Abstract:

The effect of nitrogen fertilizer application to the absorption of nitrogen of soybean plant underthe high yield condition, taking high oil content soybean vaviety , Heinong 41 as material , was studied. Theresult showed that nitrogen fertilizer application in R 1 advanced the absorption of nitrogen and increasedthe nitrogen accumulation speed. Nitrogen fertilizer application in R 1 could put off the fastigium of nitro-gen accumulation, and improved the gross of the nitrogen accumulation. Nitrogen fertilizer application inR 1 could improve the yield and protein of seed. The absorption of nitrogen, phosphor(P 2 O 5 ) and kalium(K 2 O) for producing 100kg seed improved slightly within the range of 0- 90 kg /hm 2 . The rate among ni-trogen, phosphor and kalium was about 1 ∶0. 28 ∶0. 69 steadily. The uptake rate of kalium decreased ifthe application of nitrogen was increased any more.
