To select the best fertilizer for green soybean production in cold area，Several fertilizers were screened in Hailun，Heilongjiang Province.Soybean Variety Suinong 14 was used in this study.The results were:The effects of fertilizer were HAAS fertilizer (an organic-inorganic complex fertilizer made by Heilongjiang Academy of Agricultural Sciences) >N-P-K complex fertilizer>Huimanfeng fertilizer (an organic fertilizer made by Xingcheng Ltd.Co)>common organic fertilizer>Shuanglu fertilizer (a trace mineral fertilizer made by Shuanglufei LtdCo)>biological potassium fertilizer.The benefits were mainly due to the increase of leaf area during flowering，the amount of root and root nodules，which promoted soybean growth and development and then resulted in more pods and seeds；the organic matter in the soil applied with HAAS fertilizer was 5.95%，a little lower than that with organic fertilizer (6%).The soil density was 0.82 g/cm3，the same as the amount of organic matter.The total nitrogen was 0.45%,and the total phosphorous was 0.16%.All these data showed that the application of HAAS fertilizer improved the soil structure and fertility；the highest green soybean yield was achieved by application of 375kg HAAS fertilizer per hectare in cold area.
