With Opal liquid fertilizer treatment of soil, can increase the emergence rate of soybean 9.1%. In addition to the drumming period, the rest of the growth period using the liquid fertilizer, plant height decreased, the number of branches increased, the number of pods increased, 100-grain weight decreased; while the drum-stage application, plant height, number of branches did not change, Reduce, pod number and weight increase. Comprehensive effect: Soybean Opal liquid fertilizer, grain number increased, yield increased, economic benefits. However, soil treatment and florescence spraying had the best effect, with the yield increasing rate of 11.8% and 9.6% respectively. The compounding rate was increased by 3.6% and the input-output ratio was 1: 5.3
