Planting potatoes in rural areas is carried out year by year, knowing the high yield of planting, but not the low yield of planting. The phenomenon of potato yield is actually very simple, without advanced knowledge. It is mainly the relationship between soil and fertilizer. Poor soil selection, argillaceous soil, very hard, poor ventilation and ventilation conditions, poor water filtration performance, potatoes are prone to disease and physiological disorders, resulting in poor growth, and ultimately affect potato production. The soil suitable for potato growth is semi Sandy and rich in humus. Loose soil with good permeability, water filtration and water retention, sandy soil with rich humus, potatoes grow well, have good quality and high yield.
The second major factor affecting potato production is fertilizer. The key fertilizers for potatoes are nitrogen and potassium. In the seedling stage, insufficient nitrogen fertilizer will affect the rooting and stem and leaf growth of potatoes. A large amount of potassium fertilizer is needed during the potato expansion period. Due to the lack of potassium fertilizer, potatoes expand slowly and have poor ability to accumulate nutrients, which will affect the volume and weight of stem blocks. The nitrogen fertilizer and potassium fertilizer required by potatoes are equally important, and the demand is basically the same. Therefore, potato base fertilizer is suitable for organic fertilizer with the same complete nitrogen and potassium, such as fermented rotten chicken manure plus plant ash, or cake fertilizer plus plant ash, etc., which is the best base fertilizer suitable for potatoes. The seedling stage is suitable for dressing human urine feces, which contains nitrogen and potassium.
In short, potatoes are suitable for sandy soil that is loose and breathable, both filtering and retaining water, rich in humus and containing the same fertilizers as nitrogen and potassium. They grow vigorously, expand quickly, accumulate more nutrients, have good quality and high yield.
