本研究结果表明:(1)饼肥、生物有机肥处理地下害虫危害率较高,而饼肥及农家肥处理区地下害虫危害率较低;(2)烟青虫的发生可能与肥料处理无关;在蚜虫种群密度较小的情况下(房县烟区),饼肥及农家肥处理区中蚜虫数量相对高;而在种群密度较大时(保康烟区),不同肥料处理区没有明显差异;(3)病毒病发生可能不受肥料处理的影响;(4)生物有机肥处理可能会加重黑胫病的发生;(5)在烟草旺长期,生物有机肥处理区炭疽病和气候斑点病的发生和流行较重;在烟叶成熟期,饼肥处理区气候斑点病发生较重;饼肥、饼肥及农家肥、农家肥处理赤星病发生较重.

The results of this study show that:(1) cake fertilizer,bio-organic fertilizer processing of soil pests against higher rates,and the cake fertilizer and farmyard manure handling area of soil pests endanger the low rate,(2) the occurrence of smoke Cabbageworm and fertilizers may be unrelated to treatment in the aphid Population density of smaller cases (the county breathing),cake fertilizer and farmyard manure handling area in the relatively high number of aphids and in the larger population density (Baokang breathing),dealing with different areas of fertilizer no obvious difference (3 ) Virus disease may not be dealing with the impact of fertilizers,(4) bio-organic fertilizer processing may increase the incidence of disease and tibia (5) in long-term tobacco-wang,bio-organic fertilizer handling anthrax and climate zones dot the occurrence of disease and Heavier popular in the tobacco leaves mature,cake fertilizer processing zone climate spot disease heavier; cake fertilizer,cake fertilizer and farmyard manure,farmyard manure handling brown spot disease heavier.
