摘要： 利用盆栽试验和大田试验研究了生物有机无机复混肥对烤烟生长发育、产量以及品质的影响。盆栽试验结果表明,与施用等量NPK的普通专用肥比较,生物有机无机复混肥AA、AB和BB处理的株高增高11.2~11.4 cm、最大叶面积增加51.71~146.02 cm2,单株叶片数提高1.2~3.4片,叶绿素含量和根系活力前期高,后期下降快,以AB处理最为明显;成熟时烟株地上部干物质重分别增加16.96%,22.38%,19.44%,烟叶钾含量分别提高11.05%,12.27%,7.36%,氮含量均有所下降,施木克值、糖碱比更趋于协调。大田试验与盆栽试验结果趋势一致。

Abstract: Pot and field experiments were conducted to investigate the effects of Bio- organic- inorganic compoundfertilize on the growth, yield, and quality of flue- cured tobacco.The results showed as follows: compared to the contrast ofcommon fertilizer that contains the sameNPK quantity, in disposal AA, AB, and AB, the plant heights were more 11. 2- 11. 4 cm, the maximum leaf area was more 51. 71- 146. 02 cm2, and the number of leaves were more 1. 2- 3. 4, the content ofchlorophyll and activity of roots were speeded in the previous period, and fell more quickly in the latter period, especially indisposal AB. In the mature period, the shoot dry matter weights increased by 16. 96%, 22. 38%, 19. 44%, K content wasadded by 11. 05%,12. 27% and 7. 36%.The N content declined a little, Schmuck number and sugar/ nicotine were moreharmonious. In the field,The field experiments keeps the same with test result trend cultivated in a pot.
