When will the sweet potatoes planted in the countryside be harvested? What problems should I pay attention to when harvesting?

Sweet potato is not afraid of continuous high temperature, ultra-low temperature, drought and water immersion. It can survive in the wild at a high temperature of 30 degrees, and it can not rain for two months in a month. But if soaked for a long time, sweet potatoes will undergo qualitative change, taste change and rot. If the temperature is extremely low, the growth will slow down or stop below 15 degrees, and the leaves and stems will be freeze-dried below 5 degrees, and the sweet potato will be frozen and rotten. Sweet potatoes can be harvested when the outdoor night temperature is as low as 10 degrees. Sweet potatoes are planted for a long time.

Considering the different climatic conditions in different parts of the country, the planting time of sweet potato is also different, so it is logical that the perfect time of sweet potato is different. In North China, if frost comes early, potatoes should be harvested early, and then cut to dry or stored. For example, it is more suitable for Henan Province to get potatoes in the middle of June 5438+10, and strive to get them before first frost. Frost and cold come late in the south, and the ambient temperature is relatively high. In order to improve the efficiency, the acquisition time can be delayed accordingly, and potatoes can be dug from 1 1 to 12 in time.

In short, it needs to be completed before the frost and cold come, and the sooner the better, as long as we still need to dry, cut and store in the kiln. Generally, the best time to obtain sweet potatoes is from the middle and late June to the middle and early June of Gregorian calendar 1 10. As long as we ordinary people want to conclude that getting sweet potatoes is neither unreasonable nor planting winter wheat by mistake, then we can achieve a win-win situation. Generally speaking, the judgment of the maturity of sweet potato depends on the working experience of our people.

If it is purely from sweet potato seedlings, it is difficult to distinguish it immediately. The planting time of sweet potato varies from place to place, so there is a certain gap in the length of maturity. If sweet potatoes are planted in May, the perfect time period is similar to that in the middle and late September. If sweet potatoes are planted in June, the perfect time will be1mid-to-late October. Generally speaking, sweet potatoes will be fully harvested in 10, which is the best time.
