There are tricks for increasing production of potatoes.

First, abandon the tail bud

The experiment showed that the yield of potato after tail bud was only 34% of that of terminal bud or lateral bud. Therefore, growers should choose terminal buds or lateral buds instead of tail buds when selecting seed-cutting potatoes.

2. High ridge cultivation

Cultivating soil on both sides of high ridge cultivation can increase the looseness of the soil in the rhizome part of the living soil layer, benefit the extension of the stolon, raise the ground temperature, meet the temperature needed for early rhizome development, and increase the yield by 11% to 23% compared with general cultivation.

Third, remove the buds

The available part of potato is underground tuber, which does not need to be fed by flowering and pollination, while budding and flowering consumes a lot of nutrients. Therefore, if you want to obtain high yield, you must pick it when you see the bud, in order to save nutrients and promote the growth of tubers. This method can increase the output by 8% to 17%.

IV. Formula fertilization

Potatoes must have sufficient nutrients throughout the growth and development period. In the fields with poor soil and low nutrient content, formula fertilization must be implemented to meet the needs of nitrogen, phosphorus, potassium and micro-fertilizer for the growth and development of potato. Especially in the tuber expansion period, the application of formula fertilizer can greatly increase the yield.

5. Foliar fertilizer spraying

In the case of sufficient base fertilizer, from the leaf expansion, 0.1% magnesium sulfate, 0.3% potassium dihydrogen phosphate and 1000 times triacontanol mixture were sprayed every 10 days, and the total yield could be increased by 21% and 31%.

6. Shovel more times less

Potato fleshy roots grow horizontally in the soil, often due to deep shovels and cut off the fleshy extended roots, that is, artificial production reduction. Therefore, after shoveling the first time, only do not shovel, with the combination of soil pressing grass and manual pulling to prevent grass shortage, can significantly increase the yield.

7. Supplement magnesium fertilizer

In the process of growth and development of potato, especially in the expansion period, if magnesium fertilizer is sufficient, the yield and starch accumulation will increase, that is, high yield and high quality can be achieved. Therefore, when the plant is 45 cm high, magnesium sulfate should be used to dissolve the water and apply it, which can increase the yield by 20% and the starch content by 2% to 4%.
