"five attentions" in the introduction of Potato

Most of the potato seeds are transferred back from other places, which is actually an act of introduction. When adjusting and purchasing seeds, it is necessary to understand the factors such as latitude, altitude and climatic conditions of potato seed stem producing area, and correctly select the producing area and variety according to the introduction law of potato.

Pay attention to latitude and altitude. It is easy to succeed when introduced from high altitude to low altitude and from high latitude to low latitude. The reason is that during the growth of potato at high altitude and high latitude, the temperature is lower, the virus of potato seed stem is lighter and the degradation is slow, which leads to planting at low altitude and low latitude, which generally performs better and has a high success rate.

Pay attention to the climatic conditions. The introduction from a distant place depends on whether the climatic conditions of the introduction place and the producing area are similar, that is, whether the climate of the two places in the same season is similar or whether the climate of the two places in different seasons is similar, for example, the winter climate of the south is similar to that of the north, the temperature is close, and the rainfall is not much different. In this way, the introduction of varieties is easy to achieve success.

Pay attention to the growth period of the variety. Potatoes like light and are sensitive to light. When it is introduced from the long sunshine area to the short sunshine area, it often does not blossom, but it does not have much effect on the growth of underground tubers, while the short day varieties are introduced to the long sunshine area, sometimes they do not bear potatoes.
