Abstract:
Four high phosphorus efficiency soybean cultivars(Jindou 33，Dahuangdou，Liaodou 13，Liaodou 16)and two low phosphorus efficiency soybean cultivars(Tiefeng 3，Jin 8-14)were adoped under three phosphorus pentoxide treatments of 0 kghm-2(Low)，82.5 kghm-2(Medium)，165 kghm-2(High)to study the effects of different phosphorus pentoxide levels on photosynthetic rate and agronomic traits of soybean cultivars.The results showed that the chlorophyll content of soybean cultivars with high phosphorus efficiency was higher than that of soybean cultivars with low phosphorus efficiency in the whole growth season，and decreased more slowly in the late growth season.At different growth stages the photosynthetic rate would be increased by phosphorus application and the cultivars with high phosphorus efficiency had a higher photosynthetic rate than that of cultivars with low phosphorus efficiency.The phosphorus pentoxide treatments had little effect on plant height，branch and node.Under low phosphorus level，the yield and traits of yield component of cultivars with high phosphorus efficiency were better than those of cultivars with low phosphorus efficiency.
