Development Co., LTD., said the secret lies in this "coat of science and technology."
First look at the inner layer of "science and technology coat" - greenhouse plastic film. Ye Qiyin introduced that the greenhouse uses a light absorbing film with the characteristics of anti-fog, anti-drip, ultraviolet and anti-ash, which can prevent the tomatoes from getting sick due to dripping water and ultraviolet radiation on the roof.
Tomatoes are suitable for growing in the temperature range of 15 to 30 degrees Celsius, but the lowest temperature in winter in Luhuo County can reach -16 to 17 degrees Celsius. If there is no good insulation measures, tomatoes simply cannot survive. In order for tomatoes to grow properly in the cold winter on the plateau, another layer of this technological coat is called "insulation quilt," which is 7 centimeters thick and can be divided into six layers, including cotton, felt and rain proof layer. "If plastic film is' underwear ', then 'insulation quilt' is' cotton-padded jacket 'of tomato!" Ye Qiyin said with a smile.
"The greenhouse can also control the temperature and humidity, and automatically adjust the most suitable conditions for tomato growth according to the system parameters."
Jeong Hyo-heng, who often visits the park, is very familiar with the temperature and humidity control system and the integrated water and fertilizer system in the smart greenhouse. Looking at a liquid crystal display on Chung's finger, it shows the temperature, humidity and light in the greenhouse in real time.
Besides "living" well, the tomatoes in the park "drinking" well. "Our irrigation water comes from deep clean water 100 meters underground, which is pollution-free plateau mineral water." Ye Qiyin introduced, in the greenhouse, through a dense drip irrigation network, according to different growth stages of tomatoes, can use the integrated system of water and fertilizer in a timely and accurate irrigation of organic fertilizer.
To ensure the taste of tomatoes, the last link in the production line -- picking, is also important. At present, only ripe tomatoes are picked once every three days and are not expected to produce high yields.
How did "Red Fruit Fruit" become "golden Fruit Fruit"?Yao Fukang, a villager from Shrimp Latuo Village, Shrimp Latuo Town, Luhuo County, has been working in the industrial park since Zone B was put into operation, responsible for some daily field management and equipment maintenance. For Yao Fukang and his fellow villagers, tomato farming has not only changed their lives, but also provided stable industrial support for the local economy.
"In the past, it was all about growing highland barley and potatoes. Apart from the cost, I could not earn much money a year." Although Yao Fukang's family has more than 20 mu of land, but because of the lack of planting technology in the past, the yield and output value are very low, income is not guaranteed. Now he and his wife both work in the park, and with the transfer fee of their own land, the family's annual income is nearly 100,000 yuan.
The construction and operation of Plateau modern agricultural Industrial Park in Luhuo County has brought real income increase and employment opportunities to local farmers and herdsmen. Tomato has become the "golden fruit" for the local industry to take off and help farmers increase income. "It will sell!" Ye Qiyin has spent the past two days sending the tomatoes he picked to the Chengdu market, where the final price is about 15 yuan per kilogram and demand exceeds supply. With the increase of production, Guangdong, Zhejiang and other provinces of the order also increased, a tomato is flying to a further, wider market.
Luhuo County Plateau modern Agriculture Industrial Park is planned to cover an area of 5000 mu, divided into ABC three districts. Among them, Zone A is an "enclave + crowdfunding" industrial park, which is also built with the help of Jinjiang District. Luhuo County innovatively adopts the mode of "land concentration, village enclaves, leading management, shares and dividends", and has built 300 vegetable greenhouses, mainly producing highland small tomatoes. It has received a total dividend of 31.08 million yuan, helping 10,019 villagers to increase their annual per capita income by more than 800 yuan.Zone B plans to build 560 smart vegetable greenhouses in three phases, some of which have been completed and put into operation. Area C is a standardized open field vegetable planting area, covering an area of 2000 mu. In the future, while planting rapeseed and open vegetables, rapeseed oil processing plant, cold chain warehouse, agricultural technology disease and pest control center and science and technology service center will be built to provide guarantee services for agricultural production and agricultural technology, agricultural machinery and expert counseling in the county.
< P > The leader of the matching support team of Jinjiang District and the deputy head of Luhuo County introduced that the Plateau modern Agriculture Industrial Park in Luhuo County has been included in the planning of six modern agricultural industrial belts in the three river basins of Ganzi Prefecture, and is now applying for the provincial agricultural industrial Park. When the park is fully completed, it will become the vegetable supply base of North Ganzi Road.
