优化短短芽孢杆菌施用技术对番茄和辣椒幼苗生长的影响

从不同施用方式、不同浓度及不同施用次数等方面优化短短芽孢杆菌FJAT-0809-GLX的施用技术,并研究其对番茄和辣椒幼苗的施用效果。结果表明,短短芽孢杆菌叶面喷施和灌根结合施用显著增加了辣椒幼苗的株高和茎粗,处理14d后株高净增长为20.00 cm,茎粗净增长为0.16 mm。不同浓度短短芽孢杆菌均能促进番茄和辣椒幼苗的生长,其中稀释500倍对番茄幼苗的促生效果最好,稀释10倍对辣椒幼苗的促生效果最好。短短芽孢杆菌不同灌根次数对番茄和辣椒幼苗生长的影响不同,灌根2~3次对番茄幼苗生长效果较好,灌根2次对辣椒幼苗生长效果最好。

Effect of Optimized Application Technology on Tomato and Pepper Seedling#br# Growth of Brevibacillus brevis FJAT-0809-GLX

Different application methods，different concentration and different applying times were studied in this paper to optimize the applying technology of Brevibacillus brevis FJAT-0809-GLX. And the growth promotion effect on tomato and pepper seedlings was also studied. The results showed that the combination of leaf surface spraying and root irrigation could significanyly increase the plant height and stem diameter of pepper seedlings. The net increasing of plant height and stem diameter reached 20.00 cm and 0.16 mm after 14 days treatment， respectively. Different concentrations of B. brevis FJAT-0809-GLX could increase the growth of tomato and pepper seedlings. Among all treatments，B. brevis FJAT-0809-GLX，diluted by 500 times，had the best growth promotion effect on tomato seedlings；and diluted by 10 times had the best effect on pepper seedlings. Different root irrigation times had different effects on the growth of tomato and pepper seedlings. Two or three times had better effects on tomato seedling growth. While，2 times had the best effects on pepper seedling growth.
