Study on Application Technology of Bacillus amyloliquefaciens B1619 in Promoting Healthy Growth of Tomato Seedlings

【Objective】 To study the comprehensive effects of Bacillus amyloliquefaciens B1619 on growth promotion and disease prevention of processed tomato seedlings in the hope of providing a set of healthy, ecological and green management technology for the cultivation of robust seedlings and for the promotion of healthy development of processed tomato industry in Xinjiang. 【Method】 The effects of Bacillus amylolitica B1619 to growth of tomato seedlings and the prevention of seedling diseases were studied with matrix mixed medicine and spray method through laboratory experiment of hole dish seedling at seedling stage. 【Result】 The Bacillus amylolitica B1619 improves seedling emergence rate, promote growth, prevent and control damping off, its also beneficial to cultivate healthy seedlings, improve immunity, and reduce soil-borne diseases of tomato seedlings.1. Bacillus amylolitica B1619 improved the soil ecological environment of tomato seedling hole disk. The soil was loose, biomass of tomato root and seedling was significantly increased after application of bacillus compared with the control. The leaves were darker and the chlorophyll content increased. 2.Its improved immunity of tomato, enhanced disease resistance, and processed tomato seedlings had a strong role in the prevention of cataplexy. 【Conclusion】 B.amylum B1619 can improve the ecological environment of the biomass of tomato roots and seedlings; the leaf color deepens and the chlorophyll content increases. It can improve tomato immunity, enhance disease resistance, and have a strong preventive effect on cataplexy in processed tomato seedlings.
