Yes hi light potato crops, during the duration of sunshine at the growth of long, light intensity, and is conducive to photosynthesis. Cultivated potato varieties, are basically long-day types. Illumination is sufficient lush foliage, the growth of robust, easy to bear fruit, tubers, especially in large production of high plateau and high latitudes, light, and temperature suitable large potato growth and nutrient accumulation, the general access to high-yield. In contrast, under tree shade or intercropping maize and other crops, such as the time interval from the small symbiotic long corn shading, and the potato plants than short insufficient light, nutrient accumulation of small, tender stems and leaves of the weak, non-flowering, tuber small, low output. Is potato monoculture conditions, such as tall plant species, density,hours, and is often crowded with each other, the lower branches interlaced, ventilation, bad light will also affect photosynthesis and yield.
    Light can inhibit the growth of buds on tubers. Storage of tubers at cellar no light conditions can lead after a period of dormancy because of cellar temperature high, and grow a long white shoots son, such as the tubers sprout put on the scattered light, even at 15 degrees to 18 degrees temperatures, bud son grow very slowly, in southern China Tibetan seed planes (lines) and the north before sowing pregermination are using this point to curb the excessive growth of sub-bud. But also in the scattered light under the big bud seed reminder is an important output measures.
