Yam is a common food. Cooking is very convenient. There are many ways to do it, and the taste is good. Usually planted in spring, it will be available in autumn. This period is a period when a large number of products are on the market. Eating at this time is also good for the body, and there are many nutrients to supplement the body. But now because of the progress of society, yam can be eaten all year round.

Second, the planting time

Yam is planted and distributed in many places in China. Because the regional temperature is different, the planting time is also different. If it is planted in the open air, it will be planted in North China around Tomb-Sweeping Day every year. Like the northeast, it is usually planted around the beginning of April. If it is covered with plastic film, it can be planted in advance as long as the temperature can reach 9 degrees above zero.

Third, harvesting methods

1. Labor: With the help of a yam shovel, first dig a pit about one meter deep. When shoveling to the upper end of yam tuber, you can hold the upper part with your left hand, shovel the remaining root system with your right hand, and then take it out completely. 2. Mechanization: it can be operated by a small tractor and then propelled. This method is much faster.
