The majority of potato species are transported from Heilongjiang and Inner Mongolia. Actually, it is an introduction behavior. When adjusting seedlings and buying seeds, it is necessary to understand factors such as latitude, altitude, and climatic conditions of potato stem production areas. In accordance with the introduction rules of potatoes, the correct selection of the origin and species.
First, pay attention to latitude and altitude from high altitude to low altitude, high latitude to low latitude introduction, easy to succeed. The reason is that the high altitude and high latitude potato growth during the low temperature, potato virus is relatively light, slow degradation, led to low altitude, low latitude, generally have better performance, high success rate.
Second, pay attention to the introduction of climatic conditions from distant places, depending on whether the importing place and the producing place are close to each other in terms of climatic conditions. That is, whether the climates of the two places in the same season are similar or whether the climates of the two places are similar in different seasons, such as the winter and the north in the south. The summer weather has similarities. The temperatures are close and the rainfall is similar. In this way, the introduction of varieties is easy to succeed.
3. Pay attention to the potato growth during the growth period of the variety. Introducing it from the long-day sunshine region to the short-day sunshine region often does not flower, but it has little impact on the growth of underground tubers. After short-day varieties are introduced into the long sunshine region, sometimes No potato. The temperature has a great influence on the growth of potatoes: especially in the potato period, if the soil temperature exceeds 25 °C, tubers will basically stop growing. Therefore, the introduction must pay attention to the length of the breeding period of the species, especially the southern introduction from the north, we must introduce early maturing, early maturing varieties, and strive to harvest before the temperature rise.
Fourth, attention to the selection of virus-free stem virus is one of the main causes of degradation of potato varieties, it destroys the plant's intrinsic normal function, even if other growth conditions have been met, the plant still can not grow well, will inevitably severely reduce production . The virus-free potato plants have developed root systems, strong absorptive capacity, and thick stems and leaves, which generally increase production by more than 30%. To introduce early-generation virus-free seed potatoes: early planting potatoes had a short planting time after being detoxified, had less chance of re-infecting the virus, had a very low incidence after planting, and grew more robustly than the late-generation virus-free seed potatoes, resulting in a large increase in yield. In order to produce the commodity potato and the processing potato for the purpose of planting, the secondary or tertiary detoxified potato is generally used. When introducing or purchasing seed, it is necessary to select an official seed business unit and scientific research department. At the same time, we must also ask which seed-free potato planting base was purchased, whether there is “seed certification†or “seed quarantine certificate†to avoid being deceived.
5. Note that the type of climate for the pilot planting demonstration is not the same. If the distance is far, the introduced new variety must undergo a trial planting process. After the trial planting is actually better than the field planting variety in terms of yield, quality, and resistance, it will only expand. Planting area.
