Potato planting technology and management are as follows:

1. Planting time

Potato planting time varies from region to region. Northern regions generally only plant one season a year. , generally planted in spring and harvested in autumn. In the central and southern regions of the Central Plains, spring potatoes are planted in February or March and harvested in June to July. Autumn potatoes are planted in August and harvested around November. In the southern region, they are sown in October to November and harvested in February to March of the following year.

2. Cut into pieces for germination

Put the seeds in the sun 20 to 25 days before sowing, and dry them in a warm place for 2 to 3 days to remove diseased and rotten potatoes. Cut into pieces. When cutting into pieces, the top buds can be divided into two or four. Each piece of seed potato should have 1 to 2 bud eyes and weigh 25 to 30 grams. After drying the cutting edge, it can be placed indoors at a temperature of 18 to 20°C for germination. When the buds grow to about 2 cm, they can be dried under scattered light and sown after the buds become green and thick.

3. Sowing matters

When sowing potatoes, the thickness of the soil should not be less than 12 cm. If the thickness is not enough, the ground temperature will change too drastically and the seeds will easily fall from the ground. Jumped out. If you want to plant potatoes with high yield, you must plant them reasonably densely. Large potatoes should be planted sparsely, and small potatoes should be planted densely. The sowing density can be adjusted according to the local climate, soil, variety and other reasons.

4. Watering management

Potatoes are generally not watered before they bloom, unless a small amount of water can be poured in a very dry period. Start watering during the early flowering period. During this period, the potato pieces grow too fast and the water demand also increases. Watering can be carried out. Watering is done every 7-10 days according to the soil drought condition and the growth of the seedlings. Watering is continued until harvesting. About 10 days before harvest or until the stems and leaves stop growing.

5. Fertilization management

When fertilizing, you can apply farmyard manure to potatoes, or you can also apply some chemical fertilizers appropriately with nitrogen, phosphorus, and potassium. Potatoes like to absorb ammonium. The demand for nitrogen, especially potassium, is relatively large. Proper application of potassium sulfate can significantly increase potato production.
