When is the best time to plant potatoes and when to plant potatoes?

Although potatoes are cool-loving crops, it is not beneficial to plant them too early. In recent years, some farmers started planting before the impact. It was too early, and the germinated seed potatoes were soon unearthed. In early spring, they are vulnerable to the cold in late spring. Frozen potatoes are like people who are seriously ill. It takes some time to recover slowly after recovery. Therefore, once potatoes are frozen at seedling stage, it will affect the whole season yield. Therefore, planting time should not be too early. It is best to plant spring potatoes in the field after the fright and before the vernal equinox. The specific time can be around the 167th day of the lunar calendar. When the temperature is 3~4℃ below zero, potatoes should be covered with things, such as sacks and old clothes. When it reaches MINUS 6~7℃, it should be placed in a closed room. In case of strong cold air, cover it with a little tarpaulin and film. After the weather slows down, the tarpaulin or film should be removed. The temperature of the room where potatoes are stored should not be too high, and must not be placed by the fire. Potatoes are afraid of heat, and the hottest place should not exceed 7 degrees. If the temperature is too high, many buds will grow, which will consume the nutrition of seed potatoes and easily lead to a reduction in production after planting in the ground. In short, potato seeds should be stored in winter, and the temperature should not be lower than zero.

Potato planting time potatoes are potatoes. Because of regional differences, planting time varies greatly, which can be roughly divided into the following three types:

1 It is generally planted in spring (from mid-late April to early May) and harvested in autumn in northeast and northwest regions such as Gansu and Qinghai. Usually, potatoes can only be planted for one season a year, which is called one-season planting areas in the north and northwest.

2 Shandong, Hebei, Henan, Shanxi, Jiangsu, Hunan, Hubei and other provinces and regions plant potatoes twice a year. Among them, spring potatoes were sown in February and March and harvested in June and July in Central Plains areas such as Shandong and Hebei. Sow autumn potatoes in August, and harvest in early October at10-165438+/kloc-0; Spring potatoes were sown in Jiangsu, Zhejiang and other central and southern provinces in 5438+0-February and harvested in May-June; Sow in September and harvest in February. These areas are called central plains and south-central planting areas.

Guangdong, Guangxi, Hainan, Yunnan, Guizhou and other places can plant one-season potatoes in the gap between rice harvest in autumn. Generally, it is sown in the middle and late June of 65438+1October-165438+1October, and harvested in February and March of the following year. Because the growing season is mostly in winter, these areas are usually called southern winter agricultural areas.
