First, soil preparation treatment
Before planting potatoes, it is necessary to prepare the soil in advance, and it is best to choose plots with sufficient light and convenient drainage. When preparing soil, it is necessary to ensure that the soil is soft and sprinkle enough organic fertilizer in the plot, so that the fertile soil is more conducive to the later growth of potatoes. Fertilizer is decomposed farmyard manure, which can be sown and ploughed at one time.
Second, cut the seeds into pieces.
Before planting, you need to put the potatoes in a warm environment and wait until the potatoes germinate before planting. First, cut the germinated potatoes into pieces to ensure that there are buds on each piece, so as to ensure the smooth germination of potatoes. After the potatoes are cut into pieces, dip the wound with plant ash.
Third, the planting method
After the plots are sorted out and the potato pieces are processed, they can be planted. The planting method is simple. Put the prepared potato pieces directly into the soil, and the spacing between each potato is about 15 cm. Cover with 15 cm thick soil. After planting, water should be replenished according to the dry and wet conditions of the soil to ensure that the soil is slightly wet.
growth cycle
The growth and development of potato is also periodic, which can be roughly divided into four stages:
1. Mature tubers can only be planted as seed potatoes after a period of dormancy, that is, dormancy.
2. After sowing, it depends on its own nutrition to take root and sprout into seedlings, which is the autotrophic stage.
3. After emergence, organic matter is produced through photosynthesis, and the roots absorb water and inorganic elements, forming a complete plant growth system until flowering reaches the maximum lush plant, that is, heterotrophic stage.
4. After flowering, the overground part stops growing, and the tuber expands rapidly, accumulating nutrients to maturity, that is, the tuber formation stage.
