一种哈茨木霉菌对水培生菜生长的影响和根腐病的防治方法
摘要：
本发明公开了一种哈茨木霉菌对水培生菜生长的影响和根腐病的防治方法，该方法通过用一系列浓度梯度的含哈茨木霉菌的培养液处理生菜，探究哈茨木霉菌的最佳促水培生菜生长浓度，及其生物防治效果。结果表明：不同浓度的哈茨木霉菌对水培生菜均有一定的促生长作用，0.3g·L-1至0.4g·L-1左右用量的哈茨木霉菌能促进生菜鲜重的增长率达110％以上；但是哈茨木霉菌浓度过高时促生作用反而不理想；同时，加入哈茨木霉菌的水培生菜在移至室外后，仍表现出较好的生长情况，并未出现染病症状，说明了哈茨木霉菌对植物根腐病有一定预防效果。
摘要（英）：

The invention discloses a method for preventing the influences of Trichoderma harzianum strains on the growth of hydroponic lettuce and root rot. According to the method, lettuce is treated with a series of concentration-gradient nutrient solutions containing the Trichoderma harzianum strains, and the optimal concentration for prompting the growth of hydroponic lettuce and biological control effect of the Trichoderma harzianum strains are researched. As proved by the result, Trichoderma harzianum strains of different concentrations have certain growth promotion actions on the hydroponic lettuce, the fresh weight increasing rate of the lettuce can be over 110 percent under the action of about 0.3g.L<-1> to 0.4.L<-1> of Trichoderma harzianum strains; however, when the concentration of the Trichoderma harzianum strains is over high, the growth-promoting action is unsatisfactory; meanwhile, after the hydroponic lettuce to which the Trichoderma harzianum strains are added is moved to the outside, a good growth situation is presented, and affection symptoms are avoided, indicating that the Trichoderma harzianum strains have certain prevention effects on the plant root rot.
