野大豆是国家二级保护植物。我国从南到北甚至沙漠边缘地区也有其踪迹,但都是零散分布。随着社会的发展,时代的进步,一些地方的大力开发因而影响了野大豆的生长,故在1984年,国家将野生大豆确定为珍稀濒危野生植物。而地处黄河入海口的黄河三角洲国家级自然保护区是目前我国仅有大面积拥有野大豆的地方。 Wild soybeans are two national protected plants. Our country also has its trail from south to north and even the edge of the desert, but all are scattered. With the development of society, the progress of the times and the vigorous exploitation in some places, the growth of wild soybean has been affected. In 1984, the state identified wild soybean as a rare and endangered wild plant. The Yellow River Delta National Nature Reserve, located in the mouth of the Yellow River, is the only place in China that owns wild soybeans.
