The price of five-color potatoes is high, the price is high, and the benefit is high.

The skin is black, but after cutting, the flesh is dark purple, with a taste of radish fragrance. Today, Jiaoxi Town, Jiaozhou City, Shandong Province, 60,000 mu of early spring potatoes ushered in the harvest season. In the potato arch shed of vegetable farmer Liu Shulin's family in Doujiaheya village of the town, Lao Liu rolled up his sleeves and proudly showed off one of his colored potatoes. "the yield per mu is more than 1000 jin, and although the wholesale price is 10 yuan per jin, supply still falls short of demand." Liu Shulin said.

According to Wang Yupeng, director of the town's Agricultural Science and Technology Service Center, this kind of potato, called "Black Beauty," was just introduced from the Gansu Aerospace breeding Center last year. Although its appearance is not much different from that of ordinary potatoes, it is a new variety that has been bred in space and bred scientifically. Because it is rich in anthocyanins, it has the effects of health care and beauty, so it is suitable for cooked food and raw food.

Jiaoxi Town, known as "the first town of potatoes in Shandong Province", has been supporting and cultivating potato cultivation as a leading industry. In recent years, the potato industry has expanded rapidly, and the level of the industry has also undergone a qualitative leap. In 2008, it was rated as a professional potato town by Qingdao.

Since the successful promotion of "Black Beauty" potatoes last year, the town has cooperated with the Spark Base of the Provincial Department of Science and Technology to introduce selenium-rich potato planting technology. By spraying selenium-rich foliar fertilizer, the selenium content has been greatly increased, and the cost has only increased by a few dozen yuan per mu, but the benefit has increased by 3000 to 4000 yuan. Wang Yupeng said that the technology has been successfully promoted and has been introduced into some shopping malls and supermarkets in Shandong Province. the price is nearly 10 times higher than ordinary potatoes and is still favored by consumers. This year, the town has introduced new varieties of red, white, flowers and other colors, and many vegetable farmers have planted "five-color potatoes."

In order to enhance the competitiveness of the potato industry, in recent years, the town has also explored the planting mode of "early spring potato-summer cabbage-autumn potato" in the big arch shed, which has been planted in a single field in the past. adjust to "big arch shed, small arch shed, big field" three kinds of structure reasonable matching mode, realized "more than one year cropping, anti-season planting, wrong season listing".

"in the past, potatoes were planted only for one season, which led to centralized listing, low competitiveness and low efficiency. Now products are on the market from April to mid-July, which not only increases production, but also sells at a good price. " In the potato arch shed where the harvest was finished in Songgezhuang Village, Song Tongwu, the secretary of the branch, calculated such an account to the reporter: potatoes began to be on the market before May 1 in early spring, with a price of 4 yuan per kilogram, and the average benefit was more than 3000 yuan per mu higher than that of Datian potatoes. The planting area of the Guangda arch shed in their village has reached 5000 mu, which means an additional income of nearly 15 million yuan. (Ning Xuechun, Zhao French, Zhou Zhaoshun)
