The results showed that the plant growth regulator Cc could reduce plant height, root activity and total root length increased, the dry weight of the underground increased by 18.40% -31.93%, and the shoot dry weight increased by 6.58% -15.79 %. Micronutrient micronutrients Mi increased soybean plant height and leaf area, and the above-ground and belowground dry weight increased by 8.5% -13.16% and 11.31% -15.35% respectively. Insecticidal fungicide Ki Soybean diseased plants decreased by 20% -2.5%. The low concentration of Ki increased the germination rate of soybean and the root activity increased by 3.95% -14.47% and 5.32% -14.41%, respectively. , High concentrations of Cc, Ki on the emergence of soybean adverse
