| 【目的】探明生物活性有机肥“红土运”对番茄根结线虫病的抑制效果。【方法】室内测定生物
活性有机肥“红土运”不同浓度浸出液对根结线虫虫卵孵化的影响，以及对 2 龄幼虫（J2）的致死作用；温室
盆栽试验采用不同施肥方式，考察生物活性有机肥“红土运”对番茄植株生长状况，以及对根结线虫病的抑制
效果。【结果】120、160、200 g/L 生物活性有机肥“红土运”浸出液处理 36 h 对南方根结线虫 J2 幼虫的校正
死亡率分别达 62.6%、79.6%、84.5%，处理 7 d 虫卵孵化率仅为 6.00%、2.66%、2.67%，与清水对照差异显著。
温室盆栽试验表明，生物活性有机肥“红土运”基肥 80 g 处理与阿维菌素处理的防治效果无显著差异，抑制效
果（相对防效）达到 80.3%；表面撒施 80 g、作基肥和表面撒施各施 40 g 处理，根结指数显著降低，相对防效
分别为 56.6%、47.4%。与对照相比，生物活性有机肥“红土运”可有效增加植株株高、茎粗和地上部分生物量
及减轻植株根坏死率。【结论】生物活性有机肥“红土运”对番茄根结线虫病有良好抑制效果，为“红土运”
的推广和番茄的安全优质生产提供理论依据。 |

| 【Objective】The objective was to investigate the inhibition effect of bio-active organic fertilizer “HongtuYun” on tomato root-knot nematode disease.【Method】The laboratory experiment was conducted to determine the leachates
of bio-active organic fertilizer “Hongtu-Yun” with different concentrations on eggs hatch of root knot nematodes and lethal
effect on 2 instar（J2）larvae, and the inhibition effect of“Hongtu-Yun”on tomato plant growth and root knot nematode
disease were observed by pot experiments with different way of fertilization.【Result】After being treated by leachates with
concentrations of 120, 160 and 200 g/L for 36 h, the mortality of J2 larvae was 62.6%,79.6% and 84.5%, respectively. And after
being treated under the same condition for 7 h, the hatching rates of eggs were 6.00%, 2.66% and 2.67%, respectively. Both the
mortality and the hatching rate of all treatment groups showed significant differences in comparison with distilled water control
group.Pot experiments indicated that “Hongtu-Yun” could significantly suppressed root-knot nematode disease. The relative
control efficiency of 80 g “Hongtu-Yun” used as base fertilizer was 80.3%, which had no significant difference with that of abamectin treatment. The relative control efficiencies of other two treatments（surface broadcasting of 80 g “Hongtu-Yun”, and
surface broadcasting of 40 g “Hongtu-Yun” with 40 g “Hongtu-Yun” used as base fertilizer）were 56.6% and 47.4%, with
significant decreased root-knot index. Moreover, the application of “Hongtu-Yun” promoted the growth of tomatoes including
the plant height, the stem diameter, and the aboveground part biomass and decreased the necrosis rate of roots.【Conclusion】
The bio-active organic fertilizer“Hongtu-Yun”has a good control effect on tomato root-knot nematodes, which can provide a
theoretical basis for the promotion of“Hongtu-Yun”and the safe and high-quality production of tomatoes. |
