1. Soil preparation.
To ensure that potatoes can grow in the right environment, choose well-drained, organic-rich sandy soil before planting. If sandy soil is not available, it should also be ensured that the soil is loose. Deep ploughing of the soil and meticulous leveling are the basis for high potato yields.
2. Select the seed.
When cutting potato seeds, the weak shoots at the tail should be removed, leaving only the strong buds at the top. Plants that grow from the top bud are usually more robust, while the tail bud is weaker. Therefore, using the top bud as a seed helps to develop a thicker seedling, which is the key to increasing potato yields.
3. Ridge planting.
Potatoes need deep soil and good air permeability to grow. When planted in spring and fall, ridge formation increases soil thickness, raises soil temperature, improves air permeability, and prevents water accumulation. Soil cultivation is carried out twice before sealing the ridge to make the ridge wider and taller, which is conducive to the growth of potatoes.
4. Reasonable fertilization.
When planting potatoes, the use of nitrogen fertilizer alone should be avoided, and nitrogen, phosphorus and potassium fertilizers should be reasonably combined. Potatoes have a higher need for potassium and should be fertilized at a ratio of 1:05：2.5。In the process of potato growth, in addition to the application of organic fertilizer as the base fertilizer, high nitrogen and high potassium fertilizer should also be supplemented during the tuber formation stage.
5. Control growth.
When potato seedlings are ridged and flower buds appear, their growth rate should be controlled to avoid excessive lushness. This can be achieved by pinching buds, pinching tips, or spraying chlormequatin. Controlling growth helps to concentrate nutrients for the development of potatoes and prevents yield loss due to over-growth of seedlings.
6. Foliar fertilization.
In addition to base fertilizer and top dressing, foliar fertilization is also an important measure to increase potato yield. Spraying a mixed solution of potassium dihydrogen phosphate and triacosanol on the leaves, once a week, three times in a row, can effectively promote the growth of potatoes and increase yield.
