1、 In what season

Yam is a common food. It is very convenient to cook. There are many methods and the taste is good. It is generally planted in spring and will be available in autumn. This period is when a large number of products are on the market. Eating at this time is also good for the body. It has a lot of nutrition and can supplement health. But now because of social progress, yams can be eaten all year round

2、 Planting time

Yam is planted in many places in China. Because of the difference of regional temperature, the planting time is different. If it is planted in the open air, it is usually planted around the Qingming Festival in North China. For example, in Northeast China, it is usually planted around the first ten days of April. If covered with plastic film, the time can be advanced. As long as the temperature can reach more than 9 degrees above zero, it can be planted

3、 Harvesting method

1. Manual: dig out a pit about one meter deep with the help of a yam shovel. When shoveling to the upper end of the yam tuber, hold the upper part with your left hand, shovel the rest of the root system with your right hand, and then take it out completely

2. Mechanization: it can be operated by a small tractor and then pushed forward. This method is much faster
