1、 Planting time

When planting yam, ensure the condition of temperature. It can grow on the ground above 10 ℃, so the time should ensure the temperature. It is not appropriate to be too high or too low

The planting time is determined according to the local climate. If it is selected in warm places such as the south, there is no severe cold weather in these places, so the sowing time is not fixed and there are not too many restrictions. It can be from January to May. For example, the Yangtze River basin can be selected in March, and the Huaihe River area can be slightly extended from late March to early April. In the north, planting is generally selected from March to April in spring. In North China, it can be selected in March. In the northeast, because it is relatively cold, the time can be postponed, and it can be selected around April
