The Purpose of Activating Bacillus subtilis
The basic principles of activation of Bacillus subtilis include the following aspects:
1. Promoting the normal growth and development of plants: Various antiviral substances released by Bacillus subtilis can promote the normal growth and development of plants.
2. Increasing plant stress resistance: Activated Bacillus subtilis can inhibit the growth and spread of pathogens, thereby enhancing plant disease resistance.
3. Improving soil quality: Bacillus subtilis can improve soil quality and structure, promote plant root development, and reduce organic pollutants in the soil.
Methods and steps for activating Bacillus subtilis
1. Choosing the appropriate activator: Organic nutrient activators or cell proliferation hormones are usually used. Organic nutrient activators help to enhance the vitality of Bacillus subtilis, while cell proliferation hormones aid in its reproduction.
2. Controlling the activation conditions: The concentration, activation time, and temperature of the activator are key factors, and appropriate conditions should be selected according to the actual situation.
3. Storage method: Activated Bacillus subtilis should be used as soon as possible. If storage is required, it should be refrigerated or frozen below -20 ℃ to ensure its optimal activity.
4. Usage: Prepare a suspension of Bacillus subtilis activator with a concentration of 102-105CFU/mL and apply it to the roots or leaves of plants to enhance their disease resistance.
