Production areas in the north gradually take over from the south as temperatures rise and rainfall in the north increases. Some vegetables were previously delayed because of weather conditions, but now they may enter the market in large volumes. This development will hasten the seasonal price adjustment. For some types of vegetable the price could rapidly drop.
The seasonal price decline is mainly a result of higher temperatures and appropriate rainfall. Spring is the peak supply season for many vegetable production areas. Market supply rapidly grows in this period. The reason that the price maintained a high position this year is a general decline in both surface area devoted to vegetable plantation and overall production volume in comparison with last year.
Meteorological predictions show that most vegetable production areas in China will have regular temperatures this year. North China will encounter strong winds and lower temperatures. The northwest as well as south China will have relatively heavy rainfall. This is not favorable for open-field vegetables. However, as temperatures rise again, the vegetable supply from north China will grow. The seasonal price adjustment is expected to speed up. The price of some vegetables has been extraordinarily high and farmers are eager to expand the surface area devoted to plantation of these vegetables, which means that the price will rapidly fall.
