CCTV.com News: Produce more grain and produce good grain, seeds are the key. Dingxi, Gansu is not only the main production area of commercial potatoes in my country, but also one of the largest breeding bases for detoxification seed potatoes in China. The "seeds of seeds" of potatoes are called the original seeds of potatoes, but the original seeds of most potatoes are not planted in the soil, but are cultivated by soilless .
reporter Li Weimin: potatoes, we often call them potatoes, but look at my right hand, the original seeds of these potatoes do not grow in the soil. This is the production method of soilless cultivation potato seeds used by this base. In fact, it has many benefits, one of which is that it has more balanced nutrition. For example, in this greenhouse, nutrient solution will be automatically sprayed every 7 minutes. It can be said that these potatoes are born in their original seeds. Secondly, soilless cultivation can prevent the intrinsic seeds of potatoes from being affected by diseases in the soil, ensuring that they comply with the national technical standards and requirements for intrinsic seeds of potatoes.
The original seed of potato can also be said to be the "seed of seeds" of potatoes. The original seed is the seed potatoes produced initially by transplanting or cuttings with detoxified test tube seedlings, which are relatively small in size. The harvested potato seeds are called raw potato seeds. Farmers plant the original seeds and harvest the commercial potatoes sold to the market. Although the original seed is small, the technical content is not low, and the price is sold in every bite.
Director of Dingxi Potato Research Institute Li Jinfu: Our varieties are divided very carefully. For example, there are two special varieties of French fries. The output produced here is about 10 million pills a year.
At present, there are 34 potato seed potato production enterprises in Dingxi, Gansu, with annual production of more than 2 million tons of detoxified seed potatoes and more than 1.2 billion original seeds. The local area also continues to breed new potato varieties based on the characteristics of high yield, drought resistance, variety segmentation, etc. As of the end of August, Dingxi City has produced 780 million original potato seeds this year.
