1. Shrinking planting area: The shrinking planting area of yam led to a decrease in yield and pushed up the price of yam.
2. Increased demand: residents are increasingly aware of the health value of yam, which increases the demand for yam. At the same time, the increase of yam deep processing projects has also driven the growth of yam demand, such as the production of yam powder, yam tea, dried yam and other products.
3. Seasonal factors: In some seasons, the supply of yam may decrease, leading to price increase.
4. Weather factors: Bad weather conditions, such as drought or flood, may affect the yield of yam and further push up the price.
5. Cost increase: The increase in the cost of chemical fertilizer, pesticide and labor required for planting yam makes the production cost of yam increase, which in turn leads to the price increase.
Based on the above factors, the price of yam has soared this year. If there is a specific demand for buying yam, it is suggested to pay attention to market price changes in advance, or choose other alternative ingredients to reduce consumption pressure.
