| 摘 要： | 从加工番茄根际土壤中分离到两株具有促生拮抗作用的芽孢杆菌SL-23和SL-44.分别用两株芽孢杆菌的发酵液处理番茄的立枯丝核菌菌片,其电导率与呼吸强度均出现先升后降的变化.在防治加工番茄苗期立枯病的盆栽实验中,芽孢杆菌SL-23和SL-44的防治效果分别可达49.96;和20.65;.而化学试剂五氯硝基苯的防治效果仅为0.81;.种子发芽试验和幼苗促生试验表明,芽孢杆菌SL-23和SL-44可促进加工番茄幼芽和苗期的生长,分别提高发芽率12.5;和18.75;,苗期SL-44的促生效果尤为显著,植株鲜重和干重的增加量分别可达70.9;和53.14;.

| Abstract: | Bacillus sp.strains SL-23 AND SL-44 that can promote growth and suppress diseases of processing tomato were selected from processing tomato rhizosphere soil.The electric conductivity and respiratory intensity of Rhizoctonia solani mycelium treated by SL-23 and SL-44 were ascending and then descendent.In the greenhouse experiment,strains SL-23 and SL-44 showed 46.96% and 20.65% control effeciency to control Rhizoctonia rot of processing tomato,respectiely.While the control effeciency of the PCNB only was 0.81%.In germination test and the seedling stage test,the 2 Bacillus sp.strains can promote the growth of processing tomato sprouts and seedlings.Germination rate was increased by 12.5% and 18.75%,respectively.Especially the strain SL-44 can increase weight of fresh matter and dry matter of plant by 70.9% and 53.14% in the seedling stage,respectively. |
