High ridge cultivation: high ridge cultivation on both sides of the soil, can increase the living soil layer, the soil part of the rhizome is loose, which is conducive to stem extension, and can increase the ground temperature to meet the temperature required for early root development.
Formulated fertilization: Potato requires a large amount of nutrients throughout the growth and development period, and must be formulated to meet the demand for nitrogen, phosphorus, potassium and trace elements in crop growth and development, especially in the tuber expansion period, which can greatly increase the yield.
To the flower buds: the available parts of the potato are underground tubers. The flowering of the buds consumes a lot of nutrients. In order to obtain high yield, it is necessary to see the buds to remove the nutrients to promote the growth of the tubers.
Less shovel and more straight: The succulent roots of the potato can grow horizontally in the soil. It is often cut off by the shovel to cut off the roots of the flesh and artificially reduce the production. Therefore, it can only be shovel-free, combined with the pressing of the soil and the manual extraction. Grass shortage can effectively increase production.
Magnesium-promoting production: Experts have shown that during the growth of potato, especially during the expansion of potato tubers, such as sufficient magnesium fertilizer, not only high yield, but also starch accumulation and good quality, so when the plant height is 45 cm, use Magnesium sulfate is applied after the water is dissolved.
Foliar spray fertilizer: In the case of applying the base fertilizer, 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, and 1000 times triacontanol mixture are sprayed once every 10 days from the leaf. Even spraying 3 to 5 times can significantly increase production.
If it can be supplemented with sun-breeding, only one strong bud will be left per plant, and the seedlings will be taken up to ensure the yield will be further improved.
