In this paper, the effects of zeolite, humic acid and rare-earth compound fertilizers on the growth and development of continuous-season soybean seedlings were studied in this experiment. The results showed that this compound fertilizer had no adverse effects on the emergence and growth of soybean. Plant robust growth, increase its fresh weight, reduce disease incidence, improve fertilizer utilization. In the end, through the comparison of the formula effects, this paper initially put forward the reference formula suitable for continuous cropping soybean growth.
