According to relevant public information, soybean 1 No.2 and soybean 1 No.2 are both futures varieties in China's futures market, but soybean 1 No.2 refers to soybeans mainly used for food, and soybean No.2 mainly refers to soybeans used for oil extraction, both genetically modified and non-genetically modified, while soybean1No.2 is mainly non-genetically modified. In fact, not only soybean oil, but also residual soybean meal will be obtained after soybean oil is pressed, that is to say, soybean oil and soybean meal are both obtained by soybean oil pressing, soybean oil is the main product and soybean meal is a composite product. It can be said that soybean, soybean oil and soybean meal are all related. With the change of price or demand, soybean oil may have a more important impact on another variety. In the futures market, the trend of soybean oil futures and soybean meal futures will inevitably affect each other. Soybean oil and soybean meal are both extracted from soybean oil. At this time, the supply of soybean oil is tight, and the supply of soybean meal will also become tight. The increase in the demand for soybean oil will promote the oil-squeezing enterprises to increase their production capacity, and the soybean meal will also increase accordingly.
