Tail buds: Tests have proved that after the potato's tail buds become plants, the yield is only 1/3 of the nape buds or lateral buds. For this reason, the tail buds should be discarded when cutting seed potatoes.

High-ridge cultivation: High-ridge cultivation with soil on both sides can increase the living soil layer and loosen the soil on the rhizome, which is conducive to the extension of the stem and can increase the ground temperature to meet the temperature required for early rhizome development.

Formulated fertilization: Potatoes require a large amount of nutrients throughout the growth and development period, and formula fertilization must be used to meet the needs of crop growth and development for nitrogen, phosphorus, potassium and trace elements. Especially during the tuber expansion period, the yield can be greatly increased.

Removal of flower buds: The available part of potatoes are underground tubers. The blooming of pregnant buds consumes a lot of nutrients. If you want to obtain high yield, you must pinch off when you see the buds to save nutrients and promote the growth of tubers.

Less shovel and more straight: The fleshy roots of potatoes that can form tubers grow horizontally in the soil, often because the shovel cuts off the fleshy extended roots and artificially reduces the yield, so only the shovel is not shoveled. Combination of soil pressing and manual plucking is used for prevention Grass waste can effectively increase production.

Magnesium supplementation to promote production: Studies have shown that during the growth of potatoes, especially during the expansion period of potato pieces, sufficient magnesium fertilizer will not only produce high yield, but also accumulate more starch and good quality. Therefore, magnesium sulfate is used when the plant is 45 cm high. Topdressing after dissolving in water.

Foliar spraying: in the case of applying foot fertilizer, starting from the development of the leaves, spray a mixture of 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate, and 1000 times triacontanol once every 10 days. Continuous spraying 3 to 5 times can significantly increase the output.

If it can be supplemented with sun-dried seeds, leaving only one strong bud per plant, and taking small seedlings to fill the air to preserve the seedlings, the yield will be further improved.
