Potato is a tuber with high starch content and various vitamins. The fruit of a potato is a root, not a stem. The fruit of potato is a plant tuber, and the edible part of potato should be an underground tuber. Potato fruit is stem block, oblate or high15 ~ 80 cm, spherical, hairless or sparsely hairy.

The stem is divided into two parts: aboveground stem and underground stem. It is oblong, with a diameter of about 3 ~10 cm and a white, reddish or purple skin. The skin of potato is white, yellow, pink, red, purple and black, and the flesh of potato is white, light yellow, yellow, black, cyan, purple and black purple. The expansion of potato tuber and the formation of berry are contradictory in nutrient distribution, because the growth of berry and the expansion of tuber are basically carried out at the same time.

Make nutrients

The more berries there are on the plant, the greater the influence on tuber yield, which is generally reduced by 5% ~10%, and most of them can reach more than 20%. Therefore, if it is not for harvesting seeds, flowers and buds should be picked in time for those varieties with more fruits, so as to avoid the competition between berries and tubers for nutrients. Under certain conditions, potato plants grow and develop in close coordination with roots, stems and leaves. When the seedlings were unearthed, their green stems and leaves began to use photosynthesis to make nutrients.

Well-developed roots absorb enough water and inorganic elements from the soil for the growth and utilization of various parts of the plant. With the distribution of nutrients in plants and the growth and development of roots, stems and leaves, a complete plant growth system is formed until flowering reaches the maximum lush plants.
