Effects based on Bacillus pumilus combined application with chemical fertilizers on the growing and quality of lettuce
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 8
Abstract
"The Bacillus pumilus strain belongs to the genus Bacillus, which is advantageous for the promotion of plant growth and nutrient absorption. The strain was treated with chemical fertilizer under different combinations to explore the application value to plant growth and nutrient quality. The results showed that B. pumilus inoculation with chemical fertilizers could impact the growth of lettuce and improved its quality. The plant height, fresh weight, and dry matter quality of lettuce were increased by 26.54%, 353.95% and 303.83% respectively, compared with the blank control group. The root length, root weight and root dry matter of lettuce were increased by 210.18%, 163.89% and 328.30% respectively. The plant growth of the combined application of B. pumilus and phosphate fertilizers also increased compared with the single agent. The content of vitamin C, total sugar with combined application of B. pumilus and chemical fertilizers increased 100.00% and 283.50% compared with the blank control group. In addition, B. pumilus had phosphate-releasing abilities, which may be the mechanism to promote plant growth. In summary, B. pumilus and chemical fertilizers could have good growth-promoting effects after application and obtained higher quality of lettuces."
