Lima beans are a coarse grain crop, also called quinoa. Quinoa is mainly native to high-altitude areas such as the Andes Mountains of South America, Bolivia, Peru, and Ecuador. Adapt to different planting environments and tolerate low temperature, drought, saline-alkali, and barrenness. Quinoa has been cultivated for approximately 7,000 years. Because it contains a variety of nutrients needed by the human body and has a balanced proportion of amino acids, it has high edible value and health care value. As a specialty crop in the 1990s, it was highly praised by nutritionists and began to transform from a regional traditional food to a global commodity. In 1987, China introduced and cultivated it in a small area by the Tibet Academy of Agricultural and Animal Husbandry Sciences and the Tibet Academy of Agricultural Sciences, and achieved success. At present, small-scale planting has been carried out in high-altitude areas in Gansu, Qinghai, Shanxi, Shaanxi, Henan, Jilin, Hebei, Inner Mongolia and other provinces.
