| 摘 要： | 采用盆栽试验,研究6种不同硼肥力土壤施用硼肥对烤烟不同部位对硼的吸收积累和养分吸收的影响。结果表明,1在烤烟生长过程中,叶片对硼、氮和钾的积累量上均表现为团棵期打顶期;打顶后烟叶叶片对硼、钾含量大小均表现为下部叶中部叶上部叶茎,而氮含量则表现为上部叶中部叶下部叶茎;2土壤有效硼含量在一定值(0.56~0.75 mg/kg)时,烟叶硼、钾、氮含量随土壤硼含量的增加而增加,而高于0.75 mg/kg时,烟叶对硼、钾、氮的积累受到抑制。因此,烤烟生产中土壤有效硼丰缺值在0.56~0.75 mg/kg之间。

| Abstract: | Using pot experiment, the effect of f1ue-cured tobacco absorption of boron accumu1ation and nutrient absorption were studied with six different boron ferti1izer force soi1 app1ication of boron ferti1izer. The resu1ts showed that: ①The content of boron,nitrogen and potassium were disp1ayed rosette stage>topping stage in the process of growth; And the content of boron and potassium of the different part of 1eaves showed that 1ower 1eaf>midd1e 1eaf>1eaf>stem after topping; But the con-tent of nitrogen showed that upper 1eaf>midd1e 1eaf>1ower 1eaf>stem. ②The content of nitrogen, boron and potassium was in-creased with the content of avai1ab1e boron increased,whi1e content of the avai1ab1e boron in soi1 was 1ower than the critica1 range (0.56~0.75 mg/kg),which wou1d inhibit the absorption and uti1ization of nitrogen in tobacco p1ant whi1e content of the avai1ab1e boron in soi1 was higher than 0.75 mg/kg. So the critica1 va1ue of avai1ab1e boron in the soi1 between 0.56~0.75 mg/kg. |
