| Abstract: | Based on the data of the maturity characteristics of spring soybeans in Northeast of China in different planting seasons and in seven ecological regions, this paper analyzed the characteristics of the days from sowing to emergence, emergence to flowering (DEF), flowering to maturing (DFM),the days from planting to maturing (DPM)and the generally varying trend of the ration between the DFM and DEF (R/V). The study provides an important scientific basis for the regionalization of soybean producing, the introducing varieties, the breeding of soybean varieties and the soybean scientific study in China. |
