Potato planting and harvesting time in Shandong

Potato planting time in Shandong

Potatoes in Shandong are suitable for planting in spring, generally about 30 days before the late frost, when the temperature is stable at above 5 degrees. In areas where the purpose is to grow commercial potatoes, early planting can be achieved in order to avoid being affected by frost damage. The specific sowing time can be determined according to local climatic conditions.

Potato harvest time in Shandong

Potatoes in Shandong are usually sown in spring. The potato seeds are planted in a greenhouse in early April each year. When the potato seedlings grow to 2 inches high in early May, they are transplanted to the field. The early potatoes can be harvested in mid-June.

Key points for high-yield potato planting in Shandong

1. Site selection and land preparation

Potatoes are suitable for planting in fertile and loose fields, among which sandy soil is very suitable for potato growth. When plowing the land, try to dig as deep as possible, then fine the soil and apply an appropriate amount of base fertilizer. This can eliminate weeds in the field, prevent various diseases, and is more conducive to the healthy growth of potatoes.

2. Germination

Before sowing potatoes, they must be germinated. When the potato sprouts grow to about 1.5 cm, they can be moved outdoors to dry for a week, and then the potatoes can be cut where they sprout. One potato can be cut into about 3 pieces depending on the germination situation. Then, dip them in wood ash and you can sow them.

3. Planting seeds

When sowing, the thickness of the soil should not be less than 12 cm. If the soil covering thickness is not enough during sowing, after the potatoes emerge, you can add soil 1-2 times according to the growth of the seedlings. If the soil covering is too little and the ground temperature changes drastically, the runners will easily break out of the ground.

4. Field management

Shandong potatoes should be weeded in time during their growth period, but the rhizomes of the potatoes should not be pulled out, especially during the flowering period. If the rhizomes are loose, the quality and yield of the potatoes will be reduced. In addition, farmyard manure should be applied once during sowing. During the flowering period of potatoes, appropriate amount of fertilizer should be applied to improve the quality and yield of potatoes.
