Abstract:

The experiment studied phosphorus concentration in each soybean organ and the law of phosphorus absorption under different densities and fertilizer treatments， taking Beifeng-14 as test variety and adopting 5 factors and 3 levels treatment. The results were as following： As growing of soybean， the phosphorus concentration in different soybean organ were all descending; The largest absorption rate appeared form pod-setting to pod-filling， which was 5.28mg/d individual plant， occupied 30%~50% of the whole growth period absorption; suitable density and the mixture of nitrogen phosphorus-kalium could increase the phosphorus absorption amount and rate， and also the soybean yield.
