摘要:
以高油品种黑农 41 为材料研究了高产条件下, 氮肥对春大豆植株氮素吸收的影响 。结果表明,始花期施氮肥促进氮素吸收,提高氮素的积累速率 ,推迟氮素积累高峰期, 氮素积累总量增加,促进氮素向子粒分配 , 提高子粒产量和蛋白质含量 。在施氮量为 0 - 90kg /hm2范围内 , 每生产100kg 子粒,氮 、磷(P 2 O 5 )、钾(K 2 O)吸收量略增 ,三者之间的比率稳定 ,约为 1 ∶0. 28 ∶0. 69,再增加氮肥施用量, 钾的吸收比率明显下降。
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.
