| 摘 要： | 采用田间、盆栽及沙培的实验方法,研究了在北京地区育成并推广的3个红小豆品种产量、养分效率的差异及其机理。结果表明:(1)京农6号(JN6)的生物产量、经济产量、光合速率和叶绿素含量显著高于京农4号(JN4)和京农5号(JN5);施肥对其产生一定影响。(2)氮、钾的吸收和利用效率品种间差异极显著,JN6的氮和钾素吸收效率和利用效率最高。(3)低肥水平下3个品种的氮素和磷素吸收效率和利用效率均最高。(4)施肥可以提高各品种钾的吸收效率和利用效率,JN6品种钾的利用效率随施肥的增加提高极为显著。

| Abstract: | 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. |
