以“天正粉秀”番茄为试材,对其种子和幼苗进行不同浓度的短小芽孢杆菌NMCC46菌株发酵液浸种、灌根或叶面喷施处理,研究了种子的萌发率、根和芽的长度以及幼苗的株高和株重的生长情况。结果表明:短小芽孢杆菌发酵液对番茄种子萌发、根芽生长及幼苗的株高和株重具有明显的促进作用,其中以50倍稀释液的效果最为显著,而在幼苗施用方式上叶面喷施的效果明显优于灌根和浸种。该研究为该短小芽孢杆菌的进一步应用奠定了良好的基础。 The seed and seedlings were treated with different concentrations of Bacillus pumilus NMCC46 fermentation broth soaking, irrigation or foliar application. The germination rate, root and shoot Length and seedling height and weight of the growth. The results showed that the fermentation broth of Bacillus pumilus could significantly promote tomato seed germination, root bud growth and seedling height and plant weight, of which the 50-fold dilution was the most obvious. However, in the seedling application mode, Shi effect was significantly better than irrigation and seed soaking. This study laid a good foundation for the further application of Bacillus pumilus.
