The main reasons for the increase in vegetable prices are as follows: 1. Because Shandong, Shanxi, Henan and Hebei are all affected by heavy rain to varying degrees, Shandong, Shanxi, Henan and Hebei are the sources of vegetable supply in most parts of China. Affected by heavy rain, many vegetables are submerged, resulting in a serious decline in vegetable output.

With the cold weather, the supply of vegetables is shifting from the north to the south, from open-air vegetables to protected vegetables. However, from late September of 10 to early October of 10, there was more rain in the main vegetable producing areas during this period, and the planting, growth, picking and storage of vegetables were affected to varying degrees. The vegetable market is generally delayed and the yield is poor, which leads to the shortage of vegetable supply.

3. During the critical period of vegetable growth this autumn, extreme weather occurred in northern China, and the temperature this year was much lower than that of the same period last year, which was not conducive to vegetable growth, resulting in slow growth of various vegetables and prolonged harvest period.

4. Due to the recent continuous increase in automobile oil prices and gasoline and diesel prices, the mode of transporting vegetables is mostly operated by large trucks, and the transportation cost will increase at that time.

5. A certain hype, because the northern part of the vegetable producing area suffered from floods and low temperatures, the supply of vegetables decreased, and some vendors deliberately raised prices, which led to an increase in vegetable prices.
