摘　　要：以番茄品种爱绿士T147幼苗为试材,研究不同浓度微生物菌剂(侧孢短芽孢杆菌、枯草芽孢杆菌、胶冻样芽孢杆菌按照体积比7∶2∶1混配)蘸根处理对番茄幼苗质量的影响,以期为定植期使用该微生物菌剂灌根提供理论依据。试验共设8个处理:清水蘸根(CK)、不同浓度微生物菌剂(分别稀释300、400、500、600、700、1 000、1 500倍)蘸根。结果表明,蘸根微生物菌剂存在浓度效应,随稀释倍数增加,番茄幼苗地上部和地下部生长均呈先升高后降低的趋势,稀释500倍效果最好,该处理下番茄幼苗株高、茎粗、地上部鲜质量和干质量、地下部鲜质量和干质量、壮苗指数、根系长度、根系表面积、根系体积、根系活力分别较CK提高3.3%、18.9%、34.0%、31.3%、22.0%、114.3%、92.9%、22.2%、33.2%、45.5%、24.4%,且差异均达显著水平。综上,用稀释500倍的微生物菌剂蘸根对番茄幼苗生长具有明显促进作用,番茄幼苗定植前可以使用该浓度微生物菌剂蘸根,促进番茄缓苗和生长。By using ‘Ailvshi T147’ seedlings as the experimental materials,this study investigated the effect of different concentrations of microbial agents(Brevibacillus laterosporus,Bacillus subtilis and Bacillus mucilaginosus in a volume ratio of 7∶2∶1)dipping roots treatment on the quality of tomato seedlings,to provide a theoretical basis for the application of microbial agents to the roots treatment during the transplanting stage.A total of 8 treatments were set up in this study:dipping roots in water(CK)and dipping roots with different concentrations of microbial agents(diluted 300,400,500,600,700,1 000,and 1 500 times,respectively).The results showed that the microbial agent treatments had a concentration effect,and as the dilution ratio increased,the growth of tomato seedlings in both aboveground and underground parts showed a trend of first increasing and then decreasing.The best dilution was 500 times.Under this treatment,the height,stem diameter,shoot fresh and dry weight,root fresh and dry weight,seedling index,root length,root surface area,root volume,and root vigor of tomato seedlings increased by 3.3%,18.9%,34.0%,31.3%,22.0%,114.3%,92.9%,22.2%,33.2%,45.5%,and 24.4% compared to CK,respectively,and the differences were significant.In summary,dipping the microbial agent diluted 500 times into the roots has a significant promoting effect on the growth of tomato seedlings.Before transplanting tomato seedlings,this concentration of microbial agent can be used to dip into the roots to promote tomato seedlinggrowth.
