| 摘 要： | 根结线虫病对烟草产量及品质性状影响的研究结果表明,受根结线虫危害后,烟叶中蛋白质含量升高,而还原糖和烟碱含量下降.根据研究结果组建了根结线虫初始密度与烟草相对产量、线虫初始密度与病情,以及病情与产量损失率之间关系的数学模型.

| Abstract: | The research results about the effect of root-knot nematodes disease on tobacco yield and quality character indicated that when the tobacco plants were damaged by root-knot nematodes, the protein content of the tobacco leaves increased, but the contents of nicotine and reducing sugar decreased. The relationship between initial density and relative yield, initial density and disease intensity, disease intensity and yield loss were studied, and these mathematics models were established. |
