以平板测定对小麦纹枯病菌有明显拮抗作用的５ 个芽孢杆菌菌株 （ Ｗ１２２， Ｗ１４１， Ｃ Ｂ１， Ｗ４４５， Ｔ０）， 分别按液培和土培麦苗的方式测定其对麦苗的促生性。以对小麦有明显促生效应的菌株 Ｗ２６ 作标准对照， 以清水 （ Ｃ Ｋ） 作空白对照。结果表明， 小麦液培时， 各菌株促生效应各指标的综合评价顺序为 Ｗ１２２＞ Ｃ Ｂ１＞ Ｗ１４１ ＞ Ｗ２６ ＞ Ｗ４４５＞ Ｔ０＞ Ｃ Ｋ； 小麦土培时， 各菌株促生效应各指标的综合评价顺序为 Ｗ２６＞ Ｗ１２２＞ Ｗ４４５＞ Ｗ１４１＞ Ｃ Ｋ＞ Ｔ０。
Five strains of Bacillus (W122, W141, C B1, W445, T0) which were significantly antagonistic against R. solanacearum were determined by plate culture. Nature. W2 6 was used as a standard control strain with obvious promoting effect on wheat and CK as a blank control. The results showed that in the process of liquid culture of wheat, the comprehensive evaluation order of the promoting effect of each strain was W122> C B 1> W141> W2 6> W445> T0> C K; The comprehensive evaluation order of each index is W2 6> W122> W445> W141> C K> T0.
