High-yield potato planting technology: planting time, cutting and germination, sowing matters, watering management, and fertilization management.

1. Planting time

Potato planting is slightly different in different places. North China generally only plants one season a year, and it is usually planted in spring and harvested in autumn. Spring potatoes in the central and southern regions of the Central Plains are planted in February and March and harvested from June to July. Autumn potatoes are planted in August and harvested around November. In the southern region, sow seeds from October to November and harvest from February to March next year.

2. Cut into pieces for germination

20 to 25 days before sowing, place the seeds in sunlight and dry them in a dry place for 2 to 3 days to remove diseased and rotten potatoes. Carry out slicing. When slicing, you can divide it into two or four parts according to the leaf buds. Each piece of seed potato must have 1 to 2 bud points and a net weight of 25 to 30 grams. After drying the wound, place it in a room with an ambient temperature of 18-20°C for accelerating. When the buds grow to about 2 cm, place them in diffused light to dry. After the buds become wider, sow them.

3. Sowing matters

When sowing potatoes, the soil thickness should not be less than 12cm. If it is not thick enough, the ground temperature will change too much and the seeds will easily fall from the field. Jumped out. Potatoes that need to be planted to increase yields must be planted reasonably densely. Large potatoes must be sparse, while small potatoes must be planted together. The relative density of sowing can be adjusted through factors such as local climate, soil layer, and type.

4. Watering management

Potatoes are generally not watered before they bloom, except when there is a severe drought, a little water can be poured. Begin watering during the early flowering period. During this period, the potatoes grow too quickly and the water consumption increases. Watering can be carried out. Depending on the soil drought conditions and the growth of the seedlings, water once every 7-10 days. Watering should be continued. Drizzle more than 10 days before picking or after the rhizomes have stopped growing.

5. Fertilization management

When topdressing, you can apply organic fertilizer to potatoes, or you can also apply some organic fertilizer appropriately, in conjunction with the use of nitrogen, phosphorus, and potassium. Potatoes love to digest and absorb ammonium nitrogen, especially potassium. Scientific and reasonable application of ammonium sulfate can increase potato yield to a certain extent.
