Wolfberry Tomato: A fruitful fruit on the land in Qinghai

Author:Zhejiang University Time:2022.07.13

Wulan County, Qinghai Province, is located in the Chaidama Basin, Gobi, desert, and is lonely. In the sunlight greenhouse next to the Mohe Camel Field, it is full of lush, green leaves, yellow flowers, and red fruits. This is the fourth batch of wolfberry tomatoes in Qinghai. After careful cultivation, it is now lush, and it is fruitful on the land of Qinghai.

Is it wolfberry? Or tomato?

You must be curious about what is wolfberry tomato, is it wolfberry or tomato?

Wolfberry tomatoes are new seedlings based on wolfberry and tomato farming. From the appearance alone, wolfberry tomatoes are the same as the small tomatoes in life, but the taste is very different. After a bite, the sweet and sour taste, the meat is full, and the flavor is strong. Compared with the tomatoes we eat daily, the quality of wolfberry tomatoes has improved significantly. Among them, soluble solids, VC content, and soluble proteins are increased by more than 20%, and they are rich in green original acid.

The idea of ​​carrying wolfberry and tomatoes is not the first time that Professor Chen Liping's team of the School of Agriculture and Biotechnology, Zhejiang University is not proposed. It is far from being close to tomato, and the survival rate of conventional grafting methods is low. However, even if it is grafted, due to the differences in the anatomical structure of wolfberry and tomato -villaing system, the transportation of grafting plants is blocked, weak growth, and low yield. Production is actually in. " The research team used cell engineering technology to solve this problem and cultivate new seedlings of wolfberry and tomato.

So, why do wolfberry use as grafting pro -pro -proof instead of other crops that are closer to tomatoes?

"This is because of the current problems such as lack of low temperature resistance and poor quality in the production of tomato production, and wolfberry belonging to the family of tomato, which is compared to other grafting of the parent, has the advantages of low temperature resistance, high resistance, and high nutritional value." The research team guess to establish a cell genetic information substance communication system by grafting, which can cultivate cold -resistant tomatoes and further improve the quality of wolfberry tomatoes.

Take root on the ground of Qinghai

In 2019, Chen Liping's team began to demonstrate the planting wolfberry tomatoes in Qinghai. This is not the result of drawing a circle on the map. There is a certain fate in it.

In the process of promoting outward, Chen Liping's team first considered the distribution of wolfberry in pro -crop, "whether it is wild wolfberry or cultivated wolfberry, the distribution in Qinghai is wide", "at the same time, I want to test the resistance of wolfberry tomatoes to the resistance of tomato tomatoes What is the low temperature? "So the R & D team turned its attention to Qinghai and conducted experimental planting at the Planting Base of Kanghong Agriculture and Animal Husbandry Development Company. The final result was unexpected to the R & D team. The wolfberry tomato plant not only passed the severe winter smoothly, but also grew up with joy, and the branches were full of rosy fruits.

Of course, this is not the result of accidents. The Qinghai -Tibet Plateau is high in altitude, low temperature, in winter, the lowest outdoor temperature is below minus 30 degrees Celsius. For ordinary tomatoes, even if the temperature remains in the "sunlight greenhouse" above 0 degrees Celsius, it will suffer cold damage below 8 degrees Celsius, affecting the growth result. It is easy to pass through the winter in the greenhouse; "In summer, the eastern region is too hot. Although tomatoes are like warm crops, there is an upper limit of the tolerance of temperature. Our tomato is too suitable. "It is combined with the advantages of sunny days, sunlight strong, day and night temperature differences in the northern region, and wolfberry tomatoes come to Qinghai to enter the sea like fish, and continue to draw nutrients in a suitable environment and thrive.

However, the process of implementation is not smooth. There are always some episodes that affect the hearts of the research team far away. Chen Liping's WeChat circle of friends records such a story. At the end of March this year, Chen Liping team sent a number of new wolfberry tomato seedlings to Wulan County, Qinghai. The road is long, and you need to experience 2,500 kilometers along the way, and the 40 -hour boat and car are working hard to span more than half of China. And on the way, seedlings are facing the danger of cold harm. Although it has reached the spring season, Qinghai has a temperature of 8 degrees, minimum to minus 4 degrees. It has been traveled for nearly two days, and finally arrives in Ulan County. This is not the end of the journey. In order to meet the local epidemic prevention and control needs, tomato seedlings have been delayed in the county seat for another day. On the way to the base, who knew that there was a heavy snow, snow was besieged, and tomato seedlings were exposed to low temperature. Fortunately, after thousands of difficulties and twists and turns, this group of Miao peacefully arrived at the base.

Use technology to benefit more people

Chen Liping has always been committed to research related to plant cell engineering, creating rich and high -quality crusher and other cross flower germs. Chen Liping's team hopes to use this technology to benefit more people. They have chosen tomatoes with more common consumer audiences and wider planting area, and open up the development of wolfberry tomatoes. When talking about the research process of wolfberry tomatoes, Chen Liping recalled: "Since 2018, our team has tried to use different grafting pro -proof to cultivate a number of new varieties of small fruit types. R & D medium fruit types, extended the purpose of wolfberry tomatoes, and let it board the people's dining table. While developing new varieties, the grafting system is also constantly optimizing and perfect. The production efficiency of wolfberry tomatoes has improved. . "As the technical system matures, the cultivation of new varieties will not be limited to tomatoes. This biochemical technology will also be applied to vegetable crops such as potato, pepper, eggplant, etc., providing people with rich and diverse choices. In actual production, the high -yield and light and efficient planting methods of crops are usually two sides of contradiction, but wolfberry tomatoes take care of the two. "Now everyone wants to realize the method of planting with a simple, simple, and efficient planting. We planted it to cultivate crops in the growth season. Isn't it very good?" Professor Chen said. Practice has shown that the growth cycle of wolfberry tomatoes is more than 19 months. As long as the temperature and light conditions are appropriate, they can bloom all year round. The branches can continue to grow upwards. The total number of ears, the research team discovered the shelter cultivation in Zhejiang, and wolfberry tomatoes were transplanted in spring for 2 months. The number of ears was significantly increased by 34.76%compared with the control. On the one hand, the yield of wolfberry tomatoes is improved, and on the other hand, it effectively reduces labor and production costs, so that tomato planting is more efficient, lighter, and efficient!

At the same time, the promotion of wolfberry tomatoes is steadily promoting. In addition to Qinghai, Chen Liping's team also set up demonstration sites in Deqing and Tongxiang in Linyi and Zhejiang in Shandong to further expand the demonstration area of ​​demonstration. Different regions adopt different cultivation models. Shandong and Qinghai are mainly cultivated for people to pick and taste; Mizuki Modern Vegetable Factory in Deqing adopts modern water -saving, energy -saving, and water -fertilizer integration technology. It is equipped with IoT technology The application of control and Internet technology is suitable for large -scale planting and production of wolfberry tomatoes. At present, Linyi Base has initially conceived cooperation with Zhejiang University to establish seedlings and seedlings, and produce wolfberry tomatoes in large quantities, helping local farmers in Yimengshan District to increase production and income.

Open Chen Liping's WeChat circle of friends, every one in it records the bits and pieces of wolfberry tomatoes. She is happy to show her "baby" and pass her love, persistence and joy to more people. If there is a chance, she will strive for the fiery wolfberry tomatoes to grow throughout the land of the motherland!
