Let me ask you a serious question: How much do you know about the rice you eat every day? At present, China is the largest rice producer in the world, accounting for 30% of the world's total output. China mainly produces indica rice in the south and japonica rice in the north. There are many classifications of rice. According to variety type, grain arrangement and rice quality, rice in China can be divided into indica rice, japonica rice and a small amount of glutinous rice. Among them, the yield of indica rice accounts for about 2/3, and that of japonica rice accounts for about 1/3. The main producing areas are distributed in the northeast, Yangtze River basin and Pearl River basin, and there are great regional differences among varieties. We generally like japonica rice rich in water, especially northeast rice, which has become more and more popular in recent years. After cooking, it will produce glittering and translucent luster, stickiness and softness. What kind of rice do you want? Welcome to communicate.
