When is the best time to plant potatoes? Planting time of potatoes

Although potatoes are a cool-loving crop, they should not be planted too early. In recent years, some farmers have started planting them before the awakening of insects. The time is too early. The sprouted seed potatoes are unearthed quickly. Potatoes that have been damaged by freezing are like people suffering from a serious illness. It will take a certain amount of time to recover slowly after recovery. Therefore, once potatoes are damaged by freezing in the seedling stage, the yield of the whole season will be affected. Therefore, the planting time should not be too early. The best planting time for field spring potatoes is after the awakening of insects and before the vernal equinox. The specific time can be around the 16th or 17th day of the lunar calendar. When the temperature reaches minus 3~4℃, the potato seeds should be covered with something, such as sacks, old clothes, etc. When the temperature reaches minus 6~7℃, it should be placed in a closed room. If there is strong cold air, it should be covered with some tarpaulin or film. When the weather gets better, the tarpaulin or film should be removed. The temperature in the house where potatoes are stored should not be too high. They must not be placed near the stove. Potato seeds are afraid of heat, and the warmest place should not exceed 7 degrees. If the temperature is too high, many sprouts will grow, consuming the nutrients of the seed potatoes. If planted in the ground in the future, it will easily cause a reduction in yield. In short, when storing potato seeds in winter, the temperature in the house should not be lower than zero without covering anything.

Potato planting time Potatoes are potatoes. Due to regional differences, planting time varies greatly. They can be roughly divided into the following three types:

1 Northeast and northwest regions such as Gansu and Qinghai, Generally, they are planted in spring (mid-to-late April to early May) and harvested in autumn. Usually, only one season of potatoes can be planted a year, which is called the northern and northwest one-season cropping areas.

2 Shandong, Hebei, Henan, Shanxi, Jiangsu, Hunan, Hubei and other provinces and regions grow potatoes twice a year. Among them, spring potatoes are sown in the Central Plains such as Shandong and Hebei in February and March, and harvested from June to July; autumn potatoes are sown in August, and harvested from the end of October to early November; spring potatoes are sown in Jiangsu, Zhejiang and other central and southern provinces from January to February, and harvested in May. -Harvest in June; sow in September and harvest in December. These areas are called the Central Plains and Central-Southern two-season cropping areas.

3 In Guangdong, Guangxi, Hainan, Yunnan, Guizhou and other places, potatoes can be planted in the gap after the autumn rice harvest. Generally, the seeds are sown from mid-to-late October to November and harvested from February to March of the following year. Because most of the growing season is in winter, these areas are often called southern winter growing areas.
