At present soybean weeds mainly rely on the addition. Therefore, the further chemical weed control of soybean fields is the key to the prevention and control of the entire farmland weeds. It is also an important step for the steady development of agricultural production. Soybean has strong resistance and wide adaptability and is distributed throughout the country, making it the fourth largest domestic crop. Weeds and soybean in the field of synchronous growth, especially in the period of vegetative growth of soybean, mostly for the rainy season, polar weeds in the field harm, showing weeds unearthed quickly, many kinds of density, fierce, up to
