Studies on the Variation of Nutrient Efficiencies and Physiological Mechanism with Different Adzuki Bena Varieties

JIA Yue-hui, Jin Wen-lin ( Beijing Agricultural College, Beijing 102206,China)  
Soil, pot and sand culture experiments were carried out of three Adzuki bena varieties which were developed in Beijing to study the differences of outputs and nutrient efficiencies. The results showed that (1) biomass?economic yields?photosynthetic rate and the content of chorophyl of Jing Nong No.6(JN6) were remarkably higher than those of Jing Nong No.4(JN4) and Jing Nong No.5(JN5). The index were effected by fertilizers supplied; (2) the significant variations were observed in nitrogen(N)?potassium(K) efficiency among Adzuki bena varieties, the efficiency of JN6 was the highest; (3) the highest N and phosphor(P) efficiencies were obtained in low fertilizer among Adzuki bena varieties;(4) The K efficiencies were increased with increment of fertilizers supplied, the enhance of JN6 was vary significant.
