Abstract:
According to studying the influence of shading intension and shading duration to the yield andthe yield characters of soybean.The results showed that , shading 20%from seeding to filling or to harves-ting , shading 30%and 50%from seeding to flowering or to harvesting , the number of pods per plant , thenumber of seeds per plant and the seeds weight per plant decreased significantly .In the same extent ofshading stress,with the increase of the time of shading , the influence to the yield characters was rising .Inthe same period of shading , among with the increase of the extent of shading , the influence to the yieldcharacters was rising , and the effect of shading 50% is significant comparing with the effect of shading20%and 30%, but the effect of shading between 20 %and 30%is not significant .Shading stress had someeffect on the lowest podding height , the number of branches per plant , the percent of setting and 100-seedsweight of soybean through analysis.The result showed that , the yield of plot , was significant negativelycorrelated with the time of shading intimidate of the same shading extent ,was significant negatively corre-lated with the extent of shading among the same period of shading intimidate .
