Beschreibung
Zusammenfassung:	The invention relates to a biocontrol strain and application thereof in relieving plant drought, the biocontrol strain is 8141, and the preservation number of the biocontrol strain is GDMCC No: 62291. The bacterial strain 8141 is identified to be Pantoea agglomerans (Pantoea agglomerans). Greenhouse test results show that the microbial agent prepared from the strain 8141 can effectively improve the adaptability of plants to the drought environment, which is shown in that malondialdehyde (MDA) accumulated in cells can be removed by increasing the content of proline (Pro), so that the drought stress resistance of the plants is enhanced; the air hole opening degree can be reduced, and the transpiration is reduced to reduce water evaporation; the expression of drought-resistant genes NCED1 and RD29B can be regulated and controlled to regulate the drought resistance of plants; meanwhile, the growth of plant seedlings is promoted, and the influence of drought stress on plant growth is relieved. By adopting the micr
