Yam is suitable for planting in those provinces.

Except the northeast and northwest regions, yam is cultivated in other provinces and regions.

Yam doesn't need high temperature, but prefers warmer temperature. The south of China is relatively warm, but in the north of China, there are also many areas where yam is grown, such as Shanxi and Shaanxi.

It is worth noting that yam is still relatively afraid of cold, so beware of frost. Once hurt by frost, even the best yam loses its own value. Before predicting the first frost, we should dig it out of the ground and store it as soon as possible to reduce the loss.

Yam is a drought-resistant crop, but it needs to be watered properly if it wants to produce high yield. Generally, before and after the first topdressing, if it doesn't rain for a long time and the soil is completely white, it should be lightly watered 1-2 times to make the soil surface moist. From summer to autumn, if the dry and hot weather lasts for more than a week, cold water should be poured in the morning to fight drought. Yam is afraid of waterlogging, so it must be drained in time in rainy season to avoid water accumulation in the field.

Extended data

1. Yam requires more land and has a longer growth cycle because of its long roots. Only once a year. Generally, its land can be selected in a place with deep soil layer and high terrain, and the upper and lower soils are consistent. The soil is acidic to neutral.

2. After adding basal fertilizer once before the whole growth process, yam needs topdressing once. Once it grows to a length of about half a meter on the ground, it can be fertilized once.
