Introduction to Rice and Soybean

I. Rice

1. Rice originates from China and India, and as early as seven thousand years ago the ancestors in China's Yangtze River basin had already cultivated rice. The common types of rice we generally see include indica and japonica rice, early and mid-to-late rice, and glutinous and non-glutinous rice; these are all varieties that are frequently eaten in daily life. Although other classifications of rice are not common, they also have their uses.

2. Rice is currently one of the staple foods for half the world's population. Besides being eaten as everyday rice, it can also be used to brew alcohol, make sugar as an industrial raw material, and rice husks and rice straw can be used as livestock feed. China's main rice-producing areas are mainly the Northeast region, the Yangtze River basin, and the Pearl River basin. Rice is a direct cash crop, and cooked rice is the staple food of residents in Northeast China and southern China.

II. Soybean
