Abstract:

Taking soybean cultivar Heinong 48 as material, the sand culture with different levels of phosphorus nutrient were used to study the effect of changes in phosphorus nutrition on P accumulation, yield and quality of soybean. The results showed that the total amount of phosphorus accumulation in soybean plants of P₁(391.26 mg per pot) was significantly lower than the high phosphorus treatment (P₃₁) (988.20 mg per pot) in the whole growth period, phosphorus accumulation of other treatment was proportional to the time of the high phosphorus treatment R1-R5 was the most sensitive period of plant phosphorus accumulation; The phosphorus accumulation of grain accounts for more percentage than other organs, and the longer time of high phosphorus the lower proportion to the distribution of phosphorus in seeds, when phosphorus undernourished, the plant would give priority to satisfy the demand for phosphorus in seeds.The phosphorus levels before period of R1 in the decision of the height and the number of sections.The seeds per plant£¬100-seed weight, yield and soybean protein and fat content were increased continually with the increase of high phosphorus time. The high phosphorus treatment in V3-R1 played the most important role in enhancing the yield, R1-R5 was the most sensitive period to phosphorus stress. The sufficient P nutrition in early stage influenced yield formation. The sufficient phosphorus in late stage could compensate to yield formation when early P nutrient deficiencies.
