First of all, the supply of vegetables is slow. Due to the continuous rain in most parts of China this year, the main vegetable producing areas in northern China, such as Henan, Shandong and Hebei, were hit by heavy rain and suffered floods in many places. The continuous flooding of vegetable fields has caused damage to vegetables and decreased production in many places. In addition, since the autumn, cold air has hit, and hail disasters have occurred in some areas, leaving vegetables devastated and leaves smashed. Therefore, the yield is reduced, the picking is inconvenient and the transportation cost is also increased.

Second, the weather has different effects on vegetables and grains. Most vegetables are fresh and good, and the price fluctuation is also customized according to the weather. The production and sowing of vegetables are greatly influenced by seasonal factors and weather. After the cold weather in the north, the supply of vegetables is relatively tight, and most of them are planted in greenhouses. Fresh vegetables such as cucumbers, beans and tomatoes are in short supply, so prices will rise accordingly. In particular, there are so few spinach in greenhouse listed now, which leads to the high price of spinach now.

Third, the epidemic affected the increase in vegetable prices, which was also caused by the epidemic. In order to prevent the spread of the epidemic, the whole country has implemented a comprehensive blockade to control the epidemic. Generally speaking, for the farmers' market in the north, most of them rely on the supply of vegetables shipped from the south. However, due to epidemic control, transportation roads were blocked, transportation costs increased, and insufficient supply led to a sharp increase in vegetable prices. In order to keep the freshness of vegetables, it can only increase the transportation cost of vegetables, so it is not surprising to see that vegetables are so expensive now. Why do vegetables increase in price, and vegetable farmers say they can't make money? Some netizens reported that although the price of vegetables is soaring now, most vegetable farmers still report that they have not made any money. Why? According to the related reporter's report, most of the vegetables with rising prices are mainly in greenhouses, and there are not many vegetables in the season. Most of these farmers grow vegetables in the fields, and this year is a disaster-ridden year. According to the practice of previous years, it should be sown in mid-August, grow for 30 to 50 days, and then harvest in September,1October. However, the vegetables just planted this year were flooded, resulting in no output and no supply to the vegetable market, so we had to go to the south to purchase.
