| 中文摘要: |
| Bacillus pumilus 菌株隶属芽孢杆菌属，其有利于促进植物的生长和营养吸收。为探讨该菌
株对植物生长及营养品质的应用价值，将该菌株与化肥进行不同配施处理，进行油麦菜盆栽试验。结果
表明，B. pumilus 菌剂与化肥配施对油麦菜有促生作用且提高，其品质，氮磷肥与菌剂配施使油麦菜株
高、鲜重和干物质量比对照分别高26.54%、353.95% 和303.83%，根长、根鲜重、根干物质量分别高
210.18%、163.89% 和328.30%；化肥与菌剂配施对油麦菜的促生效果较单施菌剂亦有显著增加，菌剂与
化肥配施处理后维生素C 和总糖含量比对照分别高100.00% 和283.50%，同时对油麦菜中的钾、镁、钠
含量有一定的影响。另外，B. pumilus 菌株具有解有机磷及无机磷的能力，这可能是其促进植株生长的作
用机制。可见，B. pumilus 菌剂与化肥配施后的促生效果较好，可促进油麦菜的生长及其品质的提高。 |
| 英文摘要: |
| 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. |
