摘要: 田間試驗(yàn)研究了生物有機(jī)肥對(duì)烤煙體內(nèi)氮,、磷,、鉀積累、吸收和含量的影響,。結(jié)果表明,，烤煙施用生物有機(jī)肥提高了煙株體內(nèi)氮、磷,、鉀的積累,；烤煙對(duì)氮素的積累為T3>T2>T1>ck，單株分別積累氮素5.29g,、4.84g,、4.20g、3.55g,；對(duì)鉀素的積累為T2>T1>T3>ck,，分別積累鉀素4.92ｇ、4.59ｇ,、4.58ｇ,、3.92ｇ。施用生物有機(jī)肥對(duì)烤煙氮素吸收速率的影響是50d前較對(duì)照明顯升高,；對(duì)磷素為50 d前施用50%生物有機(jī)肥的處理較對(duì)照增加,，而75%生物有機(jī)肥的處理則較對(duì)照低；對(duì)鉀的吸收速率團(tuán)棵后逐漸增加,，50 d時(shí)達(dá)到高峰,。施用生物有機(jī)肥增加了旺長(zhǎng)期煙株體內(nèi)氮,、磷、鉀的含量,，促進(jìn)了煙株生長(zhǎng),，提高了烤后煙葉含鉀量Abstract: The field experiment were conducted to study the effect of combining application of Bio-organic fertilizer and chemical fertilizer on the N, P and K absorption of flue-cured tobacco. The results showed that，it is improved the accumulation of N, P, K in the root, stem and leaf of flue-cured tobacco. The order of accumulation of N was T3>T2>T1>ck, it was 5.29g,、4.84g,、4.20g、3.55g. The order of accumulation of K was T2>T1>T3>ck. It was 4.92ｇ, 4.59ｇ, 4.58ｇ, 3.92ｇ. The absorption velocity of N was greatly improved before 50 days after transplanted. The effect of applied 50 percent organic N of bio-organic fertilizer on the absorption velocity of P was improved than contrast before 50 days, declined by applied 75% organic N utilized the bio-organic fertilizer, it was improved especially in leaf. It was obviously heightened by applied the bio-organic on 50 days after transplant, and it was high a little at other time. It is also increased the contents of N, P, K of the root, stem and improved the contents of flue-leaf.
