以马铃薯合作–88为材料,通过向土壤中分别加入巨大芽孢杆菌和枯草芽孢杆菌溶液,结合水分亏缺灌溉(DI)进行土壤盆栽试验,比较水分亏缺状态下细胞分裂素生产菌处理对马铃薯幼苗农艺性状、生理生化特性的影响。结果表明:加入细胞分裂素生产菌后,马铃薯的水分利用率及其抗旱特性比对照均有显著提高,加入枯草芽孢杆菌后,马铃薯的根长、根干重、根系活力和干物质储存量均比加入巨大芽孢杆菌的要高。
Potato cooperation -88 was used as the material. Pot experiments were conducted by adding soil solution of Bacillus megaterium and Bacillus subtilis together with soil water deficit irrigation (DI) to compare the effect of cytokinin-producing bacterium on the potato Effects of Agronomic Traits, Physiological and Biochemical Characteristics of Seedlings. The results showed that after adding cytokinin-producing bacteria, the water use efficiency and drought resistance of potato were significantly increased compared with the control. After addition of Bacillus subtilis, the root length, root dry weight, root activity and dry matter storage of potato Higher than with Bacillus megaterium.
