Abstract
In order to scientifically apply phosphate fertilizer ,effect of different amounrs of phosphate fertilizer on soybean growth was researched .The results showed that phosphate fertilizer sould significantly influence on soybean plant height and chlorophyll differences .On soybean dry matter accumulation were studied mainly in the flowering and podding stage ,NP3K(N 10 .13 kg・hm‐2 ,P2 O5 77 .63 kg・hm‐2 ,K2 O 60 kg・hm‐2 ) and NP2K (N 10 .13 kg・hm‐2 ,P2 O5 51 .75 kg・hm‐2 ,K2 O 60 kg・hm‐2 ) treatments compared with NP1K (N 10 .13 kg・hm‐2 ,P2 O5 25 .88 kg・hm‐2 ,K2 O 60 kg・hm‐2 ) treatment were significant .The number and dry weight of nod‐ules with the increasing phosphorus application amount increase .The strongest nitrogenase activity of NP2K was the best .The phosphorus fertilizer could significantly increase the pod number per plant ,grain number per plant and 100 grain weight ,get higher yield ,and improve the yield trait of soybean .关键词
