Xin Guosheng, director of the Sweet Potato Research Institute of Yantai Academy of Agricultural Sciences, Shandong Province, a senior agronomist and a breeder of Yanshu 25, attended the 4th Central Plains Virus-free Sweet Potato Industry Development Seminar, which was summarized and commended by the 6th "Hexiatu" Cup National Sweet Potato High-yield and High-efficiency Competition, and accepted a special interview with the media, and made on-the-spot analysis on the advantages of Yanshu 25 varieties, the problems encountered in the production process and the market prospect of Yanshu 25.

When talking about the problems that should be paid attention to when planting tobacco potato 25, Xin Guosheng said: "Although tobacco potato 25 is delicious, there are also some problems that everyone should pay attention to during the planting process.

the first point is the problem of reinforcement burst, which should be the characteristic of this variety, but it can be avoided by controlling it during planting. If the plot is selected in sandy soil, semi-sandy soil and well-drained land, the reinforcement burst will be light.

the second is the high yield, which sometimes becomes a disadvantage rather than an advantage in edible varieties. Because potato chips are too big, the market character declines and people are reluctant to buy them. Therefore, the growth period of tobacco potato 25 should be controlled at about 1.51 days, and the density can be 4,511, which is very beneficial to the size control of potato pieces.

The third point is the problem that many growers can't tolerate storage, because Yanshu 25 has a high sugar content and is sweet, which people like to eat, and so do microorganisms. In order to solve this problem, we must create a condition that is not conducive to the existence of microorganisms. Therefore, after a long period of research, Yantai Academy of Agricultural Sciences has found out the conditions needed for storing tobacco potato 25, such as humidity, which is generally 85-95%, while the humidity of tobacco potato 25 is more suitable at 75-81%, and low humidity is not conducive to the survival of microorganisms. In addition, it is low temperature. The storage temperature of general varieties is 13-15 C, while the storage temperature of tobacco potato 25 is 9-11 C. In this case, it is relatively easy to store tobacco potato 25. "
