Abstract

Abstract:

Under greenhouse condition，this paper studied the bio-control efficiency of NBIN863 strain on
tomato root knot nematodes and its growth promotion effect and colonization ability on tomato. The result showed
that the bio-control efficiency of NBIN863 strain on tomato root knot nematode was up to 54.48%. Compared with
the blank control，the plant height，root length and total fresh weight were increased by 49.10%，43.69% and
52.50%，respectively. We found that NBIN863 strain could stably colonize in rhizophere at the concentration of
8.37×105cfu·g^-1 on the 30th day after inoculation.

Key words: Bacillus thuringiensis, NBIN 863 strain, Root knot nematodes, Bio-control efficiency, Growth promotion

摘要：

在温室条件下，研究苏云金芽孢杆菌（Bacillus thuringiensis）NBIN863 菌株对番茄根结线虫的生物防治效果，对番
茄植株的促生作用及在番茄根际周围的定殖能力。结果表明：NBIN863 菌株对番茄根结线虫的温室防效达到54.48%；对番
茄植株具有促生作用，株高、根长和全株鲜质量分别比空白对照增加49.10%、43.69% 和52.50%；该菌株能稳定在番茄根际
周围定殖，接种30 d 后，其定殖浓度为8.37×10⁵cfu·g^-1。
