以花生根结线虫接种，测定感病花生植株的主要生理指标变化。结果表明，发病花生的根活力在初花期、结荚期和乳熟期几乎呈直线下降，对Ｎ、Ｐ、Ｋ的吸收普遍减少，但对Ｃａ的吸收有所增加；叶绿素含量和光合强度明显下降，但呼吸作用强度在接种后第３ｄ显著增强，随后则明显下降。 Inoculation with peanut root-knot nematode was carried out to determine the main physiological changes of susceptible peanut plants. The results showed that the root activity of diseased peanut decreased almost linearly at initial flowering stage, podding stage and milky milky stage, while the absorption of N, P and K was generally decreased, but the absorption of Ca was increased; the chlorophyll content and photosynthetic intensity were obvious Decreased, but the intensity of respiration increased significantly after 3d, and then decreased significantly.
