摘要 [目的]为完善广西生态烟叶良好农业规范(GAP)生产施肥技术。[方法]在总氮素不变的前提下,通过使用不同有机肥,研究使用功能性有机肥与其他有机肥对烤烟农艺性状、病害、烤烟产质量的影响。[结果]在生长初期,施用功能性有机肥的农艺性状明显优于其他处理,生长后期无明显差异;使用有机肥的各處理病害分析都较单纯使用化肥的对照优异;各处理产量以对照最高,产值以施用功能性有机肥的处理最高;各处理化学成分基本处于优质烟叶范围,且以施用功能性有机肥的处理化学成分协调性最好。[结论]该研究为功能性有机肥在烤烟上的合理使用提供科学依据。

Abstract [Objective] For improving the GAP(Good Agricultural Practices) specification of fertilization in ecological tobacco producing in Guangxi.[Method] Through carried out field experiment in the demonstration area in Baise,on the premise of total nitrogen was constant,the effects on agronomic characters,disease,yield and quality of fluecured tobacco by applying different organic fertilizer in the experiment were studied.[Result] The result of experiment showed that the agronomic characters of treatment applied functional organic fertilizer were significantly better than the one using other organic fertilizers in early growth stage,but no significant difference in later growth stage.All the treatments using organic fertilizers in disease resistance were better than the check treatment which only used chemical fertilizer.The highest yield was the check treatment.And the highest output value,was the treatment using the functional organic fertilizer.The harmonic character of tobacco chemical
components of all treatments were fit the contents of high quality tobacco,and the harmonic character best was treatment using functional organic fertilizer.[Conclusion] The research could provide scientific basis for rational application of functionalorganic fertilizer in tobaccoproducing.

良好农业规范鼓励减少农用化学品的使用。关注食品安全、环境保护、工人健康、安全和福利,以危害分析和关键控制点体系(HACCP)的原理和方法,以良好行为规范来控制农业生产过程中的质量安全问题,避免农产品在生产过程中受到外来物质的污染和危害。这是保证初级农产品生产安全的预防性质量控制体系。
该试验使用的功能性有机肥主要以活性炭为原料。它被施入土壤后可吸附铵、硝酸盐、磷、水溶性离子、农药和重金属,增加土壤保水、保肥能力,降低土壤和环境污染[1-3]。同时,活性炭含有碳、氢、氧、氮及其他营养元素,可为植物生长发育提供有效养分,使得土壤含氮量和含磷量大大增加[4]。……
