When are the potatoes planted?

1, generally planted in spring (mid-late April-early May) in Northeast China, Gansu and Qinghai, and harvested in autumn. Usually only one season of potatoes can be planted in a year, which is called one-season agricultural area in the north and northwest regions.

2. Shandong, Hebei, Henan, Shanxi, Jiangsu, Hunan, Hubei and other provinces and regions plant two crops 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.

3. 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.

Extended data:

1, cutting and accelerating germination and sowing are effective measures to increase yield, which can make potato seedlings neat, complete and Miao Zhuang and increase yield. Before sowing 15 ~ 20 days to accelerate germination, generally 50 pieces can be cut per kilogram of seed potato.

2. Sow in time. The temperature is stable above 7C (usually in early March), and the seeds should be planted when the water is insufficient. Sowing before sowing, the planting density is generally 4800 ~ 5000 plants/mu.

3, rational fertilization, potato is a high-yield and fertilizer-loving crop, which is very sensitive to fertilizer. Fertilization should be based on organic fertilizer (soil fertilizer), which can not only improve the soil, but also be continuously absorbed and utilized by potatoes.

4. Field management: loosen the soil in the early stage of emergence, improve the ground temperature and promote early emergence; For the plot to be covered with film at seedling stage, it is necessary to assist in breaking the film in time; After all potato seedlings are produced at seedling stage, the main goal is to promote the growth and health of seedlings, and the key point of management is not to dry or water.
